August 6, 2009 – Successful Finalization of the CPOC Project

Dockwise successfully performed the USD 33 million complete transport and float-over installation of 19,000 tonne (20,944 s.ton) MDPP offshore production platform for CPOC located at the JDA Block B-17, C-19 and B-17-01.

Dockwise was the main contractor for CPOC, the operator. Since the contract was awarded in August 2007, Dockwise's multi-disciplined project team was dedicated to the execution of this complete transportation and installation float-over project under the direction of the company's Senior Project Manager, Aart van den Hoonaard.

Preparation for the project included custom-design and fabrication of Leg Mating Units (LMUs) and Deck Support Units (DSUs), mating and mooring analyses and synchronization of transport, structural, marine and installation engineering expertise.

After outfitting the Dockwise vessel, Black Marlin, with grillage and skidbeams, as well as additional steelworks the giant MDPP module was skidded on board the vessel at the Sembawang Yard In Singapore. After the completion of the load-out and sea-fastenings, the vessel departed for offshore location where the float-over installation took place.

"The float-over operation itself was carried out in environmental conditions that were close to those calculated as the limit for a safe operation; Wind 15 - 20 knots and decreasing after 3 pm, sea and swell approximately 1.0 m significant but with a short period that hardly caused any motions on the Black Marlin" says Herman van Raaphorst, Dockwise Director of Projects.
