    • Dynamics of a Marine Propulsion System With a Diesel Engine and a Propeller Subject To Waves 

      Taskar, Bhushan; Yum, Koosup; Pedersen, Eilif; Steen, Sverre (Chapter; Peer reviewed, 2015)
      When travelling in waves, the efficiency of the propulsion system is in most cases reduced, due to a variety of different effects. Traditionally, the performance of propeller and engine is analyzed separately. However, ...

    • Hybrid modeling of strategic loading of a marine hybrid power plant with experimental validation 

      Rejani Miyazaki, Michel; Sørensen, Asgeir Johan; Lefebvre, Nicolas; Yum, Koosup; Pedersen, Eilif (Journal article; Peer reviewed, 2016)
      Recent developments in marine power systems, energy storage devices (ESDs) technology, and modification to rules and regulations increase the opportunities to improve efficiency and reduce emissions. One particular application ...

    • Real-Time Marine Vessel and Power Plant Simulation 

      Bø, Torstein Ingebrigtsen; Johansen, Tor Arne; Dahl, Andreas Reason; Rejani Miyazaki, Michel; Pedersen, Eilif; Rokseth, Børge; Skjetne, Roger; Sørensen, Asgeir Johan; Thorat, Laxminarayan; Utne, Ingrid Bouwer; Yum, Koosup; Mathiesen, Eirik (Chapter; Peer reviewed, 2015)
      In this paper, we present a system simulator of a marine vessel and power plant which contains the mechanical system with diesel engines, propellers, steering gear, and thrusters; the electrical system with generators, ...

    • Simulation of a two-stroke diesel engine for propulsion in waves 

      Yum, Koosup; Taskar, Bhushan; Pedersen, Eilif; Steen, Sverre (Journal article; Peer reviewed, 2016)
      Propulsion in waves is a complex physical process that involves interactions between a hull, a propeller, a shaft and a prime mover which is often a diesel engine. Among the relevant components, the diesel engine plays an ...

    • The effect of waves on engine-propeller dynamics and propulsion performance of ships 

      Taskar, Bhushan; Yum, Koosup; Steen, Sverre; Pedersen, Eilif (Journal article, 2016)
      This paper investigates the effect of waves on the propulsion system of a ship. In order to study the propulsion in different wave conditions, a procedure for wake estimation in waves has been implemented. A clear drop in ...
