Quality in Norwegian Charts and Electronic Charts

The Norwegian Hydrographic Service aims to provide charts of the entire Norwegian coast based on modern source data. In Hordaland and the northern part of Norway there are still charts partly based on surveys that are up to 100 years old. To conduct new surveys and provide modern charts of these areas has high priority.

Quality of Norwegian Charts and Electronic Charts in the Waters Around Svalbard

Uncritical use of older charts and modern positioning systems (like GPS) can, because of discrepancies etc. related to the datum, lead to serious mistakes (several hundred meters) during navigation. This further means that the safety margin that sailors should always apply may not be in place as expected.

In some of the older charts, information is given showing the displacement between the graticule of the chart and the World Geodetic System (WGS-84).

New charts for the area are made in accordance to the World Geodetic System (WGS84), while new prints of the older charts retain the existing graticule.

The Norwegian Hydrographic Service reminds the users that the paper charts in the area are on a scale of 1:100 000 or less, and that these charts often form the basis for electronic charts over these waters.

For general information about the quality of the charts around Svalbard, reference is made to The Norwegian Pilot, Volume 7 and the information given in each chart.

The users should be aware that all given corrections (shifts in datum) must be considered to be approximate. The coastline can have considerable discrepancies when compared to the graticule of the chart. Furthermore, the lines of survey for these waters are spaced out to such a degree that the occurrence of undiscovered shoals and rocks cannot be excluded.

Accordingly, navigation in these waters requires extra caution. The navigator should, in keeping with established navigational traditions, use all accessible navigation aids (including radar), continuously compare the observations from the different aids, remain vigilant and ensure that the navigation at all time is carried out applying a sufficient safety margin.

Use of electronic charts does not relieve the navigator from these tasks, and will still require the same professional and critical attitude as with traditional navigation using paper charts.

Changes in glacier fronts and coastline – glaciers used in conjunction with leading lines

The glacier fronts seawards are continually changing. In general, the glacier fronts are receding: observations exist where the glaciers have receded several hundred meters during the last decades.

It is also usual that the glaciers have shorter periods when advancing considerably ("surging glaciers"). Large quantities of ice then move downward from the top of the glacier and collapse below. For this reason contour lines and terrain close to the glacier can deviate from contour lines on the chart. As an example the Fridtjovbreen in van Mijenfjorden advanced about four kilometres from autumn 1995 and the next two and a half years.

In the chart the glacier fronts seawards can refer to a certain year, but such information does not always exist. Changes in the front of a glacier can cause a considerable difference between the existing front and the charted front. In areas where the glacier fronts have receded compared to fronts shown on the chart, no depth information exists.

Also the coastline can change, in particular close to large rivers. The user should bear this in mind and ensure that the utmost care is taken when navigating close to glacier fronts and river estuaries.

Glaciers are in some cases used as a reference in conjunction with leading lines. These can be old and well-known points which have been used for decades. Changes in the form and outline of glaciers might, however, cause changes in the reference point. Where glaciers are used as reference points great care must be taken during the navigation, and it must always be done in conjunction with other navigation aids.

Unsurveyed areas

Surveys are incomplete in some areas of Svalbard. Large areas are not surveyed at all. These areas are presented as white areas limited by a red dashed line and the text "Unsurveyed". We will strongly advise against any navigation in these areas – even if some soundings and underwater rocks are shown. The areas should be referred to as unsurveyed.

Areas inside the 50 meters depth contour in areas with old surveys are not safe. We advise against all navigation in such areas.

In newly surveyed areas of Svalbard, the surveying is performed at depths deeper than 3 meters only. Shallow areas are not surveyed.

Refer to the Warnings and Source diagram in the Charts.

Mixture of old and new depth data

To ensure optimal use of resources, the Norwegian Hydrographic Service has conducted external market research in order to ascertain users' evaluation of how remaining areas should be prioritized. The recommendations are taken into account in the production plans. This means that there will be a mixture of old and new depth data within the same ENC or paper chart.

2 About Etterretninger for sjøfarende (Efs)

The Norwegian notices to mariners, Etterretninger for sjøfarende (Efs), is published twice a month. The Efs provides information on changes or defects in aids to navigation, discovery of new dangers and on shortcomings in Norwegian charts or publications, navigational warnings, gunnery exercises or other information of interest to mariners. I addition to temporary (T) and preliminary (P) notices in Norwegian waters.

The complete pdf editions of the Efs are accepted as an official Norwegian "notices to mariners" by the Norwegian Maritime Authority, on the same terms as the former printed Efs.

The Efs and tracings are available, free of charge, through the digital Efs service, kartverket.no/efs.

2.1 Professional users

Users are responsible for downloading the latest pdf edition of the Efs on kartverket.no/efs.

2.2 Digital Efs Service

The digital Etterretninger for sjøfarende (Efs) service has made it possible for the users to easily search for chart corrections and notices for each of the Norwegian charts. Searches can be saved for your next visit on the site. The Efs editions and tracings are available for download, free of charge.

