Standards in Force
Introduction
SOLAS regulations V/18 and V/19 requires that, to meet requirements for carrying charts (in terms of SOLAS), the Electronic Chart Display and Information System (ECDIS) equipment must conform to the relevant IMO performance standards. ECDIS units on board are required to comply with one of two performance standards (either IMO resolution MSC.232(82) or MSC.530(106)), depending on the date of their ECDIS installation.
Where an ECDIS is being used to meet the chart carriage requirements of SOLAS, it must:
- be type-approved;
- use up to date Electronic Navigational Charts (ENCs);
- be maintained so as to be compatible with the latest applicable IHO Standards; and
- have adequate, independent back-up arrangements in place.
The applicable ECDIS related standards can be downloaded via the links in the table below.
