The company

E-MS, e-powered marine solutions GmbH & Co. KG is a privately owned design and development office for electrical engineering for ships and offshore facilities.


E-MS, e-powered marine solutions GmbH & Co. KG is an independent development and design company for electric power generation and propulsion systems for ships and offshore applications. The company was founded in 2005 by Dipl.-Ing. Peter Andersen in Bremen and is today a limited partnership with Andersen as managing partner and headquarters in Hamburg.

Peter Andersen’s background are more than 20 years of experience in diesel, otto and hybrid drive technology and on board power supply systems gained with Siemens Marine Solutions. Thus, he is familiar with the different requirements of ship power plants on board of all kinds of cargo vessels, multi-purpose and offshore support vessels, research and fishery vessels as well as mega yachts and river cruise vessels.

Based on the tremendous progress in power electronics in the 1990 years Andersen developed a unique topology for electric power generation and distribution on board of ships, including an electric propulsion system. With this technology, patented to him, it was possible to refrain from synchronizing multiple generators, thus saving a lot of space as well as weight in the engine and control rooms.

The small international operating team of E-MS is a significant partner of shipping companies, shipyards and naval architects, with own project development. The company has been the first worldwide to develop and implement an extreme efficient diesel-electric power supply and propulsion system with a common DC-Bus. This system has been installed for the first time on board the river cruise vessel “Viking Legend” built by the SET yard at Tangermünde in 2009. This advanced concept has been awarded in 2011 with the “River Cruise Innovation Award” and has since been implemented on more than 40 vessels operated by Viking River Cruises.

“Power supply concepts for propulsion and ship’s network from design upon till putting into operation.”

There is a close cooperation between E-MS and well-known manufacturers of power converters and electric machines. These are international cooperations, which guarantee that only components with ensured quality will be integrated in technical solutions developed by E-MS. The company offers standard solutions as well as special concepts, finely tuned to the technical requirements of the customers including conception, planning, projection, engineering, programming and commissioning will be carried out by well-trained engineers and service specialists.
