Today's energy concepts emphasize the importance of offshore-wind energy as a vital element for environmental friendly, reliable and affordable power supply. The electric power generation on the deep sea is supposed to contribute remarkably to the coverage of the total energy consumption. Successful installation of such systems requires well trained engineers with great special knowledge and specific nautical abilities. Maritime trade represents a key cornerstone in the globalization of freight traffic. In this, container shipping is occupying an important part. The provision of electric energy on such large vessels presents a big challenge for the power supply, which has to function reliably and safely. ept Services Marine & Offshore GmbH offers services and solutions in both maritime fields.
