An upright bottomless vertical cylinder with baffles floating in waves
(Peer reviewed; Journal article, 2022)Damping of the surge and pitch motions, as well as the first lateral sloshing mode in a rigid free-floating upright circular dock with bilge boxes and open bottom is investigated. Model tests are carried out on a 0.80 m ... -
Upscaling, analysis, and design of a floating vertical axis wind turbine - Oppskalering, analyse, og design av en flytende vindturbin med vertikal aksle
(Master thesis, 2018)There are currently two main trends governing research and development in the offshore wind industry. The first one is upscaling, i.e. manufacturing larger and more powerful wind turbines; the second one is platform ... -
Use of an Autonomous Surface Vehicle reveals small-scale diel vertical migrations of zooplankton and susceptibility to light pollution under low solar irradiance
(Journal article; Peer reviewed, 2018)Light is a major cue for nearly all life on Earth. However, most of our knowledge concerning the importance of light is based on organisms’ response to light during daytime, including the dusk and dawn phase. When it is ... -
Use of CFD to Study Hydrodynamic Loads on Free-Fall Lifeboats in the Impact Phase.: A verification and validation study.
(Master thesis, 2012)In the past, testing of lifeboat design has been carried out solely by experimental means. However, due to the large number of factors which influence the loads on the lifeboat structure and its occupants, optimization ... -
Use of Clusters in a Route Generation Heuristic for Distribution of Fish Feed
(Master thesis, 2017)Fish farming is an industry in growth which is also expanding its area of operation. Among the biggest cost-contributors are costs associated with the distribution of fish feed. The demand is heavily varied and the system ... -
Use of in-service data to determine the added power of a ship due to fouling
(Master thesis, 2019)Det er et økende fokus på energi effektivitet i verden og shipping industrien er ikke noe unntak. Nye og strengere regler om utslipp er ett eksempel på dette. Flere og flere skip blir utstyrt med automatiske data samlings ... -
Use of oil tanker return/ballast space for the transportation of freshwater
(Master thesis, 2010)This report analyzes the concept of using oil tankers’ free cargo space and/or segregated ballast tanks to transport freshwater on the return leg, i.e. from oil unloading port back to oil loading port – also called freshwater ... -
Use of OpenFOAM in the Rolls-Royce Propulsion Open Water Simulation system
(Master thesis, 2017)Rolls-Royce Research \& Technology propulsion department has developed a fully automated open water simulation tool called Propulsion Open Water Simulations. This system can be used for any propulsion and thruster system. ... -
Use of response forecasting in decision making for weather sensitive offshore construction work
(Peer reviewed; Journal article, 2023)Response forecasting is an emerging technology for supporting decision-making during offshore construction work. The method aims to improve the reliability and efficiency of weather-sensitive operations. This article ... -
Use of SIMA in a static and dynamic analysis of a spool piece installation
(Master thesis, 2011)A new modeling environment for marine operations, SIMA, has been used to perform a spool piece installation analysis. Spool design and installation analyses have formerly been done in two separate operations. STAAD Pro has ... -
Use of Tunnel Thrusters and Azimuthing Thrusters for Roll Damping of Ships
(Master thesis, 2016)This thesis presents a novel technique of active roll damping in marine vessels by the sole use of conventional thrusters. Many marine operations, such as crane operation and helicopter landings, should be carried out in ... -
Use of Turbulence Stimulation on Ship Models
(Master thesis, 2018)In ship model testing the length based Reynolds number will be in the order of 100 times smaller than in full scale. As a consequence ship models often operates in the transition zone between laminar and turbulent flow. ... -
Using Autonomous Underwater Vehicles as Sensor Platforms for Ice-Monitoring
(Journal article; Peer reviewed, 2014)Due to the receding sea-ice extent in the Arctic, and the potentially large undiscovered petroleum resources present north of the Arctic circle, offshore activities in ice-infested waters are increasing. Due to the presence ... -
Using Deep Learning for Automatic Classification of Marine Habitats in HiSAS Imagery.
(Master thesis, 2018)This thesis aims to utilize an established image classification method to create a methodology for classifying cold-water corals in synthetic aperture sonar imagery. This will be performed by combining high-resolution sonar ... -
Using Epoch Era Analysis in the Design of the Next Generation Offshore Subsea Construction Vessels
(Master thesis, 2014)This thesis examines the plausibility of using Epoch-Era Analysis during conceptual design of the next generation offshore subsea construction vessel (OSCV). Spurred by high oil prices and a decreasing level of accessible ... -
Using Field Data and Parametric Studies to Create a Dynamic Model of a Seismic Spread
(Master thesis, 2018)In a seismic survey, many demanding operations are done using expensive equipment that can be challenging to handle. A dynamic model may be useful to predict the response of a seismic spread for different scenarios with ... -
Using Monte Carlo simulations to evaluate adaptive sampling strategies in synthetic and real ocean models
(Master thesis, 2021)Arven etter Nansen er et prosjekt som jobber for å forbedre tradisjonelle målinger gjort fra skip. En av måtene dette blir gjort på, er ved bruk av autonome undervannsfarkoster til adaptiv prøvetaking. Ved bruk av adaptiv ... -
Using Neural Networks to Predict the Response of a Floating Structure
(Master thesis, 2018)Floating structures are influenced by the ocean environment which cause responses from the structures known as surge, sway, heave, roll, pitch and yaw. These responses are commonly approximated using linear potential theory, ... -
Utslipp til luft og NOx - reduksjon på grunn av NEA på Marine dieselmotorer
