Subsea manufacturing, built on proven WAAM capability
DEEP Manufacturing was established to solve the challenges of producing large, pressure-rated subsea components. Originating from the need to manufacture certified pressure vessels for human occupancy, our WAAM capability is now applied across subsea systems, delivering high-integrity structures faster, with reduced lead times and greater design flexibility than traditional methods.
The challenge of manufacturing large subsea components
anufacturing large subsea components has traditionally relied on casting, forging and rolled plate processes that can limit speed, flexibility and efficiency. Long lead times, material waste and complex tooling can slow project delivery, while design constraints restrict optimisation of pressure-rated structures.
As subsea systems evolve, there is a growing need for more adaptable and efficient manufacturing approaches.
Advantages of WAAM for subsea manufacturing
Wire Arc Additive Manufacturing (WAAM) enables faster, more flexible production of large subsea components, supporting performance, efficiency and supply chain resilience.
- Faster production with reduced need for complex tooling or moulds
- Greater design freedom for pressure-rated structures
- Lower material waste for complex geometries through near-net-shape manufacturing
- Scalable for large-format subsea components
- Supports localised, responsive supply chains
DEEP Manufacturing’s WAAM capability
DEEP Manufacturing delivers large-scale WAAM for high-integrity subsea components, supported by DNV approval of manufacture (AoM) for pressure vessels for human occupancy (PVHOs) – a world first.
Originating in subsea pressure vessel production, we integrate ISO 9001-certified design capability with additive manufacturing, machining, inspection and testing to provide a complete, end-to-end solution, enabling delivery of turnkey PVHOs and certified components with reduced lead times and greater design flexibility.