It's possible to search for notices published in the Efs back to 2010. Please note that errors may occur in older notices, then it's the pdf edition of the Efs that's current.

Notices published before 2010 are only available through the pdf editions of the Efs.

2.3 Efs – Contents

All published information and chart corrections in the Norwegian Notices to Mariners, Etterretninger for sjøfarende (Efs) refer to the latest edition of the chart.

Contributors of nautical information to the Efs

The main contributors of nautical information to the Efs, can be divided into three groups:

  • Government agencies such as: The Norwegian Coastal Administration, The Norwegian Public Roads Administration, The Directorate of Fisheries, Port Authorities, and local municipalities. Typical data are lights and aids to navigation, bridges, fish farms, quays, fillings and moles, etc.
  • Private entrepreneurs constructing new or making changes to existing infrastructure which may affect the safe navigation at sea. This includes new/modified quays, marinas, moles, marine farms, fillings, overhead cables, submarine cables, etc.
  • Private companies or persons making constructions at sea that are not relevant for safe navigation, but where the object can be damaged by anchoring or by fishing activity, such as submarine pipelines, cables or oil-related equipment on the seabed.

The charts affected by a notice are listed in the notice heading and is repeated in the bottom of the notice. A star (*) adjacent to the number of a notice indicates that the notice is based on Norwegian original information.

Chart corrections are translated into English. Other notices of importance for the navigation are translated into English in a shortened version.

The contents in Etterretninger for sjøfarende (Efs) are sorted by

All corrections of significant navigational importance and other temporary (T) and preliminary (P) notices regarding sailing in Norwegian waters are announced in the Efs:

See illustration of the Norwegian Coastal Areas (pdf, 180 kB).

See illustration of the Norwegian Ocean Areas  (pdf 344 kB).

Temporary (T) and Preliminary (P) Notices

A Temporary (T) Notice to Mariners is used to promulgate navigationally significant information that will remain valid only for a limited period. All T notices which have an indicated time will not be repeated unless any changes in time or other important changes.

A Preliminary (P) Notice to Mariners is issued to promulgate navigationally significant data early that is of importance to navigation and which in the future will result in a permanent chart correction.

These notices are indicated by (T) or (P) before the notice number, the charts will not be corrected, but an ECDIS revision (ER) are available for Electronic Charts. All active T and P notices are available on the Efs Internet service, kartverket.no/efs.

Positions

Positions are given in World Geodetic System (WGS84 DATUM) in degrees, minutes and decimals of minute.
Bearings are true, reckoned clockwise from 000° to 360°.
Light sectors: Bearings referring to a light sector are given in true degrees as observed from sea.
Distances are given in meters (m) or nautical miles (M).
Depths and heights are given in metres.

Abbreviations

The publication Symbols and Abbreviations on Norwegian Maritime Charts provides an overview of symbols and abbreviations used for Norwegian nautical charts. The text is in both Norwegian and English.

2.4 Nautical Publications

Norwegian nautical publications, in addition to the Norwegian notices to mariners, Efs:

«All ships shall carry adequate and up-to-date charts, sailing directions, lists of lights, notices to mariners, tide tables and all other nautical publications necessary for the intended voyage.» (See SOLAS Consolidated Edition, Chapter V, Regulation 27).

3 Tracings

The Norwegian Hydrographic Service offers a tracing service. Tracings are supplements to the Efs notice, and are meant to aid the mariner when correcting charts and to reduce the workload. We offer tracings for charts in the Main- and Harbour chart series.

The tracings can be downloaded from the Efs Internet service kartveket.no/efs, free of charge. The users themselves must print the tracings. It is possible to download all tracings corresponding to the latest issue of the Efs in the pdf archive.

An instruction video on how to use tracings is available in Norwegian.

Tracing User Guide

The tracings are meant as a supplement to the notices to mariners only. They should be used in conjunction with the corresponding notice. Which notice the tracing corresponds to, is written on the lower right corner of the tracing. Which chart the tracing refers to, will also be indicated in the same area of the tracing.

When printing the tracing, make sure the printer is set up to print with no scaling. The tracing should be placed correctly on the chart primarily by means of the tracing grid. The tracing grid corresponds to the chart grid. Latitude and longitude are noted on the tracing to make it easier to place it.

The charts are printed on paper which is a living material. The size of the chart will change with the weather, and the user might observe a difference in size of the chart and the tracing. When this error is observed the user should place the tracing by using the grid intersection closest to the object inserted, amended or deleted. If the grid intersection is too far away from the object, the tracing should be placed by means of the reference features closest to the object being amended. If the tracing is placed in this way, the user must insure that the tracing and chart grids are parallel to each other. This is especially important when making amendments to light sectors in order to ensure that the sector angles are drawn correctly.

When the tracing has been placed correctly you can use the pointed end of dividers/compasses to perforate the tracing and mark in the chart where the new appropriate object should be placed. The deletion of an object will be shown in the tracing by use of a deletion symbol (x) and a corresponding text. When the tracing is placed on the chart, the object to be deleted will lie directly beneath the deletion symbol.

