Abstract
Abstract A method of and apparatus for connecting a material and personnel transfer ramp from an offshore oil structure, or the like, to a floating vessel which comprises a docking pedestal rigidly attached to the deck of a vessel, an attachment assembly which coverably and rotatably mounts onto the pedestal, the attachment assembly being provided with a swivel connection allowing attachment to a ramp mounted on an offshore structure, a line hanging down from the attachment assembly which is readily accessable from the boat, and a winch and associated line which guidably connects the attachment assembly on the ramp to the pedestal attached to the vessel. The limp hang line offers a great latitude of movements and ease of handling for connection in rough sea conditions. The correct method of attaching a free moving vessel to a stiff ramp structure is critical during the docking operation in order to prevent excessive shock loads.
