An arrangement for the transfer of a passenger and/or freight unit (container 16) to and from a rig (10) especially to and from a vessel (15) which is freely moveable on the surface of the sea in step with wave movements. Corresponding, cooperating gripping and holding means (32, 33) are arranged on said unit (16) or in connection with the hoisting and positioning device which is connected to the rig or the installation. The gripping and holding means (33) of the hoisting and positioning device are moveable in controlled paths of movement vertically and horizontally and preferably also rotatably mounted about a common vertical axis, via a support means (37) in a support platform (27) which is separately adjustable at different levels between the deck (13) of the rig (10) and the deck (15a) of the vessel, by means of a hoisting device (17) placed on the deck of the rig or the installation. The support platform (27) is in addition kept in place in a particular horizontal position relative to the rig means of guide or tensioning means (30, 31) connected to the rig at a level below the hoisting device. The arrangement may be used to launch or recover life saving equipment to or from the sea. <IMAGE> |
