A floating photovoltaic (PV) system that has a float and at least one PV module. The float is made of two layers, a lower water-permeable layer and an upper water-non-permeable layer. The two layers are held together in a stack configuration, so that when the system is placed in a body of water, the lower layer remains substantially submerged below the surface of the water and the upper layer floats at or above the surface of the water.

A system and method in which a buoyant central docking station captures, lifts and couples one or more other sea vessels is disclosed, wherein a flexible, modularized production system is quickly realized on a cost effective basis. The capabilities of a number of older, less expensive, readily available vessels are combined to achieve an effective FPSO substitute that allows lower producing fields to be explored and produced in a profitable manner. The time horizon between initiation and consummation of field operations is reduced, and older vessels that might otherwise be scrapped or retired are again made useful and seaworthy in a safe and profitable exploration and production environment.

The application relates to a floatable offshore wind turbine with at least one floatable foundation. The floatable foundation includes at least one floating body. The floatable offshore wind turbine includes at least one anchoring arrangement configured to fix the offshore wind turbine to an underwater ground while the offshore wind turbine is in its anchoring state. Further, the floatable offshore wind turbine includes at least one height adjustment device configured to change the vertical distance of the floatable foundation to an underwater ground surface of the underwater ground and/or to a water surface during the anchoring state based on at least one specific meteorological environmental parameter of the offshore wind turbine.

A system for preventing damage to a power cable for electric power transmission to and from and within a floating offshore wind power plant using non-redundant mooring, after failure of a main loadbearing mooring element is described, comprising at least one power cable safety line having the following properties: It is connected to the same two wind turbines as the power cable it is designed to protect. It has an effective length shorter than the power cable it is designed to protect. It has an effective length longer than what is needed to remain largely unstressed when the distance between the floating wind turbines with intact mooring systems is at its maximum. It has a breaking strength being a predetermined fraction of the strength, which the main loadbearing mooring elements are designed for.

Systems, devices and methods enable generation and monitoring of support platform structural conditions in a manner that overcomes drawbacks associated with conventional approaches (e.g., load cells) for generating and monitoring similar operating condition information. In preferred embodiments, such systems, devices and methods utilize fiber optic strain gauges (i.e., fiber optic sensors) in place of (e.g., retrofit/data replacement) or in combination with conventional load cells. The fiber optic sensors are strategically placed at a plurality of locations on one or more support bodies of a support platform. In preferred embodiments, the fiber optic strain gauges are placed in positions within a hull and/or one or more pontoons of an offshore platform. Such positions are selected whereby resulting operating condition data generated by the fiber optic strain gauges suitably replaces data received by conventionally constructed and located load cells of an offshore platform (e.g., a TLP).
