Surveyors trapped in tank as rating leaves post

摘要

The vessel was en route, with a couple of ship surveyors onboard to perform steel condition assessments. One area of interest was the aft peak ballast tank. This tank was drained to allow the surveyors inside. The stern shaft, which passed through the lower aft peak ballast tank, was rotating throughout and the chief engineer was keen to re-flood the tank as quickly as possible to ensure shaft temperatures did not increase beyond specified limits. It was a tight space and required a lot of wiggling and squeezing through small holes and around bends to get to the furthest reaches of the tank.
