摘要： A mooring boom (10) for tethering a floating structure (15) to a tethering station (13) comprises first and second rigid elongate members (11,14) one slidably mounted on the other whereby the boom (10) is of variable length. One end (11A) of the boom (10) is secured to tethering station (13) whilst the other end (14A) of boom (10) is connected to floating structure (15). The boom (10) includes a pneumatic ram arrangement (18) formed by at least one piston and cylinder unit (19) arranged resiliently to resist sliding movement between the members (11,14) in at least one direction.

摘要： A marine heave compensating device comprises a hydraulic piston and cylinder unit (15, 16) with its cylinder (15) secured to a support (10,11). The piston is connected via a piston rod (16) to a cross-head (17) on which a first set of pulleys (18) are rotatably mounted. Chains (19) secured at one end to the support (10,11) are entrained around pulleys (18) and support a yoke (20) on which is mounted a crown block (21). A cable (22) is reeved around crown block (21) and around a travelling block (23) which carries a tool carrier (24). The two ends of cable (22) are reeved around two second pulleys (26A,26B) rotatably mounted on the cross-head (17). End (22A) of cable (22) is connected to a draw-works and end (228) of cable (22) is connected to a tie-down.
