London P&I Club Issues Guide to ECDIS Management

The London P&I Club has joined forces with London Offshore Consultants (LOC) to produce a guide to the proper management of ECDIS (Electronic Chart Display and Information System) on board ships.

The driving force behind the publication “Is your ECDIS contributing to safe navigation or introducing risk?” is the increasing number of negative findings recorded by the club during ship inspections that are attributable to the manner in which the introduction of ECDIS on ships is being managed.

Common Failings when Using ECDIS

In the latest issue of its “StopLoss Bulletin”, the London P&I Club notes that the more common failings identified include a lack of ECDIS content in the watch handover checklist, a lack of familiarity on behalf of bridge-watchkeeping officers with the manual position-fixing method, a lack of GPS position cross-checking, a lack of understanding of the safe application of deep-contour, safety-depth, shallow contour and safety contour, and a failure to revise the Safety Management System (SMS) to include ECDIS.

Well-trained Users

The club indicates ECDIS can enhance navigational safety, but it does require well-trained users that ‘are able to apply vital navigation skills such as manual position-fixing and parallel indexing in the ECDIS environment.’

'While the skills of an experienced navigator can be presumed, familiarity with the electronic method of applying the ECDIS equivalent cannot. The importance of type-specific quality training cannot be overstated in ensuring that staff can perform their fundamental navigational tasks. Also, the “at a glance” constantly updated nature of a GPS position, making progress along a planned course line in ECDIS, whilst a useful feature, can encourage the watchkeeping officer to neglect to cross-reference the satellite-derived position with visual and radar fixes.’

Well-structured SMS Policy

‘It has become evident that a strong management-of-change policy at the heart of SMS reduces the likelihood of such issues arising. A well-structured SMS policy and a good-quality, type-specific training programme can help avoid navigational safety shortcomings caused by the introduction of technology which ought to enhance safety.’
