What made you get involved in CRS originally?

Olav Rognebakke, Chairman of RAW++ (Added Resistance in Waves) and Head of Section at DNV GL: “I was brought along to a meeting in the first year of joining my company. I wanted to get to know some people. It was quite an experience and that was already 12 years ago!”

Tobias Huuva, Chairman of SHARCS2 (CFD for Cavitation) and Manager Core Competence Team at Caterpillar Propulsion: “For me it was 10 years ago when I was working at Berg Propulsion and at that time I was looking at propeller analysis. I met some people from MARIN who stressed that they had a much better tool than I was considering. And it showed that we had to join CRS to get this fantastic tool called PROCAL!”

Loic Morand, Chairman of SPEED2DESIGN (CFD for Powering) and Head of the Hydrodynamic Department at Chantiers de l’Atlantique: “My first meeting was back in 1999 when I was introduced into a working group by Roger Lepeix.”

In CRS, each project starts with an idea, followed by an initiative. Can you describe the path from conception to a mature project for your working group?

Olav: “RAW++ is a continuation of another working group. My own company and MARIN had a real passion for this topic so we joined forces for the first project, made a proposal and started to get others on board, making sure we had support. This process is an important part of CRS, setting out projects, lobbying and getting people around the table.”

Tobias: “SHARCS2 is also a continuation, we have been going for six years now. We presented the proposal about cavitation simulations to bring in more people and it is working very well.”

Loic: “The original idea for SPEED came from Raimo Hamalainen, now Head of Hydrodynamics at Meyer Turku, who asked me to chair.”

Olav: “This process of using an existing working group and sitting together to make sure there is a continuation of the research is at the heart of CRS.”

Tobias: “We make sure all members are listened to and have a chance to voice their opinion. This is important to have this climate in the group.”

CRS currently has 23 members which can be divided into ‘blood groups’: research institutes, shipyards, class societies, suppliers and operators. Is this mix reflected in your working group?

Tobias: “In SHARCS2 I think we have 4-5 ‘blood groups’. This is important because

you need some people to evaluate, some to analyse and some need deeper knowledge. This all broadens the research and brings input from different fields of the marine world to give insight into problems.”

Loic: “Our members bring wide ranging views about the problem, we have different people from a range of organisations. Some people have very good theoretical ways of solving the problems. In parallel, we need people who are very pragmatic. We manufacture products that are not so simple, so the confrontation between these different people is very interesting!”

CRS is based on active participation of the members. How does this work for your working group and can this be improved?

Loic: “Sometimes the meetings can mean only a few people discussing special topics and then some members feel a little left out.
