Rever Offshore completes subsea decommissioning ops on Dunlin

Subsea services provider Rever Offshore has completed subsea infrastructure decommissioning of the Greater Dunlin Area in the North Sea for Fairfield Energy.

Rever said on Tuesday that this complex project utilized saturation DSVs Rever Sapphire and Rever Polaris along with the CSV Normand Clipper.

The workscope involved multiple campaigns comprising of preparation, removals of subsea infrastructure, and final surveys, along with the management of all recovered waste for processing and safe disposal.

The project, which began in January 2018, was completed in a two-year campaign utilizing nearly 300 vessel days. Termination of production from the Greater Dunlin Area was announced in May 2015, and cessation of production was on June 15, 2015.

Barry Macleod, Rever Offshore CEO, said: “This project is extremely significant for Rever Offshore, being one of the largest scale decommissioning projects undertaken by the company and the first completion of a full engineering, preparation, removal, and disposal contract.”

It is worth reminding that Fairfield initially awarded a contract for the subsea infrastructure decommissioning of the Greater Dunlin Area to Bibby Offshore in February 2018. Later that year, Fara Holdco Limited, the owner of the Bibby Offshore group of companies, decided to merge Bibby with Rever Offshore.

Fairfield received an approval of its decommissioning program for the Dunlin Alpha topsides from the UK authorities in May 2019.
