摘要:
A double-walled liquefied gas tank characterized in that one or more insulation spaces about the vat containing the liquid are filled with a mixture, consisting mainly of argon trapped by gravity, between the outer walls of the vat and: a) for the insulating space (2) located below the bottom wall of the vat, the base plate (3) supporting the vat; b) for the insulating spaces (5) and (6), the circular chamber (16); c) for the insulation spaces (7) and (25), the circular chamber (16) and the roof (17); d) for the insulation space (14), the suspended and sealed ceiling (12), respectively.
摘要:
Connection device (1) designed to connect, particularly a ship in a port, includes a connector (2), a carriage (3) forming a housing (17) for the connector when it is not connected, and a runway track (4) on which to move the carriage, the connector being designed to be connected by cable (30) to a land-based network. Such a device ensures that the correct positioning of the ship relative to the connector can be guaranteed.
摘要:
An electrical connection assembly between a movable object and a fixed installation, the assembly including the following elements of substantially cylindrical shape, centered around a vertical axis and going downwards: a windlass using a chain to move a rod along the axis; an outlet receiving a plurality of connections and provided with a hawse pipe in which the rod can engage with small clearance; a connector provided with a top endplate receiving, facing the connections of the outlet, the complementary connections; a turnable lid protecting the connections; a guide and locking system for guiding and locking the rod; and having its bottom portion of conical shape; a rod passing downwards in succession through the hawse pipe of the outlet, then the lid, in order to reach a locking system for locking with the connector; and a basket of funnel-shape, with its large opening upwards, its shape being complementary to the bottom portion of the connector, and centering the connector on the axis.
摘要:
A ship that is to be coupled electrically to a terminal a method, and a method and a device for connecting an electrical power line (1) between a ship (3) and a terminal (5). The device includes an unwinder (7) for unwinding a traction cable (13) from the ship (3) towards a connection end (15) of the electrical power line (1); a lashing device (9) for lashing the traction cable (13) to the connection end (15); and a traction device (11) for pulling the electrical power line towards the ship (3) so as to connect the connection end (15) with an electrical interface (17a) of the ship (3).
摘要:
A device and a method for powering a berthed ship. The powering device includes an onboard connector, a shuttle (40), a traction element (41) for the shuttle, which includes elements for engaging with a ground connector (30) matching the onboard connector, the traction element being provided for pulling the shuttle and the ground connector when they are engaged such that the ground connector is in electrical continuity with the onboard connector. The device can be used for powering a ship without running the onboard generators thereof. For methane tankers in particular, the device can be used for supplying electricity to the grid by burning the gas vapors. The device can be automated, thereby avoiding fatigue and electrical risks.
