BP Exploration Operating Company Ltd. contracted Heerema Marine Contractors Nederland BV (HMC) for the decommissioning, removal and recycling and disposal of the North West Hutton platform, the largest steel jacket platform to be removed from the North Sea so far. In 2008 the topsides were successfully removed.

The project involved th following campaigns:

  • In 2008, the topsides were removed by SSCV Hermod and the structures transported on various cargo barges to the Able recycling yard in Teesside. Load-in of the structures was performed by land cranes and trailers. Total weight of the structures was appr. 20,000 tonnes.
  • In the 2008 campaign, three major activities were performed simultaneously from the Hermod:

    • the hook down of the modules (by PSN, RBG and HMC) 
    • the removal of the modules (by HMC)
    • part of the preparatory subsea work for the jacket (by ROV's and subsea cutting tools)

  • In 2009, the jacket was successfully removed and cut into several major and minor pieces by SSCV Hermod. All structures were transported by various HMC cargo barges to the Able recycling yard in Teesside. Load-in of the structures was done by land cranes and trailers. Total weight of the structures is approx. 9,000 tonnes.
