Significant time savings have been achieved on piling work for the Culzean Wellhead Platform in the North Sea 240km east of Aberdeen following trials of new equipment by contractor Cape Holland.
The detailed design for the Maersk Oil platform is being undertaken by Ramboll and includes the piled foundations for the structure which is located in 90m of water.
Cape announced this week that it had successfully used a new technique to install four piles for the scheme in one 12 hour shift, which the company has said represents a significant time saving.
Cape use its vibro lift tool (VLT) as a stabbing tool to install all four piles in one sequence without needing to change tools. The company said that this is the first commercial use of the new equipment.
Commenting on the project, Cape CEO Laurens de Neef said: “It [VLT] increases the pile installation rates by optimising crane handling operations with an added advantage of reducing the amount of required equipment on deck.”
