Marine Operations: 500m Safety Zone Learning Resource Launched

Energy Transition Group
20 Apr 2017

Step Change in Safety and the Marine Safety Forum have worked together to create the new Joined-up Thinking (JuT) pack.  The film has been created by compiling several incidents which have occurred in the North Sea where vessels have collided or nearly collided with offshore installations.

Most of these incidents involve vessels that had been invited into the area around the platform –  not errant vessels that had drifted in. The ‘500m safety zone’ surrounds all installations, and the OIM or a delegate is responsible for all marine operations in that zone. All vessels must be invited to enter.

Having a ‘marine responsible person’ communicating with, and monitoring, the movements of the vessels within this zone is good practice in the prevention of collisions. The JuT safety pack has several tools to help manage risk including:

  • a document which outlines the good practice involved when vessels work within the zone including; safe approach, pre-entry checks, working alongside and exiting
  • a poster
  • a short Joined-up Thinking video
  • bulletin and speaker notes

The packs can be downloaded from or