4 Nautical Charts

Nautical charts are the foundation for safe navigation. When navigating narrow channels, charts in the largest scale available should always be used as these give the best and most detailed information about the waters. Smaller scale charts are very simplified and are not edited to support navigation in coastal waters.

The publication date can be found in the title area. This date will provide the user with a guideline to how reliable the chart is. Please check the "Printing and Maintenance" section for further information.

Reliability

Due to the rapid development of both shipping and electronic navigational aids, the demand for reliability in nautical charts is now greater than ever. The chart reliability is very much dependent on the technology available to the hydrographical service.

Charts based on older surveys do not fully meet today's reliability standards. Therefore, Norwegian Hydrographic Service frequently receive discrepancy reports. These reports are promptly handled.

If required, a notice will be published in the Etterretninger til sjøfarende (Efs). Nautical charts are updated at the next print.

Updating and Printing of Charts

The year of publication is shown in the title block. This information will help the mariner in judging the reliability of the chart. As charts are subject to frequent changes, they are reprinted regularly.

The month and year of printing as well as the latest Notices to Mariners it is updated to,is shown in the lower left-hand corner of the chart. See example below.  "POD: 22. Dec 2016. Corrected to "Efs" No 23/16." means that map file is generated 22.12.2016 and the notices published in Efs no. 23/16 is corrected in the chart.

Hydrographic charts on paper are now sold only as POD-Charts (Print on demand) and must be ordered from authorized POD dealers. Charts are subject to frequent changes, and important amendments are continuously published in the Norwegian Notices to Mariners, Etterretninger for sjøfarende (Efs).

It is therefore the responsibility of the mariners to keep their charts updated in accordance with Efs after the date of printing. A Norwegian chart is updated when all corrections from the Efs concerning that chart are applied.

Overview with printing dates for Norwegian charts (pdf).

Print on Demand (POD)

The Norwegian Hydrographic Service offers a Print on Demand (POD) service. Print on Demand service is offered for all Norwegian charts and can be purchased from approved suppliers of The Norwegian Mapping Authority's maps and charts.

Traditionally, paper charts were issued every few years. As time passes, there would be messages from the Norwegian Notices to Mariners, Etterretninger for sjøfarende (Efs), that were not reflected in the chart at selling time. This meant that even though the chart was bought today, many important corrections could have been issued since the chart was printed, and mariners had to manually update the chart with the Efs updates since the chart was published. With POD this is no longer necessary, as POD-charts are automatically and continuously updated to the latest Efs.

When a POD chart is purchased, the mariner only has to review the Efs’ published after the POD production, in order to have a fully updated chart. This will typically be limited to the latest Efs.

Chart updating starts as soon as an Efs is published. All updates shall be performed before the next Efs is issued (i.e. during a 14 day period). POD charts may also include updates that have not yet been published in an Efs.

POD: "Print on Demand" is printed in red text on the left and right side of the chart frame. A text box in the lower left corner displays different dates and Efs reference.

Source diagram in charts

The source diagram printed in the chart title box shows when the survey was performed and the quality of the depth data. This provides an indication of the accuracy of the product. Areas surveyed before about 1960 did not receive full seafloor coverage and depth anomalies may be expected.

There may be undiscovered depths in older surveyed areas. Caution must therefore be taken when sailing in these areas. It is dangerous to sail outside marked areas/recommended track.

4.1 Symbols and Abbreviations

The publication Symbols and Abbreviations on Norwegian Maritime Charts provides an overview of symbols and abbreviations used for Norwegian nautical charts. The text is in both Norwegian and English.

Projections

All nautical charts in the scale 1:50 000 or larger are projected in Gauss conform cylinder projection (Gauss-Krüger). Nautical charts in scales less than 1:50 000 are usually constructed in a Mercator projection.

Chart Scale

Norwegian Hydrographic Service publishes navigational charts over Norwegian and bordering waters. The charts are mostly based on Norwegian hydrographic surveys.

Navigational charts are published in the following scales:

  • Main chart series 1:50 000 – 1:100 000
  • Harbour chart series 1:5 000 – 1:25 000
  • Coastal chart series 1:200 000 – 1:350 000
  • General chart series 1:700 000 – 1:10 000 000

Chart datum

From Utsira and northwards, including Svalbard, the chart datum (vertical) is identical to "lowest astronomical tide" (LAT). In Oslofjorden (north of Drøbaksundet) the chart datum is 30 cm below LAT, and between the Swedish border and Utsira the chart datum is 20 cm below LAT.

Meteorological conditions can cause depths to be less than specified in the chart. More information can be found in the publication Tide Tables for the Norwegian Coast and Svalbard (Tidevannstabeller for den norske kyst med Svalbard) and in the Norwegian pilot guide sailing directions, Den norske los, Volume 1, Alminnelige opplysninger.

