    • A method for converting a hydrate-forming gas (2) into a hydrate (5), as the gas (2) combines with a hydrate-forming liquid (3) which is supplied to the gas (2) in finely dispersed shape at hydrate generating pressure and temperature conditions. A subsequent storing and/or transportation of said gas (2) in the shape of gaseous hydrate (5) may also be included. The converting process takes place in at least one chamber (1), as the following process steps are undertaken. Said gas (2) is supplied to the chamber (1) at a hydrate-forming pressure, preferably equal to the working pressure of said gas and at a random temperature, preferably equal to the working temperature of said gas. A temperature controlling medium (11), preferably having a high heat capacity, is guided into the gas-filled portion of said chamber (1) at a temperature below the hydrate generating temperature of said gas (2), and the temperature controlling medium (11) is guided out of the chamber (1), after having passed through the chamber (1) in direct contact with said gas (2) and said hydrate-forming, finely dispersed liquid (3), the medium hereby bringing out at least a substantial part of the latent heat liberated during the generation of said hydrate (5).

    • A method and a vessel for offshore oil loading, wherein the vessel comprises a number of centre tanks (3) arranged in the longitudinal direction of the vessel, and a number of wing tanks (5, 6) located in pairs on either side of respective centre tanks, a loading line (19) being connected to the centre tanks (3) via respective valves (20), and adjacent centre tanks (3) being connected to each other via bulkhead valves (18). The method comprises the steps of a) firstly effecting filling of a desired number of the centre tanks (3), these being substantially narrower and having a correspondingly smaller volume than the wing tanks (5, 6), b) thereafter opening bulkhead valves (17) between a centre tank (3) and an appurtenant wing tank pair (5, 6), and sluicing out oil from the centre tanks (3) into the two wing tanks (5, 6) by means of the static pressure from the centre tanks, the bulkhead valves (18) between the centre tanks (3) being open, so that the wing tank pair (5, 6) is filled as quiclky as possible by suitable operation of the bulkhead valves (18) between the centre tanks (3) and of the valves (20) of the loading line (19) to the centre tanks (3), c) closing the bulkhead valves (17) to the two wing tanks (5, 6) when these and the appurtenant centre tank (3) are filled to a desired level, and d) repeating the filling process according to the steps b) and c) successively for additional wing tank pairs (5, 6) after that all centre tanks (3) have been filled again.

    • L'invention se rapporte à un procédé de chargement et de déchargement de pétroliers (1) transportant du pétrole, à un procédé de transport de pétrole dans des pétroliers (1) et à un système de tuyau et de vanne (6, 7, 8) dans un pétrolier (1), servant à effectuer ce procédé. Selon l'invention, le dégagement de gaz contenant des hydrocarbures au cours du chargement ou du déchargement des pétroliers est réduit lorsqu'on charge ou qu'on décharge les citernes (2) tout en maintenant le pétrole en contact avec un gaz contenant des hydrocarbures généralement saturés. On effectue ceci en réservant le gaz contenant des hydrocarbures qui est produit au cours du chargement ou du déchargement, ce gaz étant plus tard utilisé pour d'autres chargements ou déchargements. Ceci est rendu possible par un système de tuyau et vanne (6, 7, 8) utilisés selon cette invention. Selon un mode de réalisation, les citernes sont entièrement remplies, de sorte que le pétrole parvient jusqu'à l'intérieur d'écoutilles (10) et de conduites ascendantes (11) situées au sommet des citernes (2). Il en résulte que le volume de gaz au-dessus de la cargaison avant un échouage éventuel est app roximativement égal à zéro, et, en conséquence, la dépression nécessaire est obtenue au-dessus de la cargaison afin qu'un équilibre hydrostatique soit établi au fond du pétrolier (1), ce qui produit un débordement minimal de la cargaison.
