Indirect Measurements of Added-Wave Resistance on an In-Service Container Ship
(Chapter, 2021)This paper investigates a semi-empirical model used to estimate added-wave resistance on a ship sailing in waves. The model relies on measurements from a continuous monitoring system, and produces an estimate - the indirect ... -
Industrial lobster farming: a technical investigation and comparison of three different farming concepts
(Master thesis, 2023)Europeisk hummer (Homarus gammarus) er særdeles ettertraktet som sjømat, og det finnes en betydelig forbrukeretterspørsel etter arten. Den ville bestanden er kritisk lav flere steder, og etterspørselen er adskillig høyere ... -
Industry Best Practice Risk based design for LPG Facility: Gap in Bangladesh practice
(Journal article; Peer reviewed, 2017)Bangladesh safety regulations and practice is at nascent stage. Safety distance regulation for LPG installation does not match with prescriptive standard API 2510 or other international standards. No detail technical basis ... -
Influence of a Wavefoil on the Wave Pattern Resistance of a Ship
(Master thesis, 2018)The Reynolds-averaged Navier-Stokes equation has been numerically solved in order to study the interaction between the steady wave patterns of a wavefoil and ship hull, using the open source software OpenFOAM. Turbulence ... -
Influence of brittle fracture on the crashworthiness of ship and offshore structures in Arctic conditions
(Chapter, 2016)Structures operated in Arctic regions are exposed to low temperatures, which may be in the range of the ductile- brittle transition temperature (DBTT) of steel. This implies that the brittleness of the material in such ... -
Influence of deformation prior to ageing on fatigue behavior of extruded AA6082-T6 profiles
(Peer reviewed; Journal article, 2022)This paper investigates the effect of plastic deformation before artificial ageing on fatigue behavior of extruded AA6082-T6 profiles. As-received, T4-temper materials are pre-deformed at different strains and followed by ... -
Influence of internal rotational flow on wave response of a flexible closed containment system
(Master thesis, 2022)Denne oppgaven studerte påvirkningen av en intern rotasjonsstrøm på bølgeresponsen til en lukket fleksibel merd. Eksperimentelle tester ble utført på en modell i en skala 1:30. Modellen besto av en elastisk flyter, ... -
Influence of Mean Tension on Mooring Line Fatigue Life
(Chapter, 2020)Studies published in recent years have documented a significant mean load effect on fatigue capacity for offshore mooring chain, and show that a reduction of the mean load gives an increase in fatigue life. However, current ... -
Influence of motion coupling and nonlinear effects on parametric roll for a floating production storage and offloading platform
(Journal article; Peer reviewed, 2015)Occurrence and features of parametric roll (PR) on a weather-vaning floating production storage and offloading (FPSO) platform with a turret single-point mooring-line system are examined. The main focus is on the relevance ... -
Influence of operability criteria limiting values on ship speed
(Journal article; Peer reviewed, 2016)When the ship is caught in heavy seas, there are two manoeuvres that the shipmaster can undertake to avoid excessive ship motion and hull damage: changing course or voluntary speed reduction. This paper presents a study ... -
Influence of ship design complexity on ship design competitiveness
(Peer reviewed; Journal article, 2021)Complexity is discussed in design literature mainly through its negative and in some cases positive consequences. This article critically reviews and elaborates the effects of complexity on competitiveness in ship design, ... -
Influence of spanwise no-slip boundary conditions on the flow around a cylinder
(Journal article; Peer reviewed, 2017)First we present high resolution large eddy simulations (LES) for the flow past a circular cylinder at Reynolds number 3900 to prove the quality of the simulations. A thorough grid convergence study is presented, and the ... -
The Influence of the Rake Angle on the Cutting of Low-Lead and Lead-Free Brass Alloys
(Chapter, 2023)Components manufactured from brass alloys are widely used in plumbing systems. Traditionally, lead is added to the alloy to improve the machinability. In recent years, the use of lead has been restricted due to health and ... -
Influence of Turbocharger Inertia and Air Throttle on Marine Gas Engine Response
(Journal article, 2021)Due to the current emission legislation, improving the marine propulsion system performance has received considerable notice. Employing natural gas as the primary energy source presented remarkable attention in the lean-burn ... -
Influence of variability and uncertainty of wind and waves on fatigue damage of a floating wind turbine drivetrain
(Peer reviewed; Journal article, 2021)This study investigates the effect of variability and uncertainty of wind and wave conditions on the short-term fatigue damage of a 10-MW floating wind turbine drivetrain. Global dynamic responses of a semi-submersible ... -
Influence of yaw-roll coupling on the behavior of a FPSO: An experimental and numerical investigation
(Journal article; Peer reviewed, 2015)An inconvenience in the experimental set-up of a FPSO in regular waves highlighted occurrence of parametric-roll events promoted by yaw-roll coupling and motivated a combined physical and numerical analysis on the relevance ... -
Influences of upstream extensions on flow around a curved cylinder
(Journal article; Peer reviewed, 2018)In simulations of flow around a concave curved cylinder, i.e. free-stream aligned with the plane of curvature and directed towards the inner face of the curvature, one cannot avoid interactions between the cylinder and the ... -
Information and Decision-making for Major Accident Prevention – A concept of information-based strategies for accident prevention
(Doctoral theses at NTNU;2022:379, Doctoral thesis, 2022)With wide application of sensors and digitalization for accident prevention and safety management of sociotechnical systems, distributed decision-makers rely on information supplied for their decision-making more than ever. ...
