An aquatic support vessel including a storage rack configured to stow one or more modular marine vessels. The aquatic support vessel further includes a gantry crane having a rigid, extendable column configured for lifting one or more of the modular marine vessels out of the storage rack and placing one or more of the modular marine vessels into the storage rack.

Proposed are an OHT vehicle and a method of controlling the operation of the same. More particularly, proposed is a technology in which when a hand unit of an OHT vehicle loads a transfer container and unloads the same to a destination load port, an error between a recess of the transfer container and a positioning pin of the load port caused by the tilt of the transfer container is resolved through position correction of the hand unit, thereby enabling the transfer container to be accurately placed on the load port.

A crane assembly containing a boom for an overhead crane and trolley contains an arm having a first vertical portion and an outer surface, the arm fixed to the crane for upper and lower movement of the arm, and the arm containing a second portion angularly extending from the vertical portion. An outer sleeve surrounds and is fixed to the vertical portion, wherein the outer sleeve is fixed to the trolley and extends about the arm thereby defining a plenum between the outer sleeve and the inner vertical arm. During operation, the arm is adapted to be vertically moved within said outer sleeve. A support beam is fixed to the trolley, and is hingedly connected to the outer sleeve. A drive assembly is connected to the outer sleeve for rotating the boom about the support beam.

A crane may comprise a mast that includes a base end and a top end located opposite the base end, at least one support beam fixedly coupled to the mast adjacent the top end of the mast, a first runway beam fixedly coupled to the at least one support beam, and a second runway beam spaced from the first runway beam. In some embodiments, the first runway beam defines a first end and a second end, and the mast is located closer to the first end than the second end. The crane may also comprise a bridge movably coupled to the first runway beam and the second runway beam, a trolley movably coupled to the bridge, and a hoist coupled to the trolley. In some embodiments, the crane only comprises one mast.
