Title (EN) LOW MOTION SEMI-SUBMERSIBLE
(FR) STRUCTURE SEMI-SUBMERSIBLE À FAIBLE DÉPLACEMENT
Abstract:
(EN) The present invention relates to a semi-submersible offshore structure. More particularly, the invention relates to a low motion semi-submersible offshore structure that has improved stability in deep water. The low motion semi-submersible experiences relatively lesser heave, pitch and wave motions compared to conventional semi-submersibles when the semi-submersible is operating in harsh offshore environments.
(FR) La présente invention concerne une structure offshore semi-submersible. Plus particulièrement, l'invention concerne une structure offshore semi-submersible à faible déplacement qui présente une stabilité améliorée en eau profonde. La structure semi-submersible à faible déplacement connait des mouvements de pilonnement, de tangage et des mouvements ondulatoires relativement moins importants que ceux ressentis par les structures semi-submersibles classiques lorsque la structure semi-submersible est utilisée dans des environnements offshores difficiles.
