Abstract: This disclosed embodiments of this invention relate to a semi-submersible vessel. The semi-submersible vessel includes a deck, at least four columns supporting the deck, a first pontoon, a second pontoon, a first brace and a second brace. Each column comprises an outer skin, an inner skin, and a number of reinforcing plates spaced apart from each other and connecting the inner skin to the outer skin, forming a double skin arrangement. The first pontoon is connectable to a first pair of columns and the second pontoon is connectable to a second pair of columns. The first brace is connectable to the first of each of the two pairs of columns and the second brace connects the second of each of the two pairs of columns.

Abstract: This invention relates to a pipe-like appendage for a sharp-edged pontoon of an offshore vessel, a pontoon structure comprising the pipe-like appendage and a method of converting a sharp-edged pontoon into a pontoon comprising at least one rounded-edge.

Abstract: 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.

Abstract: This invention relates to a subsea Remotely Operated Vehicle (ROV) hub. In particular, the invention relates to a subsea ROV hub comprising a plurality of compartments for housing and deploying a plurality of ROVs.

Abstract: A rapid transition floating vessel that is able to follow the yaw motions of a turret moored floating vessel is provided. The rapid transition floating vessel includes a system and processes for dynamically positioning the floating vessel alongside a turret moored floating vessel whereby the floating vessel remains at a safe distance while being connected to the turret moored floating vessel. This is achieved by the floating vessel following the yaw motions of the turret moored floating vessel as the turret moored floating vessel weathervanes about a center of the turret moorings.

Abstract: A semi-submersible platform that is suitable to serve as a logistics hub at a remote offshore location. The semi-submersible platform is configured in a V-shape to reduce motion of the semi-submersible platform caused by rough sea conditions. The semi-submersible platform has a vessel docking area within the platform and a balancing unit to balance the unsymmetrical load of the platform that protects a vessel in the docking area from rough sea conditions.
