The method involves capturing the waveforms of two movement variables of a vessel. A correlation value is determined from a pair of time courses and one or multiple swell sizes. The wave form is detected by three movement variables of the vessel. Multiple ...

Combusting fuel-oxygen mixture, preferably methanol-oxygen mixture in a submarine, comprises supplying a substoichiometric fuel-oxygen mixture to a first catalyst (2a) and catalytically combusting in the catalyst, converting excess fuel into a product gas,...

The method involves supplying a hydrogen-containing reformate of a reformer partially to two membrane filters, where the reformer is operated with a fuel that comprises hydrocarbon i.e. methanol, and water. A gaseous fuel i.e. hydrogen, separated by one of...

The method involves detecting the rotating point movement of a water vehicle (x). The parameter of the rotating point movement is determined depending on the sea disturbance variables (a,Ak). One or multiple sea disturbance variables of parameter are deter...

A battery system for a submarine having at least two battery modules (BM) capable of supplying the network voltage comprises switches (8) connecting each module to the power network that can individually connect/ disconnect the modules to/from the network....

The method involves providing an electric drive with a battery for power supply. A consumption profile for travel duration and a type and duration of charging cycles of the battery up to a selected future point of time are selected. A remaining available e...

The battery monitoring system has a central evaluation device (2) for continuous detection of individual cell voltages of individual battery cells. The evaluation device can monitor the individual cell voltages of all battery cells. It is connected to at l...

The stack of fuel cells (2) generates electricity to turn the propeller to drive the submarine. Hydrogen (H2) and oxygen (O2) are fed to the fuel cells from respective storage tanks. The hydrogen may be stored in the form of metal hydrides (4) and waste he...
