CrowleY tugs tow oil platform

Crowley Maritime’s Ocean-class tugs, the Ocean Wind and Ocean Wave, recently towed the Lucius spar, a 605’x110′ floating oil platform, from Corpus Christi, Texas, to Keathley Canyon Block 875 in the U.S. Gulf about 300 miles offshore, for Anadarko Petroleum. Crowley tugs Pilot and Warrior, towing heavy-lift-series barges 455-5 and 455-9, followed the spar with 20,000 tons of dry ballast materials to help lower Lucius into the water during installation. The project continued with transport of the rig’s sub-cellar deck, which is the lower of the two decks of the spar’s topside structure. It was transported aboard Crowley’s Marty J, the first of Crowley’s eight 400’x105′ high-deck-strength barges, and towed by the Ocean Sun, the third Ocean-class tug on the job. During the first stage of work, the nearshore phase, the Ocean Wind and OceanWave provided assistance by towing Lucius away from Corpus Christi. In the offshore phase, the Ocean Wind and Ocean Wave maintained their positions and towed the Lucius to its final location in the deepwater Gulf. In the final positioning phase, the three Ocean-class tugs remained on site in a star pattern to provide support as the spar was connected to its moorings and made storm safe in 7,100′ of water. The final phase will involve the towing of the Lucius’ 9,000-ton topside, loaded on Crowley’s 400’x130′ barge Julie B, from Corpus Christi to the spar’s position offshore.
