The method involves guiding a coolant in a coolant circuit by the heat-generating device, such that a partial stream of coolant is derived from the coolant circuit in a liquid deaerator (10) and then returned to the coolant circuit. The supply of partial s...

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,...

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...
