Dispersal and Deposition of Detritus From Kelp Cultivation
(Peer reviewed; Journal article, 2022)A high resolution coastal and ocean hydrodynamic model system was used to investigate the transport and deposition patterns of Particulate Organic Matter (POM) from kelp farmed at three locations of different properties: ... -
Dispersibility and biotransformation of oils with different properties in seawater
(Journal article; Peer reviewed, 2018-01)Dispersants are used to remove oils slicks from sea surfaces and to generate small oil-droplet dispersions, which may result in enhanced biodegradation of the oil. In this study, dispersibility and biodegradation of ... -
Dispersibility and dispersion stability of carbon nanotubes in synthetic aquatic growth media and natural freshwater
(Journal article; Peer reviewed, 2018-06)The dispersion behavior of carbon nanotubes (CNTs) is influenced by both their physicochemical properties and by the aqueous media properties (e.g. ionic strength, presence of divalent cations and natural organic matter) ... -
Distributed Co-Simulation of Maritime Systems and Operations
(ASME digital collection;OMAE-17-1037, Journal article; Peer reviewed, 2018-05)Here, we present the concept of an open virtual prototyping framework (VPF) for maritime systems and operations that enables its users to develop reusable component or subsystem models, and combine them in full-system ... -
A distributed object-oriented simulator framework for marine power plants with weak power grids
(Peer reviewed; Journal article, 2022)In this work, we discuss and demonstrate how multi-engine marine power plants with weak power grids efficiently can be set up and simulated in a distributed co-simulation framework. To facilitate configuration switching ... -

Drag Forces and deformation of aquaculture cages – full-scale towing tests in the field
(Journal article; Peer reviewed, 2018-02-23)Fish cages can experience strong loads due to hydrodynamic forces in the sea. Numerical models are often used to estimate drag forces on net cages, and the development and validation of such models is mostly based on ... -
Drag of Clean and Fouled Net Panels – Measurements and Parameterization of Fouling
(Journal article; Peer reviewed, 2015-07-07)Biofouling is a serious problem in marine aquaculture and it has a number of negative impacts including increased forces on aquaculture structures and reduced water exchange across nets. This in turn affects the behavior ... -
Drag on Nets Fouled With Blue Mussel (Mytilus Edulis) and Sugar Kelp (Saccharina Latissima) and Parameterization of Fouling
(ASME Digital colletion;OMAE2017-62030, Chapter, 2017-06-25)Biofouling is a serious problem in marine finfish aquaculture with a number of negative impacts. Marine growth obstructs net openings, thereby reducing water exchange through the net and affecting fish welfare and health, ... -

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 ... -
