PhD - Simulation Based Design of Ships With Regards to System Performance

Research topics

The purpose of the PhD research is to provide knowledge regarding the validity of simulation models for application in ship design. The research will focus on how simulation is applied to virtually test designs in realistic conditions and operational scenarios. This includes benchmarking of simulation results and full-scale measurements to reveal important factors that influence the quality of simulation estimates.

Industrial goal

Knowledge that supports energy efficient design and operation of ships using simulation-based methods. The current research focuses on resistance, propulsion and fuel consumption of deep-sea vessels in transit.

Achievements

A validation study towards estimation of fuel consumption and operational profile using GYMIR was conducted in the last quarter of 2017. The methodology and results are presented in a conference paper submitted to the International Marine Design Conference in Helsinki June 2018. Further validation studies of the GYMIR workbench will be performed in 2018. 

Currently finishing two papers to be submitted for review this year:
1. Ship sea passage model for operational scenario generation in simulation-based design. Endre Sandvik, Jørgen Bremnes Nielsen, Bjørn Egil Asbjørnslett, Eilif Pedersen, Kjetil Fagerholt
2. Impact of simulation model fidelity on ship system evaluation in sea passage scenarios. Jørgen Bremnes Nielsen, Endre Sandvik, Bjørn Egil Asbjørnslett, Eilif Pedersen, Kjetil Fagerholt


Plan for remaining PhD project period

The project funding ends in May 2019. The remaining period is devoted to writing the PhD thesis.
