Definitions

  • the present invention relates to the use of natural gas as a fuel for ships and boats. Emissions from boats and ships - from their engines - have long been a target of regulation, yet despite this there are still few regulations in place to control/eliminate those emissions.
  • Natural gas has been explored as a potential solution to this problem since it is a relatively clean fuel to burn in engines compared to the conventional fuel - diesel. However, it is less fuel efficient than diesel, and in its most space-saving form - LNG - it requires space hungy cooling equipment since it needs to be stored at very low temperatures. Therefore, natural gas has been seen to be too space-hungry for it to be an alternaive fuel for the conventional diesel. An alternative solution is therefore required in order to comply with future regulations on emissions from watercraft.
  • a watercraft comprising a diesel fuel tank for fuelling general shipping requirements of the watercraft such as motoring from one location to another, wherein the watercraft additionally has a CNG pressure vessel thereon for storing CNG therein, said CNG being useable by the watercraft, from the pressure vessel, for powering an engine for coastal manoeuvering of the watercraft.
  • the engine is a duel fuel engine, capable of running in a first configuration on diesel from the diesel fuel tank, and in a second configuration on CNG from the pressure vessel.
  • a duel fuel engine capable of running in a first configuration on diesel from the diesel fuel tank, and in a second configuration on CNG from the pressure vessel.
  • the watercraft is preferably a ship for carrying cargo.
  • the cargo may be CNG or containers or oil.
  • the watercraft might instead be a passenger ferry.
  • the watercraft is a CNG tanker comprises a plurality of pressure vessels for the transportation and distribution of CNG between the locations.
  • the pressure vessel for supplying the enginge with fuel is one of the plurality of pressure vessels, although it may instead be a dedicated pressure vessel, or a dedicated set of pressure vessels.
  • CNG is typically transported within a tanker at storage pressures in excess of 200 bar.
  • the CNG within the fuel supplying pressure vessel may likewise be stored at such pressures.
  • a regulator can be provided between the fuel supplying pressure vessel and the engine to ensure a steady fuel-supply pressure to the engine.
  • the CNG used to power the engine when on a CNG tanker, is residual CNG, the residual CNG being extracted from a pressure vessel that has had its transportation quantity substantially offloaded therefrom, the residual CNG therefore being the CNG that remains therein after the offload, it being at a pressure below 100 bar.
  • the CNG is extracted from the plurality of pressure vessels via pipework connected to the lower end of the or each pressure vessel.
  • CNG CNG
  • the fuel for the engine near the coast e.g. as the watercraft pulls up alongside the dockside, and while docked, there will be reduced emmisions from the engines as compared to that produced by conventional diesel powered engines. Further, the emissions will be adequately clean to allow the engine to remain running while the watercraft is at the dockside for providing the watercraft's electrical requirements. As a result, the watercraft will not need to cold iron off the local power supply, although that is still an option if desired. Due to the residual pressure of the CNG being significant, no fuel pump is needed to supply the CNG to the engine - it will be self-feeding.
  • CNG is stored onboard the ship substantially at room temperature, rather than at the cryogenic temperatures required for LNG, no (or only minimal) cooling or heating mechanisms are needed onboard the watercraft. Further, since only coastal operations will be fuelled by CNG, the stored volumes of CNG are controlled to a manageable level. Yet further, due to the buoyancy of CNG, and pressure vessels containing it, the presence of the pressure vessel on board the watercraft will not cause a buoyancy issue for the watercraft.
  • the pressure vessel(s) are formed of composite materials, and comprise type 3 or type 4 pressure vessels.
  • CNG is the primary cargo of the ship, with no other cargo having a greater storage volume demand compared to the CNG.
  • the pressure vessels are at least 15m long and at least 2m diameter.
  • the present invention also provides a method of providing propulsion on a watercraft as defined above, comprising powering the engine of the watercraft by burning CNG stored on the watercraft when the watercraft is undertaking coastal manoeuvering, and using a different powersource for longer range journeys.
  • the different power source is diesel and a diesel engine.
  • Figure 1 illustrates a cargo vessel for implementing the present invention
  • Figure 2 illustrates a passenger ferry for implementing the present invention
  • the present invention utilises the concept of CNG as a fuel for powering an engine of a watercraft, such as a ship, not as the primary fuel, but as a secondary fuel, i.e. for coastal manoeuvering, rather than primary journeys from one location to the next.
  • Type I Consists of an all metal, usually aluminum or steel, construct. This type of vessel is inexpensive but is very heavy in relation to the other classes of vessels. The entire vessel is of sufficient strength to withstand the intended pressure exerted on the vessel by a contained compressed fluid and therefore does not require any manner of strength-enhancing over-wrap, including the dry filamentous over-wrap of this invention.
  • Type I pressure vessels currently comprise a large portion of the containers used to ship compressed fluids by sea, their use in marine transport incurs very tight economic constraints.
  • Type II Consists of a thinner metal cylindrical center section with standard thickness metal end domes such that only the cylindrical portion need be reinforced, currently with a composite over-wrap.
