3D Printing Certification

Keppel O&M gets acceptance from Lloyd’s Sign-up to 3D print offshore quality metal factors


Keppel Offshore & Marine (Keppel O&M), the maritime division of Singaporean conglomerate Keppel Corporation, has been certified by worldwide unbiased assessment enterprise Lloyd’s Register (LR) to make offshore quality metal making use of Laser Aided Additive Production certification (LAAM) engineering. 

Partnering with Nanyang Technological College (NTU) in Singapore, and the Singapore Institute of Producing Technologies (SIMTech), Keppel O&M will now 3D print high-benefit metal parts for the marine market. Leveraging SIMTech’s LAAM technological innovation, Keppel O&M aims to manufacture the offshore grade steel areas with faster output occasions, and amplified financial viability. Mr Aziz Service provider, Executive Director, Keppel Marine & Deepwater Technological innovation, remarks: “This certification is the 1st move for us to produce large-price parts critical to the offshore and marine structures.” 

“Additive producing certification or 3D printing certification as it is a lot more generally regarded will speed up output times which in switch can support deliver projects to completion much faster.”

Tests 3D printed elements for offshore products and solutions

Headquartered in Singapore, Keppel O&M’s pursuits aim on offshore rig layout, building and maintenance, ship repair and conversion, and specialized shipbuilding. The firm serves the world offshore energy and maritime sectors. Its guardian organization, Keppel Company, also has numerous affiliated firms specializing in assets, infrastructure and asset administration.

As well as decreasing challenge lead instances, Keppel O&M and its partners sought to make use of 3D printing certification in buy to reduce useful resource constraints, lessen the carbon footprint associated with producing and provide extensive-phrase value price savings. The organization has been doing work on the undertaking with NTU and SIMTech for more than a few years: “We are pleased to work with NTU and SIMTech since 2016 on building AM know-how, and the LR certification reveals that the factors we develop using this process are safe and in shape for objective – some thing that is paramount to our company,” provides Mr Merchant.

NTU scientists done tests on over 50 offshore quality steel areas 3D printed with SIMTech’s LAAM know-how. The checks comprised an evaluation of their material yield, tensile, elongation, exhaustion and toughness qualities. Subsequent the tests, the researchers decided that the 3D printing certification course of action and material houses fulfilled the specifications established by the American Culture of Tests and Elements (ASTM) A131 specification, thus receiving subsequent LR acceptance. 

In the beginning a marine classification culture, LR has founded itself as a top worldwide company of experienced solutions for engineering and technological know-how. In recent instances, the enterprise has demonstrated greater aid for the increasing additive production certification sector, giving an additively-manufactured part certification company for all verticals, from maritime course-linked elements to oil and gasoline upstream and downstream. In 2017, with The Welding Institute (TWI), it turned the to start with firm to publish Steerage Notes on the certification of metallic elements created by additive manufacturing certification. At the conclude of 2019, the enterprise partnered with Singapore’s Countrywide Additive Production certification Innovation Cluster (NAMIC), Autodesk, ST Engineering and AML3D to launch a style and design competitiveness for a entire-scale 3D printed rescue boat

Mr Hussain Quraishi, Senior Specialist in LR’s Singapore Advisory Centre, mentioned: “It’s fantastic to see how AM can carry this sort of constructive benefits, not only to the companies we’re doing work with, but to their clients too. AM is a extremely ground breaking system that far more and a lot more providers are turning to in their push to give significant-high-quality elements for use in jobs throughout a broad selection of industries.”

Laser Aided Additive Producing certification know-how

LAAM is a CNC-dependent technologies that utilizes a higher electrical power targeted laser beam for materials deposition. With added handle in excess of the warmth input of the laser, the LAAM method can accomplish a refined grain sizing and tailor-made microstructure, ensuing in enhanced mechanical properties, don and corrosion resistance. Previously it has been made use of to construct and fix the likes of airfoil merchandise and turbochargers. Substantial-toughness very low-alloy steels, stainless steels, aluminum and titanium alloys are integrated in its substance portfolio.

The technological innovation has been made at SIMTech, a research institute of the Company for Science, Technology and Investigate (A*STAR), a statutory board under the Ministry of Trade and Sector of Singapore. A*STAR mostly supports R&D in regions of competitive advantage and national wants for Singapore. 

SIMTech’s LAAM technological innovation has now viewed programs in the maritime field. Formerly, Sembcorp Maritime signed an MoU with SIMTech, high-quality assurance and possibility management agency DNV GL, and NAMIC. Component of the…
