Dockwise delivers Lucius sparProjects and Operations // June 20, 2013
Boskalis has announced that its subsidiary Dockwise has successfully offloaded the 23,000 tonne Lucius spar for the Lucius deepwater oil and natural gas project in the Gulf of Mexico.
The Lucius truss spar, measuring 184m (605 feet) long and 34m (110 feet) in diameter, was loaded onto the Mighty Servant 1 by means of a skidding on operation at Pori, Finland.
The spar was transported 7,700 nautical miles and discharged at Ingleside, Texas and delivered back to Technip.
The Lucius Development is located in Keathley Canyon Block 875 in the Gulf of Mexico and is operated by Anadarko Petroleum Corporation.
Spars are usually offloaded over the stern of a semi-submersible heavy transport vessel. However, due to the restricted clearance space at Ingleside, an innovative offloading approach was required. The engineering team at Dockwise developed an approach whereby the spar was unloaded over the side necessitating the design and installation of new buoyancy tanks.
The length of the Lucius spar reached the Mighty Servant 1's carrying capacity limit extending nearly 40m over the stern of the vessel. With the commissioning of the Dockwise Vanguard early this year, Dockwise is strategically well positioned to accommodate larger structures in the future.
