A nuanced update on maritime technology
Just like in previous issues, the 2005 edition of the Scandinavian Yearbook of Maritime Technology brings a nuanced choice of the latest in maritime technology:

Lena Blomqvist of Wallenius Wilhelmsen writes about climate change, the biggest threat to our environment. She also presents the E/S Orcelle and gives us an idea of what the truly zero emission ship of tomorrow might look like.
Oskar Levander of Wärtsilä believes that wing thrusters will be propelling the next generation of ferries.

Kjeld Aabo of MAN B&W in Copenhagen, another large diesel engine supplier, writes about the low speed diesel solution in LNG carrier propulsion.
Quite a few maritime issues have been addressed when LNG offloading have been envisaged in inshore LNG terminals and jetties. Johan H. de Jong and Jos van Doorn of the Maritime Research Institute, Netherlands, have looked into the problem and give us their ideas on LNG shipping safety around ports and terminals.

In their paper Rough waves – simulation and impact on marine structures, Christian Schmitter, Sascha Kosleck and Guenther Clauss with the Ocean Engineering Section, Technische Universität, Berlin, describe new methods for the generation of tailored wave sequences for model tests, which will help us protect vessels and offshore structures from the raw force of the sea.

The award winning Cylmate System, working with pressure transducers that make it possible to constantly measure the combustion pressure in large two-stroke engines, is described by Lars Karlsson of ABB Automation Technologies AB.

If your ship is equipped with old cargo and ballast automation it might be a good idea to look for a retrofit. In Shipmaster – a way out of murky waters, Andreas Madsen of Kockum Sonics and Kjell Arnesen of Karismar Mariner Systems develop the advantages of a new operating system.

To be competitive in today’s market, ports must meet the demands on cost and performance by the different operators. Linda Styhre of SSPA writes about the intermodal seaport and the new approach to waterborne transportation.

The next generation of large containerships brings challenging design issues and in Design issues critical to the next generation of large containerships, Wei-Biao Shi of ABS writes about the Dynamic Loading Approach for evaluating structural performance of the ultra-large designs.

In Saving money and environment with variable speed compressors, Marit Holen and Egil Norderhaug of Tamrotor Marine show that variable speed compressors can contribute to a substantial decrease in energy consumption.

Jan-Åke Jönsson of the World Maritime University in Malmö writes about how the hull form influences the stability of ships.

Daniel Flodén of SSPA Sweden AB believes that the optimized trimaran conceptual design represents a new transport solution which is logistically efficient, more environmentally friendly and also highly efficient in performance in the North Sea trade. In The performance of a trimaran in comparison with a monohull, he explains and develops the idea.

How big is a vessel really? Well, that depends on how you measure it. In Tonnage regimes in shipping: a critical over-view, Yakabe Fumi of the Ministry of Land Infrastructure and Transport in Tokyo gives us a useful lesson.

In designing, constructing and operating large cruise ships, Ray Essén and Peter Albrecht of Elomatic put forward an interesting question: how big can a cruise ship be and what factors are vital to its development?

In A flying start in China for FKAB/DF-Marine, Peter Rösholm of DF-Marine and Niklas Lindvall of DNV Software write about their experience of working in China and how the Chinese shipyards are developing, as well as what tools and experience are available in China today.

I hope the articles presented in this Yearbook will fulfil your expectations and give you an idea of what the maritime industry is working on today and the challenges of tomorrow.
