The present application provides a launching arrangement for a lifeboat from an offshore installation. The launching arrangement may include a garage for the lifeboat, a gate of the garage that can be opened by gravity, wherein the lifeboat can be launched either as a free fall lifeboat or by a fall of a lifeboat winch in case of an emergency situation and while a power supply is off, and wherein the garage is equipped with the gate with a wire rope winch, a lower hydraulic cylinder, and an upper hydraulic cylinder; and the gate of the garage opens by gravity by simultaneous operation of a wire rope winch of the gate and the lower hydraulic cylinder and the upper hydraulic cylinder, both hydraulic cylinders working as a closed hydraulic system; and the lower hydraulic cylinder and the upper hydraulic cylinder including piston rods.

A handling apparatus (10) for supporting and deploying an object (12), such as a marine craft, comprises a support frame (18) and a cradle (20) upon which the object (12) to be deployed is disposed. A retaining flap (24) forms a first portion of the cradle (20) and is coupled to a deployment ramp (26) which forms a second portion of the cradle (20), the retaining flap (24) being movable between a first position which retains the object (12) on the cradle (20) and a second position in which the object (12) is released for movement relative to the cradle (20). The handling apparatus (10) is movable from a first, storage, position to a second, deployment, position in which the object (12) can be deployed.

A portable crane formed of composite members. A composite mast is coupled to a composite boom. A boom end housing removably couples at a top of the mast and includes an enclosure. A first end of the boom couples within the boom end housing. A boom pivot couples to the boom end housing and couples the boom to the mast. An angle adjuster releasably secures the boom at a desired angle relative to the mast. In implementations an end cap is included at a second end of the boom, coupled to a sheave with a pin, the end cap covering a terminal end of a second end of the boom and extending along both sides of a slot in an upper surface of the second end and along a portion of a first side of the second end and along a portion of a second side of the second end.