On the Swedish side of nautical chart no.1 the soundings refer to a different datum, and they are approximately 60 cm shallower than the Norwegian ones. When navigating Swedish waters, Swedish charts should be used. Observed water levels and water level forecasts for the next days are available at Se havnivå. The service also provides tide tables and vertical reference levels.

Place names

In some charts the spelling of place names are out dated. Place names are currently under revision and creation.

When new releases of charts are published, all place names will be revised and updated.  It will therefore take a while before all the charts are updated.  There is currently a transition period with maps and publication using both the old and new spellings of certain place names.

In new editions of charts place names a will be updated in accordance with the laws on place names.

Leading Line

Leading lines indicate that waters are commonly used as fairways.

Ferry route

To inform mariners of crossing traffic, ferries are marked on the chart by the contours of a red ferry along a dashed line. This symbol is not to be regarded as a recommended track.

Overhead- and Submarine Cables

Overhead cables, telephone and power lines that cross salt water are inserted onto the nautical charts after if Norwegian Hydrographic Service is notified about them. Notices about new cables are frequently issued in Efs.

As both overhead and underwater cables may carry very high voltages, it is important that the navigator show extreme caution when navigating near them. The navigator should also be aware that new cables may not be displayed in the chart.

Underwater and overhead cables which are installed after the latest print of the chart have to be inserted manually.

Depth Contours

The depth contours have been drawn through points with the same depth, and have then been generalized. Thus, the contours may not always be accurate, but they do show the nature of the topography of the sea floor. By generalizing the depth contours, the line is always moved towards deeper waters to ensure safe navigation.

In areas where the topography is complicated, normal cartographic practice is to merge or generalize the depth areas. This is very common in the complex Norwegian waters.

Soundings

A sounding is the depth in a position relative to the chart's vertical datum. Its value is a positive number. Its position is the centre of the number.

Underwater rocks

An underwater rock is an area of limited size which stretches towards the surface, but is deeper than 0,5 m below the chart's vertical datum.

0 – 9,9 m are displayed with decimals.

10 – 20 m are rounded down to the nearest meter

> 20 m are displayed as soundings, in italics.

Rock awash

A rock awash is a rock which lies between chart's vertical datum and 0.5 meters below chart's vertical datum.

Rock

A rock is covered and uncovered by water. Its height is above the chart's vertical datum.

Danger Line

The Norwegian "danger line in general" is still in use in some areas of several of our charts.

In sheltered waters, it is a dotted line which indicates an approximate depth of 6 m.

In more open waters, it may be drawn in deeper waters, normally 6 to 20–30 m.

Intertidal Areas Above Chart Datum

The area of the seafloor between 0,5 m below the chart's vertical datum and the coastline. This area is limited by the Charts Low Waterline.

Coastline

The coastline (the border between sea and land) in Norwegian charts is defined to be Mean High Water.

Depth Over Wreck

Wrecks and large debris on the seafloor may over the course of time have shifted so much that the depth above such wrecks may be less than the charted depth.

4.2 Reference Level for Vertical Clearances

The reference level for vertical clearances in Norwegian charts is the highest astronomical tide (HAT). Analysis has shown that the tidal levels in Norway often exceed this level. Therefore extra safety margins should be added by navigators in order to ensure safe navigation.

By increasing the safety margins by the following amounts in the designated areas, the vertical clearance should be safe:

  • Inner Oslofjorden (North of Drøbaksundet): 80 cm
  • From the Swedish border to Hordaland: 50 cm
  • From Hordaland to the Russian border: 30 cm

Observed water levels and water level forecasts for the next days are available at Se havnivå. The service also provides tide tables and vertical reference levels.

More information on the Norwegian tides can be found at:

www.sehavniva.no

Read more about tidal waters.

4.3 Submarine Cables, Overhead Cables and Submarine Pipelines

Both submarine and overhead cables can carry very high voltages, and mariners should be careful when navigating near them. They should also be aware that submarine and overhead cables may not be displayed in the charts. The vertical clearance may also vary due to extreme weather conditions.

Damage to Submarine Cables

Mariners should avoid anchoring and fishing in areas where a submarine cable is displayed on the chart. Anchors and fishing gear can cause severe damage, and disrupt telecommunications or the power supply.

Damage to Submarine Pipelines

Gas from a damaged oil or gas pipeline could cause an explosion, loss of a vessel's buoyancy, serious pollution or other hazards.

Pipelines on the seafloor are not always buried and their presence may effectively reduce the charted depth by as much as 2 meters. They may also span seabed undulations and cause snagging, putting a vessel in severe danger.

Trawling across pipelines at angles of 45° or more is recommended.

4.4 Marine Farms. Moorings

Fishing within 100 m, and sailing within 20 m of a marine farm is prohibited.

The chart symbol for a marine farm is used only where a license has been given by the Directorate of Fisheries. A marine farm may not be located in the given position as one company may have been given several licenses and alternate between these locations. Some marine farms may not be charted.

The moorings may stretch for several thousand meters from the marine farm. Not all of them are displayed in the charts.

