All vessel should keep an updated list of nautical publications as per regulations set by IMO. If a new edition is published, this too shall be entered along with edition on board to keep a check until it is received. The Nautical Publications will include Sailing Directions, List of Lights, Tide Tables, List of Radio signals, Nautical Almanac, Charts Catalogue, Mariners Handbook and others necessary for the safe navigation of the ship.
To correct the Sailing Directions (Pilots) , it is recommended that the correction index on the inside of the front cover is used to record weekly corrections (from Notices to Mariners / Digitrace) and also the affected pages in the Sailing Direction.
The corrections are filed in a dedicated file, in individual sections for each Sailing Direction on board. When using the Sailing Direction, reference should be first made to this index and then if any corrections are applicable to the concerned page, same can be consulted in the file.
For corrections to Admiralty List of Lights & Fog signals and Admiralty List of Radio Signals, these should be pasted on top of the existing (superseded) entry in the publication and the correction index at the front of the publication updated.
Smaller corrections may also be done by Pen, in the Publication.
Vessel must correct the ECDIS by inserting the disc received regularly from company in the computer. After correction, this should be written on the disc face by permanent marker and all such disks retained on board for 1 year.
Please note the following navigation warning received today from the UK MCA on safe navigation. Mariners are advised that ECDIS (Electronic Chart Display and Information System) may not display some isolated shoal depths when operating in "base or standard display" mode. Route planning and monitoring alarms for these shoal depths may not always be activated. To ensure safe navigation and to confirm that a planned route is clear of such dangers, mariners should visually inspect the planned route and any deviations from it using ECDIS configured to display "all data".
The automated voyage planning check function should not be solely relied upon. The International Hydrographic Organization (IHO) is leading technical action to resolve this matter.
Verification Of Corrections
The Master should verify the corrections from each Notice to Mariner on random charts or publication.
A prudent master shall also verify on a random basis, the ECDIS (where fitted) corrections by correlating with a paper chart notice.
Admiralty Chart correction procedure
There are currently two methods of carrying out electronic chart corrections, either via Weekly Updates, CD or downloaded weekly from a recognised electronic chart supplierís data. The preferred method will be decided by the Management Office depending on the communications equipment onboard the vessel but in the majority of cases the lack of internet access will determine the update CD as the best option....
