Offline Activity Crane - Offshore

King-post or slew-bearing cranes fixed to a deck pedestal that rotate 360 degrees to handle cargo and equipment across the rig. They form the primary offline lifting platform on most offshore units.

Cranes positioned to lift loads between the rig deck and a supply or workboat alongside. They are rated for dynamic loading and offlead/sidelead conditions created by vessel motion in a seaway.

Higher-capacity cranes or crane configurations dedicated to moving the BOP stack, lower marine riser package, and associated components during offline maintenance. They are sized for the heavy, concentrated loads these assemblies impose.

Cranes used to transfer riser joints, casing, and drill pipe between storage racks, the catwalk, and the deck. They support pipe staging so that tubulars are prepared without interrupting drill-floor activity.

Smaller-capacity cranes serving general deck logistics, container moves, and equipment handling away from the drilling package. They handle routine lifts that would otherwise occupy the main crane.

Articulated-boom cranes whose jointed boom folds for compact stowage and precise load placement in confined deck areas. They suit tasks requiring reach over obstructions or close positioning.

Cranes fitted with active or passive heave compensation to reduce dynamic load swings when lifting to or from a moving vessel or subsea. Compensation limits snatch loads and improves lift safety in higher sea states.