Additional information can be found at the Directorate of Fisheries' website.

5 Electronic Navigational Charts (ENC)

In connection with new surveying of the Norwegian coast, the Norwegian Hydrographic Service is prioritizing the publication of electronic navigational charts authorized for navigation. The international designation of such charts is ENC (Electronic Navigational Chart).

ENCs are produced in accordance with the International Hydrographic Organization's (IHO) S-57 standard, which is applied by all hydrographic offices world-wide for the production of corresponding electronic navigational charts for their waters.

ENCs for the entire Norwegian coast are available through authorized PRIMAR distributors. Information about coverage and overview of distributors is available from www.primar.org.

5.1 Electronic Chart Display and Information System (ECDIS)

ECDIS is a certified navigation system meeting SOLAS requirements to navigational equipment pursuant to certain criteria. If an ENC is installed on this type of system and kept updated, it may be used for navigation in the same manner as an updated paper nautical chart.

Other types of unofficial electronic charts, for example charts produced by private industry or raster charts, can only be used as a supplement for navigation.

The following back-up systems are approved for use on Norwegian vessels:

  1. Updated paper nautical charts, or
  2. ECDIS No. 2 connected to an emergency power source.

IMO requirements for mandatory use of ECDIS

The International Maritime Organization's (IMO) Maritime Safety Committee (MSC) approves provisions regarding the mandatory use of ECDIS, depending on the type of vessel and its size.

5.2 Official Norwegian Electronic Navigational Charts (ENC) for Norwegian Waters – Content and Updating

Official electronic navigational charts (ENC) are vector charts produced in compliance with the specifications given by the International Hydrographic Organization, and are approved by a national hydrographic office.

The sources for Norwegian ENCs are either digitalized or scanned analog charts, or a database. The data is compiled into a seamless database in which each ENC is a cell. Each cell is identified by a unique number.

The content of charts and ENCs in the same area is not always identical. The ENC often contains more detailed data.

Depths along the quay

Quay depth is not a object class in the ENC. They are regular soundings showing its true position. Quay depths are taken either on the quay or two meters away from the quay depending on when the measurements were taken. Quay depths maybe presented slightly away from the quay in the electronic navigational chart (ENC) in order to improve readability in ECDIS.

Update Files (ER Updates)

An advantage with ENCs is the possibility for automatic updates. Update files (ER) are issued every fortnight. Within a 14 day period, all notices from the last Notice to Mariners (Efs) will be included. The ERs may also include updates that have not been issued in the Efs.

Temporary (T) and preliminary (P) notices are distributed for the ENCs in the same way as other updates. All ER updates are distributed through PRIMAR. For larger updates New Editions of an ENC will be issued. A New Edition may also be issued for technical reasons.

Terms Used

New dataset: ENC dataset that has not been issued for navigational purposes earlier.

Update: Amendments to existing dataset.

New edition: It also includes new data that have not been released earlier, in addition to all the previous updates.

Warning

Use of modern equipment makes it possible to extend the use of nautical chart information beyond what it is intended for. We strongly advise against this.

It is at all times the mariners own responsibility to familiarize themselves with and use the information in a chart in a responsible manner. Do take into consideration the constraints of the information the charts provides.

Report Feedback on Norwegian ENCs

Report errors, omissions or suggest improvements on the Norwegian Electronical Navigational Charts (ENC) in the web-based feedback system ENC Improver.

ENC Improver has been designed to provide users with a simple system to give feedback on Norwegian ENCs. Everybody who has an ENC license for navigation will receive user access to ENC Improver through their supplier.

Add a point on the chart in ENC Improver and describe the problem. A monitoring system is in place to follow up received feedback. To submit feedback, Internet access is required.

In addition to ENC Improver, errors, omissions or suggestions for improvements on the Norwegian ENCs can also be sent to kundesenter@kartverket.no.

User Bands

Norwegian ENCs are divided into the following user bands:

6 Berthing > 1:4000 3999 and larger < 0.25 NM

5.3 Zones of Confidence - ZOC Diagram

The data sources for an ENC will for many areas be based on old hydrographic data with inferior positional accuracy compared to what is possible with modern technology. These areas are identified by the use of Zones of Confidence (ZOC).

In digital charts the data quality is specified in Zones of Confidence (ZOC).

The ZOC diagram describes the quality of the bathymetry in the different areas. There are five quality categories in the ZOC diagram (A1 to D).

Until autumn 2013, mainly category B and C are used for Norwegian coastal waters based on the following classifications: ENCs with source data from older surveying (before 1960) are given ZOC value C, while ENCs with source data from surveying younger than ca 1960 are given ZOC value B.

From 1st of January 2014 the areas measured with multibeam sonar and which otherwise meets the requirements will be given the categories A1 or A2. The delimitation of the different zones will be added in the ENCs to always show which zone you are in.

Navigators must show great care when using (D)GPS and electronic charts in areas with older surveys as accuracy and completeness of the depth indicators are not in accordance with modern standards.

