The present invention relates to a vessel comprising:-a hull,-a support structure connected to said hull, the support structure configured for supporting the mass, the support structure being constructed to allow the mass to make a back and forth movement relative to said hull along a trajectory between opposite ends of said trajectory,-a damping device configured to dampen the movement of the mass relative to said hull. The present invention also relates to a method for damping the movements of a vessel or of a mass.

A system and method for the deployment of a conduit system to convey fluids from a marine vessel to an offshore rig are provided. In one embodiment, the disclosure provides a conduit connected to a marine vessel, the conduit comprising: a plurality of sections of tubing; a plurality of flexible joints connecting the sections of tubing; and a buoyancy device at least partially surrounding at least one of the sections of tubing and having a density less than the density of seawater.

The invention relates to a loading arrangement for ships comprising 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 means of 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.

A crane includes a base (1, 2), an articulated jib (3, 4) which is supported by the base, as well as hoisting elements (5, 9) which are guided from the base via the jib, such as a hoisting cable. The jib includes jib parts (3, 4) which are rotatably supported with respect to each other and with respect to the base (1, 2), as well as respective jib part drives (10-12) for varying the angular position of jib parts with respect to the base or with respect to another jib part. One of the jib part drives has series-connected linear actuators (11, 12), one of which is connected to one of the jib parts and the other of which is connected to a jib part adjoining the jib part and which linear drives cooperate with each other via a guide (13) on the jib.

A lifting block and a method of using it for supporting a load from a first lifting device or sharing the load between the first lifting device and a second lifting device, particularly for use on a vessel and deep water applications, are disclosed. The lifting block, with at least one sheave, has first and second connection elements associated with it. In one arrangement (single fall) a lifting wire or rope is fed around the sheave and terminated in an end stop which also provides the first connection element. When the first lifting device is operated alone, the end stop rests on the block. When the second connection element, secured to the lifting wire or rope of a second lifting device, is joined to the first connection element the load is snared between the two lifting devices which can then be operated in unison to position the load at a required, deeper position.

A multi purpose hoisting device for use on a floating vessel having a deck, including: a load bearing structure to be mounted on the vessel; a main hoisting mechanism for raising/lowering an object above the deck and including: at least one main hoisting winch; an upper cable pulley block supported by the load bearing structure; a travelling cable pulley block; a main hoisting cable associated with the at least one main hoisting winch and passed over pulleys of the upper cable pulley block and of the travelling pulley block in a multiple fall configuration, such that the travelling cable pulley block is moveable relative to the load bearing structure by using the at least one main hoisting winch; a main hoist heave compensation mechanism associated with the main hoisting cable for damping the effect of sea-state induced motion of the vessel onto an object supported by the main hoisting cable.
摘要:
Disclosed is a device for transporting and transferring containers. Said device is embodied as a floating and automotive object which is equipped with at least one crane. The crane comprises at least one vertical element, a slewing ring, and a boom. The crane is arranged in the area of a transversal axis that extends perpendicular to the longitudinal axis of the object. Furthermore, the crane is disposed laterally offset relative to the longitudinal axis while a deck house encompassing a pilot house is placed laterally next to the crane.
