la Jules Verne
A spectacular platform has been designed
to drift across the oceans of the world with the aid of the currents
and the wind.

This unique creation known as the “Sea Orbiter”
has been designed by the famous French architect Jacques Rougerie.
The design suggests the fantastic world of Jules Verne, and in fact
a three-metre high model of the vehicle, built by MARINTEK in Trondheim,
has actually been sent to the Jules Verne Exhibition in Paris.
MARINTEK marketing manager Kjell Holden,
who was at the exhibition's opening at the end of May 2005, said
the event attracted thousands of people, and that he hoped the presence
of MARINTEK and SINTEF made a good impression.
The real vessel will be 51 metres high, with a beam of 10-15
m. About two-thirds of it will be underwater, and that part will
contain various types of laboratories for studies of the climate,
and marine life and resources.
MARINTEK has built a model of the “Sea Orbiter”
vessel and has tested it in the Ocean Basin at the Institute.
“It is essential to have a really stable
platform, since people will be working and spending a lot of time
there. It is important to develop a platform where the crew will
not be seasick from lots of small movements and accelerations,”
During the Ocean Basin tests changes were
made in the size of the fins that protrude from the hull of the
craft and small “thruster” propellers were also tested to reduce
“We managed to improve the movement of the
platform in wave height of 7-10 metres to a level that would make
it acceptable to stay aboard for longer periods” Holden said.
The upper part of the Sea Orbiter will be
a scientific station for studies of the climate and changes in water
and the atmosphere. The station will make wave measurements and
calibrate the precise position of satellite trajectories. The underwater
part of the new vessel will be equipped with a fish-collection system
for studies of the pelagic ecosystem, plankton biodiversity and

The unique vessel will take two years to
cross the seas, and will provide a number of new ways of making
continuous observations. For the 16 member crew who will live on
board during cruises, it will be a trial just to live in such a
confined space, with so many other people. The challenges involved
will be akin to living on board the space shuttle.
Many people have also stressed the international
aspects of the project, which includes collaboration with scientists
and other experts from all over the world. It is also hoped that
sheer adventure offered by cruises such as these will awaken curiosity
about the ocean in the younger generation.
Both NASA and ESA are interested in taking part in the project,
since it will be possible to enter the sea from the lowest part
of the vessel. Tasks such as turning bolts and replacing modules
underwater while wearing neutral buoyancy diving suits is much like
moving around in space, and is good training for astronauts.Working
in neutral buoyancy, whether in a vacuum or water, means that you
Holden says that training astronauts underwater
is not a new idea. NASA has training bases outside Florida, and
Scott Carpenter – one of the first US astronauts - is on the Sea
Orbiter team. Carpenter was the first, in 1964, to promote the idea
of astronaut training underwater. In the early 1990s MARINTEK also
sought to use its own Ocean Basin as a space research laboratory.
SINTEF health researchers were also involved at with plans for temperature
studies and isolation rooms.
“For us at MARINTEK, the project is interesting, visionary
and important for the exploration of the oceans.We have learned
a great deal and made many good international contacts in several
industries.We are being brought into a network of contacts with
interesting possibilities” says Holden, who is already involved
in new plans with architect Jacques Rougerie.
