Launched in January 2025, following a period of extensive research and development, DEEP Manufacturing has harnessed technology to drive speed, scale, and quality to improve commercial resilience and support growth in the supply chain.
The UK-headquartered company has developed groundbreaking manufacturing techniques that bolster supply chain resilience. With 20 Wire Arc systems at its Advanced Manufacturing Centre of Excellence in Avonmouth, UK, DEEP Manufacturing operates one of the largest concentrations of Wire Arc Additive Manufacturing (WAAM) systems globally.
Each individual robotic system can produce metallic parts up to three meters in diameter, while the revolutionary six-arm synchronized configuration supports the production of parts with volumes up to 6.1 meters in diameter and 3.2 meters in height.
Initially developed as a solution to the underwater pressure vessel manufacturing requirements of DEEP, the ocean technology and exploration company, the business has the capability and capacity 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 now in the final stages of the audit process to obtain DNV approval to produce pressure vessels for human occupancy.
Peter Richards, Chief Executive Officer, DEEP Manufacturing, said: “Achieving DNV approval in principle for our manufacturing processes demonstrates our commitment to high standards and uncompromising quality. Partnering with DEEP Manufacturing provides customers with the rapid delivery of long-term, cost-effective, subsea manufacturing solutions driven by superior quality.
“We are the only company in Europe with this AiP, and we are already in the process of working towards final DNV approval for the production of steel pressure vessels. Our combined subsea engineering resources, knowledge, and experience across DEEP means we can deliver manufacturing projects at an unprecedented scale, faster, and at lower life of project costs compared to traditional manufacturing processes.
“Using DEEP Manufacturing’s additive manufacturing process allows companies to stay ahead of the game in their subsea projects. Additive manufacturing is the fast, safe solution to manufacturing large-scale, complex metal parts.”
Peter continued: “If subsea companies are still relying on traditional forge and casting methods, they risk falling behind. 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 in embracing innovation and building 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.”
Dr. Eva Junghans, Senior Principal Engineer and Practice Lead for Materials & Welding, Additive Manufacturing at DNV Maritime, said: “It is a great pleasure to award DML this AiP and is another step forward in utilizing additive manufacturing at the cutting edge of the maritime industry. This AiP shows that DML has demonstrated the feasibility of AM in the manufacture of large-scale components that can fulfill maritime quality standards—further expanding the potential uses of AM for our industry.”
Thorsten Lohmann, Head of the Materials & Welding Section at DNV Maritime, said: “At DNV, we have been working with manufacturers on safely realizing the unique capabilities of additive manufacturing for many years with our class framework, rules, and guidelines. Going forward, we will continue to help our customers show that AM-produced parts can be accepted under the class regime, driving progress and acceptance of this exciting technology.”
