A newly-developed N. Sea oil-gas platform-building tool which will be used to build the Culzean wellhead platform for Maersk has been successfully tested in Holland.
During its first commercial application, the newly developed CAPE Holland Vibro Lifting Tool (VLT) successfully installed four piles in up to 90m water depth.
This installation is part of the pre-piling project for the Culzean Wellhead Platform jacket which will be installed next year.
The vibro-hammer was used as a stabbing tool to install all four piles in one sequence to stable depth through a template without any tool change. Negating the need for a tool change meant it was possible to install all four piles in just one 12 hour shift to the predicted penetration depth – resulting in significant time savings
Vibro-piling specialist CAPE Holland developed the vibro-hammers for offshore purposes and has been leading the way in using multiple linked vibro-hammers in both offshore wind and oil and gas industries.
The latest development for reducing the cost of installation and noise emissions has resulted in the Vibro Lifting Tool™ (VLT), a Lloyd’s Register certified lifting appliance which can be configured with an upending option.
This can significantly save on the installation time by reducing the number of handling operations. The VLT is able to pick up a stored pile (up to 1600t), upend it to a vertical position, lift it to the correct position and drive it down (correcting verticality while driving if necessary) in one single handling operation without the need of a gripper or seabed installation frame.
Founded in 2002 as a family business with five generations of experience in the areas of construction, foundation and piling equipment, CAPE Holland was acquired by the Buckinghamshire-based FoundOcean Group – which operates a support based in Livingston, West Lothian – for its ‘go-faster’ offshore piling cement.
The award comes as Hercules Offshore Inc, the provider of the new-build jack-up rig for the Culzean development, begins a recruitment drive in Aberdeen as it establishes a permanent UK presence to support the Culzean project and pursue other market opportunities. This inward investment is expected to create up to 100 offshore and 20 onshore jobs.
Martin Pedersen, Managing Director, Maersk Oil UK, said, “The Culzean project continues to progress well. This award has been made on schedule and three weeks after steel cutting began on the heavy duty jack-up rig which will commence drilling in Q2 2016, subject to final approvals.”
