The maritime sector is more and more adopting Additive Manufacturing (AM) to enhance effectivity and sustainability in shipbuilding and offshore operations. In contrast to conventional strategies equivalent to casting, forging, and welding, AM permits on-demand manufacturing, design flexibility, and decreased materials waste.
IACS Advice 186: A Standardized Framework for AM Adoption
The Worldwide Affiliation of Classification Societies (IACS) has launched Rec. 186: Additively Manufactured Metallic Components for Marine and Offshore Purposes, which supplies pointers for qualification, approval, and certification of AM metallic elements. This framework aligns with ISO/ASTM 52900 and AWS D20.1 requirements, making certain reliability and security for marine purposes.
Key Areas Coated in Rec. 186
AM Course of Scope: Covers Powder Mattress Fusion (PBF), Directed Vitality Deposition (DED), and Binder Jetting (BJT) with detailed process-specific parameters.
Criticality Ranges and Testing: Introduces AM Ranges 1-3 for sophistication and licensed objects, permitting testing primarily based on software significance.
Feedstock and Materials Requirements: Defines rigorous qualification processes for AM feedstocks like powder, wire, and binders, incorporating recycling protocols for sustainability.
Half Design and Qualification: Encourages design optimization, topology adjustment, and pre-build simulation for enhanced efficiency in marine environments.
Inspection & Non-Harmful Testing (NDT): Addresses anisotropic properties and defects (porosity, lack of fusion) utilizing CT scans and superior NDT strategies.
Driving Innovation in Shipbuilding and Offshore Engineering
By making certain standardized verification and certification, Rec. 186 helps the secure and efficient adoption of AM know-how in vital marine purposes. IACS continues to collaborate with shipyards, OEMs, and vessel operators to develop AM’s function in safety-critical parts, fostering innovation in shipbuilding and offshore engineering.
Professional Perception
Alexandre Astruc, Chair of IACS’ Professional Group on Supplies & Welding, emphasised:
“Additive manufacturing, or 3D printing, is more and more turning into a invaluable instrument for the marine sector, providing a versatile, speedy and customisable resolution for environments the place the results for security, sustainability or operational uptime can in any other case be vital. Whereas its potential for fast manufacturing is notable, its true energy lies in its skill to supply revolutionary, on-demand options tailor-made to complicated maritime challenges. In creating Rec 186, IACS is looking for to safeguard the advantages supplied by additive manufacturing by making certain it’s underpinned by a standardised framework for verification and certification that offers confidence to all events.”
