Cooperative Research Ships celebrates 50th anniversary!

As Cooperative Research Ships (CRS) celebrates its 50th anniversary, we talk to some of MARIN’s key figures – both past and present - about this unique alliance, which has carried out more than 100 ground-breaking projects.

Marinus Oosterveld, former President of MARIN, joined the research institute in 1961. In 1969 two of the ‘CRS founding fathers’ – Kockums
shipyard of Malmö (Sweden) and Chantiers de l’Atlantique of St. Nazaire (France) – asked him to organise the first formal CRS event. Marinus became the first chairman of CRS until his retirement in 1996.

Jan Blok joined MARIN in 1974 and has been involved in numerous CRS working groups. In 2004 he was appointed Secretary of CRS. He worked within the organisation until his retirement from MARIN in 2009.

Do spent his early career with propeller company Lips and he then joined MARIN in late 1978. He was a member of the CRS community on behalf of Lips in 1977 and 1978, and continued this on behalf of MARIN from 1979 to 1997. Do specialised in cavitation and related topics, and moved back to Lips (taken over by Wärtsilä in 2002) from 1998 until 2013, re-joining CRS from 2005 on. After his early retirement from Wärtsilä he became a part- time consultant on propellers and cavitation at MARIN, and officially retired in August 2018.

Ed van Daalen is the current CRS Secretary and senior researcher at MARIN.
