摘要:
A gangway apparatus (10) for transfer between vessels or between a vessel (38) and a fixed structure such as an offshore construction or a quay is disclosed. The gangway apparatus (10) includes a gangway component (16) which is preferably buoyant and may be inflatable. The gangway component (16) is mounted on a skate or bogie and traverses a fixedly mounted runway (14) . The runway (14) may be inclined. Control means are provided for controlling the motion of the gangway component on the runway. These may include biasing means such as a counterweight. The apparatus is preferably mounted in a shipping container such as a 40' ISO container.

The present invention provides an apparatus and method of a dock system for launch and recovery of a stowed boat, which is capable of launching and recovering the boat during navigation of a marine vessel at a high headway speed. The launch and recovery apparatus has a stern dock (2) for accommodating the boat (10) therein. The apparatus launches the boat outboard through a stern opening and recovers the boat from the outboard area by entry of the boat into the dock. The apparatus is provided with a conduit device (11) so that seawater surrounding the vessel is drawn through an intake port (12) and is delivered to the dock through an outlet port (13). In the dock, a backward water stream is generated, which is to be discharged outboard through the stern opening.

The present invention relates to a bow visor (1) for a boat hull (2). Such a solution is thus characterized in that the boat hull (2) has a pointed fore (3), whereby the bow visor (1) constitutes a part of a forebody such that a joint (4) of a freeboard (5) of the boat resides more or less parallel with a centre plane of the boat. This joint further divides a surface between a bottom (6) and the freeboard, a bilge (7), so that the part of the bilge that is located closer to the fore coincides with a lower edge (8) of the bow visor, and the joint then continues towards a stempost along a line where the bilge meets the bottom.
摘要:
A floating vessel is stabilized against a stationary object, for example a mast of an offshore wind turbine. The vessel comprises a hull, a motor for the propulsion of the vessel, a buffer body, which protrudes with respect to the hull, as well as at least one engagement arm. The engagement arm is at one end provided with an engagement member for engaging on the stationary object. First, the buffer body of the vessel is pushed against the stationary object by means of the motor. The buffer body is hereby substantially stabilized against the stationary object. Next, the engagement body engages on the stationary object while the buffer body and the stationary object remain mutually stabilized by the pushing. After this, the engagement arm is subjected to tensile load while the stationary object is engaged by the engagement member.
摘要:
A method and arrangement for operating a ship ramp driven by an electric motor between an upper end position and a lower end position, the arrangement comprising means (40) for reducing the maximum torque of the at least one electric motor (30) when the ramp (10) is in proximity to an end position of the ramp, means (40) for determining the position of the ramp (10) on the basis of the number of rotations performed by the at least one electric motor (30), or a quantity indicative thereof, or on the basis of the elapsed time and the velocity of the ramp, and means (40) for allowing the reduction of the maximum torque of the at least one electric motor (30) only when the determined position of the ramp (10) is within a zone defined by predetermined limits.
摘要:
Device for disembarkation on a marine structure (1) for landing a craft (10) that can be conveyed on the surface of water (3), comprising interacting landing devices (2, 17) arranged to the marine structure (1) and craft (10) respectively. The landing devices comprise a principally vertically elongated part (2) and a means of contact (17) respectively, the means of contact (17) is intended to partially surround part of the elongated part (2).
摘要:
The invention relates to a hull element (7), which is attached to the stern (1) or hull bottom (1b) by means of a hinge means (6, 6a) and enables active and passive trimming of the watercraft (1a), and at the same time also supports a watercraft lift (2) or watercraft steps (11) by means of the connection (8) or a connecting cylinder (18). The platform (3) or watercraft steps (11) can be activated by means of the acting cylinder (17b) and the connection (8) or connecting cylinder (18) on the hull element (7). If the watercraft lift (2) or the watercraft steps (11) are actuated by means of the acting cylinder (17a), the hull element (7) folds away such that the lift H of the watercraft lift (2) or the lift HT of the watercraft steps (11) is not impaired or limited.
