  • the safety valve 20, the pressure sensor 21, the temperature sensor 22 and the condensate detection sensor 23 are also placed on tanks 16 and condensate pipe connections 24 are mounted in the bottom of tanks 16, where shut-off valves 25 are located.
  • containers 15 are standard shipboard 40 feet containers having external dimensions as follows: length of 12 192 mm, width of 2438 mm and height of 2591 mm. Such containers are suitable for further transportation by shallow-draft vessels on the rivers as well as by road and railway transport, but one may use other standard containers of new sizes.
  • Tanks 16 of containers 15 are connected through their shut-off valve 19 by the flexible pipeline 26 with the manifold 12, which consists of vertically oriented pipes 27 with shut-off valves 28. Pipes 27 are interconnected by a locking pipeline 29 with shut-off valves 30.
  • the manifold which is placed between the tiers in the cells, allows reducing the length of pipes and simplifying maintenance and management of gas loading system.
  • the manifold system 12 also includes the pipeline 31, which is connected through the shut-off valve 32 to manifold pipes 12 and through the shut-off valve 33 to the compressor and, as a result, through the connecting device 44 to external storage facilities.
  • Manifold pipes 12 are connected through shut-off valves 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, to the connection unit 44 and to the pipeline of external gas storage.
  • the shut-off valve 45 and the gas meter 46 are also installed.
  • the manifold pipe system of each cells pair 2 is connected to the connecting pipeline 47 laid on the upper deck with shut-off valves 48.
  • Each double-jointed cell 2 mentioned in the described manifold system 12, has the compressor 49, which is connected to the pipe 31 through the shut-off valve 36 and the pipe 27 through the shut-off valve 35 and the safety valve 50.
  • the compressor 49 is bypassed by the pipeline with shut-off valves 38, 37, 34, 39, 40, 49, and by shut-off valves 36 and 35 at its inlet and outlet.
  • connection unit 44 and the compressor 49 are installed in the hermetic stowed position and in the intensively ventilated area 51, which is established at the level of the upper deck in the area of the manifolds 12 location, in each double-jointed cell 2 along the length of the ship.
  • Cells 11 are not connected to the general compressed gas loading system and are used for other gases that are by-products, such as helium, while the main gas for transportation is methane.
  • Each double-jointed cell 2 has two containers 52 with the empty dump tank 53, with the ability to drain condensate or gas excess in the cargo tanks 16 into it, providing that dump tanks 53 are connected through their safety valves 54 and pipelines are brought out to the upper deck to the gas combustion device 55.
  • the condensate collector and drain system includes shut-off valves 25, mounted in the lower part of containers 16, which are connected through flexible pipelines 56 and shut-off valves 57 with vertical pipes 58, interconnected by switchers 59 with each other and connected to the separate pump 60.
  • the hatch cover availability makes possible to use the vessel according to the invention, both in gas uploading and offloading mode through the gas loading shipboard system or to load it with containers filled with gas tanks or offload filled containers at the container terminal and deliver gas by other means of transport.
  • deckhead cladding panels can be provided at the deckhouse 61 that are installed at the coaming, welded and contain constructive elements that can be cut in case of repair and access to some cell.
  • shut-off valves and manifold outlet pipelines 12 are covered with heat-carrying medium.
  • the system is not shown herein, as it is known to the experts and is not the subject of the invention.
  • Rotatable container locks allow loading spreader at the container terminal to install automatically or unload containers from the ship.
  • Fixing container 15 by centering cones and ties are more suitable for gas uploading and offloading through the shipboard system.
  • Gas uploading and offloading is produced both by gravity and by compressor gas supply according to the differential pressure.
  • Receiving devices 44 are connected to the gas storage outer pipeline at the production field, and as empty tanks 16 are under residual pressure of 1 kg/cm 2 gas is taken from the external gas storage under pressure above 100 kg/cm 2 through the open shut-off valves 41, 38, 37, 34 and manifolds 12 of each cell 2, and gas enters from manifolds 12 through the open shut-off valves 28 and 19 to tanks 16 of containers 15. In this case shut-off valves 48, 42, 43, 40, 36, 35, 33, 32 are closed.
  • shut-off valves 42 and 48 are opened additionally and gas is supplied into other double-jointed cell 2, in which the shut-off valve 38 is closed and gas enters the tank 16 through the shut-off valve 42 and other ones above mentioned for the first cell (see Fig. 5 , which shows a part of the loading system of another double-jointed cell 2).
  • shut-off valves 42, 38 and 37 are closing in the cells loading system, which is connected to the external pipeline by the unit 44, and shut-off valves 39, 40, 36, 35 are opening and gas is supplied by the compressor 49 and continues to flow until reaching the specified pressure in tanks 16.
  • the compressor 49 is off
  • shut-off valves 40, 36 are closing
  • shut-off valves 39, 43 are opening and gas is supplied to tanks of the double-jointed cell on the left, and if it is required to supply gas to the right (see Figure 5 ), then the shut-off valve 48 is opening.
  • shut-off valves 43, 40, 36, compressor 49 of this cell and shut-off valves 35 and 34 which are described above, manifold valves 12 are similar to the Figure .5 .
  • junction points with the pipes of the manifold 12 are denoted with letters A and B.
  • shut-off valve 45 is opening and gas counter 46 starts to work, but pressure control enables to estimate gas quantity without the counter.
  • the system allows redistributing gas between tanks in case of incomplete vessel loading and tanks being in emergency state in any of the cells.
  • Condensate can be removed from the tanks by using the gas pressure in tanks both before gas uploading and on the beginning of uploading or by the additional pump 60.
  • shut-off valves in order to explain the vessel's design and schemes of the loading, control and storage system for transportation of compressed gas, without specifying the type and the drive, but the latter is a well known electrical, hydraulic and pneumatic remote control of all types of valves in engineering, which is not described in the claim, as it is not the subject of invention.
  • Specialists and engineers of automation control are able to develop remote control systems of shut-off valves and compressors using programmable controllers connected to sensors of pressure, temperature and by switching on the operation modes for specified programs.
