BOP CHAINHOISTS
BOP Chain Hoists are often employed on Jack-ups to move and maintain the BOP Stack beneath thecantilever. Working as a pair, each chain hoist connects to the BOP Lift ring providing tandem lifts of up to200 Tonnes.
Each Hoist is mounted on runwaybeams suspended beneath thedrill floor structure.Travel along each runway beamis via rack and pinion mechanismson each hoist / Beam. The hoist liftingchains are dispensed from a chain bucketby the hoist drive and reeved via idler sprocketsover the lifting block assemblies.
Each hoist can be operated independently, and used for BOPStack Maintenance tasks.
Typical Specification
Safe working load: Up to 100 Te per hoist
Hoist speed: Up to 1.1m/min
Travel speed: Up to 6m/min
Chain safety factor: 5:1
Type of control: Deck mounted or hangingpendant

PRODUCT NAMEHERE
Wire Rope Hoists are sometimesused on jack-ups for handling the BOPStack. These systems are mounted on parallel runwaybeams which span the cantilever.
Trolleys traverse each runway beam via rack andpinion, carrying lifting blocks and reeving arrangements above to suit.The winches are mounted at fixed points on the end of each runwaybeam and reeved around sheaves at the opposite end of each runwaybeam. Spool-geared diverter sheave arrangements may be employedwhere headroom is limited to ensure rope fleet angles are within limitsand rope life is preserved.
The parallel wire rope hoisting arrangements provide tandem lifts of upto 100 Tonnes, using the BOP's lifting arrangement / lift ring
