The invention relates to an electric energy supply system for a ship, in particular for a navy ship that can be operated with a low IR signature and that is configured as an > (AES). Said system comprises a direct current network (DC), supplied by fuel cells, as a ship electrical system and network for normal propulsion and an alternating current network (AC) comprising generators, in particular for generating energy for high-speed propulsion. According to the invention, the generators are motor-driven, e.g. by means of at least one gas turbine or one diesel motor, preferably supercharged and the AC and DC network are interconnected in such a way that electric energy can be exchanged between them, in particular that electric energy can be withdrawn from the DC network and transferred to the AC network to start the motor-driven propulsion.

The invention relates to a merchant navy vessel comprising a hull which is provided for accommodating goods and/or people and which comprises at least one rotating rudder propeller that serves as a drive unit. The rotating rudder propeller is arranged in the stern of the hull, preferably in a box-type connecting unit, and the necessary components for controlling the rudder propeller are situated in the hull. The rudder propeller comprises an electric propeller motor and the electrical and mechanical components for supplying power and for controlling the rudder propeller and the electric motor thereof are combined, in part, to form functional modules. Said functional modules are configured as transport containers (1), especially as standard containers, are designed such that they can be completely tested with regard to functionality at the site of production and such that they can be inspected and approved by classification societies, and can be assembled in this form at any assembly location of the vessel using the container floor structure.

A casting device for metal strips comprises two rollers for continuous casting which between them form a slit and are provided with a water-cooled copper mantel on which a deposit builds up in the form of solidified flakes from the liquid metal (preferably steel) passing between the rollers; the flakes are compressed in the slit to form a strip and the cooled copper mantel (1) on the rollers has a wear-protection layer (4) made up of wear-resistant grains (5) or lamellae in a binder, in particular of metal, e.g. a nickel-cobalt alloy.

In a method for operation of a hybrid propulsion system (1) for a marine vessel, in particular a navy vessel, having at least one electric motor (2) and at least one internal combustion engine (3), in particular a gas turbine, as drive units, which, depending on the requirement, for example the vessel speed, individually or jointly drive at least one propulsion unit (4), for example a propeller, of the marine vessel, the respective power outputs of the propulsion units (2, 3) to the at least one propulsion unit (4) are, according to the invention, controlled by a control device (15) as a function of a predeterminable set value (S), for example a set value for the propeller rotation speed or the vessel speed, and a predeterminable operating mode (B) such that the sum of these power outputs results in a total power (PS), which is dependent on the set value, being output to the at least one propulsion unit (4), with this total power output being split between the power outputs (PE, PG) of the individual drive units (4) as a function of the set value (S) and the operating mode (B).

The invention relates to a method for the, in particular, efficiency-increasing discharging of exhaust gases of internal combustion engines of boats into the water surrounding the boats. The invention is characterized in that the exhaust gases and a flow of water drawn from the surrounding water are mixed together in a low air pressure field, the low pressure of the low pressure field being produced by a reduction in the cross-section of the flow of water before mixing ensues.

The invention relates to an electric energy supply system for a ship, in particular for a navy ship that can be operated with a low IR signature and that is configured as an «all-electric ship» (AES). Said system comprises a direct current network (DC), supplied by fuel cells (1, 2, 3, 4), as a ship electrical system and network for normal propulsion and an alternating current network (AC) comprising generators, in particular for generating energy for high-speed propulsion. According to the invention, the generators (10) are motor-driven, e.g. by means of at least one gas turbine (11) or one diesel motor, preferably supercharged and the AC and DC network are interconnected in such a way that electric energy can be exchanged between them, in particular that electric energy can be withdrawn from the DC network and transferred to the AC network to start the motor-driven propulsion.
摘要:
In the continuous casting and rolling plant and associated control system proposed, the design of the individual plant elements is optimized with respect to their combined action and the individual plant elements operated in coordinated fashion to produce steel strip which is suitable for further processing. This coordination is preferably optimized using a neurofuzzy system.
