A foundation system for the foundation of an offshore structure includes a monopile having an anchoring portion anchorable in a seabed and a connection portion disposed at the opposite end. A platform structure is connected directly to the connection portion of the monopile or indirectly via a transition piece. The platform structure is disposable above a water surface. The foundation system includes at least two stabilizing devices connected directly to the platform structure or indirectly to the platform structure via the transition piece. The stabilizing devices are attachable to the seabed such that tensile forces or compression forces are transmittable between the seabed and the platform structure. Securing points on the stabilizing devices, together with the connection portion of the monopile, define a plane having a horizontally extending component.

In a shallow water anchor of a parallelogram design which lowers a rod down from a fishing boat into contact with the ground to keep a boat from drifting out of a chosen location, a depth the rod can reach depending on the combined extended length of the unfolded parallelogram and the length of the vertical rod, a first improvement to increase the maximal depth without concomitantly increasing the length of the parallelogram frame, the improvement using the relative motion and geometry of parallelogram parts to lengthen a telescoping rod, and a second improvement of a flexible coupling to an electric drive motor.

Disclosed are a semi-submersible raft wind power generation unit and a construction method therefor. The raft wind power generation unit includes at least three floaters (12) and at least three wind turbines (21) configured to be placed on the floaters (12). The raft is configured to turn about a vertical axis and be fixed to a seabed (2) by a mooring line (36). A force resultant from an incoming wind load passes closely around the center of geometry of the raft, which is a distance away from the center of rotation of the raft so that a yaw moment about the center of rotation is created that rotates the raft until the force resultant passes through the center of geometry and center of rotation

A flowing-water driveable turbine assembly (104) for location in river or sea areas with unidirectional and bidirectional water flows. The turbine assembly comprises a turbine support (106) with positive buoyancy in water. The turbine support (106) is arranged to be anchored by an anchoring system (108) to a water bed. The turbine assembly comprises at least one turbine (110). The positive buoyancy of the turbine assembly in water has an upward force to constrain the turbine support 106 and the at least one turbine (110) to a position of floating equilibrium against a downward force of the anchoring system (108). The turbine assembly may have variable buoyancy, a duct around each turbine for directing water through the turbine to generate power from water flow, and a winch or winches for submerging the turbine assembly or parts thereof.

A towing anchor capable of extending wing plate and an installation method therefor are provided. The towing anchor includes a main anchor plate and two wing plates which can slide outwards relative to the main anchor plate and will not be detached from the main anchor plate. The main anchor plate is anchored with a mooring steel cable connected to a towing vessel. The main anchor plate is further provided with a limit cable-receiving groove, in which first, second and third fixed pulleys are respectively provided correspondingly to each of the two wing plates. One end of a tensioning steel cable is fixed to an inner edge of the wing plate, and the other end of the tensioning steel cable sequentially surrounds the third, second, and first fixed pulleys and then passes through an opening formed at middle position of the groove to be connected to the towing vessel.