Additionally, the navigators should ensure that navigation at all times is conducted with good safety margins and in accordance with proper navigational practices.

Remarks:

To decide on a ZOC Category, all conditions outlined in columns 2 to 4 of the table must be met.

Explanatory notes quoted in the table:

1 The allocation of a ZOC indicates that particular data meets minimum criteria for position and depth accuracy and seafloor coverage defined in this Table. ZOC categories reflect a charting standard and not just a hydrographic survey standard. Depth and position accuracies specified for each ZOC category refer to the errors of the final depicted soundings and include not only survey errors but also other errors introduced in the chart production process. Data may be further qualified by Object Class 'Quality of Data' (M_QUAL) sub-attributes as follows:

a) Positional Accuracy (POSACC) and Sounding Accuracy (SOUACC) may be used to indicate that a higher position or depth accuracy has been achieved than defined in this Table (e.g. a survey where full seafloor coverage was not achieved could not be classified higher that ZOC B; however, if the position accuracy was, for instance, ± 15 metres, the sub-attribute POSACC could be used to indicate this).

b) Swept areas where the clearance depth is accurately known but the actual seabed depth is not accurately known may be accorded a 'higher' ZOC (i.e. A1 or A2) providing positional and depth accuracies of the swept depth meets the criteria in this Table. In this instance, Depth Range Value 1 (DRVAL1) may be used to specify the swept depth. The position accuracy criteria apply to the boundaries of swept areas.

c) SURSTA, SUREND and TECSOU may be used to indicate the start and end dates of the survey and the technique of sounding measurement.

2 Position Accuracy of depicted soundings at 95% CI (2.45 sigma) with respect to the given datum. It is the cumulative error and includes survey, transformation and digitizing errors etc. Position accuracy need not be rigorously computed for ZOCs B, C and D but may be estimated based on type of equipment, calibration regime, historical accuracy etc.

3 Depth accuracy of depicted soundings = a + (b*d)/100 at 95% CI (2.00 sigma), where d = depth in metres at the critical depth. Depth accuracy need not be rigorously computed for ZOCs B, C and D but may be estimated based on type of equipment, calibration regime, historical accuracy etc.

4 Significant seafloor features are defined as those rising above depicted depths by more than:

 -DepthFeature
a. <40 m 2 m
b. >40 m 10% depth

A full seafloor search indicates that a systematic survey was conducted using detection systems, depth measurement systems, procedures, and trained personnel designed to detect and measure depths on significant seafloor features. Significant features are included on the chart as scale allows. It is impossible to guarantee that no significant feature could remain undetected, and significant features may have become present in the area since the time of the survey.

5 Typical Survey Characteristics - These descriptions should be seen as indicative examples only.

6 Controlled, systematic surveys (ZOC A1, A2 and B) - surveys comprising planned survey lines, on a geodetic datum that can be transformed to WGS 84.

7 Modern survey echo sounder - a high precision single beam depth measuring equipment, generally including all survey echo sounders designed post 1970.".

6 Tidal Waters

Observed water levels, water level forecasts, tide tables and vertical reference levels for the Norwegian coast are available at Kartverket’s service Se havnivå

The water level has one contribution from the predictable tide, due to the moon and the sun, and one meteorological contribution (the surge) due to weather effects such as pressure and wind, The water level forecast combines the tide with forecast for the meteorological contribution.

The Lowest Astronomical Tide (LAT) and the Highest Astronomical Tide (HAT) refers to the lowest and highest tide level which can be predicted to occur under average meteorological conditions. LAT and HAT are determined by finding the lowest low water and the highest high water from 19 years of predicted tides.

Reference Level for Depths and Heights in the Tidal Tables

The vertical Chart Datum in Norwegian waters is based on the Lowest Astronomical Tide (LAT). In areas where the meteorological contribution can dominate the water level for longer periods of time, an extra safety margin has been added so that the datum is lower than LAT.

For Norwegian waters, the Chart Datum is defined as follows:

  • From Utsira and north to the Russian border (including Svalbard) Chart Datum equals LAT.
  • From the Swedish border to Utsira, Chart Datum is 20 cm lower than LAT.
  • In inner Oslofjorden north of Drøbaksund, Chart Datum is 30 cm lower than LAT.

This definition of Chart Datum was introduced into the Norwegian charts in January 2000. The datum of charts made prior to this date refer to Mean High Water Spring.

 

 

7 Information from the Norwegian Coastal Administration

The Norwegian Coastal Administration (NCA) is managed by the Coastal Director and head office of the agency. The regions perform operational tasks and shared task on behalf of Coastal Director. NCA has eight operating units: five regions, shipping, emergency centre and head office.

Read more about the Norwegian Coastal Administration at kystverket.no.

Norwegian List of Lights

The latest issue of the Norwegian list of lights (Fyrlisten) was issued in 2018 and supersedes all previous editions.

A digital version of the Norwegian list of lights is updated every morning. You can download the continuously updated Norwegian list of lights as a pdf at kystverket.no.

