Endeavour Energy appointed Bibby to perform operations in the Renee and Rubie fields located in Blocks 15/27 and 15/28 of the Central North Sea, about 115km east of Aberdeen.

The 60-day agreement involved Bibby's dive support vessel Bibby Sapphire and construction support vessel Olympic Ares, completing the recovery of subsea equipment including crossover structures, umbilicals and protection mattresses.

"Decommissioning work has been a key area of focus for Bibby Offshore for many years and as a result, we have built up a strong track record," managing director Barry Macleod said.

"Production from the Renee and Rubie fields ceased in 2009 and, following a site survey we completed last October, we were contracted to be part of this extensive project.

"UKCS decommissioning costs are forecast to reach in excess of UKP50 billion over the next 35 years.

"Decommissioning operations in particular are specialist by nature in order to ensure that all materials and often complex infrastructure are removed and disposed of safely and responsibly, with minimal environmental impact."

Bibby also successfully completed work for Tullow Oil through in April and May, utilising DSV Bibby Topaz to perform decommissioning operations at the Orwell and Wissey subsea installations, including the tie-ins at the Thames and Horne and Wren platforms, in Block 49/28 of the Southern North Sea.
