Sembcorp Marine: ABS approves 3D printed spare parts after successful tests on board an oil tanker


ABS approves 3D printed spare parts after successful testing on board an oil tanker

ABS, ConocoPhillips Polar Tankers, Sembcorp Marine and 3D Metalforge complete flagship “additive manufacturing” project

Singapore, November 24, 2021: ABS, ConocoPhillips Polar Tankers, Sembcorp Marine Ltd and 3D Metalforge have taken an important and tangible step towards making additive manufacturing (AM) – also known as 3D printing – a reality in the maritime industry thanks to a joint development project. The parts manufactured by AM and installed on an oil tanker by Sembcorp Marine six months ago have been validated in good working order.

This pioneering FA project began in February 2021 with the manufacture and laboratory testing of functional parts manufactured by additives, which were then installed on board the tanker. PolarEffort. After six months of operation, all parts have since been collected and inspected by the ship’s crew, followed by a remote investigation by ABS.

Mr. Patrick Ryan, ABS Senior Vice President, Global Engineering and Technology, said: “We are delighted with the performance of the parts and the success of the project. This is an important step forward for a technology that certainly has an important role to play. in the future of the maritime industry. ABS is committed to ensuring that these types of parts are introduced without compromising safety. ”

Additive manufacturing or 3D printing is the manufacture of parts by adding material layer by layer. This means that products and components can be manufactured locally or potentially aboard vessels and offshore assets, reducing the supply chain and lead times for specialized and complex parts, introducing new efficiencies through to design innovation, reduction of manufacturing time and improvement of parts availability.

Traditional parts used in shipbuilding and repair are made through casting or forging techniques. For this project, the consortium used AM to manufacture three types of parts that meet or may even exceed conventionally manufactured products in terms of quality. ABS has now approved these aftermarket parts manufactured with additives after successful onboard testing on an oil tanker.

The three parts were:

  • Boiler Fuel Feed Pump Gear and Gear Set: The gear set includes a drive gear that rotates the idler gear connected to the pump that creates a suction force to fill the fluid vacuum. The shaft connects the impeller to the motor / motor, which is the power source.

  • Flexible coupling for marine sanitation device pump: The flexible coupling connects a drive shaft to a driven shaft for power transmission. Both shafts include metallic components for two coupling sleeves and non-metallic components for the coupling spider which allow misalignment adjustments.

  • A freshwater generator ejection nozzle that increases fluid velocity to transform high static pressure into velocity pressure.

Mr. Robert Noyer, Engineering Superintendent of ConocoPhillips Polar Tankers, said: “The superior performance of these parts in service is a testament to the rigorous engineering, manufacturing and post-production tests put in place by the team involved. in this enterprise. We look forward to future opportunities to support our vessels with this technology. ”

Sembcorp Marine’s head of research and development, Mr. Simon Kuik, said: “The success of this project bodes well for the adoption of AM in the marine industry. Through AM, Sembcorp Marine is able to customize parts for our customers and reduce material wastage and eliminate supply chain inefficiencies. This increases our value proposition as a provider of innovative one-stop-shop solutions for the offshore, marine and energy industries and affirms our sustainability ethic. ”

Mr. Matthew Waterhouse, Managing Director of 3D Metalforge, added: “We are proud to work as a trusted partner, with companies like ABS, Sembcorp Marine and ConocoPhillips Polar Tankers to deliver greater value through solutions from new and innovative manufacturing; and to help respond to changing component manufacturing, supply chain and sustainability challenges. The inspection and validation of these additively manufactured components reinforces our belief in this technology and its application. This exposure to the capabilities of additive manufacturing will expand its commercial applications and acceptance in the future ”,

ABS has been supporting the industry with the introduction of FA since 2017. In 2021, ABS Guide to additive manufacturing has been published, focusing on two main categories of metal AM processes: powder bed smelting and directed energy deposition. The Guide defines the ABS approval and certification process for FA installations and parts by providing standards for FA design, raw materials, pre-construction, construction and post-construction processes, l inspection and testing. The Guide places a strong emphasis on the quality of the materials and the manufacturing process, both of which are key elements of the ABS process. Download a copy of the Guide here.
