INTERNATIONAL CONVENTION FOR SAFETY OF LIFE AT SEA, 1974

Equivalent arrangement accepted under regulation I/5

Nautical charts and publications

Statement by the Government of the Netherlands

The Secretary-General of the International Maritime Organization has the honour to transmit herewith the text of a communication by the Government of the Netherlands on equivalent arrangements accepted under regulation I/5 of the above Convention.

The Secretary-General would be grateful if steps could be taken to bring this information to the attention of the appropriate authorities.


STATEMENT BY THE GOVERNMENT OF THE NETHERLANDS

1 Regulations V/19 and V/27 of the International Convention for the Safety of Life at Sea (SOLAS), as amended and in force as of 1 July 2002, require the carriage of adequate and up to date charts on all ships.

2 An approved Electronic Chart Display and Information System (ECDIS) may be accepted as meeting the chart carriage requirement. Back up arrangements are needed. An appropriate portfolio of paper nautical charts may be used for this, but other back-up arrangements for ECDIS are acceptable.

3 The associated Performance Standards for ECDIS (Resolution A.817(19), as amended) state that when the relevant chart information is not available in the appropriate form (i.e. as electronic navigational charts (ENC)), some ECDIS equipment may operate in the Raster Chart Display System (RCDS) mode (i.e. using raster navigational charts (RNC)). This is also known as the 'dual fuel' mode of operation.

4 It is the view of the Netherlands that if a ship is equipped with a second ECDIS, as back-up for the primary ECDIS, this second ECDIS can be accepted as an alternative for the appropriate portfolio of paper charts, also when sailing in the RCDS-mode in waters for which only RNC's are available. This can be described as a 'dual system/dual fuel' approach.

5 The following conditions will have to be met:

  1. both primary and secondary ECDIS will have to be fully independent and type approved on the basis of relevant and applicable standards (at present: Resolution A.817(19) as amended, and the relevant international standards, namely IEC 60945, IEC 61162-1 and IEC 61174).
  2. the power supply for both primary and secondary ECDIS shall be equivalent to the requirements for the other navigational equipment required by Regulation V/19 of SOLAS, as amended and in force as of 1 July 2002 (at present: Regulations II/42.2.3.2 and II/43.2.4 of SOLAS). So both systems will have to be connected to the main and emergency source of power. Changing of power source shall not require restarting of the ECDIS. In order to achieve this the ECDIS shall also be connected to a reserve power source (UPS mode) with a capacity for at least 30 minutes.
  3. when the reserve source of power is in use, this shall be indicated on the bridge by an audible as well as a visual alarm signal.
  4. only officially issued ENC's and RNC's shall be used (at present: as defined in Regulation V/2.2 of SOLAS and applicable standards).
  5. updating of chart information has to take place at the same interval as presently provided by means of the Notices to Mariners, issued by an authorised Hydrographic Office.
  6. when sailing in waters covered by ENC's as well as RNC's, the ENC's shall be used. When no up to date ENC's or RNC's are available on board, up to date paper charts must be used.
