We read about very interesting heavy lift catamaran named VB 10000. The VB 10,000 consists of two 240′ tall lift gantries joined to twin 300′ by 72′ barges to form a catamaran. The gantries are connected to the barges by patented articulated pins which decouple barge motion from the gantries. The vessel is equipped with a Class 3 DP system consisting of four 1,000 HP thrusters in each barge which enable it to maneuver on site and hold station in any water depth over 35 feet. The VB 10,000’s four 2,000-ton heavy lift blocks are paired with custom-engineered 400-ton hydraulic winches which may be operated independently or in a synchronized manner.
You can watch videos below to see how it works.
