A cargo container storage and retrieval system and method. One embodiment of a system according to the present invention includes a vessel having cargo hold with a plurality of bulkheads disposed along a width of the cargo hold to define a plurality of adjacent cells along a length of the cargo hold. The cargo hold is also equipped with a plurality of tiers along a depth of the cargo hold. The vessel also includes a deck having a plurality of hatch openings that are used to gain access to the cargo hold. In addition, the vessel includes a storage and retrieval system having a plurality of sets of parallel spaced tracks and a plurality of chassis seats disposed within each set of parallel space tracks. Each track of each set of parallel spaced tracks is mounted to a surface of a bulkhead of opposing bulkheads so that one set of parallel space tracks is disposed within each cell along the length of the cargo hold and so that a plurality of sets of parallel spaced tracks are disposed within each tier of the cargo. Each chassis seat has corresponding wheels that move along a corresponding set of parallel spaced tracks to provide a plurality of chassis seat along the width of the cargo hold for each set of parallel spaced tracks within each tier. Each chassis seat is equipped to hold a standardized cargo container.

A method and apparatus for the installation or removal of large multi-ton prefabricated deck packages includes the use of usually two barges defining a base that can support a large multi-ton load. A variable dimensional truss assembly is supported by the barge and forms a load transfer interface between the barge and deck package. Slings are suspended from a compression frame portion at the boom end portions of the truss assembly. The slings form attachments between the compression frame and the deck package at the upper elevational positions on the deck package. Tensile connections form attachments between the deck package and barge at a lower elevational position. The variable dimension truss includes at least one member of variable length, in the preferred embodiment being a winch powered cable that can be extended and retracted by winding and unwinding the winch.

A transfer apparatus for transferring objects from a first location to a second location includes a transfer device adapted to be coupled to a lifting device. The transfer device comprises an outer structure which defines an inner space in which an object to be transferred may be located and securing device is provided to secure the object to the transfer device during transfer.

A method and apparatus for the transfer of loads from a vessel that moves with heavy seas to a stationary or mobile installation by the use of at least one lifting cable and at least one hoisting mechanism, where the load, in a starting position, stands on a rack on the vessel. The load transfer takes place at an instant when the load has only insignificant kinetic energy, as the gripping mechanism is activated in a controlled manner at the instant to lock the load to the lifting cable. At the same instant the rack collapses and immediately establishes a distance between the load and the vessel, thereby suspending the load on the lifting cable.

A machine for gripping and handling underwater vehicles and the like includes a gripping device provided with a guiding member made integral at its upper end, an articulated member connected with a rod sliding inside a guide attached to a free end of a jib of the crane and with floats capable of maintaining the guiding member raised above the water in a preset position of the rod relative to the guide controlled by a sensor imparting movement to the jibs of the crane in order to maintain the gripping device in vertical position relative to the ship.

The present invention provides an apparatus for launching and recovering a submersible vessel from a ship, and includes a gantry that pivots in an arc extending over and beyond the aft deck of the ship. A lift line passes about a head sheave that pivots from the top of the gantry and threads through a saddle that also pivots from the top of the gantry. The saddle is clamped to the vessel. The lift line is connected to the top of the submersible vessel and passes about a ram tensioner which may be mounted on the deck. After a winch pays out the lift line to lower the vessel into the ocean, the saddle is disconnected from the vessel and the lift line is rethreaded back out of the saddle. A tether provides a communicative link between the ship and the vessel, and may pass about a hanging sheave suspended from the gantry when the vessel is in the ocean. Recovery of the vessel is the reverse of deployment.

A lifting device is provided for rapidly coupling and uncoupling a floating load, such as a boat, when it is set afloat or raised from the water. It includes essentially a hook secured to the load and a coupling element connected by cables to a lifting appliance. The concavity of the hook is turned downwards. Its section is trapezoidal and tapers towards its tip. The coupling element includes two arms whose facing walls are slanted and guide the hook towards the central housing. Springs, disposed laterally in the housing, come to bear against the lateral slanting faces of the hook and prevent it from leaving again.

This invention relates to a boat designed as a self-hoisting unit for the vertical and horizontal transfer of persons and/or equipment from a ship to an offshore platform and vice versa. The boat carries a hollow mast forming a guide for a cable, the upper end of which will be attached to a carrier structure extending outwardly from a platform or ship. The mast is held by shrouds so as to withstand large flexural strains. For compensating sea-swell, the lower end of the cable passes over a damper unit comprising an hydraulic cylinder associated with pulleys of two opposed tackle-blocks. The cable is driven by a winch so that the boat can autonomously hoist itself to the platform deck level, or lower itself down to the sea or onto the deck of a ship. The mast height is sufficient for generating an uprighting torque ensuring horizontal stability of the boat during its ascent and descent. The boat is suitable for carrying a large number of persons, for instance as a lifeboat or for a shuttle service between offshore platforms.

An A-frame has a winch head swingable from a cross-member and between its two arms. A docking member comprises an upper frame depending, by means of hydraulic rams, from the winch head and a lower frame swingable from the upper frame about an axis perpendicular to the axis about which the winch head can swing from the cross-member. Guides for a load-carrying line are provided on the frames.

A method and apparatus are provided for recovering a towed body to onboard a towing ship while the towing ship is underway. A saddle is employed in cooperation with a rudder to engage one end of the towed body and, subsequent to engagement, the saddle means is slid forward to engage the opposite end of the towed body.
