Rickmers Dubai, Kingston & Walcon Wizard Accident Investigation Report

Published 23 October 2014

The safety issues identified are:

  • Rickmers Dubai’s OOW was alone on the bridge and he did not see Walcon Wizard. He did not keep a visual lookout or monitor the radar. Instead, he relied solely on AIS information for collision avoidance, which neither Kingston nor Walcon Wizard were transmitting.
  • The OOW was relatively inactive throughout his watch and did not take note of safety broadcasts issued by Dover Coastguard which included information regarding the position and movement of Kingston and its tow.
  • The towline secured to the winch on board Kingston could not be released from the wheelhouse, highlighting ambiguities in the regulatory requirements for the release of towlines.

Bayliner Capri Accident Investigation Report

Published 16 October 2014

The safety issues identified are:

  • The men were not sufficiently experienced for the deteriorating weather conditions encountered, and had probably not studied the forecast.
  • The boat had a low freeboard at its stern making it vulnerable to swamping when its propeller became fouled.
  • The boat had no VHF radio, no distress flares and apart from the men’s mobile phones, there was no means of raising the alarm as the situation deteriorated.
  • The men were not wearing lifejackets or thermal flotation suits and did not have personal locator beacons. Only one of the men wore a buoyancy aid, which, unlike a lifejacket, was not able to turn him face-up and keep his mouth clear once he entered the water.
