DEEP Manufacturing Limited (DML) has just secured DNV approval in principle (AiP) for its use of wire arc additive manufacturing in the production of steel for pressure vessels for human occupancy. This isn’t just a stamp of approval; it’s a game-changer for the maritime and offshore industries. With 20 Wire Arc systems at its Advanced Manufacturing Centre of Excellence in Avonmouth, UK, DML is sitting pretty with one of the largest concentrations of Wire Arc Additive Manufacturing (WAAM) systems globally. This technology isn’t your average 3D printing; it’s a powerhouse that enables the manufacture of large-scale metal components with complex geometries. Unlike powder-based additive manufacturing, WAAM uses an electric arc to melt wire feedstock, resulting in a higher level of material quality.
The benefits of WAAM are no secret. It’s faster than traditional manufacturing techniques like forging, and it can handle a higher degree of design complexity. Initially, these advantages were spotted in the automotive, aeronautical, and military sectors. Now, WAAM is making waves in the subsea supply chain, particularly for pressure vessel manufacturing. Each of DML’s individual robotic systems can produce metallic parts up to three meters in diameter, while the six-arm synchronized configuration supports the production of parts with volumes up to 6.1 meters in diameter and 3.2 meters in height.
DML’s journey with WAAM began as a solution to the underwater pressure vessel manufacturing requirements of DEEP, the ocean technology and exploration company. Now, DML is ready to offer its rapid production timelines and expertise in large-format metal additive manufacturing to projects in the offshore, maritime, and energy industries. The company is in the final stages of the audit process to obtain DNV approval to produce pressure vessels for human occupancy.
Peter Richards, Chief Executive Officer of DEEP Manufacturing, doesn’t mince words. “If subsea companies are still relying on traditional forge and casting methods, they risk falling behind,” he warns. “There is a need for a mindset shift toward innovation and proactive measures to enhance industry-wide resilience. As we move forward, we want to support our customers to embrace innovation and build more adaptable, resilient operations. This is a tipping point for our industry, and it is time to fully leverage the benefits that additive manufacturing offers.”
This news isn’t just about DML; it’s about the future of the maritime and offshore industries. It’s a call to action for companies to innovate or risk being left behind. The approval of WAAM for pressure vessels for human occupancy opens up a world of possibilities. It could lead to more efficient, safer, and more adaptable operations. It could revolutionize the way we think about manufacturing in the maritime and offshore sectors. The question is, who will rise to the challenge and lead the charge?
