Cable Handling
Traversing Spoolers
Deck-mounted traversing spooler systems for underdeck carousels — rack-and-pinion traverse, integrated guide chute, VFD electric drive synchronised with the carousel PLC.
Deck-mounted traversing spooler systems for underdeck carousels — rack-and-pinion traverse, integrated guide chute, VFD electric drive synchronised with the carousel PLC.
Deck-mounted traversing spooler systems engineered to feed cable into underdeck carousels — controlled, repeatable lay-pattern across the basket with full PLC integration to the carousel drive.
Each spooler comprises a deck foundation, a rack-and-pinion traverse carriage, and a product guide chute for controlled cable laying into the carousel basket. The spooler control is integrated with the carousel PLC so traverse position, carousel rotation and product feed remain synchronised in real time. The chute can absorb slack during emergencies or when operations stop, protecting the cable and the lay pattern.
Two traversing spoolers, one per underdeck carousel — design, supply and integration with carousel PLC
Engineering, fabrication, FAT and integration of two traversing spooler systems for an underdeck carousel package. Each spooler is mounted on a bolted-to-deck rail foundation with a rack-and-pinion carriage that traverses 5,700 mm across the hatch opening. The integrated guide chute (with LUC rollers) carries the product through the controlled bend into the carousel basket; chute geometry is sized to absorb slack during emergencies or stoppages. The traversing gearmotor is driven by a VFD electrically integrated with the carousel PLC — traverse position is commanded directly from carousel rotation, eliminating operator hand-off and ensuring a repeatable lay pattern.
Engineering, fabrication, FAT and offshore commissioning — all under one roof.
