Moon Pool Hatch Covers/Doors

Moonpool hatch covers/doors

PALFINGER delivers moonpools of all types and sizes. Single, double or multiple door designs are specifically adapted for the moonpool lift equipment and can be fully integrated with moonpool bottom doors. Top door structures are designed to support the same load as surrounding deck areas. Door controls can be integrated with the lifting equipment control system and benefit from fail-safe locks which ensure personnel and equipment safety. The moonpool doors are downward-opening types. Each door is operated by hydraulic cylinders, locking cylinders secure the doors in closed position. Service and maintenance access for the cylinders is provided from the moonpool cofferdam.
