Autonomous navigation for unmanned surface vessels is a modern and rapidly growing field of research. In recent years, many concepts and solutions have been proposed in order to achieve autonomous control of marine vessels. ...

Denne avhandlingen presenterer et komplett system for autonom baneplanlegging, banegenerering og banefølging for et marint overflateskip. Baneplanleggeren er delt inn i en global planlegger med lav oppløsning, som planlegger ...

When ROVs are operated with manual joysticks, the user will experience a lack of control because of currents and drag forces from the umbilical. This will induce undesirable oscillations and motions that are hard to ...

Simultaneous localization and mapping (SLAM) is the twofolded problem of locating a vehi- cle starting at an unknown location and mapping the surrounding environment simultane- ously. This thesis considers the SLAM problem ...

Due to operation cost and environmental concerns, there is ongoing effort to reduce the fuel consumption and emissions in all transportation sectors including marine transportation. In the last decade, the development of ...

This paper investigates different methods for compensating the mean and slowly varying environmental loads, and unmodeled dynamics (bias loads) in dynamic positioning of marine vessels. Four different methods are compared; ...

Den økende vannmangelen truer utviklingen til både mennesker og miljøet. Avsalting av saltvann ved bruk av bølgekraft er en metode for ferskvannsproduksjon som har vært under utvikling siden 1970. Et av prosjektene er ...

In an offshore environment, offshore wind energy resources are more available and stable, but the investment cost is much higher than that of onshore wind. The installation cost is a crucial factor of the investment. With ...

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 ...
