A hull for a semi-submersible wind turbine platform capable of floating on a body of water and supporting a wind turbine includes a keystone and at least three bottom beams extending radially outward of the keystone. Each bottom beam has a primary beam portion and a column base portion, wherein the column base portion is configured to support an outer column of the hull thereon, and wherein the primary beam portion defines a first ballast compartment therein. The first ballast compartment is in fluid communication with water in the body of water in which the hull is floating.

A vessel has a compartment (34) for containing water, which compartment (34) has at least one opening (31) in a wall (30) thereof for allowing water to pass therethrough. The compartment (34) comprises an assembly (1) of a grating (10) and at least one anti-biofouling source (20), the grating (10) being positioned in the opening (31) for blocking items from passing through the opening (31) along with the water, and comprising a number of elements and spaces between the elements, and the anti-biofouling source (20) being configured to emit ultraviolet light during operation thereof for realizing anti-biofouling of at least a portion of the grating (10). At least one of the elements of the grating (10) is at least partially transparent to the ultraviolet light, enabling a design of the assembly (1) in which anti-biofouling of the entire grating (10) may be guaranteed.

The invention relates to a regulator for compensating level variations of water surface in conjunction with a water intake opening. The regulator includes a shutter member (11) to be moved vertically, which can be moved between the open position and the closed position, whereby while in the open position, the shutter member (11) opens a flow path to enable stream of water, and while in the closed position, the shutter member closes the flow path. According to the invention, the regulator includes a float (4) connected to the shutter member (11), which has been arranged before the shutter member (11) in the flow direction and dimensioned to float in a given depth, and which as the water level (13) sinks, moves the shutter member (11) toward the closed position.

The invention relates to a sea chest cooler on ships and offshore platforms, comprising an integrated antifouling system for killing barnacles, mussels, and other fouling organisms by means of an overheating process that can be regularly repeated. The aim of the invention is to design a sea chest cooler in such a way that a simple device can automatically protect the sea chest cooler (16) against microorganism fouling both in the actual cooling mode and during a standstill by continuously overheating a defined number of heat exchanger tubes (20) without interrupting the cooling process, if possible using waste heat from the cooling water. Said aim is achieved by arranging the heat exchanger tubes in a circular manner in special sections of the sea chest cooler (16) such that hot water is supplied to individual circular segments of the tube bundle during or outside the cooling process by means of a mechanical device. Said thermal antifouling system (TAS) device (13) comprises a TAS nozzle (1) which rotates in angular steps and separates heat exchanger tubes (20) of the sea chest cooler (16) from the cooling process. The invention has the advantage that the cooler design is adapted to the simultaneous cooling and antifouling function and that the sea chest cooler comprising the integrated TAS device can be protected against fouling by using the waste heat from the cooling water without interrupting the cooling process.
