Described is a device for lifting an object from a deck of a vessel subject to movements in a heave direction. The device comprises a support surface for the object provided at a first height in the heave direction relative to the deck. A lifting crane is configured to take up the object from the support surface at a lifting point thereof at a lifting speed. An actuator system is configured to lower the support surface relative to the deck at the instant in time at which the object is lifted from the surface to a second height in the heave direction at a lowering speed. A method using the device is also described.

A vessel is disclosed having a body portion that is at least partially suspended above at least one left moveable hull and at least one right moveable hull, each hull being moveable with respect to the body portion. At least one sensor is arranged to sense at least one operational parameter of the vessel. The roll attitude of the body portion is adjustable and controlled during operation in response to the at least one operational parameter to ensure that the sum of the gravitational force and the centrifugal force acting on the vessel during a turn has a line of action that is substantially perpendicular to a deck of the vessel, i.e. that the vessel executes a coordinated turn.

Method and device (1) for lifting loads (7). An arm (2) that is the load or that supports a load (7) is pivotably connected to a reference. The load results in a torque. At least a part of the counter-torque to result in a system supporting the load is provided by a gas or hydro-pneumatic spring (60).

The present invention relates to a wind turbine comprising a nacelle (1) installed on a tower (2) supported by a floating support. The nacelle is articulated with respect to the tower in a vertical plane, and it comprises means (12, 16) for correcting the nacelle tilt, means for automatically adjusting the correction means in accordance with sensors detecting the correction values, the adjustment means being synchronous with the movements of the floating support. Figure 4 to be published.

A gimbal (200) has an intermediate plate (202), a first plate (204) offset from the intermediate plate (202) in a first direction, a first bearing (208) having a first rotational axis connected between the intermediate plate (202) and the first plate (204), a second plate (206) offset from the intermediate plate (202) in a second direction opposite the first direction, and a second bearing (210) having a second rotational axis connected between the intermediate plate (202) and the second plate (206).

A platform (1) for the landing of an aircraft on a boat (B), comprising at least one lower base (2) fixed on the boat (B), and at least one upper base (21), fixed on an aircraft landing footboard (3), wherein a plurality of first curved tubular sections (4), parallel one to each other, are welded inside the frame of the lower base (2), while a plurality of second curved tubular sections (5), parallel one to each other and placed orthogonally with respect to said first tubular sections (4), are welded inside the frame of the upper base (21); said tubular sections (4, 5) are bounded together by means of sliding shaped structures, which are driven through actuating and control means.

A vessel has a heave motion compensated carrier to support an object that is to be offloaded by an offloading device of another vessel or offshore structure. The carrier is supported on the hull of the vessel by a heave motion compensating support system. The system includes a hydraulic cylinder, a hydraulic-power unit connected to the rod-side chamber, a medium separator having a hydraulic-side chamber connected to the piston-side chamber of the hydraulic cylinder, and a bank of pressurized gas tanks. The bank includes a high-pressure tank and low-pressure tanks each selectively connectable via a respective gas tank valve to the gas-side chamber of the medium-separator.

Aspects of the disclosure include apparatus for and methods of facilitating transfer of objects using a crane. Disclosed apparatuses include a target tracking device mounted on or near a crane at a first location, and a target located near a landing location for the object. The target tracking device and the target facilitate real time determination of relative motion between the two locations. Methods of using the same are also disclosed.

A rapid water ambulance for transport of patients, comprising a sick bay solidly constrained to a structure of the water ambulance and support apparatus (10) for a stretcher, the support apparatus (10) comprises: a support column (20), a carriage (30) slidable along the column (20) in the direction of the axis (A) thereof, a support plane (11) for a stretcher, borne projectingly by the carriage (30) and solidly constrained thereto, a damped suspension device (33), constrained to the carriage (30) and to the column (20), which supports the support plane (11) at an operating height, wherein the axis (A) of the support column (20) is inclined with respect to the perpendicular direction to a floor (P) plane of the sick bay and lies in a vertical plane parallel to the motion direction of the water ambulance.

Apparatus (100) and method for providing active motion compensation control of an articulated gangway (200) which comprises at least one fixed part fixedly mounted on a sea going vessel, a movable part being movable relative to the fixed part, and at least one actuator for moving the movable part relative to the fixed part. A first position reference device provides position and attitude information (m) of the vessel referenced to earth. A second position reference device provides position and attitude information (y) of the movable part referenced to the gangway. An actuator driver generates an actuator control output in response to a regulator signal (R). An active motion compensation controller device receives the position and attitude information m and y, an operator control input (J), and the velocity information (y{dot over (y)}) of the movable part. A differential kinematic (DiffKin) device compute and outputs a current position (p) and velocity (v) of the gangway endpoint from m and y. An active motion compensation (AMC) device computes and outputs a reference position (pp) and velocity (vv) of the gangway endpoint from J, p and v computed by the DiffKin, An inverse kinematic (Inv) device computes and outputs a position reference () and velocity reference (i) of the gangway endpoint from p and vv computed by the AMC. A regulator (Regulator) device computes and outputs said regulating signal (R) in response to inputs of said a position reference () and velocity reference ({dot over ()}) computed by the AMC.
