Dynamic Response Analysis of Floating Storage Tank System Considering Hydrodynamic and Mechanical Interactions
(Chapter, 2018-06-25)For better utilization of ocean and coastal space, hydrocarbon products can be stored in the floating tanks, which can be enclosed by barge system. The barge system can be moored through pile foundations. The tanks are ... -
Dynamic response of a monopile wind turbine in waves: Experimental uncertainty analysis for validation of numerical tools
(Journal article; Peer reviewed, 2019-05-23)The responses of a monopile offshore wind turbine subjected to irregular wave loads are investigated numerically and experimentally, considering a range of sea states. An extensive experimental campaign was carried out on ... -
Dynamic response of a top-tensioned riser under vessel motion
(Journal article; Peer reviewed, 2018-07)Model tests of a top-tensioned riser model were carried out as a part of a joint industry project, with the purpose of verifying the calculations of the riser analysis program RIFLEX. Sinusoidal motion in one direction was ... -
Dynamic responses of a jacket-type offshore wind turbine using decoupled and coupled models
(ASME Proceedings | Ocean Renewable Energy;OMAE2014-24246, Chapter, 2014-06)This paper presents numerical studies of the dynamic responses of a jacket-type offshore wind turbine using both decoupled and coupled models. In the decoupled (hydroelastic) model, the wind load is included through ... -
Dynamic responses to silicon in Thalassiosira pseudonana - Identification, characterisation and classification of signature genes and their corresponding protein motifs
(Journal article; Peer reviewed, 2017-07-07)The diatom cell wall, or frustule, is a highly complex, three-dimensional structure consisting of nanopatterned silica as well as proteins and other organic components. While some key components have been identified, ... -
An economic analysis of introducing autonomous ships in a short‐sea liner shipping network
(Journal article; Peer reviewed, 2020-03-16)The development of autonomous ships is at an advanced stage. It seems to be just a question of time before such ships become available at an industrial scale. In this paper, we investigate the economic advantages of utilizing ... -
Economic savings linked to future Arctic shipping are at odds with climate change mitigation
(Journal article; Peer reviewed, 2016)This paper assesses costs, emissions, and climate impact by freight shipping in the Arctic with main focus on the Northern Sea Route. The entire route lies in Arctic waters, which due to global warming, has become ice free ... -
Ecotoxicological effects of transformed silver and titanium dioxide nanoparticles in the effluent from a lab-scale wastewater treatment system
(Journal article; Peer reviewed, 2018-07-26)In this study, a lab-scale wastewater treatment plant (WWTP), simulating biological treatment, received 10 μg/L Ag and 100 μg/L TiO2 nanoparticles (NPs) for 5 weeks. NP partitioning was evaluated by size fractionation (>0.7 ... -

Effect of a lateral square-mesh panel on the catch pattern and catch efficiency in a Mediterranean bottom trawl fishery
(Journal article; Peer reviewed, 2020)The current legal codends used in Mediterranean bottom trawl fisheries are at high risk of retaining undersized individuals of several commercial fish species. This entails that codends alone are unable to provide the ... -
Effect of a quality-improving codend on size selectivity and catch patterns of cod in bottom trawl fishery
(Journal article; Peer reviewed, 2019-02-26)A new codend concept developed and tested exhibited significantly improved quality of caught cod (Gadus morhua) compared to that of the conventional codend used in the Barents Sea bottom trawl fishery. However, the design ... -
