A method of operating a hydrocarbon production system. The hydrocarbon production system including a gas turbine engine configured to combust hydrocarbon gas produced at the hydrocarbon production system and to provide power for the hydrocarbon production system as a result of the combustion. The method includes combusting produced hydrocarbon gas in the gas turbine engine, capturing carbon dioxide exhausted from the gas turbine engine as a result of the combustion of the hydrocarbon gas, storing the captured carbon dioxide at the hydrocarbon production system in a first set of storage pipes, and transporting the stored carbon dioxide away from the hydrocarbon production system for permanent storage.

A method is for the treatment of ballast water, in which the ballast water is carried into a ballast tank via a down pipe and in which an underpressure created at the upper portion of the down pipe induces the formation of gas bubbles in the ballast water. Before flowing into the down pipe, the ballast water is carried via a throttling device into a closed container at the upper portion of the down pipe, the closed container having a flow area larger than the flow area of the down pipe.

Method and device for treatment of water

A method and device are provided for reducing the oxygen content of seawater, where the seawater is introduced into the upper part () of a downcomer (), particularly for treatment of ballast water in a ballast tank () of a ship (). A seawater intake pipe () runs from the outside of the ship to a ballast pump () that is designed to pump the water on through a pump pipe () and up to the upper part of the downcomer. The downcomer extends mainly vertically down to the ballast compartment of the ship, where the ballast water can be distributed between several ballast compartments by means of distribution headers and valves. One aim of the invention is to neutralize organisms in the ballast water.

Method and device for removal of gases from water

A method and arrangement for reducing the evaporation of volatile organic compounds (VOC) or other gases during the filling of an essentially liquid petroleum product on a storage and/or transport tank () via a feed pipe (), and where the petroleum product is led into the storage/transport tank via a loading column () having a significantly larger cross section than that of the feed pipe ().

Method and arrangement at a loading column

A device for condensing volatile organic compounds (VOC) from a storage or transport tank () into oil from the same or another storage or transport tank () via a downcomer (), where the upper part () of the downcomer (), which upper part has a cross sectional area that is essentially unreduced, is connected to a gas pipe (), the gas pipe () communicating with the upper part () of the storage or transport tank (), and where the upper part () of the downcomer () is arranged at a sufficient height above the upper part () of the storage or transport tank () to cause an inflow of gas from the upper part () of the storage or transport tank () due to the underpressure created in the upper part () of the downcomer () when oil flows down through the downcomer ().

A method and a device for protecting a vessel's loading space, the hold () of the vessel being provided with cargo pressure tanks (), from excess pressure if a gas leakage should occur in the hold (), the vessel being provided with a ventilating duct () which is separated in a gastight manner from the remaining rooms of the vessel and extends along the hold () of the vessel.

Method and device for protecting a vessel's loading space from excess pressure

A device for reducing evaporation of volatile organic compounds (VOC) during filling of a substantially liquid petroleum product into a storage and/or transportation tank () via a down pipe (), wherein the down pipe (), which has a non-constricted flow-section, is provided with an inlet () for gas at its upper portion, the inlet () being arranged to enable inflow of gas due to the underpressure being formed in the upper portion of the down pipe () when the petroleum product flows down through the down pipe ().

Device for reducing separation of volatile organic compounds from oil during filling of tanks

A device for a pipe () in a cargo pressure tank of a ship (), the pipe () mainly being used for loading and unloading of fluids, and the open end portion () of the pipe () being placed immediately above the lower bottom section () of the cargo pressure tank ().

Loading pipe in a cargo pressure tank of a ship

A device for and method of fixing vertically installed cargo pressure tanks (), particularly the type used for sea transport of pressurised petroleum products, wherein at least two cargo pressure tanks () constitute a liftable cassette (), the tanks () of which preferably are placed in the upright position on a cassette lifting frame () and are interconnected by means of a guide frame ().

A method of separating volatile organic components, so-called VOC, from crude oil, where, as it is loaded onto a ship, the crude oil is passed into a process vessel () in which is established a negative pressure adjusted according to the vapour pressure of the oil, from where the liquid phase of the crude oil flows to the ship's cargo tanks, while the gas phase, the VOC, is extracted from the process vessel ().

Method and a device for loading petroleum

A method and a device for reducing the evaporation of volatile organic compounds (VOC) when an essentially liquid petroleum product is being filled into a storage and/or transport tank () through a drop line (), possibly also through a loading point (), in which a gas or mixture of gases is supplied to the upper portion of the drop line () or the loading point () during the filling operation.

Method and device for reducing the separation of volatile organic compounds from oil during filling of tanks

A device by pressure vessels () for sea transport of petroleum fluids, where at least two pressure vessels () are connected to and communicate with a manifold ().
