GALLIANO — What a Galliano company says is the world’s largest liftboat is now plying the Gulf of Mexico, The Associated Press reported Tuesday.

Montco Offshore christened the Liftboat Robert last month at Port Fourchon. The vessel was built by Gulf Island Fabrication and its marine-construction subsidiary in Houma. It’s owners said the size of the vessel will enable it to house more workers and cut the time needed for dismantling rigs and platforms that have finished exploring for or producing oil.

Liftboats have four legs that allow an open deck to rise above the water.

Typical liftboats measure about 80 feet wide and 130 feet long, with legs that measure up to 250 feet.

The Liftboat Robert, is 135 feet wide and 290 feet long, with 335-foot legs.
