Safety Alert: Vessels in convoy, awareness of pilot embarkation/disembarkation - Shared by Dublin Port

Published: Wednesday, December 16, 2020 - 15:59

Early Information Sharing is a PSS priority; aimed at proactively preventing incidents.  Safety Alerts are good opportunities for members to review/modify existing safety control measures and are a leading indicator of a positive safety culture.

This Safety Alert has been shared by one of our members to raise awareness of the navigational risks associated with proximity of vessels traveling in convoy and awareness of pilot embarkation/disembarkation operations.

An outbound tanker, under pilotage, proceeding to the pilot boarding grounds for pilot disembarkation was being closely followed by an outbound RORO vessel at a distance astern of 0.5 nm. At the time of pilot transfer and having communicated with VTS, the tanker reduced speed to 8 knots while the RORO vessel astern maintained a speed of 13.3knots therefore closing on the tanker conducting the pilot transfer. Shortly after the pilot transfer the RORO vessel overtook the tanker in the traffic separation scheme with a CPA of 0.2nm

The safe speed of a vessel should be adjusted to take account of the traffic density and the likely reduction in speed to embark/disembark a pilot safely. Masters should also exercise good seamanship in maintaining situational awareness with regard to the risk elements of pilot transfer and the associated manoeuvres of vessels engaged in pilot transfer.
