European Shipyards Can Become Competitive and More Environmentally Friendly

12.10.2004


Shipyards throughout Europe could become more competitive, and help the environment, by moving away from welding and using adhesive bonding for joining lightweight materials. That is the result of BONDSHIP, a major initiative to funded with €4.6 million (euros) under the Sustainable Surface Transport programme of the EU’s Framework Programme.



The aim of the project was to achieve considerable cost savings in the production and operation of more fuel-efficient passenger ships, ferries and high-speed craft and so make European shipyards more competitive. The added benefit of adhesive bonding is that it will also make positive contributions to the preservation and improvement of the quality of the environment by reducing the amount of welding slag created.

From studies carried out in the project group, it was estimated that adhesive bonding would provide a cost saving of at least 20% for fastening of supports, stiffeners and other attachments in outfitting of large passenger ships. For a patrol craft reductions in building costs through the use of adhesive bonding in the superstructure can be expected to be around 25 to 30%. For fast ferries, another important benefit is a weight reduction of the structure by about 4.5 to 9 tons.


Over a period of 20 years these weight savings can save between 8,000 to 16,000 tons of diesel. At current fuel prices this saving is worth about 1.6 to 3.2 million euros.

“Adhesive bonding will have a significant impact on current shipbuilding practice of passenger ships”, says project co-ordinator Ajay Kapadia, form VT Composite Technology Centre. “It will trigger considerable future development far beyond the scope of the project by opening up new possibilities for all types of modular construction.

“Shipyards will benefit further by increasing the flexibility within their build schedule as they will be able to use subcontractors to produce the modules. In addition, shorter time between the signing of the contract and delivery of the vessel will help open up new opportunities for SMEs (Small and Medium Sized Enterprises) to provide services to shipyards.

“The environmental benefits are also likely to be substantial. It has been estimated that a medium size shipyard produces about 60 tons per year of welding slag - considered special waste for which a controlled disposal is required. To help reduce this significantly, the focus of the project was on aluminium-aluminium, aluminium-steel and aluminium-composite joints.”

The widespread use of adhesive bonding should also lead to considerable improvements of the working conditions in production. This is because the units are made in environments with controlled temperature, humidity and light and with improved ergonometry by allowing easier access and no overhead work. Bonded connections are straight and do not usually require rework, unlike welding of aluminium where filling and sanding work is needed. Additionally, by replacing welding with adhesive bonding welding fumes and potential fire hazards or explosions (particularly during repair) due to the welding heat are eliminated.

“BONDSHIP is a perfect example of how Framework Funding is being used to bring together expertise from across the EU to help make our industries more competitive”, says Cliff Funnell, FP6UK National Contact Point for Surface Transport (Maritime). “The project brought together 13 partners from seven Member and Associated States and the results will be of benefit to shipbuilders and businesses in other construction sectors.”

“The current Framework Programme (FP6) runs until 2006 and organisations wanting free, easy to access, information on the €19bn (euros) 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.”

The main results of the BONSHIP project are:
· guidelines for design and modelling of joints
· acceptance tests and criteria
· test and inspection methods for joints
· documented application cases and joint designs
· material data
· repair guidelines
· documented production and assembly procedures
· practical experience and skills from using adhesives in a shipyard.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
