WAAM as a Key Enabler for Repurposing Ships and Maritime Equipment
Repurposing ships and maritime equipment is becoming increasingly important as operators look to extend asset lifetimes, reduce waste, and adapt vessels to new operational requirements. Wire Arc Additive Manufacturing (WAAM) offers a practical way to modify, repair, and upgrade large metal structures without the need for full replacement or long supply-chain lead times, thanks also to the print-on-demand service offered by us.
Adding Material Directly onto Existing Ship Structures
One of the key strengths of WAAM in maritime applications is its ability to add material directly onto existing components. Using welding wire and robotic deposition, structural elements such as deck supports, brackets, reinforcements, or mounting points can be rebuilt or redesigned directly on existing ship structures. This makes WAAM particularly suitable for converting vessels for new functions, such as retrofitting research equipment, offshore energy systems, or updated propulsion and handling systems.
Remanufacturing and Upgrading Worn or Obsolete Maritime Components
WAAM is also well-suited for the remanufacturing of worn or obsolete maritime components. Items like pump housings, impellers, flanges, and structural nodes can be rebuilt to their original geometry or redesigned for improved performance. Because WAAM uses commonly available welding alloys, material compatibility with existing ship structures is high, which simplifies qualification and certification for marine environments.
Strengthening Supply Chain Resilience with On‑Demand WAAM Production
Another advantage of WAAM is its role in supply chain resilience. For older vessels or specialized maritime equipment, original spare parts may no longer be available. WAAM enables the production of custom or one-off components based on digital models, reducing downtime and avoiding costly redesigns or full component replacement. This approach supports circular economy principles by keeping ships and equipment in service for longer periods.
From Replacement to Upgrade: A New Approach to Maritime Asset Management
Overall, WAAM enables shipowners, operators, and shipyards to move from replacement-focused maintenance to upgrade-driven asset management. By combining design freedom, material efficiency, and on-demand production, WAAM supports more sustainable and flexible repurposing of ships and maritime equipment.
