Drillship BOP Heavy Lift

Owner: Transocean
Location: Offshore
Project Duration: 08/2011

In August of 2011, the derrick barge Wotan loaded out a 350 ton Blow Out Preventer (BOP), to Transocean’s Drill Ship, Deepwater Navigator. This lift was complex due to the delicate nature of the BOP and the narrow clearances of the drillship. The BOP was designed to be installed in two sections and because of the ship’s operating draft, the lifts were required to be made at an offshore location.
