Fault tolerant position mooring control based on structural reliability
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:156, Doctoral thesis, 2012)Safety of position mooring system is a prime concern in the marine industry and regulations are in force to prevent faults in equipment from causing failure of the whole system. There are many reasons for failures in ... -
Fault-tolerant Observer Design
(Master thesis, 2017)This master thesis dealt with the development of a fault-tolerant model-based observer for a low-cost ROV developed by BluEye Robotitcs, P2-Alpha. The observer was developed for 4 degrees of freedom (DOFs) using the installed ... -
Fault-tolerant Position-Mooring Control for Offshore Vessels
(Journal article; Peer reviewed, 2018)Fault-tolerance is crucial to maintain safety in offshore operations. The objective of this paper is to show how systematic analysis and design of fault-tolerance is conducted for a complex automation system, exemplified ... -
Feasibility of a green corridor serviced by a battery-powered cargo ship
(Master thesis, 2024)Internasjonal skipsfart er hovedbidragsyteren til transporterte varer, og står for transport av mer enn 80\% av de transporterte varene. Den internasjonale sjøfartsorganisasjonen (IMO) har satt en strategi for klimagassutslipp ... -
Feasibility of Deep-Sea Mining Operation Within Norwegian Jurisdiction
(Master thesis, 2016)Numerous hydrothermal vent sites are discovered along the Arctic Mid-Ocean Ridge (AMOR), stretching some 1,050 km from Jan Mayen to Svalbard, mostly within Norway s economically exclusive zone (EEZ). Associated with these ... -
Feasibility of mooring system optimization for floating wind turbines in deep water based on static analysis
(Master thesis, 2021)The goal of this thesis is to investigate the feasibility of optimizing the mooring line characteristics of a semi-taut (chain – polyester – chain) mooring system in combination with drag embedded anchors for a 12 MW wind ... -
Feasibility study of a floating system for extraction of wave energy
(Master thesis, 2011)The idea of harnessing energy from the ocean waves is a seductive one, a limitless resource. But the road from idea to success is long and has been traveled by many, the great achievements are few and far between. This ... -
Feasibility study of a system for damping ship pitch motions and extraction of wave energy
(Master thesis, 2011)A system for pitch motion reduction of offshore vessels is investigated for feasibility. An air chamber is simulated in the bow section of a case ship open to water in the bottom and with a small opening in the top where ... -
A Feasibility Study of Assessing Bunkering Operations Through AIS Data
(Master thesis, 2018)This thesis is a result of utilising Automatic Identification System data to construct a framework for identifying bunkering operations and conducting a statistical analysis of identified operations. The two objectives of ... -
Feasibility Study of the Complete Removal of Monopiles Using Vibratory Pile Removal
(Master thesis, 2022)The offshore wind market is a fast growing market. Currently, 3 GW of offshore wind are installed in The Netherlands. However, the ambitions of the Dutch government are to have 30 GW offshore wind installed by 2030. The ... -
Feasibility Study of the ECO Trawl Concept
(Master thesis, 2018)The objective of thesis is a preliminary feasibility study of the ECO Trawl Concept, proposed by ECO Trawl AS. The concept aims at replacing the traditional trawl door solution commonly used in trawling, and instead use ... -
