Abstract: A transportation device for an offshore platform, including a vessel and a floating structure which are fixedly connected. The floating structure is placed on a sea surface and is configured to assist the vessel to sail. The floating structure is provided with an adjustment mechanism which is configured to adjust the floating structure to rise and fall relative to the sea surface. A rail is arranged on the vessel and is in sliding connection with the topside module, so that the topside module slides onto the vessel from land. During the transportation of the topside module, the buoyancy of the floating structure is adjusted through the adjustment mechanism, so that the floating structure provides sufficient anti-rolling moments beside the vessel, thereby reducing the vibration of the topside module caused by the winds and waves during the sailing and reducing the potential damage to the topside module.

Abstract: Disclosed is a combined structure of a fishing net cage and floating wind turbine foundation. The combined structure includes a wind turbine and a polygonal deep-sea fishing net cage floating body. The polygonal deep-sea fishing net cage floating body comprises an upper polygonal floating body frame, a bottom ring beam, and a middle truss structure, and a connecting column disposed between the upper polygonal floating body frame and the bottom ring beam. A connection structure of the wind turbine set is disposed on the upper polygonal floating body frame. The bottom of the polygonal deep-sea fishing cage floating body is provided with an interface connected with a steel cable of a mooring system. A sub-tank capable of providing ballast by loading water and buoyancy is disposed in the polygonal deep-sea fishing net cage floating body.

Abstract: Disclosed is a wind turbine generator foundation with pressure-dispersive pre-stressed anchor rods or anchor ropes. The foundation comprises a pile cap, a plurality of foundation piles arranged circumferentially at the bottom of the pile cap at uniform spacing, and a wind turbine generator tower connected to an upper part of the pile cap.