The Norwegian list of lights (Fyrlisten) describes maritime navigation marks which emit light signals on land and at sea, as well as information about other aids to navigation.

Transition to IALA Standard

In the period 2019 to 2025, the Norwegian Coastal Administration will be reorganizing the sectors of around 1900 sector lights in compliance with the standard defined by IALA (International Association of Lighthouse Authorities).

It is of great importance to study Notice to Mariners (Efs) carefully, and that all navigational charts are updated. When pilot is onboard or ship is passing through a VTS area, it is important to follow their instructions.

More information about the IALA standard and contacts in the Norwegian Coastal Administration.

Buoys and Beacons

Most of the navigation aids along the coast are automated and without security. It is therefore essential that seafarers notify Norwegian Coastal Agency (NCA) of irregularities in navigation systems. Other acute and/or unexpected events that may be of danger to shipping must also be reported.

Examples of acute and/or unexpected events are drifting objects, undescended high voltage cable, stranded ships, sunk ships and drifting gear. Messages is sent to the the Norwegian Coastal Administration, which national coordinator for navigational warnings.

Mariners are advised that beacons must not be used for mooring. This can cause the beacon becomes damaged or out of position.

Racon

A modern Racon normally respond to both "X" and "S" frequency band radars. The range is dependent on the elevation of the radar antenna and of the transponder. Response intervals will vary depending on the characteristics of the racon. For example 18/30s means that the racon will respond for 18 seconds, and be nonresponsive for 12 seconds every 30 seconds.

A list of Racons on the Norwegian coast can be found in the Norwegian List of Lights.

Please report any discrepancies to the Norwegian Coastal Administration, which national coordinator for navigational warnings.

Floodlights (IB)

Floodlight has a steady yellow or white light that illuminate an area. This area can be an odd, rock, pier head, bridge piers or structure as a lantern is equipped.

The purpose of the diffuser is to provide the crew a certain effect of navigation at day, where one can better see and judge the distance to a restricted area and also see an illuminated daymark even though it is dark. Often this amplified using reflectors and/or white colour.

NCA Maintenance Vessels

To be able to perform their work, it is sometimes necessary for the Norwegian Coastal Administration's maintenance vessels to moor beside navigational aids. During these operations, these maintenance vessels will have restricted ability to maneuver, and the crew may be conducting dangerous operations.

In order to avoid injury and damage, other vessels are requested to give these maintenance vessels as wide a berth as possible when passing them and to reduce speed accordingly.

7.1 Navigational warning system

The navigational warnings are transmitted over the coastal radio by telephony and NAVTEX, and they provide mariners with notices of incidents/conditions that are hazardous to shipping.

Report Irregularities and Obstructions

Many of the navigational aids along the coast are automated and unmanned. It is therefore important that mariners notify the Norwegian Coastal Administration of any irregularities in the navigational installations.

Other acute and/or unexpected incidents that may be hazardous to shipping must also be reported. Examples of acute and/or unexpected incidents are drifting debris, fallen high voltage cables, grounded vessels, sunken vessels and drifting fishing equipment.

Reports shall be sent to the national navigational warning system (NAVCO):
Tel.: 22 42 23 31 (24 hrs.)
Fax: 22 41 04 91 (24 hrs.)
E-mail: navco@kystverket.no

Active navigation warnings

The Norwegian Coastal Administration (Kystverket) provide navigation alerts regarding marine conditions affecting navigation at sea.

General Navigation Warnings

Norway, through The Norwegian Coastal Administration, is involved in international cooperation on navigational warnings. The Global Maritime Distress and Safety System (GMDSS) provides information on shipping and the communication of emergencies to increase safety at sea. GMDSS includes security notifications including World-Wide Navigational Warning Service (WWNWS) alerts.The UN Maritime Organization IMO (International Maritime Organization) manages WWNWS. IMO regulates the entire alert service, in terms of both irregularities and events to be notified, and the type and format alerts take.

The Navigation Warning Sysytem (WWNWS) Includes:

  • NAVAREA Warnings – Maritime Safety messages sent by Safety
  • Net satellite (INMARSAT)
  • Coastal Warnings - NAVTEX 518 KHz and Telephone
  • Local Warnings - NAVTEX 490 KHz and Telephone
  • NAVAREA warnings.NAVAREA Sea Warnings
  • Navigational warnings that only affect sea-going vessels

These alerts and warnings are broadcast from a satellite (SafetyNet) in English. For the Norwegian NAVAREA, NAVCO ensures that the content of the notification is forwarded to the United Kingdom, which is area coordinator for Navarea-1. The United Kingdom issues all NAVAREA alerts in NAVAREA-1 at the request of national coordinators in the area.

Coastal Warnings

A coastal warning is a navigational warning that is important to traffic along the Norwegian coast and in the fjords.

The warnings are distributed via Navtex in English and by telephone from the coast radio stations in English and Norwegian. The national coordinator (NAVCO) issues Norwegian coastal warnings. There are strict guidelines for what constitutes a coastal warning. Incidents must be of a sudden nature and pose a danger to shipping.

