In-Line Vibrations of Flexible Pipes
(Chapter; Peer reviewed, 2017)A semi-empirical prediction tool for pure in-line vortex-induced vibrations is under development. The long-term goal is to be able to realistically model the dynamic behavior of free spanning pipelines exposed to arbitrary ... -
Including the Effect of Shielding in Prediction of Weather Window for Offshore Lifting Operations
(Master thesis, 2015)The offshore industry is constantly seeking to operate in more extreme conditions. DeepOcean is a subsea service company, where offshore lifts is a part of every day operations. To remain competitive, it is important to ... -
Incorporating software failure in risk analysis – Part 1: Software functional failure mode classification
(Peer reviewed; Journal article, 2020)Advanced technological systems consist of a combination of hardware and software, and they are often operated or supervised by a human operator. Failures in software-intensive systems may be difficult to identify, analyze, ... -
Incorporating software failure in risk analysis––Part 2: Risk modeling process and case study
(Journal article; Peer reviewed, 2020)The advent of autonomous cars, drones, and ships, the complexity of these systems is increasing, challenging risk analysis and risk mitigation, since the incorporation of software failures intro traditional risk analysis ... -
Increasing catch efficiency for Nephrops in deep-water shrimp (Pandalus borealis) trawl fisheries
(Peer reviewed; Journal article, 2022)In Skagerrak and the North Sea, coastal vessels harvest deep-water shrimp (Pandalus borealis) in a mixed fishery, in which catches of Nephrops (Nephrops norvegicus) are of economic importance for the fleet. Fishermen ... -
Increasing the Operation Window of Dynamic Positioned Vessels Using the Concept of Hybrid Control
(Chapter; Peer reviewed, 2014)In order to extend the operational window of marine vessels, the high-level control of the dynamic positioning (DP) system is revised. Major contributions of this paper include the modeling of a hybrid controller for a DP ... -
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
