Definitions

  • the invention relates to a cargo vessel adapted to be powered by LNG, said cargo vessel being in particular a maritime vessel and having a hull, a stern, a bow, sides, and a propulsion system.
  • Such vessels generally comprise an LNG fuel tank in the vessel's designated engine bay area, with space for cargo containers in the designated cargo area of the vessel.
  • LNG is condensed natural gas that is cooled to its liquid form at approximately -160 Degrees Celsius, and in its liquid form, LNG occupies approximately 1/600 th of the volume of natural gas in its gaseous form.
  • the significant difference in density makes it profitable to transport gas in its liquid form from remote and isolated gas fields to markets worldwide.
  • the transporting of LNG by means of vessels utilizing the waterways is common practice today.
  • the LNG is transported by relatively large so-called LNG carriers from a producer such as e.g. Qatar Gas to its destination where the LNG is off-loaded in a dedicated LNG storage facility which could hold anywhere from 10.000-500.000 cubic meters of LNG or more.
  • the LNG is further distributed either by smaller LNG carriers, or it could be used in the form of bunker fuel e.g. in cargo vessels using LNG for propulsion, or the LNG could be gasified and distributed through a natural gas grid.
  • US2010/0162939 discloses an LNG tanker able to transport LNG by means of dedicated insulated tanks positioned in the cargo area of the tanker.
  • WO 201 1/053164 discloses an LNG fuel tank system for at least one gas engine used for ship propulsion comprising at least one LNG fuel tank and an intermediate gas pressure vessel.
  • the LNG tank may be bunkered from an onshore LNG pressure tank filling facility (such as a LNG storage facility) by means of a LNG filling line.
  • the ship may be operated using fuel from the LNG tank or e.g. accumulated boil-off gas (BOG).
  • BOG accumulated boil-off gas
  • US2009/0253318 discloses a marine vessel with gaseous fuel, having at least one gas powered engine, which vessel is provided with a fuel tank arrangement in which the fuel is stored in liquid phase.
  • US6640554 discloses a portable self-contained liquid natural gas (LNG) dispensing system which is housed in a container. A bulk tank positioned within the container contains a supply of LNG.
  • LNG liquid natural gas
  • a cargo vessel adapted to be powered by LNG, said cargo vessel having a hull, a stern, a bow, sides, and an engine, said vessel comprising: a fuel distribution system being adapted for preparing and distribution of LNG to be used as fuel; a cargo area designated for storage of one or more containers such as ISO containers; said cargo area being designated for storage of one or more LNG containers, an engine adapted to be powered by LNG for powering said cargo vessel; an LNG tank positioned within said hull and being in fluid communication with said engine via said fuel distribution system; an LNG tank-pipeline connecting said LNG tank to said fuel distribution system; and an engine-pipeline connecting said fuel distribution system to said engine.
  • the vessel according to the invention comprises a manifold having a manifold inlet and a manifold outlet, said manifold inlet having couplings configured to be connected to complementary couplings on one or more LNG containers positioned in said cargo area; said vessel comprising a first supply pipeline connecting said manifold outlet to said LNG fuel tank.
  • the vessel's LNG tank may be connected to one or more LNG containers in the vessel's cargo area.
  • This provides the advantage that LNG can be distributed between the LNG fuel containers and the vessel's own LNG tank and thereby it is also possible to distribute the transferred LNG further to the distribution system for supply to the ship's engine (i.e. its propulsion system).
  • the supply system renders possible a more easy access to and use of natural gas aboard maritime type vessels.
  • the manifold may preferably have multiple inlets and a single outlet. In some embodiments, the manifold may have more than one outlet.
  • said vessel may comprise a second supply pipeline connecting said manifold outlet to said fuel distribution system.
  • the vessel comprises a manifold outlet valve being capable of switching the manifold outlet between said first supply pipeline and said second supply pipeline.
  • the manifold outlet valve may be capable of connecting said manifold outlet with both said first supply pipeline and said second supply pipeline simultaneously. This allows the possibility of transferring LNG from (or to) the LNG fuel containers to the distribution system and to the internal LNG tank simultaneously. Such an arrangement may be beneficial in order to rapidly deplete the LNG stored in the LNG containers. These, when empty, may be exchanged, at an appropriate docking and loading location, for filled LNG containers.
  • the vessel comprises a first distribution pump being capable of pumping LNG through said first supply pipeline in a direction from said one or more LNG fuel containers stored in said cargo area to said LNG fuel tank.
  • said vessel comprises a second distribution pump being capable of pumping LNG through said first supply pipeline in a direction from said LNG fuel tank to said one or more containers containing LNG stored in said cargo area.
  • said distribution pumps may be a same pump, which may be a reversible pump.
  • the invention may therefore allow a single pump to provide the function of either pumping LNG from the vessel's LNG tank to one or more of the containers containing LNG or in the opposite direction, and thereby cost as well as space could be saved while essentially maintaining the corresponding function.
  • said manifold inlet may comprise valve means capable of selectively connecting said one or more LNG container stored in said cargo area to said manifold inlet.
  • the engine can be supplied with LNG originating from one or more selected containers containing LNG being placed in said cargo area.
  • LNG can be supplied to the engine from selected containers being placed in the cargo area.
  • the vessel comprises a first fuel supply pump being capable of pumping LNG through said second supply pipeline from said one or more LNG fuel containers stored in said cargo area via said manifold to said distribution system.
  • the vessel comprises a second fuel supply pump capable of pumping LNG from said LNG fuel tank to said fuel distribution system.
  • the invention comprises a method for refuelling a cargo with LNG, said method comprising the steps of;
  • LNG tank positioned within the hull
  • stationary LNG tank or "internal LNG tank”
  • internal LNG tank they are all to be understood as covering the same subject matter, notably, a vessel's own LNG tank.
  • a vessel may in particular comprise more than one such LNG tank.
  • a vessel's LNG tank has a considerably greater capacity (volume) than a standard (e.g. ISO) LNG tanktainer.
  • an engine could be any suitable ship's propulsion system and may in particular include a dual- fuel piston engine able to operate not only on commercial fuel such as marine diesel, bunker oil or like but also gas, such as vaporized LNG.
  • the engine could also, by way of example, be a gas turbine or a steam engine using e.g. a boiler as heat source.
  • LNG is a liquid and a combustion engine normally does not run on liquid fuel but rather gasified fuel
  • the engine is supplied with LNG, it is normally meant that the engine is supplied with a gas originating from gasified LNG mixed with air, thereby providing a gaseous fuel on which the engine can operate.
