Wacker Quacker 1 and Cleopatra Combined Accident Investigation Report

Published 17 December 2014

The safety issues identified are:

  • Wacker Quacker 1 sank because it did not contain sufficient buoyant material to remain afloat in the flooded condition.
  • The converted World War 2 amphibious passenger vehicles in Liverpool and London had been allowed to operate for over a decade without having met the UK’s mandated buoyancy standard.
  • When the London based operators inserted the required volume of buoyancy foam, it introduced the circumstances that led to the fire on board Cleopatra.
  • The confined nature of the amphibious vehicles made it extremely difficult for the crews to control and assist the passengers.
  • It was extremely fortunate that lives were not lost, as in both cases the passengers and crew had to act on instinct and evacuate into the water under their own initiative, many without personal floatation devices.

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.
