摘要:
The invention relates to an energy system using as fuel natural gas stored in liquid form in at least one tank containing liquefied natural gas, the system comprising a feeder device provided with a heater device for heating liquefied natural gas and/or natural gas vapor, and making use of a thermoelectric power unit including rotary electrical machines, the system further comprises a first heat exchanger system associated with a cooler device for cooling the rotary electrical machines, and a second heat exchanger system associated with the heater device, the first heat exchanger system being coupled to the second heat exchanger in order to enable heat to be transferred from the cooler device to the heater device.

摘要:
A propulsion chain (8) for a ship (6) including a main heat engine (18); at least one secondary electrical power house (26) powering a distribution panel (34); at least one transmission line (16) provided with an end propeller (14) and mechanically coupled to the main heat engine (18) to drive the latter; at least one rotating electrical machine (22) mechanically coupled to the transmission line (16) and powered from the distribution panel (34), a mechanical coupler (20) able to be freed from the main heat engine (18) and the rotating electrical machine (22) arranged on the transmission line (16), between the rotating electrical machine (22) and the main heat engine (18). A synchronizer (60) for synchronizing the speeds of the rotating electrical machine (22) and the main heat engine (18) before coupling of the rotating electrical machine (22) and the main heat engine (18), and an engager for engaging the mechanical coupler when the speeds of the rotating electrical machine (22) and the main heat engine (18) are essentially equal, i.e. correspond.
