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.
