Time to Rescue for Different Paths to Survival Following a Marine Incident
(Peer reviewed; Journal article, 2020-12)The time required for rescue is a critical factor for surviving a marine incident. The regulatory framework, International Maritime Organization (IMO) Polar Code, utilizes a risk-based approach. It states that the vessel ... -
Problem and models of multicriteria decision making and risk assessment of the arctic offshore oil and gas field development
(Peer reviewed; Journal article, 2019-11)The article is devoted to the systematic solution of problems of multi-criteria assessment and the possibility of implementing projects for the development of hydrocarbon deposits on the Arctic shelf under conditions of ... -
Investigation of the mechanical properties of Acacia tortilis fiber reinforced natural composite
(Peer reviewed; Journal article, 2020-10)The work presented in this paper is motivated by the fact that use of natural fiber materials for structural and non-structural applications have increased within the last two decades. In addition to the known benefits of ... -
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 ... -
Optimization of the Local Failure Design of Carbon-Fibre Epoxy Composite Curved Plates
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2021-01-15)This thesis presents the optimization of the local failure design of Carbon-Fiber Epoxy Composite used in the manufacturing of the curved plates. As relatively new and reliable material carbon fiber can be used in different ... -
Numerical study on gap resonance coupled to vessel motions relevant to side-by-side offloading
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-07-13)Floating Liquefied Natural Gas (FLNG) systems are large facilities dealing with offshore storage, processing, and transport of natural gas from the ocean basin. These enormous vessels allow the natural gas to be produced ... -
Timber-concrete composite beam, Cross laminated timber slab and Reinforced concrete beam/slab; A comparative of two case study for structural design, environmental impact and economy.
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-12)This thesis discusses two case studies, where case 1 is compared Timber-concrete composite (TCC) beam and Reinforced concrete beam (RC beam), while case 2 is compared Cross laminated timber (CLT) slab and Reinforced concrete ... -
Offshore Wind Turbine Loads and Motions in Unstable Atmospheric Conditions
(Peer reviewed; Journal article, 2019)Even though it is widely known that unstable atmospheric stability conditions can lead to higher turbulence, the use of proper turbulent wind models considering unstable conditions are not often used in the simulation of ... -
Design of steel bridge girders against ship forecastle collisions
(Peer reviewed; Journal article, 2019-10)A key aspect in the design of mega bridge structures across navigable waterways is to ensure bridge safety with respect to accidental ship collisions. Special attention has been paid to providing sufficient impact resistance ... -
Use of simulator training to mitigate risks in arctic shipping operations
(Peer reviewed; Journal article, 2019)Over the recent years, ship traffic in the polar areas has increased. There is reason to believe that this traffic, and especially the cruise traffic, will increase further as the ice retracts towards the poles. There is ... -
CFD simulations of a suspension bridge deck for different deck shapes with railings and vortex mitigating devices
(Peer reviewed; Journal article, 2019)Aerodynamic response of a single-box suspension bridge girder is investigated using CFD simulations. The importance of including railings and vortex mitigating devices such as guide vanes and a spoiler in the simulations ... -
Scalability and compatibility analyses of airborne wind technology for maritime transport
