A method and device to balance a tiltable arm comprising a free extremity and having a pivot point on a mounting structure which is supported by a floating object, by providing the arm with suspension and/or support means for controlling the arm's inclination with respect to the horizon, and by providing said suspension and/or support means with at least one spring, wherein the spring connects to the arm and to said mounting structure, and embodying the spring as a passive spring which is arranged to balance the arm so as to stabilize a position of a free extremity of the arm during movements of the floating object.

A watercraft may include a crane for lifting loads. The crane may include a tower and a boom that is rotatble with respect to the tower. The tower may be positioned inside the outer contour of the watercraft so as to minimize the profile of the watercraft on radar. The watercraft may include a superstructure within which the tower may be disposed. The superstructure may include planar outer walls that are obtuse relative to a horizontal plane. A rotary bearing may be utilized to connect the boom to the tower and permit the boom to rotate relative to the tower. Further, when the boom is in a rest position, a lower edge of the boom may be positioned 10 cm or less above the crane deck.”

A method and structure for mooring seaworthy craft against boat landings is disclosed. The structure comprises a fender (4) with a layer of compressible material having an exposed surface, mounted on the craft. Anchor points (12) are secured at laterally spaced locations on the craft, as are two draw mechanisms (14), one associated with each anchor point (12). A tie (10) is provided for extending from each anchor point (12) to its associated draw mechanism (14), and each mechanism is operable to draw its respective tie from an anchor point around a pylon thereby urging the fender (4) against both pylons. In the mooring process, the craft is first steered to the boat landing to engage the fender (4) against the pylons (6), and the ties (10) are withdrawn from each draw mechanism (14) and taken around one of the pylons. Each tie is then attached to an anchor point (12) on the craft, and the mechanisms (14) are activated to draw the ties (10) around the pylons to urge the fender (4) against them. A control system maintains the required tension in the ties to secure the mooring.

A vessel having at least one hull, a body and a suspension system for supporting at least a portion of the body above the at least one hull is described. The suspension system includes at least one support means, and the vessel further includes at least one gyroscopic stabilizer for attenuating rotation of the body about at least one stabilizing axis.

The invention relates to a loading arrangement for ships including a plurality of bales, in particular packaged garbage round bales that are stacked in a hull and that can be loaded and/or unloaded by a crane and/or a transfer device, preferably with gripper tongs for gripping two bales at once in each case. For the gentle unloading and secure gripping of the bales, according to the invention the bales are stacked in multiple transverse rows (5), in particular dual rows, between which in each case a bale stack (6) is arranged that is oriented in a right angled horizontally twisted manner.