  • the composite wrap generally constitutes glass or carbon filament impregnated with a polymer matrix.
  • the composite is usually "hoop wrapped" around the middle of the vessel.
  • the domes at one or both ends of the vessel are of sufficient strength to withstand the pressures developed in the vessel under normal use and are not composite wrapped.
  • the metal liner carries about 50% of the stress and the composite carries about 50% of the stress resulting from the internal pressure of the contained compressed fluid.
  • Type II vessels are lighter than type I vessels but are more expensive.
  • Type III Type III.
  • Consists of a thin metal liner that comprises the entire structure, that is, the cylindrical center section and the end dome(s).
  • the liner is currently reinforced with a filamentous composite wrap around entire vessel.
  • the stress in Type III vessels is shifted virtually entirely to the filamentous material of the composite wrap; the liner need only withstand a small portion of the stress.
  • Type III vessels are much lighter than type I or II vessels but are substantially more expensive.
  • Type IV Consists of a polymeric, essentially gas-tight liner that comprises both the cylindrical center section and the dome(s), all of which is currently fully wrapped with a filamentous composite. The composite wrap provides the entire strength of the vessel. Type IV vessels are by far the lightest of the four approved classes of pressure vessels but are also the most expensive.
  • Type II, III and IV pressure vessel currently require a composite overwrap over a vessel liner to give them the necessary strength to withstand the intended pressure exerted by a compressed fluid contained in the vessel. It is known, however, that the polymeric matrix of the composite wrap adds little or no strength to the overwrap.
  • this invention also can be used with novel winding arrangements using a dry filamentous material that is disposed over a pressure vessel liner in a dry state and that is remains in essentially a dry state (i.e. not bonded throughout with an impregnation of resin) for the life-time of the pressure vessel.
  • Essentially in a dry state takes into consideration that, in use, particularly for marine transport of compressed fluids, the filamentous material may inadvertently become dampened by environmental moisture and the like. That is, the dry filamentous material is intended to be disposed over the vessel dry and to be dry when the vessel is put in use. Essentially dry in this context therefore does not exclude situations where the filaments/fibres are wetted by water.
  • the pressure vessels used for the present invention will typically be type 3 or type 4, or another form of pressure vessel utilising a full composite overwrap and either a non structural metal liner or a non metal liner or a liner used purely for the process of manufacture, i.e. a removable liner. This is because they are more lightweight than the all steel type 1 pressure vessels, whereby they are more accomodatable onboard the watercraft.
  • type 3 and 4 pressure vessels new forms of pressure vessel can be applied to these various applications.
  • These pressure vessels can be referred to as type 5, type 6, and type 7 pressure vessels.
  • a type 5 pressure vessel comprises no separate liner, with the liner instead being either integral to the composite wall or it is a removable mandrel used for the forming of the wound composite wall, that mandrel then being removed after the winding process.
  • a type 6 pressure vessel has a steel cylindrical section and composite end-domes.
  • a type 7 pressure vessel has a steel liner, a composite overwrap and composite end domes.
  • Other variants can include type 4 pressure vessels with a metalic internal coating, which coating can improve the imperviousness of the pressure vessel to gases.
  • One structure for a preferred pressure vessel is a vessel having a generally cylindrical shape over a majority of its length and at least one stainless steel layer as a first layer for being in contact with the compressed fluid within the vessel, the first layer being made of low-carbon stainless steel, and the vessel further having a further external composite layer made of at least one fiber-reinforced polymer layer that will not be in contact with the fluid contained within the vessel.
  • the vessel will have an opening for gas loading and offloading.
  • a plurality of the pressure vessels can be arranged in a module or compartment, and the pressure vessels can be interconnected for loading and offloading operations.
  • the vessels all have the same height, length or diameter. Some may have different heights, lengths or diameters to allow the vessels to be custom-fitted into the space provided for them within the relevant vehicle or module or compartment.
  • Another preferred structure for the pressure vessel is a generally cylindrical shape over a majority of its length and at least one opening for gas loading and offloading and for liquid evacuation, the pressure vessel comprising a non-metallic internal coating, a metallic liner; and at least one external fiber layer.
  • the non-metallic internal coating is preferably substantially inert.

  • the fiber layer may comprise glass fibers.
  • the pressure vessel may further comprise a gas permeable layer interposed between the metallic liner and the fiber layer.
  • the gas permeable layer may comprise glass fibers.
  • the pressure vessel may further comprise a gas detector connected to the gas permeable layer for detecting a gas leakage.
  • the pressure vessel may be of essentially cylindrical shape, inside and outside, along the majority of its length.
  • Another configuration for the pressure vessel may be again a generally cylindrical shape over a majority of its length and at least one opening for gas loading and offloading.
  • the pressure vessel comprises a metallic liner, a first fiber layer external and adjacent to the metallic liner, and a second fiber layer external and adjacent to the first fiber layer.
  • the first and second fiber layers are made of different materials.
