Simultaneous stochastic model of waves and currents for prediction of structural design loads
(Doctoral theses at NTNU;2017:355, Doctoral thesis, 2017)Simultaneous data of metocean parameters, such as wind, waves and current, of sufficient quality and duration are necessary to establish reliable, joint models of metocean loads and load effects on marine structures. In ... -
Single blade installation using active control of three tugger lines
(Chapter, 2018)Single blade installation using jack-up vessels is a commonly used blade installation setup for offshore wind turbines. During this operation, each blade is lifted by the main crane from the deck, moved, and then bolted ... -
Single blade installation with a floating monohull crane vessel - Establishing the operational limits while using dynamic controlled taglines
(Master thesis, 2021)Abstract will be available on 2024-11-01 -
Single Vehicle Flexible and Selective Delivery Routing Problem in Offshore Bulk Shipping - Cutting Costs and Improving Planning by Use of Optimization
(Master thesis, 2017)A decision support model for the Single Vehicle Flexible and Selective Delivery Routing Problem (SVFSDRP) is presented as a method to improve planning and reduce costs in offshore bulk logistics. Reducing costs in the ... -
Site surveys at Norwegian aquaculture sites - Methodologies for wave estimation
(Master thesis, 2018)New concepts of ocean-based fish farming are emerging in the aquaculture industry, which aim to increase production efficiency and expand usable farming space. These recent developments raise a need for evaluating present ... -
Site-specific controller design for monopile offshore wind turbines
(Journal article; Peer reviewed, 2018)The fatigue life of offshore wind turbine (OWT) support structures is sensitive to variations in site-specific conditions such as the water depth and soil properties. Site condtions may vary significantly within a wind ... -
Sizing Optimization of a Hybrid Shipboard Power System for Low-Emission Shipping
(Master thesis, 2019)Valget av maskinerisystemet for et skip er i utgangspunktet en kompleks oppgave. Skip er konstruert med tanke på en levetid på 20-25 år, og vil derfor være utsatt for både endringer i operasjonelle krav, så vel som ... -
Sloshing in a rotating liquid inside a closed sea cage for fish farming
(Peer reviewed; Journal article, 2021)Sloshing in a sea cage with a slowly rotating liquid is investigated. The cage is axisymmetric, and the liquid is subjected to a nearly uniform angular velocity about the vertical axis of the cage. Both experimental and ... -
Sloshing in rectangular tanks and interaction with ship motions
(Doktoravhandlinger ved NTNU, 1503-8181; 16, Doctoral thesis, 2002)Sloshing is a violent resonent free surface flow in a container. The main objective of this thesis has been to study sloshing in rectangular and prismatic tanks. The tank may be excited by a harmonic motion or it may move ... -
Sloshing in Upright Circular Containers: Theory, Analytical Solutions and Applications
(Book, 2020)This book presents mathematical fundaments and results on sloshing in an upright circular cylindrical tank with semi-analytical solutions. The book outlines generic mathematical and physical aspects of the multimodal method, ... -
Sloshing induced tank-roof impact with entrapped air pocket

Sloshing-induced motions of a spar inside a cylindrical dock with baffles in waves
(Peer reviewed; Journal article, 2023)The motions of a free floating offshore wind turbine’s (OWT) spar-type platform inside a bottom-less moored cylindrical dock are investigated for incident wave frequencies near the first lateral sloshing resonance, focusing ... -
Slug flow and waves induced motions in flexible riser
(Journal article; Peer reviewed, 2018)Flexible risers provide optimum solutions for deep water offshore fields. Reliable dynamic analysis of this kind of slender structure is crucial to ensure safety against long time fatigue failure. Beyond the effects from ... -
Small scale experimental validation of a numerical model of the HarshLab2.0 floating platform coupled with a non-linear lumped mass catenary mooring system
(Peer reviewed; Journal article, 2020)When focusing on mooring system numerical modelling, the efforts are focused on validating models that increase the accuracy and maintain the computation time under reasonable limits. In this paper an approach for modelling ... -
Small Water Plane Area Solutions for Access of Offshore Wind Turbines
(Master thesis, 2015)In 2014, 536 offshore wind turbines were installed on European shelf, connecting an average of 5.9 MW to the grid every day. About two thirds of this were installed in the North Sea. This new and emerging market represents ... -
Small-Scale Automation in Shipbuilding - An Investment Study for Automated Hull Production in High-cost Countries
(Master thesis, 2015)The globalized market enforces a great cost pressure on all the shipbuilding actors. Norwegian yards, representing countries with high local wages and prices, is under pressure to make changes if they want to keep up with ... -
Snaking Behavior of Umbilicals
(Master thesis, 2014)Umbilical is a hardware element that connects the subsea systems to the top side systems of a floating production unit. During its manufacture, storage and installation, sometimes it shows behaviour like snake as found in ... -
Soft Causes with Hard Consequences: The role of organisational factors in the creation of structural integrity
(Journal article; Peer reviewed, 2015)Structural integrity is usually seen as a result of design, calculations, the correct choice of materials and good engineering practice in general. In this paper, we will shed light on organisational aspects that can ... -
