Numerical Predictions of Global and Local Ice Loads on Ships
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:154, Doctoral thesis, 2011)Ice loads represent the dominant load for ice-going ships, and it is important to estimate both global and local ice loads on ship hulls. The global ice load governs the ship’s overall performance in ice, and it is an ... -
Machinery vibrations in the Skjold class of MTB's
(Master thesis, 2011)During test and verification of the Norwegian Navy’s fast patrol boat KNM Storm some problems with the lift fan machinery have been experienced. The problem observed is that occasionally, triggered by the firing of the 76 ... -
Application of an Oil Spill Response Model in Ice-bridge Simulator Training
(Master thesis, 2011)The oil spill emergency response and recovery in the Arctic Ocean has been since a major area of research. The use of previously practiced methods such as oil spill response options – with the implementation of mechanical ... -
Parametric Roll Resonance of a Fishing Vessel as function of Forward Speed and Sea State
(Master thesis, 2011)The subject of this thesis is sea keeping and stability of a fishing vessel in regular waves, with focus on parametric roll resonance. Parametric roll resonance is resonance in roll due to time variation of a parameter, ... -
Zero Failure Management at Maximum Productivity in Safety Critical Control Room
(Lecture, 2011)Predicted growth in air traffic and demand for increased safety, predictability, and efficiency impose additional demands on Air Traffic Management (ATM) systems. Different technologies are currently under development to ... -
Viscous flow around a circular cylinder near a plane wall
(Master thesis, 2011)Marine pipelines placed at or near the seabed are exposed to currents and waves. In the presence of a sedimentary seabed, the interaction between the surrounding water motions and the pipeline may cause erosion of sediments ... -
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 ... -
Stochastic Dynamic Response Analysis of Spar-Type Wind Turbines with Catenary or Taut Mooring Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:8, Doctoral thesis, 2011)Floating wind turbines can be the most practical and economical way to extract the vast offshore wind energy resources at deep and intermediate water depths. The Norwegian Ministry of Petroleum and Energy is strongly ... -
Dynamic Response Analysis of a Spar Type Floating Wind Turbine
(Master thesis, 2011)Wind power is a large natural source for renewable energy, and many countries have shown interest in establishing floating offshore wind parks. There are many advantages with floating offshore wind turbines, but also many ... -
Azimuth Propulsors in Off-design Conditions
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:186, Doctoral thesis, 2011)While the use of azimuth propulsors such as azimuth thrusters and podded propulsors as main propulsion device on ships has been growing quite fast, the understanding of hydrodynamics related to propulsors in real operational ... -
Energy efficient operation of ships
(Master thesis, 2011)By reducing ships’ fuel consumption, shipowners can achieve lower operating costs while at the same time reducing their impact on the environment. This report is a study of different measures that can be taken in order ... -
Structural strength of work boats and high speed crafts with pre-fabricated, floating panels in aluminum
(Master thesis, 2011)This thesis evaluates some relevant aspects related to structural integrity for work boats and high speed vessels with floating frames. This structural design is expected to significantly reduce the building cost, but it ... -
Numerical and Experimental Investigation of Added Resistance in Waves
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:329, Doctoral thesis, 2011)Added resistance in waves is important for ship powering performance, since ships are travelling most of the time in waves, not in calm water. With increasing focus on fuel consumption and greenhouse gas emissions, there ... -
Guidance & Control Strategies for UUVs
(Master thesis, 2011)Focus on safety and effectiveness in the oil and gas industry has increased the need for advanced control system for underwater vehicles. For remotely operated vehicles (ROVs) effectiveness when conducting deep sea operation ... -
Fatigue of Pipelines resting on Uneven Seabed
(Master thesis, 2011)Subsea pipelines represent the most cost effective way of transporting oil and gas from the subsea field to the market. A large network of subsea pipelines has therefore been installed both at the Norwegian continental ... -
Analysis of Accidental Iceberg Impacts with Membrane LNG Carriers
(Master thesis, 2011)The topic of this report is accidental iceberg collision with the bow shoulder area of a 150000ton membrane-type LNG carrier. It is expected that the traffic of LNG-carriers will increase in the arctic areas in the years ... -
Analysis and monitoring of drilling risers on DP vessels
(Master thesis, 2011)The object of this master thesis is to investigate a drilling riser exposed to currents, waves and vessel motions at different water depths. The aim is to develop an advisory system for vessel position based on the riser ... -
Requirements and concepts for arctic evacuation
(Master thesis, 2011)Operation of manned oil and gas installations in arctic locations is complicated and presents new challenges. One of the challenges is to maintain the safety of the crew, by obtaining adequate lifeboat systems for crew ... -
Assessment of oil spill in ship collision and grounding
