Improved safety at sea for cruise ship passengers and crews will be the outcome of a research and development project, funded with the help of over €1.7m (euros) from the EU’s Framework Programme.
SEA-AHED (Simulation environment and advisory system for on-board help, and estimation of manoeuvring performance during design) was a 39-month project to produce a technology system that can predict the course of cruise ships within 10 to 20 metres - far more accurately than anything currently available commercially.
Today’s super-cruisers have the capacity to carry over 4,000 people so any collision has the potential to produce unprecedented carnage. SEA-AHED can help to significantly reduce the risk of this happening and can also contribute directly to safety through on-board training. It is capable of providing situational awareness and predicting the behaviour of the vessel in situations where some machinery fails. Safety of both the passengers and the ship makes it essential that the pilot be given the best possible information regarding the consequences of any manoeuvring actions. It also demands that he be automatically alerted with all speed in case of looming hazards.
The system takes account of wind speed, wind direction, water depth, currents, actual rudder angles, demanded rudder angles, thruster performances, etc. and consider the non-linear and time-varying manoeuvring characteristics of the vessel. It also exploits very recent advances in aerospace and robotics applications using a technique called the Julier-Ulhmann filter.
Current systems generally rely on constant rate models that do not provide the accuracy necessary for safe operation and the project consortium claim that, for the non-linear models under consideration, SEA-AHED far outperforms the industry standard extended Kalman Filter. “Safety has to be the number one priority for cruise ships with the continually growing number of passengers”, says Cliff Funnell Cliff Funnell, FP6UK National Contact Point for Surface Transport (Maritime). “SEA-AHED is an excellent example of the type of project Framework Funding is provided for and, as this contributed 50 per cent of the total €3.4 m (euros) project cost, it seems fair to assume that without it the project would not have been viable.
“The current Framework Programme (FP6) runs until 2006 and organisations wanting free, easy to access, information on the €19bn of funding available to support internationally collaborative R&D should log on to http://fp6uk.ost.gov.uk or call central telephone support on 0870 600 6080.”
Project partners are predicting that SEA-AHED will create the demand for at least two more vessels - expected to secure around 2,300 jobs – as well as bringing considerable commercial benefits throughout the industry. This includes:
The possibilities opened up by research on the SEA-AHED project may also be extended to bulk carriers, tankers, container ships, Roll On-Roll Off and fast ferries by lending itself towards the development of intelligent cruise control, and automatic docking for these large vessels.
Other possibilities for future research include prediction and obstacle avoidance for commercial fixed wing aircraft, intelligent cruise control for cars, and automated underwater vehicles.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
