Supervisory Control of Line Breakage for Thruster-Assisted Position Mooring System 

Ren, Zhengru; Skjetne, Roger; Hassani, Vahid (Chapter; Conference object; Peer reviewed, 2015)
Thruster-assisted position mooring (TAPM) is an energy-efficient and reliable stationkeeping method for deep water structures. Mooring line breakage can significantly influence the control system, and ultimately reduce ...

A Tension-based Position Estimation Approach for Moored Marine Vessels 

Ren, Zhengru; Skjetne, Roger; Kjerstad, Øivind Kåre (10th IFAC Conference on Manoeuvring and Control of Marine Craft;MCMC 2015, Conference object; Journal article; Peer reviewed, 2015)
This paper presents a novel idea on a tension-based localization approach as a redundancy measure to handle the situation when the position reference (posref) signals are not available or significant GNSS drifts occur, ...

Framework for Product-Mix and Changeover Manufacturing Flexibility 

Wadhwa, Rhythm Suren (Journal article; Peer reviewed, 2014)
Facing new challenges and more uncertainty, manufacturers see the need for flexible solutions and the need to strive to achieve flexibility. However, flexibility is still not well understood and no unambiguous understanding ...

Assessing Climate Change Impacts on Global Hydropower 

Hamududu, Byman; Killingtveit, Ånund (Journal article; Peer reviewed, 2012)
Currently, hydropower accounts for close to 16% of the world’s total power supply and is the world’s most dominant (86%) source of renewable electrical energy. The key resource for hydropower generation is runoff, which ...

Online reconstruction of drifting underwater ice topography: The 2D case 

Jørgensen, Ulrik; Skjetne, Roger (Journal article; Peer reviewed, 2015)
An online estimation design for a drifting two dimensional ice topography is presented. Under the assumption that the topography can be accurately represented by a truncated Fourier series, and given a moving window of ...

A reference pelton turbine - design and efficiency measurements 

Solemslie, Bjørn Winther; Dahlhaug, Ole Gunnar (Journal article; Peer reviewed, 2014)
The Pelton turbine has been subject to a varying degree of research interest since the debut of the technology over a century ago. Despite its age there are gaps in the knowledge concerning the flow mechanisms effecting ...

Control of Upper Limb Prostheses: Terminology and Proportional Myoelectric Control-A Review 

Fougner, Anders Lyngvi; Stavdahl, Øyvind; Kyberd, Peter Joseph; Losier, Yves G.; Parker, Philip A. (Journal article; Peer reviewed, 2012)
The recent introduction of novel multifunction hands as well as new control paradigms increase the demand for advanced prosthetic control systems. In this context, an unambiguous terminology and a good understanding of the ...

Verification and Examination Management of Complex Systems 

Ruud, Stian Knud; Skjetne, Roger (Journal article; Peer reviewed, 2014)
As ship systems become more complex, with an increasing number of safety-critical functions, many interconnected subsystems, tight integration to other systems, and a large amount of potential failure modes, several industry ...

Autonomous Aerial Ice Observation for Ice Defense 

Haugen, Joakim; Imsland, Lars Struen (Journal article; Peer reviewed, 2014)
One of the tasks in ice defense is to gather information about the surrounding ice environment using various sensor platforms. In this manuscript we identify two monitoring tasks known in literature, namely dynamic coverage ...

Experimental and Numerical Investigation of a Double-Acting Offshore Vessel Performance in Level Ice 

Su, Biao; Skjetne, Roger; Berg, Tor Einar (Journal article; Peer reviewed, 2014)
In this paper a numerical model and experimental data are used to investigate the level ice performance of a double-acting intervention vessel. The icebreaking capability and maneuverability in level ice are analyzed by ...