Notification of planned and non-critical events is made through the Norwegian Notice to Mariners (Efs).

Notification of events that are not a risk for shipping, but which endanger other constructions or life and health may be made through the Efs in special cases.

Local Warnings

Local Warnings are navigation warnings that only affect small vessels in areas outside the main fairways or warnings that do not come under the category of coastal warning, due to not being a danger to shipping and of a sudden nature.

For example, diving work is not a danger to shipping, but the diver may be at risk if the dive site is operated by vessels.

Local warnings on 490 KHz has not been launched in Norway (neither in Denmark or Sweden), but is used I the UK, Germany, Portugal and Iceland. The Coast Radio in Norway is registered and has received transmission codes. There are already Navtex receivers on the market that take both frequencies 518 og 490 KHz. As a test project, local warnings are sent out via telephone in special case.

The national coordinator (NAVCO) issues local warnings during normal office hours.

Navarea

Navigation warnings in the Norwegian coastal areas is covered by these six 518 kHz NAVTEX service areas:

  • Svalbard (A)
  • Bodø (B)
  • Vardø (C)
  • Rogaland (L)
  • Jeløya (M)
  • Ørlandet (N)

For warnings in the oceans areas see NAVAREA XIX.

The publication of navigation notifications on the website is not intended as a substitute for , or alternative to NAVTEX, and does not relieve the captain from their responsibility to comply with MSI broadcasts in accordance with the provisions of SOLAS.

7.2 Vessel Traffic Services

The VTS contact information is listed at the Norwegian Coastal Administration's website, kystverket.no.

Norway operates five Vessel Traffic Service Centres through the Norwegian Coastal Administration. These cover ship traffic along the Norwegian coast.

VTS Centres:

  • Fedje VTS
  • Kvitsøy VTS
  • Brevik VTS
  • Horten VTS
  • Vardø VTS

Read and download the document "Regulations relating to maritime traffic in specific waters" (English translation) at kystverket.no.

Read the regulations relating to maritime traffic in specific waters, Sjøtrafikkforskriften, in Norwegian at lovdata.no.

7.3 Pilot Boarding

The Norwegian Coastal Administration is responsible for the state pilotage service. Pilot bookings are made electronically in the SafeSeaNet Norway messaging service on www.shiprep.no.

For more information about the Norwegian pilot services, visit the Norwegian Coastal Administration's website kystverket.no.

See an overview of Norwegian pilot boarding areas at lovdata.no.

The Pilotage Act

The Compulsory Pilotage Regulations stipulate which vessels are subject to compulsory pilotage and the waters where the requirement applies. The compulsory pilotage requirement can be met by either employing a pilot or by use of a Pilot Exemption Certificate.

The general rule is that all vessels with a length of 70 metres or more are subject to compulsory pilotage when operating in waters within the baselines. Certain areas are nevertheless exempt from compulsory pilotage for vessels in transit to or from the pilot boarding area. For certain categories of vessels stricter rules apply, such as passenger vessels and vessels carrying dangerous and polluting cargo.

The Pilotage Act applies to Norwegian internal waters and the territorial sea, and it has also been made applicable to Svalbard.

Download the documents "Compulsory Pilotage Regulations – unofficial translation" and "Pilotage Act – unofficial translation" at kystverket.no.

Read the Pilotage Act, lospliktforskriften, in Norwegian at lovdata.no.

7.4 Ice Service

The Norwegian Coastal Administration provides the national Ice Service, which has two main tasks:

  • Provide ship traffic with updated information on ice conditions in Norwegian waters from the Swedish border to Kristiansand.
  • Icebreaking in main and secondary fairways outside port areas.

Ice reports are available from December 1 to March 31.

More information about the Norwegian ice service is available at kystverket.no.

8.1 Routines for Maritime Safety Information (MSI)

Vital and very important navigational warnings and storm warnings (force 9 and up), are notified by DSC on MF and VHF followed by advertising on VHF Ch 16 and 2,182 kHz immediately after receipt from the Meteorological Institute or The Norwegian Coastal Administration. Warnings are then readout on the announced working channels.

Important navigational warnings and strong wind warnings (less than force 9) are broadcast only on VHF Ch 16 and 2,182 kHz before being readout on the advertised working channels. Strong wind and storm warnings are repeated twice in subsequent bulletins.

Navigation alerts are repeated in the two subsequent bulletins, and then once a day (10:33 UTC) for 7 days. Besides this, the numbers of valid navigational warnings which are still inforce are broadcast in regular bulletins until cancellation.

Channel 260 (Rogaland) is not used for the regular airing of MSI messages as the area is covered by the transmitters in Farsund and Bergen.

Navtex

In the Navtex system, vital and important messages are sent immediately upon receipt. Navigation warnings are repeated in the regular bulletins until cancellation. Strong wind and storm warnings are repeated once in the subsequent regular airtime.
