Study of the appropriateness and the adequacy of modern materials for offshore fish cage nets – numerical and experimental investigation in realistic loading conditions (MATISSE)
MATISSE is a 36 months national project starting in summer 2019 and has a budget of about 200.000€.
The project concerns the adequacy of modern materials for fish cage nets to be used in systems of offshore aquacultures. Those systems provide a variety of advantages and benefits compared to the traditional coastal aquacultures. Nevertheless, the installation and the materialization of such systems is unquestionably a technological challenge given the hostile environment where they should operate and the innovative dimension of the offshore aquaculture clusters. However, the contemporary feeding demands of the international population that undoubtedly shall be intensified in the near future given its radical increase, make the implementation of relevant projects an unavoidable process. In that context, indeed, the future of aquaculture relies offshore in deeper water fields. The present project shall constitute a valuable contribution toward this task, given that aside from the traditional lab testing for the adequacy of modern materials for fish cage nets, will go a step further proposing the overall investigation of the their appropriateness in realistic conditions. To this end, the research team will design a complete offshore aquaculture system, together with its mooring system, in installation sites that have been already selected. In addition, a unique experimental campaign shall be performed using proper similitude factors of the expected realistic conditions. The main goal of the project is to develop a complete pilot study for the technological guidance of relevant projects of offshore aquacultures which are the future in fish breeding.

Hybrid thermal spray coatings with self-lubricant properties for wear protection of Internal Combustion Engine piston rings (HYSELFDROPS)
HYSELFDROPS is a 36 months national project starting in summer 2020 and has a budget of about 600.000€.
The proposal HYSELFDROPS is targeting to the development of innovative techniques towards the deposition of hybrid self-lubricating coatings using thermal spray techniques. The proposed innovation lies in the combined self lubricating & anti-wear thermally sprayed coatings that will be developed. This will be realized with the presence within the coating mass of solid (nanomaterials) and/or liquid lubricants (oils microencapsulated in polymers). The proposed hybrid coatings are expected to contribute to significant energy loss reduction of diesel engines due to wear and abrasion for marine applications which contributes in the fuel consumption reduction as well as in the operating and maintenance costs. These coatings present the additional advantage of avoiding toxic chemical substances release to the environment unlike liquid lubricants. Scale up activities in terms of feedstock materials production as well as thermally sprayed real parts (piston rings) for field testing will be performed. The coated piston rings will be implemented in a three cylinder Yanmar 3YM30 diesel engine producing 21.3 kW maximum power at 3200 rpm for marine applications.

