Purpose – The purpose of this paper is to describe the design and function of Fred. Olsen's wave energy converter (WEC) system Lifesaver with special focus on the stand-alone electrical system that is implemented for operation without grid-connection. Design/methodology/approach – The paper focus on the detailed design of the DC-Link system that drives the industrial 400 VAC inverters and generators for the production system. The DC-Link is stabilized by an ultra capacitor bank and has no external source or grid-connection. Findings – The system has been tested through extensive sea trials since April 2012 and has proved its function. Some results from real sea testing are presented. Practical implications – This paper proves the viability of the specified design and may serve as a basis for the design if similar systems in the future. Originality/value – This paper presents a WEC system that has proven successful operation through practical tests, and is therefore regarded as a high-value paper as there is limited experience on this subject.
