OMAE2017-61768 VIV Responses of Riser With Buoyancy Elements: Forced Motion Test and Numerical Prediction
(ASME Proceedings | Prof. Carl Martin Larsen and Dr. Owen Oakley Honoring Symposia on CFD and VIV;OMAE2017-61768, Chapter, 2017-06-25)Steel Lazy Wave Riser (SLWR) is an attractive deep water riser concept. When subjected to vortex induced vibrations (VIV), the vortex shedding process of the buoyancy element and the bare riser section will be different ... -
OMAE2017-62056 Effective Power and Speed Loss of Underwater Vehicles in Close Proximity to Regular Waves
(ASME digital collection;OMAE2017-62056, Chapter, 2017-06-30)The present study is focused on performance issues of underwater vehicles near the free surface and gives insight into the analysis of a speed loss in regular deep water waves. Predictions of the speed loss are based on ... -
Omega-3 and alpha-tocopherol provide more protection against contaminants in novel feeds for Atlantic salmon (Salmo salar L.) than omega-6 and gamma tocopherol
(Journal article; Peer reviewed, 2016)Extended use of plant ingredients in Atlantic salmon farming has increased the need for knowledge on the effects of new nutrients and contaminants in plant based feeds on fish health and nutrient-contaminant interactions. ... -
On Common Research Needs for the Next Generation of Floating Support Structures
(Chapter; Peer reviewed, 2022)The world is facing several industrial and societal challenges, such as providing enough renewable energy and enough safe and healthy food as formulated in the United Nations sustainable development goals. Using floating ... -
On the Design Considerations of New Offloading Hose Applied on a Turret Moored FPSO
(ASME Digital collection;OMAE2017-61410, Chapter, 2017-06)Offloading hoses are used to transfer crude oil or liquid petroleum products from a fixed offshore production platform/floating production, storage and offloading (FPSO) unit to shuttle tankers. The hoses are subjected to ... -
On the effect of co2 on seismic and ultrasonic properties: A novel shale experiment
(Peer reviewed; Journal article, 2021)Carbon capture and storage (CCS) by geological sequestration comprises a permeable formation (reservoir) for CO2 storage topped by an impermeable formation (caprock). Time-lapse (4D) seismic is used to map CO2 movement in ... -
On the numerical stability in dynamical distributed simulations
(Journal article; Peer reviewed, 2019-09)This work takes aim at studying numerical stability in distributed simulations through dynamic stabilityand stability criteria for explicit solvers. This is done by studying outer stability limits, for example stabilityconditions ... -
On the significance of the higher-order stress in riser vortex-induced vibrations responses
(Journal article; Peer reviewed, 2019-02)Vortex-induced vibrations (VIV) can lead to fast accumulation of fatigue damage and increased drag loads for slender marine structures. VIV responses mainly occur at the vortex shedding frequency, while higher harmonics ... -
On the use of random walk schemes in oil spill modelling
(Journal article; Peer reviewed, 2019-09)In oil spill models, vertical mixing due to turbulence is commonly modelled by random walk. If the eddy diffusivity varies with depth, failing to take the derivative of the diffusivity into account in the random walk scheme ... -
On two speed optimization problems for ships that sail in and out of emission control areas
(Journal article; Peer reviewed, 2015)This paper deals with two speed optimization problems for ships that sail in and out of Emission Control Areas (ECAs) with strict limits on sulfur emissions. For ships crossing in and out of ECAs, such as deep-sea vessels, ... -
