Knowledge basis for repair contingency of pipelines - Final report

Abstract

The RCN competence project ROP was initiated in January 2014, with the main objective to establish basic knowledge on subsea hyperbaric repair welding and degradation of clad and lined pipes, as well as C-Mn steel. The project is motivated by the need for improving the contingency situation and increase the research effort related to clad pipe and CMn pipeline repair in the Norwegian Continental shelf. The research partners have been SINTEF, IFE and NTNU, the industry partners are Equinor, Gassco, Technip FMC, EFD Induction and POSCO. This report summarizes the results from all work packages, a PhD thesis that was finalized in 2018 and post doc work finalized in February 2020. The work packages are: WP1 Structural Integrity, WP 2 Material and process modelling, WP3 Technical solutions and WP4 Demonstrators. An overview of the publications produced in the project is also given.
