As part of a nationally-funded German research project, a new mounting procedure for maritime and offshore environments using adhesives has been developed and tested in laboratory and field applications. Based on a benchmark study, suitable adhesive materials and surface preparation methods were evaluated. Furthermore, representative loading cases and environmental conditions were determined. Loading scenarios included tensile tests, shear tests, torsion tests, creepage, and fatigue tests. Specimens were tested under unaged conditions and aged conditions, whereby the aging procedures included temperature changes, humidity, and neutral salt spray tests. Six different metals/coating materials were tested as substrates for adhesive application. Metals included construction steel, stainless steel, and aluminum, whereas the coating materials covered epoxy, polyurethane, and polysiloxane. The paper reports the details of testing and the results obtained for the different testing scenarios.
