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 new method for underwater archaeological surveying using sensors and unmanned platforms
(Journal article; Peer reviewed, 2016)As most of the world’s oceans are inaccessible to diving archaeologists, we must rely on advanced underwater technology and marine robotics to explore, map and investigate ship wrecks in these areas. New sensors and unmanned ... -
A Tension-based Position Estimation Approach for Moored Marine Vessels
(10th IFAC Conference on Manoeuvring and Control of Marine Craft;MCMC 2015, Journal article; Peer reviewed, 2015)This paper presents a novel idea on a tension-based localization approach as a redundancy measure to handle the situation when the position reference (posref) signals are not available or significant GNSS drifts occur, ... -
Adaptive Backstepping Control of Ship Speed Tracking and Hybrid Mode Selection.
(Peer reviewed; Journal article, 2021)This paper investigates the application of adaptive backstepping control to a hybrid power system for ship propulsion, using a main diesel engine in conjunction with a battery for auxiliary power supply. Fuel injection ... -
Additive Manufacturing Path Generation for Robot Manipulators Based on CAD Models
(Peer reviewed; Journal article, 2020)Traditional extrusion based additive manufacturing (AM) is realized using a 3 degrees of freedom (DOF), translation only, 3D printer. It then follows that the printer must be larger than the printed part. One way of enabling ... -
Additive or Conventional Manufacturing for Spare Parts: Effect of Failure Rate Uncertainty on the Sourcing Option Decision
(Peer reviewed; Journal article, 2022)Additive manufacturing (AM) has recently been reported as enabler of digital spare parts supply. Thanks to its promise to produce spare parts with shorter lead times, AM may enable a make-to-order rather than a make-to-stock ... -
Advances in Spare Parts Classification and Forecasting for Inventory Control: A Literature Review
(Peer reviewed; Journal article, 2021)Ensuring availability of spare parts is essential for original equipment manufacturers (OEMs) to support after-sales maintenance and repair services for their products. Previous studies have pointed out shortcomings of ... -
An On-site Current Profile Estimation Algorithm for a Moored Floating Structure
(Journal article; Peer reviewed, 2016)The current speed influences the safety of subsea and marine operations. This paper proposes an algorithm to estimate the depth-dependent current profile though data from existing commercial sensors, that is the mooring ... -
Applied Nonlinear Compressor Control with Gain Scheduling and State Estimation
(Journal article; Peer reviewed, 2018)Subsea gas compressors are key components for both increased and accelerated hydrocarbon production. Compressors enable the development of fields that are remote, in deep waters, or have low and/or reduced reservoir pressure. ... -
An Appraisal Towards the Technological Improvement of Library Operations Management in Digital Era
(Journal article; Peer reviewed, 2023)Operations management has turned into a challenging agenda for non-profitable organizations in the current competitive world. To better resolve such issue, technological and digital advancements pave the way to improve the ... -
Autonomous subsea intervention (SEAVENTION)
(Peer reviewed; Journal article, 2022)This paper presents the main results and latest developments in a 4-year project called autonomous subsea intervention (SEAVENTION). In the project we have developed new methods for autonomous inspection, maintenance and ... -
Co-creators of wellbeing - smarter engagement of older residents
(Peer reviewed; Journal article, 2021)It is acknowledged that technological innovation could help in creating individual and social wellbeing, especially as a supportive tool for seeing the benefits of “sharing is sustainable” and collaborative actions for ... -
Combining Supervised Learning and Digital Twin for Autonomous Path-planning
(Peer reviewed; Journal article, 2021)Over the last decade, the evolution of autonomous automobiles based on artificial intelligence has increased rapidly with significant success. Naturally, this has caught the interest of the maritime industry and the ... -

Comparing Controllers for Dynamic Positioning of Ships in Extreme Seas
(Journal article; Peer reviewed, 2016)This paper considers the design, implementation and experimental verification of two controllers for ship station keeping in extreme seas. In particular, the performance of two dynamic positioning controllers are compared, ... -
Conceptual design of intelligent platform for non-invasive thermal discomfort detection
(Peer reviewed; Journal article, 2022)Harsh climate conditions, events of over-heating and over-cooling created a gap between envisioned indoor environment and actual performance of the buildings. This paper suggests a potential development of the study which ... -
Continuous and discrete abstractions for planning, applied to ship docking
(Peer reviewed; Journal article, 2021)We propose a hierarchical control framework for the synthesis of correct-by-construction controllers for nonlinear control-affine systems with respect to reach-avoid-stay specifications. We first create a low-dimensional ... -
Control Considerations for Very Large Floating Wind Turbines
(Peer reviewed; Journal article, 2022)Increasingly large floating wind turbines (FWTs) are being introduced to access the offshore wind resource over deep water at lower cost. In connection with designing a 25 MW semi-submersible wind turbine, we examine the ... -
