Standards in Force
SOLAS regulations V/18 and V/19, requires that in order to achieve chart carriage requirements (in terms of SOLAS), the 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 A.817(19), as amended; or resolution MSC.232(82)), depending on the date of their installation.
See also Information on IHO Standards related to ENC and ECDIS for additional information on IHO standards that are relevant to ENC provision and ECDIS carriage requirements.
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 (ENC);
- be maintained so as to be compatible with the latest applicable IHO standards;
- have adequate, independent back-up arrangements in place.
The following ENC and ECDIS related standards apply.
