About BEM Marine Power
BEM Marine Power GmbH was founded in 2015 by Yanqing Qu and develops and manufactures high-performance electric drive and generator technology. The portfolio includes three-phase generators (alternators) of the L-series (GL05–GL12, 400–9000 kVA, 400–690 V) and H-series (GH10–GH100, 500–25000 kVA, 3.3–15 kV) as well as electric motors of the ML and MH series (200–4000 kW) as asynchronous or permanent-magnet motors for main propulsion, bow thrusters and auxiliary operation. In addition, switchgear cabinets, high-voltage frequency converters and DC generators are offered. Production takes place at the Wuxi production site (China); development, simulation and custom design are based in Hamburg. Materials and components include, among others, copper squirrel-cage rotor bars and thermal class H/F insulation systems. The products are manufactured to IEC/EN 60034, BS 5000 and VDE 0530 and are accepted by classification societies such as DNV, LR, ABS, BV, CCS and RINA. Fields of application include shipping, offshore, power plants/CHP, oil & gas and the cement industry.
