Design and Validation of a Course Control System for a Wave-Propelled Unmanned Surface Vehicle
Dallolio, Alberto; Øveraas, Henning; Alfredsen, Jo Arve; Fossen, Thor Inge; Johansen, Tor Arne (Journal article, 2022)Unlike common marine vessels, wave-propelled vehicles cannot directly control their speed, but rely instead on the forces exerted by the environment to navigate as intended. The unique navigation capabilities of such ... -
Dynamic Positioning Using Model Predictive Control with Short-Term Wave Motion Prediction
Øveraas, Henning (Master thesis, 2020) -
Dynamic Positioning Using Model Predictive Control With Short-Term Wave Prediction
Øveraas, Henning; Halvorsen, Håkon Skogland; Landstad, Olav; Smines, Vidar; Johansen, Tor Arne (Peer reviewed; Journal article, 2023)Remotely operated vehicle (ROV) operations are today typically supported by large designated vessels. New emerging concepts aim to streamline ROV operations by utilizing unmanned surface vessels of a smaller size. Reduction ... -
ENC-based Anti-Grounding and Anti-Collision System for a Wave-Propelled USV
Dallolio, Alberto; Bergh, Thea; De La Torre, Pedro R.; Øveraas, Henning; Johansen, Tor Arne (Chapter, 2022)Wave-propelled unmanned surface vehicles (USVs) rely on the forces exerted by the environment to navigate as intended. The unpredictability of the environment and the low speed and limited maneuverability that characterizes ... -
Gain-scheduled steering control for a wave-propelled unmanned surface vehicle
Dallolio, Alberto; Øveraas, Henning; Johansen, Tor Arne (Peer reviewed; Journal article, 2022)The persistent observation of oceanographic phenomena is nowadays hampered by technological limitations, that prevent marine robotic platforms to autonomously execute scientific surveys for extended periods of time. The ... -
Monitoring the Growth of Coastal Algae Blooms in Harsh Weather Conditions Using a Wave-Propelled ASV: Challenges and Lessons Learned
Øveraas, Henning; Dallolio, Alberto; De La Torre, Pedro R.; Johansen, Tor Arne (Peer reviewed; Journal article, 2023)This article presents the experience gathered on a 19-day-long field campaign with the wave-propelled, solar-powered, autonomous surface vehicle AutoNaut. The operation was conducted in Frohavet, a semienclosed sea along ... -
Predicting the Speed of a Wave-Propelled Autonomous Surface Vehicle Using Metocean Forecasts
Øveraas, Henning; Heggernes, A; Dallolio, Alberto; Bryne, Torleiv Håland; Johansen, Tor Arne (Chapter, 2022)Wave-propelled autonomous surface vehicles are becoming increasingly popular in oceanographic research due to their ability to provide persistent observations of the ocean environment. This type of vehicles are propelled ... -
Wave motion compensation in dynamic positioning of small autonomous vessels
Halvorsen, Håkon Skogland; Øveraas, Henning; Landstad, Olav; Smines, Vidar; Fossen, Thor I.; Johansen, Tor Arne (Peer reviewed; Journal article, 2020)Conventional dynamic positioning (DP) systems on larger ships compensate primarily for slowly time-varying environmental forces. In doing so, they use wave filtering to prevent the DP from compensating for the first-order ...
