Background and activities

Professor in Marine Control Engineering from August 2009. Research projects: Arctic Dynamic Positioning; Ice surveillance; Power Management Systems.

Chair in marine control engineering

The chair held by Professor Roger Skjetne in marine control engineering will focus on three fields. The first is dynamic positioning of marine vessels, which means to develop energy-optimal systems to make ships automatically and safely keep position and heading, even under the influence of wind, currents, waves, and ice, and also when exposed to relevant system and component failures. This is essential for supply ships and drill rigs to safely operate in deep waters in Arctic areas.


The other field is management control systems for electric power generation and distribution onboard ships. This is important to to reach the goal of safe and environmentally robust marine electrical power systems, to avoid blackouts, and on longer term for the vision of zero emissions from ships.

The third field is motion control of marine vessels, both in controlling single vessels and formations of vessels. For instance, it could be automatic control of several unmanned subsea vessels, and how they behave in relation to each other when mapping the bottom of the sea and in coordinated movement with a vessel on the surface. It may also be used to control formations of unmanned aircrafts that monitor the environment and ice conditions in the Arctics.

Fields of interest:

  • Autonomous control of marine vessels under influence of environmental loads.
  • Dynamic positioning control systems.
  • Control of shipboard hybrid electric power systems.
  • Arctic stationkeeping and Ice Management systems, incl. ice surveillance.
  • Hybrid experimental- and simulation-based model testing.
