Subsea Additive Manufacturing for Life Time Extension (SAMLE)

Offentlig prosjektsammendrag

The idea of the SAMLE (Subsea Additive Manufacturing for Lifetime Extension) project is to introduce the Additive Manufacturing method for permanent repair of subsea components to extend their lifetime. The core of the SAM technology is the unique habitat and control technology of Kongsberg Ferrotech (KF) combined with an innovative hyperbaric wire arc additive manufacturing (WAAM) process, which will enable permanent repair of subsea components. The main R&D challenge is to establish the process-property-performance relationship of the SAM process to achieve predictive and controlled repair. The SAM process shall, for most cases, be applicable for hot repair i.e. repair of pipelines with active flow etc. The development method is based upon extensive simulations and verification of selected methods. The verified simulation models will be part of a digital twin. The digital twin becomes a key element in repair planning, quality control and documentation.
