Australia’s Transport Safety Board has released its report into the lost of containers from the containership Pacific Adventurer, the subsequent holing of the hull and subsequent pollution.
The ATSB investigation found that the most plausible explanation for Pacific
Adventurer’s severe, and at times violent, rolling motions was synchronous rolling, as a result of the ship’s natural roll period matching that of the encounter period of the waves experienced.
While the master took action to avoid the rolling, in accordance with the guidance in the ship’s safety management system, this action was not sufficient. The option of altering the ship’s stability by adjusting the seawater ballast in its tanks, and therefore its natural roll period, as the ship made its way up the Queensland coast, was not considered.
Much of the ship’s fixed and loose lashing equipment was in a poor condition.
