The BYEFOULING project will address high volume production of low toxic and environmentally friendly antifouling coatings for mobile and stationary maritime applications. The technology will fulfil the coating requirements as a result of the incorporation of novel antifouling agents and a new set of binders into coating formulations for maritime transportation and fishing vessels, floating devices and aquaculture. The main vision of BYEFOULING is to provide the means for industrial, cost-effective and robust manufacturing of antifouling coatings in Europe, where SMEs are both coating components developers and production technology providers. A set of procedures, guidelines and fabrication tools will be developed, enabling short time to market for new coating concepts. The main goal of BYEFOULING is to design, develop and upscale antifouling coatings with enhanced performance compared to current available products. The approach in BYEFOULING is to tackle the different stages of the biofouling process using innovative antifouling agents, covering surface-structured materials, protein adsorption inhibitors, quorum sensing inhibitors, natural biocides and microorganisms with antifouling properties. Encapsulation of the innovative compounds in smart nanostructured materials will be implemented to optimize coating performance and cost all along their life cycle. A proof-of-concept for the most promising candidates will be developed and demonstrators will be produced and tested on fields. BYEFOULING will combine a multidisciplinary leading research team from 11 European countries, which are already acting worldwide in the scientific community, with highly relevant and skilled technological partners, to build a consortium able to develop a full production line for antifouling coatings in Europe. Readily available low toxic and cost-effective antifouling coatings will increase the efficiency of maritime industry and be the enabling technology to realize new products.

The core concept of Accelerated Metallurgy is to deliver an integrated pilot-scale facility for the combinatorial synthesis and testing of many thousands of unexplored alloy formulations. This facility would be the first of its kind in the world and would represent a significant advance for metallurgy. The novel technology that enables this HTT facility is based on automated, direct laser deposition (DLD). The key feature of this technology is the way in which a mixture of elemental powders is accurately and directly fed into the lasers focal point, heated by the laser beam, and deposited on a substrate in the form of a melt pool, which finally solidifies to create a unique fully-dense alloy button with precise stoichiometry. This robotic alloy synthesis is 1000 times faster than conventional manual methods. Once produced, these discrete mm-sized samples are submitted to a range of automated, standardised tests that will measure chemical, physical and mechanical properties. The vast amount of information will be recorded in a Virtual Alloy Library and coupled with computer codes such as neural network models, in order to extract and map out the key trends linking process, composition, structure and properties. The most promising alloy formulations will be further tested, patented and exploited by the 20 end-users. Industrial interests include: (i) new lightweight fuel-saving alloys (<4.5 g/cm3) for aerospace and automotive applications; (ii) new higher-temperature alloys (stable>1000C) for rockets, gas turbines, jet-engines, nuclear fusion; (iii) new high-Tc superconductor alloys (>30K) that can be wire-drawn for electrical applications; (iv) new high-ZT thermoelectric alloys for converting waste heat directly into electricity; (v) new magnetic and magnetocaloric alloys for motors and refrigeration; and (vi) new phase-change alloys for high-density memory storage. The accelerated discovery of these alloy formulations will have a very high impact on society.

The properties of linepipes are measured by tensile tests in the main loading direction. The designer can on the base of this information assess the reliability of the pipe. However, plastic deformation is often introduced at different stage of the life of the material, from the processing to the service life, passing through the steps of testing and laying. When plastic deformation is applied, generally the yield surface of the material is modified and a non isotropic and non-symmetric behaviour should be expected. The present investigation focuses on the consequence of deformation in the hoop direction. Different materials were tested at different levels of pre-deformation in successive compression and tensile mode. The evolution of the kinematic and isotropic hardening was deduced on basis of the different experiments and modeled with an adequate constitutive law. The model is then validated by different experiments (flattened tensile specimen, ring expansion, bending). The difference of loading path for different applications is then discussed: measured yield stress on pipe for welded pipes, eventual burst pressure, and collapse of off-shore pipelines. The results of the different calculations indicate that, although the plastic deformation, if kept reasonable, does not significantly alter the properties of the material, it can have engineering consequence as the yield stress is influenced by the fabrication and the loading direction.

A pipe for a pipeline installation includes a UV-cured coating on the inner surface of the pipe, the coating having been obtained by UV-curing a coating composition including at least the following components: one or more oligomers, being photocurable (meth)acrylate resins; one or more (meth)acrylate monomers; one or more adhesion promoters; iron oxide or more photopolymerization initiators. A liquid coating composition may be applied to the interior surface of a pipe and cured.
