Comparison of Fuel Consumption on a Hybrid Marine Power Plant With Low-Power Versus High-Power Engines
Wu, Zhenying; Thorat, Laxminarayan; Skjetne, Roger (Chapter, 2018)In this paper, we are comparing fuel consumption on a case study hybrid marine power plant with diesel gensets and batteries. Optimization methods are used to find an optimal operating point for the gensets, under different ... -
Genset scheduling in a redundant electric power system for an offshore vessel using mixed integer linear programming
Thorat, Laxminarayan; Skjetne, Roger; Osen, Ottar (Journal article, 2021)This paper proposes several schemes for optimal scheduling of power producers in a shipboard power system for a typical offshore supply vessel, having a multiple number of possibly varying capacity gensets. The proposed ... -
Marine Vessel and Power Plant System Simulator
Bø, Torstein Ingebrigtsen; Dahl, Andreas Reason; Johansen, Tor Arne; Mathiesen, Eirik; Rejani Miyazaki, Michel; Pedersen, Eilif; Skjetne, Roger; Sørensen, Asgeir Johan; Thorat, Laxminarayan; Yum, Kevin K. (Journal article; Peer reviewed, 2015)Modern marine electric propulsion vessels have many systems. These interactions and integration aspects are essential when studying a system and subsystem behavior. This is especially important when considering fault ... -
Model Predictive Control of Marine Vessel Power System by Use of Structure Preserving Model
Dahl, Andreas Reason; Thorat, Laxminarayan; Skjetne, Roger (Journal article; Peer reviewed, 2018)The paper presents model predictive control (MPC) based on an optimization model drawn from the structure preserving model (SPM) for marine vessel power systems. Three objective functions are proposed to control frequency, ... -
Optimal Online Configuration and Load-Sharing in a Redundant Electric Power System for an Offshore Vessel Using Mixed Integer Linear Programming
Thorat, Laxminarayan; Skjetne, Roger (Chapter, 2018)This paper proposes several schemes for optimal online configuration and load sharing for a shipboard power system of a typical offshore vessel, having a number of varying capacity gensets. Different methods are presented ... -
Optimal Scheduling and Loadsharing of a Hybrid Power Plant with Gensets and Battery Banks
Lu, Ying (Master thesis, 2019)The increased power demand of shipboard electrical power system has produced considerable environmental pollution such as heavy fuel consumption and the emission of CO2 and NOx. In response to the degradation in the global ... -
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, ...
