Tahiti Spar

Facts & Figures

Client: Technip Offshore Finland Oy
From: Pori, Finland
To: Corpus Christi, Texas, USA

Dockwise has once again shifted the bounderies in realizing the inconceivable by delivering the 24787 mton CVX Tahiti Spar, which happens to be the largest spar buoy ever to have been transported in one piece. The Heavy Transport Vessel Mighty Servant 1 was used for the transport from Pori, Finland to Corpus Christi, USA on June 12th 2007.

Dockwise was awarded the contract for the sea transportation of this spar buoy in December 2004. Engineering challenges of this transport, categorized by Dockwise and Technip as high risk. The size of the buoy dictated the unique use of specially designed side tanks ( “camel” tanks) as well as an extra buoyancy tank in order to cope with minimized draught and to guarantee sufficient stability during the float off operation.

After a record breaking skid on operation (only 12 hours!) the vessel made a voyage of approximately three weeks, which was only delayed by 3 ∏ hours to heroically pick up shipwrecked survivors in the middle of the Atlantic Ocean. With an average speed of 12,6 knots the Mighty Servant 1 arrived at the GMF yard in Corpus Christi, where the unit will be completed. Before the Tahiti Spar transport, Dockwise has successfully transported 12 spar buoys, which were all built in Finland.
