Borgland Dolphin


What happened in P&A:
The point load on the boat deck was higher than allowed and 4 x 1m2 steal plates was needed under each funnel.

The Trees also need to be cleaned for marine growth as soon as they are onshore. If the marine growth are left it will start rotting.

What Was Planned

Land the Horizontal Christmas Tree (HXT or XMT) on the boat and transport them onshore.

What Was Learned

Spreading plates needed.

Cleaning required as soon as it arrives onshore. It is not possible to do any effective cleaning on the rig.
