Sammendrag
This paper evaluates and tests the HUGIN 1000 HUS AUV as a carrier platform for the Laser
Optical Plankton Counter (LOPC). The LOPC was mounted outside on top of the carrier
platform, and the tests confirm that this concept did not create turbulence and zooplankton
avoidance. A negligible velocity difference between the flow passing through the sampling
tube and the AUV speed was detected. The abundance recorded by the LOPC onboard
HUGIN 1000 HUS was within the same order of magnitude compared to the zooplankton
abundance from traditional net-based measurements. Our results showed zooplankton
abundance in the range of 70 to 180 individuals m-3, while other, traditional net-based
measurements have indicated 27 - 332 individuals m-3 from the same area and same depth
layer. Note that these numbers are minimum and maximum values observed from a vast
number of samples. The mean is approximately 200 individuals m-3.
The results provide new and unique high-resolution biological data of deep-water copepod
communities. The application of AUVs in marine ecological research introduces advanced
methodology with potential to address new scientific questions in deep water habitats.

Innovation and commercialization potential of university-developed arctic ice-tethered platforms. A case study of research-based technology
Agwu, Ukeje Jacob; Logvinovskaya, Anna; Phetchpinkaew, Gorn (Master thesis; Mastergradsoppgave, 2017-05-31)The Arctic is a region which is rapidly opening up for business opportunities. However, research has been abundant here for a long time. With this situation comes the avenue to transition technology used in the region from research to commercial purposes. In this thesis, a business case is developed to show the commercial potential of research-based technology. The case technology was developed by ... -
Wireless charging of offshore wind service vessels
Nilsen, Henrik Fjeld (Master thesis; Mastergradsoppgave, 2021-05-18)This report discusses the possibility for wireless charging solutions for electric vessels, with a focus on offshore wind turbine service. Where the charging time is minimal and safety for crew is important. Different types of wireless technologies have been studied, where the Inductive power transfer (IPT) is shown to be the preferred technology. Inductive power transfer (IPT) grants a safe ... -
The Future of Solar Energy in Marine Applications
Dahlen, Sigurd (Master thesis; Mastergradsoppgave, 2018-06-01)The objective of this master's thesis is to investigate the current and future technical and economic feasibility of PV systems for marine applications. Two scenarios will be studied; a land-based PV power station to supply an in-land ferry in Norway and a PV system installed on a wind farm support vessel as a supplementary power source. The two scenarios are use cases that support the two research ...
