CFD Investigation on Hydrodynamic Resistance of a Novel Subsea Shuttle Tanker
(Peer reviewed; Journal article, 2021-12)The Subsea Shuttle Tanker (SST) was proposed by Equinor as an alternative to subsea pipelines and surface tankers for the transportation of liquid carbon dioxide (CO2) from existing offshore/land facilities to marginal ... -
Fatigue strength degradation of metals in corrosive environments
(Journal article; Peer reviewed, 2017)Structures exposed to aggressive environmental conditions are often subjected to time-dependent loss of coating and loss of material due to corrosion; this causes reduction in the cross-sectional properties of the members, ... -
Global analysis of floating offshore wind turbines with shared mooring system
(Peer reviewed; Journal article, 2021)Floating wind turbines (FWTs) with shared mooring systems can be one of the most cost- effective solutions in reducing mooring costs. First, the static configuration of a shared line is estimated using the elastic catenary ... -
Investigation of updating methods for probability-informed inspection planning for offshore structures
(Peer reviewed; Journal article, 2019)The paper presents a novel process for probability-informed inspection planning based on the following principles. 1) A description of the strength of knowledge about a problem shall be included and be accounted for in the ... -
Resonant Motions of Dynamic Offshore Structures in Large Waves
(Peer reviewed; Journal article, 2021-10)In marine engineering, the dynamics of fixed offshore structures (for oil and gas production or for wind turbines) are normally found by modelling of the motion by a classical mass-spring damped system. On slender offshore ... -
Response sensitivity of a semisubmersible floating offshore wind turbine to different wind spectral models
(Peer reviewed; Journal article, 2020)Previous research on the OC3 spar floating offshore wind turbine (FOWT) has shown the sensitivity of the yaw and side-side modes' load and motion responses to different atmospheric conditions. Using the same baseline turbine ... -
Simulated wind-generated inertial oscillations compared to current measurements in the northern North Sea
(Journal article, 2018-06)Measured current speed data show that episodes of wind-generated inertial oscillations dominate the current conditions in parts of the northern North Sea. In order to acquire current data of sufficient duration for robust ... -
State of the art in structural health monitoring of offshore and marine structures
(Peer reviewed; Journal article, 2023)This paper deals with state of the art in structural health monitoring (SHM) methods in offshore and marine structures. Most SHM methods have been developed for onshore infrastructures. Few studies are available to implement ... -
Survival in cold waters - learnings from participation in cold water exercises - a regulatory perspective related to the Norwegian offshore industry
(Peer reviewed; Journal article, 2019)Participation in exercises lead by the University of Stavanger, the SARex 1 in 2016 and SARex 2 in 2017, provided valuable lessons related to survival in a cold maritime environment. The scenario of the exercises was a ... -
Systems dynamic model of wear evolution for sheaves used in oil and gas hoisting operations
(Peer reviewed; Journal article, 2023)The global offshore drilling contracted fleet consisted of 378 jack-ups, 68 semisubmersibles and 73 drillships, according to Westwood Global Energy Group, as of September 2023. In most regions of the world, rig activity ... -
Two-body dynamic simulations of a combined semi-submersible floating offshore wind turbine and torus wave energy converter
(Peer reviewed; Journal article, 2023)Dynamic responses of a combined wind and wave energy system which consist of a 5MW semi-submersible floating offshore wind turbine (FOWT) and a torus-shaped wave energy converter (WEC) are investigated. In the investigated ...
