An adhesive-based joining technology for the subsequent attachment of secondary parts to coated steel structures
The subsequent mounting of equipment is an issue during the outfitting of steel structures when, for example, pipe sections, cable traces, sensors or fixings need to be attached onto already coated surfaces. This refers to external as well as to internal surfaces. When applied to coated structures, welding and bolting are associated with a number of drawbacks, namely heat induction, coating damage (including reverse side damage), notch sensitivity, steel deformation, fume, and dust. An alternative to these techniques is the utilization of adhesives for the mounting processes.
The following results are achieved:
- Development of a standardized adhesive-based bracket system.
- Development of an application procedure for marine and offshore applications.
- Certifications issued by the Classification Societies Lloyd’s Register and RINA.
- Applications of the new technology to offshore structures under site conditions.
