The Derrick Barge 50 completed the installation of a drilling and production platform for the U. S. Gulf of Mexico (GoM) continental shelf that included the heavy lift of a 3,250-ton jacket in the GoM, McDermott International Inc. said in a press release. This lift establishes the record for the largest jacket lifted by the vessel to date.

“The project specified that the jacket be lifted, not launched and our heavy-lift vessel fit the criteria, providing the flexibility required to install a jacket of this magnitude and its corresponding deck,” said Scott Munro, vice president, Americas/Europe/Africa for McDermott.

The six-pile platform was lifted by the Derrick Barge 50 in tie-back mode over the stern of the vessel in waters 119 m (391 ft) deep over an existing well site. Piles were driven to a designed penetration of 131 m (430 ft) and a 2,300-ton drilling and production deck was then installed on the jacket.
