Selv om fiskeri- og havbruksnæringene er anerkjent som viktige bidragsytere til den globale produksjonen av sjømat, er de imidlertid også kjent for å ha større HMS-utfordringer og jobbrelaterte skader enn andre industrisegmenter. En økning av automasjonsnivået i gjennomføringen av...

Fisheries and fish farming are important global contributors to the production of seafood for human consumption. These industries are also known for substantially higher HSE risks and work-related injury frequencies which implies that increasing the automation level of high-risk operations within...

An integral version of the line-of-sight guidance method is shown to compensate for both kinematic and dynamic disturbances generated by wind, waves and sea currents. The guidance law is designed for path following tasks of underactuated marine vessels moving in the horizontal plane. Specifically...

The ARTIFEX project aims at developing robots for remote and/or autonomous inspection, maintenance and repair (IMR) operations at fish farms. An unmanned surface vehicle (USV) is used as a platform for carrying a remotely operated vehicle (ROV) for underwater operations and a remotely piloted...

A control technique for counter-current and co-current guidance of underactuated marine vehicles is revisited and stronger stability properties are shown. In particular, the stronger property of uniform semiglobal exponential stability is shown for the complete multiple-equilibria closed loop system...
