Charles J. Vos The Netherlands

Charles J. VosProf. Charles J. Vos is managing director of Dalta Marine Consultants. He studied civil engineering at Delft University of Technology in Holland and specialised in concrete technology in a PG Diploma course at Leeds University in the UK. He served as a designer at the parent company of Delta Marine Consultants, HBG. He was responsible for the design of the DUNLIN A platform, one of the early Northern North Sea GBS structures for 160 m deep water, installed in 1977.

This raised his interest for OTEC. With Delta Marine Consultants, which he founded in 1977, several major OTEC studies were performed. A Large System Constructability Study for the USA Department of Commerce (400 MW floating unit), a land based demonstration plant on the island of Bali in Indonesia and several studies for the Island of Curacao were among these studies. Research work was carried out under his supervision on fibre type heat exchangers and on a new type cold water pipe, fit for deployment at sites requiring 100' diameter.
