Abstract: A subsea payload such as an AUV (autonomous underwater vehicle) or an AUV garage is lifted from an underwater location by flying a latch unit through the water to the payload. The latch unit carries a lift line toward the payload. The latch unit is then attached to the payload and the payload is lifted using tension applied through the lift line via the latch unit. The latch unit can also be used on a lift line to lower a payload and then to release the payload at an underwater location. The lift line is supported by a heave-compensating winch on a surface vessel that effects z-axis movement of the latch unit. The winch maintains tension on the lift line to prevent the lift line falling on the payload. Movement of the latch unit on x- and y-axes is effected by on-board thrusters.

Abstract: The present invention is typically embodied to exert active control of two same-shipboard cranes performing joint lifting of a payload. Sensory signals indicative of ship motion, and of luff angle and hoist line length of both cranes, are transmitted to a computer. The sensory signals are processed by the computer using a ship motion cancellation algorithm, which solves for values of the respective luff angles and hoist line lengths of both cranes, such values achieving static equilibrium (e.g., zero motion horizontally, vertically, and rotationally in the same vertical geometric plane) of the suspended payload. Inverse kinematic control signals in accordance with the mathematical (e.g., minimum norm) solutions are transmitted by the computer to respective luff angle actuators and hoist line length actuators of both cranes so that the suspended payload tends toward steadiness. Inventive control thus acts on a continual basis to significantly reduce pendulation during the two-crane lifting operation.

For this purpose, the transfer element is attached to the free end of the support arm, or is configured such that it may be connected to the free end of the support arm.

Abstract: A heave or motion compensation system (100) is employed on the crane (20) to compensate for the heave being experienced by a ship (22) on which the crane is mounted. The heave compensation system includes a motion reference unit (102) mounted on a distal end portion of crane arm (36) to measure the movement (acceleration) thereat. This information is transmitted to a programmable logic control processor (104) to control the operation of a winch (50) carried by the crane thereby to pay out or reel in the load line (32) of the crane. The distal end of the load line is connectable to a load being lowered or lifted by the crane.

Abstract: The instant invention is directed to a active-over-passive coordinated motion winch designed to be used in combination with a class of existing offshore lifting systems such as A-Frames, booms or cranes to minimize the relative movement between a payload position and a destination position occurring commonly in offshore operations.

Abstract: A method and system are provided for reducing sea state induced vertical motion of a shipboard crane's load. Sea state induced vertical velocity of the crane's suspended load is determined as a function of: i) the horizontal radial distance the load extends from the crane's axis of rotation, and ii) motion of the ship at the crane's axis of rotation. The load is then moved vertically at a speed that is defined as being equal to the vertical velocity in a direction that is opposite that of the vertical velocity.
