Dynamic Simulation and Control of an Active Roll Reduction System Using Free-Flooding Tanks With Vacuum Pumps
(Chapter; Peer reviewed, 2017)Ship roll motion is often the critical factor for offshore operations due to its lack of damping mechanism. This paper demonstrates a dynamic simulation scheme of an active roll reduction system using free-flooding tanks ... -
Dynamic Simulation of a Hydraulic Cylinder for Heave Compensation of Deepwater Drilling Risers
(Doctoral thesis at NTNU;2014:320, Doctoral thesis, 2014)This thesis presents global finite element simulations of a hydro-pneumatic riser tension cylinder used for tensioning and heave compensating of marine drilling risers. The global finite element models are made for use ... -
Dynamic Simulation of a Mooring Catenary Based on the Lumped-Mass Approach: OpenModelica and Python Implementations
(Chapter, 2020)In this paper, the theoretical background behind the formulation and solution of a discretized lumped-mass mathematical-model of the physically continuous and inelastic mooring catenary is re-visited. The drag term of the ... -

Dynamic simulation of deep water drilling risers with heave compensating system
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:175, Doctoral thesis, 2012)This thesis discusses modelling aspects related to dynamic analysis of deep water drilling risers. These risers must have a heave compensator that maintains a near constant tension independent of platform motions. Traditional ... -
Dynamic simulation of future integrated energy systems
(Doctoral theses at NTNU;2019:213, Doctoral thesis, 2019)The building sector is responsible for a large part of the world's total energy use. More than half of building energy use is needed for space heating, domestic hot water heating, and space cooling. Thermal energy supply ... -
Dynamic Simulation of Gas Expansion in Marine Risers
(Master thesis, 2016)The main objective of the work is to study the dynamic behavior of gas expansion in marine risers. In case of well control situations in deep and ultra deep waters, gas influx shows no warnings if not little, making it ... -
Dynamic Simulation of Module Installation on Deep Water
(Master thesis, 2015)The Aasta Hansteen field is a gas field outside the coast of Northern Norway. Production is planned to start in 2017. The gas field is situated at 1300m water depth the deepest on the Norwegian continental shelf. During ... -
Dynamic Ssimulation Of Dart Anchor Installation
(Master thesis, 2015)Over the few last decades, numerous mooring concepts have been developed, one of these being the dart/ torpedo anchor. A torpedo anchor is shaped like an arrow and is equipped with tail fins to provide good directional and ... -
Dynamic Storage Location Assignment Using Operator Idle Time for Reshuffling of Goods in a Manually Operated Warehouse
(Master thesis, 2022)Ettersom markedet for tredjepartslogistikk (3PL) har vokst de siste tiårene har konkurransen i bransjen også økt. Derfor må 3PL-leverandører være smartere i driften for å redusere kostnadene og forbli konkurransedyktige. ... -