developing, demonstrating and validating 13 specific maritime products to prepare for commercial market uptake immediately after the project.
-
conducting a comprehensive assessment of technical properties, life cycle cost and environmental performance of the demonstrator cases as a basis for approval of the specific solutions, but also with the aim to re-use test results, material data and experiences for future similar applications and make this ‘knowledge base’ accessible to a wider range of maritime end-users
-
setting up a Materials Innovation Platform for information exchange and cooperation which is open to other projects.
The RAMSSES consortium comprises of 36 participants from 12 European countries, dominated by industrial partners.
SHIPLYS: Ship life cycle software solutions
European Programme under FP7 (7th Framework Programme) (2016-2019)
Principal Investigator (for Greece): Prof. N. Tsouvalis.
About this project:
SHIPLYS was a three-year project starting in September 2016 and had a budget of about 6.2 million Euros.
The project was in response to needs of SME naval architects, shipbuilders and ship-owners, who in order to survive in the world market required to:
-
improve their capability to reduce the time and costs of design and production
-
develop the ability to reliably produce better ship concepts through virtual prototyping
-
meet the increasing requirements for LCCA (Life Cycle Cost Analysis), environmental assessments, risk assessments and end-of-life considerations as differentiators
The SHIPLYS consortium comprised of 12 participants from 7 countries who brought together a mix of stakeholder organisations and corresponding expertise. The participants included shipyards, a classification society, research institutes and industrial organisations that developed and provided technologies used in structural design and production.
MOSAIC: Materials On-board (steel - composites)
European Programme under FP7 (7th Framework Programme) (2012-2015)
Topic: "MOSAIC: Materials On-board: Steel Advancements and Integrated Composites"
Principal Investigator (for Greece): Associate Prof. N. Tsouvalis
About this project:
The aim of this project was to investigate two novel ideas concerning ship structures. First, the introduction of High Strength Low Alloyed Steels (HSLA) in specific structural details and second the replacement of specific structural parts of the ship with composite materials.
HSLA steels with high toughness properties, in specific areas of the ship structure, reduce the risk of cracks developing in stress concentration areas while composite materials can replace parts of the steel structure, such as superstructures, transverse bulkheads, partial decks and other non-critical parts thereby reducing weight and corrosion effects.
The final outcome of the project was the development of relevant guidelines for the design and application of these two new concepts in shipbuilding.
FOUL-X-SPEL: Environmentally Friendly Antifouling Technology
European Programme under FP7 (7th Framework Programme) (2011-2014)
Subject: "FOUL-X-SPEL: Environmentally Friendly Antifouling Technology to Optimise the Energy Efficiency of Ships"
Principal Investigator (for Greece): Prof. D. Pantelis
About this project:
The main objective of this project was the study and development of an environmentally friendly surface protection. The basic idea was to modify the common pot, providing a new antifouling coating with covalently attaching bioactive molecules that can provide biocidal activity, in order to avoid leaching and to promote a long and effective surface protection. This required an introduction of ingredients through a molecular bridge and study of the active concentration of bound active compounds. In this way, the new technology of surface coatings have minimized the surface roughness and improved the hydrodynamic properties of the hull.

Co-Patch - Composite Patch Repair for Marine and Civil Applications
Program funded by the European Commission (7th Framework Programme - FP7) (2010-2012)
Topic: "Composite Patch Repair for Marine and Civil Engineering Infrastructure Applications (Co-Patch)"
Principal Investigator (for Greece): Associate Prof. N. Tsouvalis
Partner: Prof. V. Papazoglou
About this project:
In January 2010 a consortium of 15 organisations from eight European countries have kick started a European (FP7) funded project on Composite Patch Repair for Marine and Civil Engineering Infrastructure Applications - Co-Patch.
Co-Patch is a novel and potentially effective repair and/or reinforcement method for large steel structures. Two basic structural types will be dealt with, namely marine structures (mainly steel ships) and iron/steel civil engineering structures (e.g. bridges, transmission towers, etc.). It is hoped that the use of patches will significantly reduce the maintenance costs, and in the case of metallic bridges, prolong their design life and help address the consequences of increasing live loads. The proposed technology creates a new market and gives the partners the capability of providing high technology and high added value services worldwide.
Main objectives are to demonstrate to all stakeholders that composite patch repairs or reinforcements can be environmentally stable and therefore, that they can be used as permanent repair measures on steel marine structures and steel civil engineering infrastructure applications.
SuSy - Surfacing System for Ship Recovery
Program sponsored by the European Commission (7th Framework Programme - FP7) (2010-2012)
Topic: "SuSy - Surfacing System for Ship Recovery"
Principal Investigator (for Greece): Prof. V. Papazoglou
About this project:
The propagation of spillages is one of the biggest environmental problems after a ship disaster. Instead of cleaning the dirty areas the SUSY system will avoid the spillages by stabilizing vessels immediately after an accident. Additionally the same technology should be used to lift sunken vessels by spending less effort than today.
The main idea of the proposed project SuSy is to develop well known submarine rescue technology into systems to be used for merchant ships in emergency situation. The systems for submarines are based on satellite booster technology with liquid or solid fuel to blow water out of the ballast tanks in very short time to provide additional buoyancy to stop e.g. an uncontrolled diving process. This technology provides means to generate from a device of 0,5m^3 500 m^3 within 15 seconds under atmospheric pressure.
The combination of this technology with air pressure systems and balloon technology to create a multi purpose modular system for ship rescue purposes is the target of the SuSY project.
