A system for use with a Luxury Boat, when the Luxury Boat is in Temporary Dry Storage involves a sensor is configured to sense a trigger signal from a boat-based pump controller indicating that raw water is to be pumped to at least one Auxiliary System and send a signal to a second controller that will cause the second controller to start a pump, external to the Luxury Boat, pumping antifreeze from a reservoir to at least one Auxiliary System on the Luxury Boat in Temporary Dry Storage. An associated method is also disclosed. A system involving a a raw water collar that forms a seal against a hull of a Luxury Boat about a scoop strainer of the Luxury Boat through which raw water can be supplied when the Luxury Boat is in Temporary Dry Storage is also described.

Disclosed is a water intake system for a floating vessel in a body of water, which includes within the hull of the vessel an intake compartment for taking in water from the body of water and a distribution compartment for distributing and supplying the water to one or more consumer units within the floating vessel. The intake compartment is arranged below a lowest operational draught of the vessel and has an inlet in a bottom region of the intake compartment. The intake compartment is coupled by a conduit to the distribution compartment for allowing water to flow into the distribution compartment. The water intake system further includes a water lift hose that is connected to the inlet and is extendible below the hull of the vessel.

A negative pressure aeration system, created by atmospheric siphon pressure above the waterline and mechanical pump suction below the waterline, which impedes the growth of organic matter. A waterfall in vacuum effect is created within a processing unit that aerates the raw water as it falls through the air chamber of the processing unit housing, which assists in the suppression of organic growth by reducing the contact surface area within the processing unit. A chemical tank allows an anti-fouling chemical to be added to the entire system and a power supply allows flexible electrodes driven by a vacuum to create a further anti-fouling benefit throughout the components of the system.

A sea water intake riser system for a floating production unit, including a caisson having a through-opening in a bottom side and being connectable to an upper end of a riser pipe; a lift pump inside the caisson and having an inlet at a vertical distance with a predetermined minimum submergence for pumping cold water from the caisson up to the floating production unit for use as cooling medium, wherein the sea water intake riser system includes at least two caissons, having a height substantially equal to a vertical height of a hull of the floating production unit and including an open top side; each caisson extending from a predetermined minimum distance from the bottom side of the hull up to at least the water-line during use and wherein a sump tank is located between the bottom side of the hull and the at least two caissons.

The present disclosure relates to a pump system including a pump and a liquid detection sensor or a flow sensor for sensing liquid presence or liquid flow. The water pump system also includes a controller that interfaces with the liquid detection sensor or flow sensor and uses data from the liquid detection sensor or the flow sensor to prevent the pump from being damaged under a run-dry condition.

A slide-in structural interface between a Sea Water Intake Riser (SWIR) and a floating unit hull or sump tank bottom plate permits a pull-in, diver-less installation of the SWIR. Certain embodiments include an integrated, easily maintainable strainer.

A method for operating a cooling system of a ship, having a sea water part system with a sea water pump (14a, 14b) and at least one first cooling water circuit. The first cooling water circuit includes a bypass in a heat exchanger coupling the sea water part system and the first cooling water circuit and a control valve. A position of the control valve determines a cooling water proportion of the first cooling water circuit that is conducted via the heat exchanger and a cooling water proportion of the first cooling water circuit that is conducted via the bypass. The position of the control valve is controlled such that an advance cooling water temperature corresponds to a set point value. The rotational speed of the sea water pump is controlled based on the position of the control valve.
