Climate
change – the biggest threat to our environment
Lena Blomqvist, Wallenius Wilhelmsen:
Reducing emissions into the sea and air by relying on low sulphur
fuels, biocide-free anti-foulants and ballastwater treatment is
far from enough. Fossil fuel driven engines are yesterday’s
technology and to reach a zero impact on the environment we need
ballast-free ships powered by sun, wind and waves.
A flying start in China
for FKAB/DF-Marine
Peter Rösholm, DF-Marine in Dalian/Shanghai, and Niklas Lindwall,
DNV Software: How is it to work in China? How are the Chinese shipyards
developing? What can Swedish ship owners ordering in China expect
and what tools and experience are available today?
Shipmaster – a way out
of murky waters
Andreas Madsen, Kockum Sonics AB, Sweden, and Kjell Arnesen, Karismar
Mariner Systems, Norway: Is your old automation system becoming
a problem? Then Shipmaster cargo and ballast system is a way out
of murky waters.
Saving money and environment
with variable speed compressors
Egil Norderhaug and Marit Holen (red), Tamrotor Marine Compressors
AS: The use of variable speed compressors can contribute to a substantial
decrease in energy consumption. For ship owners this not only means
they contribute to a “greener world”, but also the fuel
consumption – and thereby energy costs – are substantially
reduced.
LNG carrier propulsion –
the low speed diesel solution
Kjeld Aabo, MAN B&W Diesel A/S: Compared with the traditional
turbine, the two-stroke diesel engine in LNG carriers has a superior
terminal efficiency. The diesel solution also gives a significant
reduction of CO2 emission and a calculated reduction in operating
costs.
LNG shipping safety around ports and terminals
Johan H. de Jong and Jos van Doorn, MARIN (The Maritime Research
Institute Netherlands): Quite a few maritime issues have to be addressed
when LNG offloading is envisaged in inshore LNG terminals and jetties.
The intermodal seaport
and the new approach
to waterborne transportation
Linda Styhre, SSPA Sweden AB: The market in which ports are operating
has been substantially changed during the last two decades. To be
competitive today, ports must meet the demands on cost and performance
by the different operators.
Fluctuation in cruise vessel size.
Designing, constructing
and operating large cruise ships
Ray Essén and Peter Albrecht, Elomatic: The sizes of Cruise
Ships and Liners have constantly grown and a number of post-panamax
vessels have been built. How large can a cruise ship be and what
factors are vital for the development?
Influence by the hull form
on the stability of ships
Jan-Åke Jönsson, World Maritime University, Sweden: The
stability of a ship depends both on the location of centre of gravity
and the shape of the hull. It is easy to realize that the higher
the centre of gravity is, the less stable the ship will be. But
how is the stability affected by the shape of the hull? There is
an old saying that a nice looking and beautiful ship is also a safe
ship.True or not?

Tonnage
regimes in shipping:
a critical overview
Yakabe Fumi, Ministry of Land
Infrastructure and Transport, Japan:
How do you determine the size of a ship? Well, it is solely a matter
of how you go about it.
Cylmate Systems – award winner
Lars Karlsson, ABB Automation Technologies AB: Cylmate pressure
transducers makes it possible to constantly measure the combustion
pressure in large two-stroke engines.
Wing Thrusters propelling
the next generation of ferries
Oskar Levander, Wärtsilä Corporation:
Wärtsiläs new Wing Thruster propulsion concept offers
clear advantages. Together with Coded machinery it offers lower
operating costs and only marginally increased investment costs.
Wing Thruster propulsion with mechanical drive has both lower fuel
oil consumption and lower investment costs compared to a twin-shaft
arrangement.

Rough
waves – simulation and impact on marine structures
Christian Schmittner, Sascha Kosleck and Guenther Clauss, Technische
Universität Berlin: How high and dangerous can a monster wave
be and what can we do to protect vessels and offshore structures
from the raw force of the sea? The Ocean Engineering Section of
the Technical University, Berlin, is developing new methods for
the generation of tailored wave sequences for model tests.
The performance of a trimaran
in comparison with a monohull
Daniel Flodén, SSPA Sweden AB:
The optimized trimaran conceptual design represents a new transport
solution, which is logistically efficient, more environmentally
friendly and also highly efficient in performance on the North Sea
trade.
Design issues critical to the next generation
of large containerships
Wei-Biao Shi, ABS: The next generation of large containerships poses
challenging design issues that cannot be adequately addressed by
prescriptive classification society rules or simplified structural
analysis methods. The ABS SafeHull Dynamic Loading Approach for
evaluating structural performance of these ultra-large designs offers
efficient engineering solutions.
