Will do ocean repairs of underwater assets with 3D printing technology by 2024

Since 2021, Kongsberg Ferrotech has worked in a joint industry project with the partners Equinor, Gassco and SINTEF to develop and test advanced 3D printing technologies for in situ, metal to metal, repairs of underwater assets. The project achievements have been recognized in the market and Shell is now joining the team.

The partners of the joint industry project are of the opinion that the new methods, in development, represents a game changing way of conducting subsea repairs. Additive manufacturing for lifetime extension of subsea assets, is expected to have great financial and environmental benefits for installed as well as future subsea assets. 3D printing meets the main criteria for sustainability – reduce, reuse, and recycle.

Integrated in robots

The project has identified several applications such as repair of cracks, dents, and replacement of lost materials where the technology will be very beneficial compared to traditional methods. The project has reached important milestones on the way and is currently in the process of qualifying the 3D printing technology for cracks and dents.

Shell onboard

– We’re happy to be part of an exciting development. When we discovered this joint industry project, we realized that the repair methods have many applications within Shell’s global operations. The technology is of great interest to Shell and fits nicely into our portfolio of advanced technology for subsea robotics and 3D printing. We are looking forward to a close collaboration with our industry partners, says Angeline Goh, 3D Printing Technology Manager at Shell.

3D printing technology, will be integrated in Kongsberg Ferrotech’s Inspection, Repair and Maintenance (IMR) robots. In the repair process, a dry environment is created to offer documented high-quality repairs without disrupting ongoing operations.

– We’re excited to welcome Shell to the team and consider their decision as an important recognition of the potential represented by our technology. With another global partner onboard, we’re able to adapt our technology towards a large global market. Together with our partners we’re now preparing for the world’s first test of 3D printing repairs in demanding ocean spaces, says Torgeir Bræin, CTO at Kongsberg Ferrotech.

Recognized in the global market

The original partners are pleased to see that this leading-edge initiative is being recognized in the global subsea market, confirmed by Shell joining the team. Shell’s participation will strengthen the team considerably with more resources, expertise, applications, and market.

The robotized 3D printing project contributes to the energy transition by providing extended lifetime of existing and future underwater assets. The joint industry collaboration is supported by the Research Council of Norway.
