Natural Propulsion seminar (2012)
For almost 80 years MARIN has been involved in optimizing hull forms to reduce resistance and fuel consumption. Today the same techniques are still being used but with additional emphasis on reducing emissions and the impact on the environment. A radical change in propulsion sources could be considered as alternative to engine driven ships: Natural Propulsion.

The use of environmental forces such as wind, waves, current or sun has always been at the heart of maritime transport. Today, high energy prices and the increasing pressure on environmental protection, is giving new life to many ideas and a certain boost to radically new developments in propulsion sources.

Natural Propulsion Seminar
In order to sustain such initiatives and share potential technical and concept opportunities and to outline upcoming challenges, MARIN organised a succesful Natural Propulsion seminar last January.

More than 100 academics, scientists, naval architects, shippers, entrepreneurs and innovators gathered to share the latest developments and opportunities in means of natural propulsion at sea.
Whilst some content featured auxiliary power produced by liquid bio-methane fuelled engines, the overwhelming short term solution offered by all speakers was to utilise the wind.

Read here a complete run-down of the seminar. Below you find the presentations.
