3D Reuse in PLM for Conceptual Ship Design
(Master thesis, 2017)Today 3D CAD tools have become more and more used in design processes, allowing amongst other better visualization of product, computer analysis of design, etc. Even so, in ship design, 3d-design is still combined with 2D ... -
A Benchmarking Framework for Control Methods of Maritime Cranes Based on the Functional Mockup Interface
(Journal article, 2017)A benchmark framework for advanced control methods of maritime cranes is presented based on the use of the functional mockup interface. The system integrates different manipulator models, all the corresponding hydraulic ... -
A bézier curve based ship trajectory optimization for close-range maritime operations
(Chapter, 2017)Ship maneuvering in close-range maritime operations is challenging for pilots, since they have to not only prevent the ship from collisions and compensate environmental impacts, but also steer it close to the target towards ... -
A Bio-inspired Swimming Robot Concept Design for Marine Aquaculture Applications
(Master thesis, 2014)In this master thesis project, a concept design of bio-inspired swimming robot is developed for marine aquaculture applications. According to the requirements from the marine aquaculture industry, the manta ray is selected ... -
A Closed Loop Inverse Kinematics Solver Intended for Offline Calculation Optimized with GA
(Journal article; Peer reviewed, 2018)This paper presents a simple approach to building a robotic control system. Instead of a conventional control system which solves the inverse kinematics in real-time as the robot moves, an alternative approach where the ... -
A Comprehensive Survey of Prognostics and Health Management based on Deep Learning for Autonomous Ships
(Journal article; Peer reviewed, 2019)The maritime industry widely expects to have autonomous and semiautonomous ships (autoships) in the near future. In order to operate and maintain complex and integrated systems in a safe, efficient, and cost-beneficial ... -
A CONDITION BASED, RISK ANALYSIS AND LIFE CYCLE ORIENTED APPROACH FOR LIFE EXTENSION OF FPSO UNITS
(Master thesis, 2020)Denne masteroppgaven foreslår en metodikk for et FPSO livsforlengelsesprosjekt og tester den ut for et fiktivt fartøy. Metodikken er utviklet basert på at enhetens tekniske tilstand, restverdi, prosjektrisikoer og behov ... -
A coupled modeling of design and investment parameters for optimal operation of methane bioreactors: Attainable region concept approach
(Journal article; Peer reviewed, 2020)Current practice to design methane bioreactors does not consider all degrees of freedom simultaneously, which raises question of global optimality. This study presents a model-based design framework, which simultaneously ... -
A decentralized sensor fusion approach to human fatigue monitoring in maritime operations
(Chapter, 2019)Human fatigue is one of the main causes of accidents in maritime domain. How to use physiological data to estimate degree of human fatigue without medical domain knowledge is significant to the safety of tasks in maritime ... -
A Generic Modelling Approach for Heavy Lifting Marine Operation
(Master thesis, 2014)This thesis project introduced a generic modelling approach for heavy lifting marine operation based on 20-sim simulation and Matlab control. The model is a multi-body dynamic system which can be divided into vessel, crane, ... -
A human perspective on maritime autonomy
(Journal article; Peer reviewed, 2018)As for all of the transport segments, autonomy is gaining increasing interest by researchers and for development in the maritime industry, and introducing autonomy is expected to create new possibilities to increase ... -
A Knowledge-Based Approach for an Open Object Oriented Library in Ship Design.
(Master thesis, 2016)A vessel is a complex and integrated system, which is composed by several subsystems and parts which can have common interfaces and interact in a non-linear way. With the continuous development of ship design techniques, ... -
A Language and Platform Independent Co-Simulation Framework Based on the Functional Mock-Up Interface
(Journal article; Peer reviewed, 2019)The main goal of the Functional Mock-up Interface (FMI) standard is to allow the sharing of simulation models across tools. To accomplish this, FMI relies on a combination of XML-files and compiled C-code packaged in a zip ... -
A method for estimation of equivalent-volume ice thickness based on WMO egg code in absence of ridging parameters
(Journal article; Peer reviewed, 2018)When calculating equivalent-volume ice thickness along a vessel's projected route for the purpose of ice resistance estimation, information on both undeformed ice (level ice) and deformed ice (mainly ridges) is needed. ... -
A multi-body dynamic model based on bond graph for maritime hydraulic crane operations
(Chapter; Peer reviewed, 2015)This paper presents a bond graph model of a maritime crane lifting system comprised of a 3DOFs crane with three revolute joints, a winch, a segment of wire, and a pendulum load. The multi-body model contains the dynamic ... -
A multi-sensor fusion framework for improving situational awareness in demanding maritime training
(Journal article, 2017)Real offshore operational scenarios can involve a considerable amount of risk. Sophisticated training programmes involving specially designed simulator environments constitute a promising approach for improving an individual's ... -
A Neural Network Approach to Control Allocation of Ships for Dynamic Positioning
(Journal article; Peer reviewed, 2018)Dynamic Positioning (DP) of ships is a control mode that seeks to maintain a specific position (stationkeeping) or perform low-speed maneuvers. In this paper, a static Neural Network (NN) is proposed for control allocation ... -
