Dredge selectivity in a Mediterranean striped venus clam (Chamelea gallina) fishery
(Peer reviewed; Journal article, 2021)The striped venus clam Chamelea gallina is the target of a large fleet of hydraulic dredgers, which represent an important fishing sector in terms of income and landings in the Mediterranean Sea. Although there is information ... -
Drift of submerged oil at sea
(IKU rapporter;P 319/1, Report, 1982-10-14)The report presents results from a major study concerning dispersion of oil from a drifting slick at sea. The major emphasis is given to a discussion of the mechanisms governing the rate of dissipation of oil from the ... -
Drilling Riser Model Test for Software Verification
(Journal of Offshore Mechanics and Arctic Engineering;OMAE-17-1067, Journal article; Peer reviewed, 2017)Marine drilling riser is subject to complicated environmental loads which include top motions due to Mobile Offshore Drilling Unit (MODU), wave loads and current loads. Cyclic dynamic loads will cause severe fatigue ... -
