QUALIFY is a research and innovation project with a budget of €3.8 million, of which €2.3 million are funded by the Interreg 2 Seas Programme 2014-2020, co-funded by the European Regional Development Fund.


  1. Tests to assess the sensitivity to the environment of the adhesive material properties and the structural performance of the joint at different scales

  2. Tailored equipment to evaluate the performance of the hybrid joint under combined loading and environmental conditions

3.  Accelerated tests type 2. Testing of corrosion assisted fatigue to evaluate components in a representative 

     environment and  at different scales

4.  Monitoring and inspection protocol

5.  Structural health and condition monitoring tests

6.  Guidelines for the qualification of adhesively bonded hybrid structures in  primary structures for marine applications


The QUALIFY project is organzied in five workpackages: three technical workpackages (WP1, WP2, WP3) and two non-technical: WP4 (management), WP5 (Dissemination). 

WP1 Long term performance of hybrid structures 

The long term mechanical performance of the adhesively bonded joint will be evaluated, under representative operational and environmental conditions.

WP2 Inspection and monitoring
Inspection and monitoring

A structural health management methodology is developed for in-situ monitoring of hybrid adhesive joints.

WP3 Guidelines for the qualification of hybrid bonds

Led by the class societies, project guidelines for adhesively bonded hybrid joints (steel/composite) of marine and offshore structures are developed.
