These SEPs range in size from small platforms designed for the Gulf of Mexico to large units up to 115 m in length, capable of installing offshore wind turbines and foundations exceeding 800 tonnes. ORCA platforms can be configured for construction support, light drilling, well intervention, well plug and abandonment, coiled tubing operations, wind farm installation, gas compression and accommodation. The first ORCA 2500, customized for the Middle East and North Africa, was delivered to a Qatari rig operator in February 2016. An ORCA 3500 is currently under construction by

The liftboat began listing to port and capsized in about 35 feet of water after workers extended one of the cranes. NTSB report blamed the accident on inadequate preload procedures that failed to account for shifting and loading the crane.
174:(NTSB) determined that the probable cause of the accident was an industry failure of not providing liftboat operators with enough information about composition of the seafloor. The port leg of the liftboat became unstable, leading to collapse, but it remains unclear whether the sea floor washed away, the leg settled quickly in a "punch-through", or the edge of the nearest canhole collapsed.

As of 2018, the company operates 30 liftboats that service the shallow water oil and gas industry in the Gulf of Mexico from their liftboat dock in Houma, Louisiana.

Liftboats were initially confined to the U.S. Gulf of Mexico to operate on oil and gas well platforms. However starting in the early 2000s, U.S. liftboats were contracted to work in international markets including Brazil, Nigeria, the United
