Abstract: An apparatus for restraining an assembly suspended by a structure on an offshore platform or vessel, includes a movable carrier configured for controllable movement on a structure of the platform or vessel. A restraining member is movably connected to the carrier via a joint and the restraining member includes an abutment region for abutment with at least one element of the assembly. An assembly-locking device is provided for selectively and releasably locking at least one element of the assembly to the restraining member. A restraining device for a tensioner assembly which is suspended by a structure on an offshore platform or vessel and extending into a moonpool, includes a pair of restraining apparatuses, arranged on opposite sides of the moonpool and individually movable on respective rails by a traction device in interaction with respective racks.

Abstract: A seafastening apparatus includes a movable frame having an opening configured for receiving and at least partially supporting an equipment unit. A locking device is configured for selective locking and releasing of the equipment unit and hence controlling lateral movements of the equipment unit relative to the apparatus. The locking device includes wires configured for connection to the equipment unit and tensioners configured for controlling the tension in each wire, and a pair of extendible and retractable arms are configured for conveying and guiding at least on of the wires.
