<p>PCT No. PCT/SE97/00657 Sec. 371 Date Oct. 15, 1998 Sec. 102(e) Date Oct. 15, 1998 PCT Filed Apr. 18, 1997 PCT Pub. No. WO97/39940 PCT Pub. Date Oct. 30, 1997A dock, for launching and recovery of a lifeboat, rescue boat or like small boat on a vessel, a floating platform or a fixed installation. The boat (14) is normally stored on the dock. The dock is provided with buoyant elements (1) fixed to a frame (3). The boat (14) is supported in a cradle (2) within the frame (3). On launching and recovery of the boat (14), the dock is lowered to a floating position on the surface of the water. In order to fix the boat (14) to the dock, a locking device (9, 15) is provided. By modifying the configuration and size of the buoyant elements, the dock is given rolling and pitching periods which coincide as closely as possible with those of the boat (14). The dock and the boat (14) will thereby behave in approximately the same manner in the water, which makes it relatively simple to run the boat (14) into the dock even in a very heavy sea. When the boat (14) has been introduced into the dock, it is in contact with the dock at least two points, and the boat (14) and the dock are then fixed to one another by a locking device (9, 15) to form a cohesive unit.</p> |
