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 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 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 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 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 ... -
A Neural Network-Based Sensitivity Analysis Approach for Data-Driven Modeling of Ship Motion
(Journal article; Peer reviewed, 2018)Researchers have been investigating data-driven modeling as a key way to achieve ship intelligence for years. This paper presents a novel data analysis approach to data-driven modeling of ship motion. We propose a global ... -
A novel simulation model, BK_BiogaSim for design of onsite anaerobic digesters using two-stage biochemical kinetics: Codigestion of blackwater and organic waste
(Journal article; Peer reviewed, 2020)The design of biogas reactors for blackwater treatment provides special challenges due to significant variability in blackwater characteristics, the complexity of biological systems, and the need, in many cases, to operate ... -
A Voxel-Based Numerical Method for Computing and Visualising the Workspace of Offshore Cranes
(Chapter; Peer reviewed, 2015)Workspace computation and visualisation is one of the most important criteria in offshore crane design in terms of geometry dimensioning, installation feasibility and operational performance evaluation. This paper presents ... -
Active heave compensation of floating wind turbine installation using a catamaran construction vessel
(Peer reviewed; Journal article, 2021)The application of floating wind turbines is limited by the high cost that increases with the water depth. Offshore installation and maintenance continue to consume a high percentage of the project budget. To improve the ... -
An efficient neural-network based approach to automatic ship docking
(Journal article; Peer reviewed, 2019)Automatic ship docking is one of the applications of autonomous ships. How to realize autonomous low-speed maneuver under environmental disturbances for docking is the fundamental problem at present. This paper presents ... -
