In the course of developing the publication "Recommendations on usage of ECDIS and preventing incidents" [19] by members of the Oil Companies International Marine Forum (OCIMF), they have identified the importance of sharing information on a malfunction of an ECDIS. The problem was discussed in the forum of the International Maritime Organization (IMO). As a consequence, there was a necessity to modify the IMO’s ECDIS – Guidance for Good Practice. This guidance is intended to assist smooth implementation of ECDIS and its ongoing safe and effective use on board ships. In the new version of this document (second revision), new important terms appear, such as: type approval authority (TAA), type approval certificate (TAC), letter of acceptance (LOA), declaration of conformity (DOC). In this article, the author tries to present the problem and describe the actions taken by the appropriate IMO bodies.

Revision of the IMO’s performance standards for ECDIS. Three versions of performance standards in use

Traditional marine navigation methods are replaced by new solutions that use computers. Electronic Chart Display and Information Systems (ECDIS) are mandatory almost on every vessel [24],[25]. ECDIS not complying with regulations is an existing problem and a hazard for seafarers and the marine environment. But unfortunately, there is a deficit or even lack of procedures for checking whether ECDIS meets related performance standards. Regulatory bodies of the maritime industry are now contemplating how to tackle this blunder [1]. SOLAS regulations V/18 and V/19 [24], requires that in order to achieve chart carriage requirements (in terms of SOLAS Convention), the ECDIS equipment must conform to the relevant IMO performance standards. ECDIS units on board of the ships are required to comply with one of three performance standards (either IMO resolution A.817(19) [18], as amended [19],[20], or resolution MSC.232(82)) [21], or resolution MSC.530(106) [23], depending on the date of their installation. In this article, the author tries to explain the differences in these three documents. Along with technological progress, the equipment becomes more and more advanced and technologically sophisticated. This applies to both hardware, software and databases. ECDIS software developers should use the right tools, including incorporate automated self-tests into their products and shipping companies should employ maintenance strategies to improve ECDIS compliance [1], taking into account that time is running quickly.
