Analysis and Simulation of the Rate of Heat Release (ROHR) in Diesel Engines
(Master thesis, 2013)As the restrictions for emissions from diesel engines are getting stricter, alternative fuels get more attention. Alternative fuels that can be used directly on already existing engines must be investigated to compare their ... -
Nonlinear Hydrodynamic Effects for Bottom-Fixed Wind Turbines
(Master thesis, 2013)This master thesis investigates possible effects from nonlinear wave loading onbottom fixed offshore wind turbines. The resonant phenomena springing andringing are reviewed with focus on their cause, and their possible ... -
Dynamic Analysis of a Subsea Module During Splash-zone Transit
(Master thesis, 2013)This thesis carries out a research on the dynamic performance of the template during the lowing operation through splash-zone. During the lifting operation, especially under harsh environment, the waves, winds as well as ... -
Upheaval Buckling of Offshore Pipelines
(Master thesis, 2013)The main purpose of this thesis was to develop a MATLAB program based on Terndrup-Pedersen? analytical method for upheaval buckling analysis and verify the analytical model by comparing with FE analysis using software ... -
Assessment of structural requirements related to LNG fuel tanks
(Master thesis, 2013)This thesis considers collision between ships, and the structural resistance of the struckship with the aim to minimize the indentation into the ship side.First it gives a background in ship collision analysis, different ... -
Experimental, numerical and analytical investigation of the effect of screens on sloshing
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:118, Doctoral thesis, 2013) -
Trajectory Tracking Motion Control System for Observation Class ROVs
(Journal article, 2013)This paper proposes a MCS (Motion Control System) with trajectory tracking capability for observation class ROVs (Remotely Operated Vehicle) used to carry out automated high-resolution image capturing missions, e.g. ... -
Simulation of Viscous Flow Around a Circular Cylinder with OpenFOAM
(Master thesis, 2013)Flow around a circular cylinder has been extensively studied, both numerically and experimentally, for a number of years. With the increase in flow-structure interactions around marine structures such as platform legs/columns, ... -
Design of an Offshore Standby Base for Remote Regions
(Master thesis, 2013)In this Master?s thesis an optimization model for finding the optimal design of a standby base operating in remote regions is presented. The research and development within optimization of standby vessel design is limited. ... -
Iceberg shape characterization for damage assessment of accidental impacts with ships and offshore structures
(Master thesis, 2013)The northern areas are becoming more and more attractive because off the large oil and gas reservoir that is there. In this area there is a harsh environment and the possibility to collide with an iceberg increases as the ... -
A New Small-Scale LNG Distribution and Bunkering Facility: - An Approach to Risk Based Design and Verification
(Master thesis, 2013)LNG is the preferred solution to meet environmental requirement and a great market growth is expected within few years. Lack of suitable infrastructure, regulation and bunkering practices poses challenges to the industry, ... -
Theoretical and experimental investigation of a free running fishing vessel at small frequency of encounter
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:327, Doctoral thesis, 2013)The hydrodynamic behaviour of a fishing vessel in a seaway was studied. The focus was on small frequencies of encounter, corresponding to following and stern quartering seas, where fishing vessels are susceptible to capsize. ... -
Potential-Flow Predictions of a Semi-Displacement Vessel Including Applications to Calm-Water Broaching
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:155, Doctoral thesis, 2013)As a marine vehicle’s operational speed increases, hydrodynamic pressure plays an increasingly significant role in carrying the vessel’s weight. The shift of importance from hydrostatic to hydrodynamic pressure may cause ... -
Study of Critical Imaging Parameters and Variables for Environmental Monitoring Using an ROV with Experimental Results
(Master thesis, 2013)In the oil and gas industry there is a high focus on integrating technology in the environmental monitoring happening before, during and after an offshore operation. In order to properly monitor the underwater environment, ... -
Planning and disruption challenges in the logistical offshore supply chain based on a simulation model
(Master thesis, 2013)The offshore industry is a dynamic industry with constant demand changes. This creates many challenges, one of them being logistical supply planning. The need changes fast and this makes it important to receive the deliveries ... -
Fleet-Oriented Spare Parts Management - Philosophy, work processes and scientific methods for spare parts management
(Master thesis, 2013)There are 22 construction support vessels in the DOF Group that have active heave compensated cranes with lifting capacity of above 50 tonnes. The Brazilian flagged Skandi Salvador was chosen to represent the fleet in terms ... -
Oscillating foil propulsion
(Master thesis, 2013)Unsteady foil theory is discussed and applied on several cases of an oscillating foil. The oscillating foil is meant as a propulsion system for a platform supply vessel.Four case studies of foil oscillation have been ... -
Hull Dimensions of a Semi-Submersible Rig: A Parametric Optimization Approach
(Master thesis, 2013)Semi-submersible rigs are utilized to perform drilling, production and intervention operations in the oil and gas industry. The design of the rigs is a complex task which today is highly dependent on manual iteration and ... -
Evaluation of Environmental Effects of Propulsionsystems for a PSV
