Summary

This reports the MAIB’s investigation of the girting and capsize of the mooring launch Asterix while assisting manoeuvring of the small chemical tanker Donizetti at Fawley oil refinery, Southampton UK. The two crew from the launch were rescued the coxswain having been trapped in the upturned wheelhouse for more than an hour. The launch later sank however there was no pollution and although later recovered, the launch was declared a constructive total loss.

Safety Issues:

  • The coxswain’s training did not equip him for the task, and specifically did not equip him to use the gog rope/bridal effectively

  • The launch was not being monitored effectively, and there were weaknesses in the communications between Donizetti and Asterix

  • Launch crews were not sufficiently experienced in the use of the emergency release mechanism and could not activate it effectively
