Abstract: A tank for farming of marine organisms is described, where the tank includes a main chamber to hold the marine organisms and where the tank has further chambers to treat the water before it is circulated back to the main chamber.

Abstract: A method and system for measuring an amount of a gas dissolved in a liquid is described, in which the liquid is transferred to an equilibrator and in which the amount of the various gases is measured in the gas phase of the equilibrator and that a calculation of the amount of gas which is dissolved in the liquid is carried out.

Abstract: Apparatus (10) for removing gases in a liquid, and/or for removing foam and particles from a liquid and/or for the transport of liquid, the device (10) comprises conduits (16) for transporting the liquid from a first location to a second location, where the conduit (16) comprises a first upstream conduit portion (16a) for receiving of liquid, a substantially horizontal conduit portion (16b), a downstream conduit portion (16c) to discharge liquid out of the conduit (16), and a venting conduit portion (16d) to discharge gases, particles and a part of liquid out of the conduit (16) via conduit portion (16e) and means (17) arranged in the upstream conduit portion (16a) and/or horizontal conduit portion (16b) for supplying microbubbles to the conduit (16), and that in the conduit (16) means (19) are provided for establishing vacuum in parts of the conduit (16), characterized in that the device (10) in the conduit portion (16b) comprises two or more venting conduit portions (16d).

Abstract: A system for hydraulically controlling a subsea device includes a compensator provided within a cavity of a well system, a hydraulic connection between the compensator and the subsea device, a pressure regulator arranged to regulate the hydraulic pressure provided to the subsea device and a ventilation tool for releasing pressure at the subsea device.

Abstract: A net cage for farming of marine organisms is described, where the net cage is comprised of a main chamber to hold the marine organisms and where the net cage has further water chambers to treat the water before it is circulated back to the main chamber.

Abstract: A system for hydraulically controlling a subsea device includes a compensator provided within a cavity of a well system, a hydraulic connection between the compensator and the subsea device, a pressure regulator arranged to regulate the hydraulic pressure provided to the subsea device and a ventilation tool for releasing pressure at the subsea device.

Abstract: A method of treating water, applicable to sterilise water for drinking or to treat ballast water, may include flowing water through a conduit containing a reduced pressure zone arranged to reduce the pressure of the flow by at least 102 to a sub-atmospheric pressure. The method may include passing water through a siphon conduit having a headspace provided with a gas removal pump.

Abstract: The invention provides a method of preparing pelletized aquaculture feed for administration to farmed aquatic animals. The method may include the steps of causing water to circulate in a loop conduit, introducing aquaculture feed pellets into the water circulating in the loop conduit whereby to expose the pellets to pressure changes and thereby cause the pellets to become water-impregnated, and retrieving the water-impregnated aquaculture feed pellets from the loop conduit.

Abstract: The invention provides a method of producing an aquaculture feed composition which method comprises causing water, optionally together with a lipid, to be taken up by protein-containing feed pellets, characterised in that said pellets contain as a binder a plant seed flour.
