8 Power Management Based on Model Predictive Control PhD Candidate: Torstein Ingebrigtsen Bø The electric power plant is a safety critical component during DP. Increasing redundancy increases the safety, but increase fuel consumption and emissions. By simulation, the safety and optimality can be evaluated. Simulation based methods will be explored for: Governors Automatic start and stop of generators Outcomes: Marine Power and Vessel Simulator Scenario Based Economic Model Predictive Control Simulation Based Unit Commitment Supervisor: Tor Arne Johansen Co-supervisors: Asgeir Sørensen & Roger Skjetne You can add pictures on the slide showing what you do
9 Nonlinear and Fault-tolerant Control of Electric Power Production in Arctic DP Vessels PhD Candidate: Andreas Reason Dahl Increased producer diversity (diesel, LNG, batteries, fuel cells) in marine power plants calls for new control methods. Load sharing by nonlinear coordinated control Fault-tolerant control on producer and plant level Outcomes: Model producers and plants Develop concepts and algorithms: load sharing fault-tolerant control Verify through simulations and in hybrid power lab Supervisor: Professor Skjetne, Roger Co-supervisor: Professor Sørensen, Asgeir Johan
10 A New Approach for Handling Risk in Dynamic Position Systems for Marine Vessels PhD Candidate: Børge Rokseth The scope of this project is to develop new methods based on dynamic models for on-line handling and control of risk associated to drift-off and drive-off for dynamically positioned vessels. This does comprise On-line hazard identification techniques On-line identification of possible worst case failures On-line analysis of consequences of worst case failures Outcomes: The outcomes of this will be a general frame work for on-line risk handling for advanced dynamic systems where the causality and interconnections between subsystems and components cannot easily be perceived by the human brain.
