Following a surf riding and broaching incident and subsequent collision by an experienced vessel operator, QinetiQ have been undertaking extensive investigations into the risk mitigation and safety management of pilotage operations. This presentation looks to discuss the risks presented during pilotage services, and provide a critical review of vessel design and service delivery approaches to understand the potential risk mitigations and management of pilot boat safety.

The vulnerability of GNSS in shore-based use is definitely different and to be regarded as much more risky than on the high seas.

The Coast Guard Office of Investigations and Analysis has released Marine Safety Alert 05-21, to notify mariners to a potentially dangerous situation involving corrosion of the turntable pin on accommodation ladders.

Exemplary manoeuvre: The pilot should always walk on the side of the pilot boat facing away from the vessel. This prevents the pilot from being trapped between the two vessels in the event of a fall into the water.

Since 2022, there is a solution in Germany that helps pilots to report defects in pilot ladders or pilot transfer arrangements quickly and easily. The apps are available for Android & iOS.
