AMOS DP Research Cruise 2016: Academic full-scale testing of experimental dynamic positioning control algorithms onboard R/V Gunnerus
(Chapter; Peer reviewed, 2017)In order to validate relevant dynamic positioning (DP) control algorithms in a realistic environment, a full-scale DP test campaign, the AMOS DP Research Cruise 2016 (ADPRC’16), was organized in a collaboration between the ... -
Automatic image segmentation for boundary detection of apparently connected sea-ice floes
(Chapter, 2013)Ice concentration, ice types, and floe size distribution are three important factors in the analysis of ice-structure interaction in a broken ice field. The use of cameras as sensors for offshore operations in ice-covered ... -
Comparison of Fuel Consumption on a Hybrid Marine Power Plant With Low-Power Versus High-Power Engines
(Chapter, 2018)In this paper, we are comparing fuel consumption on a case study hybrid marine power plant with diesel gensets and batteries. Optimization methods are used to find an optimal operating point for the gensets, under different ... -
Distributed sensing of loads acting against the hull of a stationkeeping vessel in ice
(Chapter, 2018)This paper introduces the concept of distributed motion sensing for stationkeeping vessels in ice infested waters. During the SKT 2017 project, conducted in February and March 2017 in the Bay of Bothnia, five inertial ... -
Optimal Online Configuration and Load-Sharing in a Redundant Electric Power System for an Offshore Vessel Using Mixed Integer Linear Programming
(Chapter, 2018)This paper proposes several schemes for optimal online configuration and load sharing for a shipboard power system of a typical offshore vessel, having a number of varying capacity gensets. Different methods are presented ... -
A phase-time-path-difference approach for online wave direction and wave number estimation from measured ship motions in zero and forward speed using a single inertial measurement unit
(Journal article; Peer reviewed, 2023)This study investigates the potential capability of a relatively new and unexplored signal-based approach for shipboard wave estimation. The approach uses the phase-time-path-differences (PTPDs) from an array of shipboard ... -
A Resetting Observer for Linear Time-Varying Systems with Application to Dynamic Positioning of Marine Surface Vessels
(Journal article; Peer reviewed, 2024)This brief presents a resetting observer for linear time-varying (LTV) systems. The motivation for the observer is better handling of unmodeled dynamics and reactiveness to external disturbances without compromising ... -
A survey on modeling and control of thruster-assisted position mooring systems
(Peer reviewed; Journal article, 2020)This review presents a systematic summary of the state-of-the-art development of technological solutions, modeling, and control strategies of thruster-assisted position mooring (TAPM) systems. The survey serves as a starting ...
