Bow design for low added resistance in waves
Kuntz, Raphaël (Master thesis, 2023)Med tanke på å redusere utslipp fra sjøtrafikken er jakten på et skips effektivitet avgjørende. I sjøen er bølger ansvarlig for ekstra motstand og øker energien som trengs for å bevege skipet fremover. Ekstra motstand er ... -
Bølgemodellering i kystområder
Malisz, Michal Edward; Scholze, Mathias (Bachelor thesis, 2019)SWAN er et bølgemodelleringsprogram som brukes til å simulere bølgeforplantning i kystområder. Formålet med dette dokumentet er å fastslå nøyaktigheten av resultatene fra SWAN. Derfor er Sulafjorden et bra emne, siden det ... -
Description of ship motion and comparison of a real-time unified hydrodynamic model with free running tests in calm water and regular waves
Zghyer, Rami; Halse, Karl Henning (Chapter, 2020)Ship bridge simulators are well established in education practices of seafarers and mariners. The use of simulators in research is ramping up due to the EU motivation towards Blue Growth, where the quantity and quality of ... -
Dual Quaternion Variational Integrator for Rigid Body Dynamic Simulation
Xu, Jiafeng; Halse, Karl Henning (Research report, 2016)In rigid body dynamic simulations, often the algorithm is required to deal with general situations where both reference point and inertia matrix are arbitrarily de- fined. We introduce a novel Lie group variational integrator ... -
DYNAMIC RESPONSE ANALYSES OF A SEMI-SUB INSTALLATION VESSEL DURING THE INSTALLATION OF A WIND TURBINE ONTO A FLOATING SPAR BUOY
Remmen, Hans Marius (Master thesis, 2019)Studien starter med en kort introduksjon til temaet marine operasjoner, med fokus på SSP teknologi og løfteoperasjoner. Det er mye informasjon om bruken av nedsenkbare plattformer i olje- og gassindustrien, men ikke så mye ... -
Dynamic response analysis of a catamaran installation vessel during the positioning of a wind turbine assembly onto a spar foundation
Jiang, Zhiyu; Li, Lin; Gao, Zhen; Halse, Karl Henning; Sandvik, Peter Christian (Journal article; Peer reviewed, 2018)Installation of floating wind turbines is a challenging task. The time and costs are closely related to the installation method chosen. This paper investigates the performance of an efficient installation concept – a ... -
Dynamic Response Analysis of Catamaran Installation Vessel During the Mating Process of a Wind Turbine onto a Floating Spar Buoy
Kalathingal Thody, Ramees (Master thesis, 2019)Present day energy production and consumption techniques are deeply rooted in methods which are unsustainable and therefore cannot be relied upon. Hence, there is an urgent call for an alternative clean and renewable energy ... -
