dc.description.abstractThe topic of this thesis is time domain analysis of mooring line effects on a vessels response, where a barge is used as test model. This type of simulation can be used to investigate and evaluate how the forces from the mooring line affects the vessels response over time. As an introduction, some background theory regarding anchor handling and vessel stability is presented. The objective of the thesis is to show how the mooring line is affecting the vessel response, mainly heave, pitch and roll.nb_NO
dc.description.abstractBoth the barge and mooring line is modelled and simulated by using Aquasim, a software package delivered by Aquastructures. The package includes the programs AquaEdit, AquaBase, AquaView and AquaTool which are all used as aid in this project. This software is specialized on mooring analysis related to the aquaculture industry and some offshore operations. For purely analysing vessel response it is unproven and verifying its suitability is a part of the project.nb_NO
dc.description.abstractThe barge model is matched against ShipX, which is a proven software when it comes to vessel response simulation, to verify that the model is acting realistically. Due to limitations to the program the model used for this project has some limitations which are reflected upon at the end of the report.nb_NO
dc.description.abstractDifferent case studies are simulated. The results indicate that there is a connection between the variations in mooring line force and the vessel response. Worsened environment, mainly increased wave height and current causes more variations and unpredictability.nb_NO
