Load profiles in the marine sector normally have engines running at maximum continuous rating for days or even weeks. Tugboats are small vessels travelling at reduced load. In the paper a hybrid drive system for a tug is outlined to realize the fuel, emissions and wear savings. The hybrid propulsion system comprises an engine, an electric motor/generator, high performance lithium ion batteries and an auxiliary diesel generator. There are two operating modes provided, a transit mode and a working mode. The drive system has been tested, a test device simulating the propulsion system was provided. Simulation and test as well as battery control test and integration control test are described in the paper. The layout and specification of the hybrid device is shown. Regulations and lithium ion battery control are described. The construction with the hybrid propulsion has been applied and shows a fuel consumption reduction of about 30 %.
