Cargo Stowage Planning in RoRo Shipping: Optimisation Based Naval Architecture
(Master thesis, 2012)Operations research has proven itself to be advantageous in several areas of the industry for many years, but is operations research a good approach to operational maritime planning? Expressions used to calculate the initial ... -
Cavity flows and wake behind an elliptic cylinder translating above the wall
(Doctoral theses at NTNU, 2020:312, Doctoral thesis, 2020)Vortex formation is one of the fundamental modes in fluid mechanics and it can develop in almost every realization of fluid motion. Studying its fundamental dynamics and interactions is of great interest for engineering ... -
CFD in conceptual ship design
(Master thesis, 2011)Computational Fluid Dynamics (CFD) has been around for many years. It is a computer tool that can be used to find the hydrodynamic fluid performances. In ship design it is used in a wide area from smoke propagation to ... -
CFD investigation on scour beneath different configurations of piggyback pipelines under steady current flow
(Peer reviewed; Journal article, 2022)Scour beneath piggyback pipelines laid on a sandy seabed is numerically investigated by solving two-dimensional (2D) Unsteady Reynolds-averaged Navier-Stokes (URANS) equations. The fluid flow and the sediment transport are ... -
Challenges and proposals for managing major accident risk through the planning process
(Journal article; Peer reviewed, 2016)Major accidents are characterized by complex causal patterns with many factors influencing the occurrence of such accidents. The causes can be found not just in the execution of the work, but also in the preparations and ... -
Challenges and Solutions for Autonomous Systems Safety–Findings from three International Workshops (IWASS)
(Chapter, 2023)Autonomous systems intend to be a stepping-stone towards safer and more efficient operations. Extensive mapping and monitoring of land, space, and the oceans, renewable energy harvesting and production, inspection of ... -
Challenges with bringing collision risk models used in the north sea and norwegian sea to the Barents Sea
(Journal article; Peer reviewed, 2015)Norwegian offshore oil and gas exploration and production is moving into new and previously unexplored areas further north, such as the Barents Sea. This poses multiple new challenges in design, development and operation. ... -
Change in risk picture by going from a conventional sea cage to a submersible cage concept in Norwegian fish farming
(Master thesis, 2022)Norsk oppdrettsnæring står i dag overfor bærekrafts- og produksjonsutfordringer knyttet til lakselus og arealutnyttelse. I denne forbindelse har ScaleAQ redesignet ei konvensjonell oppdrettsmerd til å kunne senke not posen ... -
Changes in surge and pitch decay periods of floating wind turbines for varying wind speed
(Journal article; Peer reviewed, 2019)Recently published experimental results show variations in surge and pitch decay periods of floating wind turbines (FWTs) subjected to different incident wind velocities. This paper explores the external loads acting on a ... -
Changes in vessel traffic patterns following new platform installation
(Master thesis, 2017)Installation of a new offshore facility in an oil field is affected by the vessel routes that sail in the vicinity of the installation area. To avoid a collision with facility or reduce the collision frequency, navigating ... -
Chapter 9 Modeling and Analysis of Offshore Floating Wind Turbines
(Chapter, 2018)Offshore wind reserves vast amount of energy that could be effectively tapped to meet the demand for a greener global energy portfolio. To date, only a small fraction of offshore wind resources has been accessed worldwide, ... -
Characterisation of extreme load responses of a 10-MW floating semi-submersible type wind turbine
(Peer reviewed; Journal article, 2023)The global average size of offshore wind turbines has increased steadily from 1.5 MW to 6 MW from 2000 to 2020. With this backdrop, the research community has recently looked at huge 10–15 MW class floating offshore wind ... -
Characterisation of Near-Inertial Internal Waves in the Deep Hypolimnion of a Large Lake (Lake Geneva)
(Master thesis, 2022)Water quality in lakes is determined by concentrations in various dissolved substances. Deep lakes in mild climates, such as Lake Geneva, are thermally stratified water bodies, which means they present a vertical structure ... -
Characteristics of breaking irregular wave forces on a monopile
(Journal article; Peer reviewed, 2019)The substructures of offshore wind turbines are subjected to extreme breaking irregular wave forces. The present study is focused on investigating breaking irregular wave forces on a monopile using a computational fluid ... -
Choke condition and performance monitoring
(Master thesis, 2010)Sand production is a common complex problem in the oil and gas industry, and choke valves is typically suffering for this in form of erosive damage. The degree of erosive damage is decided by many different factors where ... -
Clarifying the concept of operational risk assessment in the oil and gas industry
(Journal article, 2018)There is an increasing interest in risk and safety research to reflect risk fluctuations in operational phase to avoid major accidents from happening. A structured review that covers operational risk assessment, dynamic ... -
Classification of risk to support decision-making in hazardous processes
(Journal article, 2015)Application of risk assessments developed for the design phase to support decision-making in operational settings has exposed weaknesses in how risk is analysed and expressed in an operational context. The purpose of this ... -
Clump-weight trawl gear interaction with submarine pipelines
(Master thesis, 2012)Clump weights come in several shapes, with a mass generally between 2 to 9 tons [5]. With extensive oshore development in the last decades, vast networks of pipelines are installed on the sea bottom. With both pipeline ... -
Clump-weight Trawl Gear Interaction with Submarine Pipelines
(Master thesis, 2011)A recent development in bottom trawling is the use of twin trawl equipment, where two trawl nets are towed side by side from a single vessel. This increases the catch rate and efficiently of the trawler. Governed by cost ... -
