Abstract
A marine vessel power generation system comprising a conventional machinery arrangement, such as an internal combustion engine (2) and a generator (3), a propulsion system, and a main switchboard (6). In order to provide an environmental friendly power generation system, when the marine vessel enters, leaves or is in port, said system is provided with an H2O operated power generation arrangement (8) for generating H2O from seawater in order to produce electrical energy.

A method of operating a marine vessel that comprises an internal combustion engine, a fuel oil storage device for supplying fuel oil to the internal combustion engine, a generator, an electrolysis device, an H2 storage device, and an H2 operated power generation apparatus, said method comprising:
- when the marine vessel is at sea, fueling the internal combustion engine with fuel oil from the fuel oil storage device, using the internal combustion engine to drive both a mechanical propulsion system and the generator, supplying electrical energy produced by the generator to the electrolysis device by way of a switchboard for producing H2 from seawater, and supplying H2 produced by electrolysis device to the H2 storage device,
- when the marine vessel enters, leaves or is in port, supplying H2 from the H2 storage device to the H2 operated power generation apparatus for producing electrical energy, and supplying electrical energy produced by the H2 operated power generation apparatus by way of the switchboard to an electrical propulsion system.
A marine vessel power generation system comprising an internal combustion engine, a fuel oil storage device for supplying fuel oil to the internal combustion engine, a generator, an electrolysis device, an H2 storage device, an H2 operated power generation apparatus, a mechanical propulsion system and an electrical propulsion system, power generation system having a first operating configuration in which the internal combustion engine is fuelled with fuel oil from the fuel oil storage device and is connected to drive both the mechanical propulsion system and the generator, the generator is connected to supply electrical energy produced by the generator to the electrolysis device by way of a switchboard for producing H2 from seawater, and the electrolysis device is connected to supply H2 produced by the electrolysis device to the H2 storage device, and a second operating configuration in which the H2 storage device is connected to supply H2 to the H2 operated power generation apparatus for producing electrical energy, and the H2 operated power generation apparatus is connected to supply electrical energy by way of the switchboard to the electrical propulsion system.
