Relative Motion Calculator
(Master thesis, 2012)AbstractThe wind power business has in recent times changed its focus from land-based installations to offshore installations. This has presented challenges both technological and financial, mainly related to construction ... -
Sea State Limitations for the Deployment of Subsea Compression Station Modules
(Master thesis, 2012)Deployment of a large box structure in many sea states has been investigated. Two deployment methods are compared; crane installation over the side and through moonpool installation. The structure is 12 [m] long, 6 [m] ... -
Speed and powering prediction for ships based on model testing
(Master thesis, 2012)The ITTC78 method was originally designed for conventional single screw ships, but has later been modified to adapt twin screw ships and podded propulsors. Nowadays even more unconvensional propulsors are introduced, and ... -
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 ... -
Verifying and Validation of a Manoeuvring Model for NTNU's Research Vessel R/V Gunnerus
(Master thesis, 2012)MARINTEK's ship motion simulation program SIMAN (ShipX manoeuvring module) is used to develop a ship motion model for NTNU's research vessel R/V Gunnerus. SIMAN uses a 3-DOF linear mathematical model to describe the vessel's ... -
Viscous Flow Around Finite Lenght Circular Cylinder
(Master thesis, 2012)Viscous flow around circular cylinders is a classical research topic in fluid dynamics with a vast amount of practical applications in the field of offshore marine technology. In the flow around cylinders of finite length, ... -
Vortex Induced Vibrations of Marine Risers
(Master thesis, 2012)SummaryThis Master s Thesis goal is to present fundamental physical aspects of Vortex Induced Vibrations (VIV) of marine risers, and outline methods for suppression of VIV. Main emphasis has been given to the use of strakes, ... -
Wave Conditions for Offshore Wind Turbine Foundations in Intermediate Water Depths
(Master thesis, 2012)In this thesis, the effects on regular waves when propagating from deep to shallow water have been investigated, assuming linear wave theory. The effects of shoaling, refraction, reflection and diffraction have been studied. ...
