Keppel Offshore & Marine receives Lloyd's Register certification to 3D print offshore grade steel parts
Keppel Offshore & Marine, Lloyd's Register | January 14, 2020
Keppel Offshore & Marine has received Lloyd’s Register LR Certification to additively manufacture offshore grade steel with a 3D printing technology from Singapore Institute of Manufacturing Technology SIMTech. The certification was granted after assessing Keppel O&M’s production processes, from design to post-processing and testing. Partnering with Nanyang Technological University, Singapore NTU Singapore and SIMTech’s Agency for Science, Technology and Research A*STAR, the company will now begin to 3D print high-value steel parts for the marine industry with the latter’s Laser Aided Additive Manufacturing LAAM process. Keppel O&M has been working with NTU Singapore and SIMTech for nearly four years to refine the additive manufacturing of steel components. NTU researchers have carried out rigorous testing on over 50 specimens of 3D printed offshore grade steel, assessing their material yield, tensile, elongation, fatigue and toughness properties against ASTM requirements.
