Support vessel collision with platform

Published on 21/07/23 822 Views

A multi-purpose vessel (MSV) was carrying out a medical evacuation of an injured crewmember to a production platform (helicopters had been grounded due to monsoon conditions). The platform offshore installation manager (OIM) agreed the injured person could be transferred in a basket via a cargo loading crane. The MSV had issues, so it was brought in stern-first under manual control. During this operation, the MSV experienced a strong heave and its helideck struck one or more of the export gas-lift risers, causing a high-pressure release. An explosion and intense fire followed. The fire escalated rapidly, and the platform was abandoned. Within 2 hours, the production platform had collapsed into the sea. Adjacent platforms were severely damaged by heat radiation; the MSV also caught fire.

Ask yourself and your crew:

  • How can something like this happen here (e.g. on our site)?
  • What safety measures (i.e. procedures, controls/barriers) do we have in place to mitigate the risk?
  • How do we know the risk controls/barriers are working?
  • What improvements or changes should we make to the procedures, controls/barriers or the way we work?
