MULTIPURPOSE UNIT WITH MULTIPURPOSE TOWER METHOD FOR TENDERING WITH A SEMISUBMERSIBLE Abstract Disclosed herein is a semisubmersible multipurpose unit (MPU) (10) having a deck (600), a multipurpose tower (60) secured to the deck, supports (402, 404, 405), pontoons (80, 82) connected to the supports with each pontoon for ballast transfer, at least two hawsers (32, 34) connected to the MPU for connecting the MPU to an 5 object (11) at sea having a mooring system, a hawser guidance system (300) to direct each hawser to the object at sea, a crane (60) secured to the deck of MPU, and at least 6-point mooring system (12, 14, 16), the combination of the MPU, hawsers and mooring system create a global equilibrium between the mooring system of the object at sea and the at least 6-point mooring system and the hawsers have both an elasticity 1o sufficient to accommodate the wave frequency between the object and the MPU and a stiffness adequate to synchronize the average and low frequency movement during a 10-year storm. 1269353 DOC IRN: 955298DI |
