game pulls oil rigs from the deep.
The US$100 million heavy lifting ship ‘VB 10,000’ is used to pull oil rigs and other wrecks off the sea floor.
Each gantry measures 240-feet tall and weighs 3,400 tons—or about as much as the Ben Franklin Bridge in Pennsylvania. The barges both measure 300 feet by 72 feet and each is powered by a quartet of 1,000HP thrusters which also allow it to remain stationary over the job site. And to prevent the motion of the ocean from affecting the the lift, the VB 10,000 utilizes a set of articulated pins to connect the gantries to the barges. To perform the actual lift, four 2000-ton lifting blocks are attached to the oil rig deck by divers, who also cut off the rig’s legs, and are then pulled to the surface by the vessel’s quad 400-ton winches and deposited on the back of a waiting barge for transport back to port.
