Abstract: Floating support for a wind turbine including a central support member, and at least three buoyancy assemblies, each connected to the central support member via a radial connector beam and mutually interconnected via a transverse connector beam, wherein each buoyancy assembly includes a connector body having two radial sides, an outward and an inward transverse side, wherein two transverse connector beams and a radial connector beam extend away from the inward transverse side of the connector body, an anchor is provided at or near the outward transverse side of the connector body and the radial sides of the connector body are each connected to a respective buoyancy element.

Abstract: Offshore hydrocarbon (e.g. oil) production units that produce considerable contaminated water (produced water), are able to repeatedly dispose of the produced water so each production unit requires only a moderate-sized tank to hold the produced water, and most of the tank storage capacity of the production unit can store hydrocarbons. A mobile water-treatment plant is provided on a converted tanker that sails from one production unit to another one, transferring produced water from the oil production units and separating out contaminants as by settling, to leave clean water that can be dumped into the sea and contaminants that cannot be dumped into the sea. The mobile plant occasionally sails to an on-shore facility where it is allowed to dump contaminants.
