Wireless charging of offshore wind service vessels
AuthorNilsen, Henrik Fjeld
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 charging operation and provides high power density. Brief time between the turbines requires high power to extend the range for the vessel between the turbines. Technical design of inductive charging systems is discussed, and the general aspect of a solution developed for power transfer in the range of 4 kW to 110 kW is proposed. Various compensations were consulted from literatures on Electric boats and wireless power technology, Series-Series (SS) was adopted due to its high-power ability. The proposed wireless charging solution has been simulated and analyzed, a small-scale prototype has not been constructed due to Covid-19.

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 ...

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 ...
