The Marine Safety Forum (MSF) has published Safety Alert 18-20 on Potential Dropped Objects in Frame Pockets. 

What happened?

When preparing a heavy lift to be discharged from an offshore supply vessel to an offshore installation, the vessel’s AB’s were carrying out final checks, which included checks for any potential dropped objects. During these checks, they discovered some debris within the frame pocket. The items were estimated to weigh approximately 1kg.

What went wrong? What were the causes?

Cargo checks onshore failed to spot the items before the lift had been loaded onto the PSV. This was apparently due to the lift frame positioning on the trailer which may have hampered the checks at the gantry.

Debris discovered within frame pocket

What actions were taken? What lessons were learned?

  • The potential dropped objects were removed from the pocket and the lift was safely and successfully discharged to the offshore installation.
  • This alert highlights the importance of final checks on all lifts prior to discharge offshore even though there had been previous checks onshore.

The full MSF safety alert can be found here.

The MSF notes that further information and guidance on the checking of cargo items for potential dropped objects can be found in ‘Best Practice for the Safe Packing & Handling of Cargo to & from Offshore Locations’ available at www.onshoreoffshorecargo.com.
