DNV VERIFICATION CERTIFICATE FOR KEPPEL’S 3D PRINTED FITTING

DNV VERIFICATION CERTIFICATE FOR KEPPEL’S 3D PRINTED FITTING

Tuesday, September 14, 2021 

Keppel Technology & Innovation (KTI) of Singapore has received a verification certificate for a 3D printed deck mounted type Panama Chock (SWL 150t), intended for non-class maritime applications, from DNV.

Panama Chocks are used for towing and mooring, traditionally manufactured by casting, and are welded to a ship as a supporting hull structure. This component was manufactured by KTI’s partner AML3D using the patented Wire Additive Manufacturing (WAM) process which uses medium strength structural steel grade ER70S-6 wire feedstock. The DNV verification follows extensive research, production and testing by KTI with end users Keppel  O&M and technology partner AML3D and confirms that the component has met all the primary test requirements in KTI’s project material specification with.

Francois van Raemdonck, KTI MD, said: “KTI has been working on this project with Keppel O&M, DNV and AML3D since 2019, and we are proud to achieve this endorsement. Keppel is transforming the way it harnesses technology and KTI is supporting this by collaborating with Keppel business units to innovate and create value. This is in line with Keppel’s Vision 2030, which includes leveraging advanced technologies to drive growth.”

The 1,450 kg Panama Chock was designed and produced to meet international standards and KTI’s project specific material specification. Material yield strength was twice that of the original cast material and was produced with acceptable internal soundness that was confirmed by various non-destructive testing and evaluation methods. The part was then proof load tested to 20% higher load than its design working load. Following the successful load test, non-destructive and destructive testing, the results were reviewed by all parties before the final verification statement was issued.

“It’s pleasing to see further advances within the offshore and marine industry with this development for the world’s largest 3D printed shipboard fitting. Creating trust is critical for the acceptance of 3D printed parts and DNV’s certificate plays an important role in ensuring that this is the case” said Brice Le Gallo, DNV Regional Director, Asia Pacific Energy Systems.
