A Comparison of Single- and Multi-parameter Wave Criteria for Accessing Wind Turbines in Strategic Maintenance and Logistics Models for Offshore Wind Farms
(Journal article; Peer reviewed, 2014)Different vessel types for transferring technicians for maintenance and inspection of offshore wind farms are often evaluated and compared by their limiting significant wave height for accessing the wind turbines. The ... -
A genetic search-based heuristic for a fleet size and periodic routing problem with application to offshore supply planning
(Journal article; Peer reviewed, 2017-08-22)This paper introduces a genetic search-based heuristic to solve an offshore supply vessel planning problem (SVPP) faced by the Norwegian oil and gas company Statoil. The aim is to help the company in determining the optimal ... -
A Hydrodynamic Analysis of Motion Coupling Effect of Floating Storage Tank Supported by Marine Fenders
(ASME Proceedings | Ocean Space Utilization;OMAE2017-61726, Chapter, 2017-06-25)This study concerns a new concept of floating oil storage facility, to be deployed in coastal waters, in which separate oil storage tanks float in an array, separated by a mooring fender system. In this paper, hydrodynamic ... -
A Machine Vision System for Robust Sorting of Herring Fractions
(Journal article; Peer reviewed, 2016-07-16)Among the rest raw material in herring (Clupea harengus) fractions, produced during the filleting process of herring, there are high-value products such as roe and milt. As of today, there has been little or no major effort ... -
A meta-analysis of plaice size-selection data in otter trawl codends
(Journal article; Peer reviewed, 2020-07)The influence that mesh size, the number of open meshes around the circumference, twine thickness and catch size have on the size-selection of plaice (Pleuronectes platessa) in otter trawl codends is investigated by ... -
A metaheuristic solution method for optimizing vessel fleet size and mix for maintenance operations at offshore wind farms under uncertainty
(Journal article; Peer reviewed, 2017-10)Maintenance operations at offshore wind farms are challenging due to the offshore element; maintenance technicians and spare parts need to be transported from an onshore port or offshore station to the individual wind farm ... -
A model for optimal fleet composition of vessels for offshore wind farm maintenance
(Journal article; Peer reviewed, 2017)We present a discrete optimisation model that chooses an optimal fleet of vessels to support maintenance operations at Offshore Wind Farms (OFWs). The model is presented as a bi-level problem. On the first (tactical) level, ... -
