Robust new 3D printed parts, installed on the “Polar Works” tanker

China3D printingOn the seventh day of the Chinese New Year, the manufacturing alliances including ABS, Sembcorp Marine and 3D Metalforge have improved3D printingThe parts were installed on the ConocoPhillips polar tanker.
Used by two companies3D printingThe technology created a functional centrifugal pump shaft, a combined brine/air ejector nozzle and a waste water pump coupling for the “Polar Endeavour”. Each new part of the ship not only passed the industry inspection, but also passed the safety inspection.According to China3D printingNet understands that the performance of this product is also superior to many mass-produced alternative products.

“The cooperation with ABS and 3D Metalforge is a continuation of Sembcorp Marine’s ability to continuously innovate and improve production capacity,” said Simon Kuik, director of Sembcorp’s R&D department. “This development enables Sembcorp Marine to further improve our products and provide customized solutions safely and efficiently.”

Sembcorp Marine Mission

In the past few years, ABS and Sembcorp have established3D printingExtensive experience in airworthy parts. In particular, ABS is heavily involved in the supervision of marine AM, and it recently released a set of parameters for manufacturing marine objects, with particular emphasis on process repeatability.
At the same time, Sembcorp is an offshore production expert, which is deployed in MRO operations3D printingIt has been more than four years. The company has close ties with Singapore’s National Additive Manufacturing Innovation Cluster, and the two companies have collaborated to develop a digital twin of the entire ship design.

Elsewhere, Sembcorp promises to use3D printingCreate a large structure for the new ship and carry out whole ship repairs. Recently, the company has also developed a parameter set for new additive parts and seeks novel applications of this technology in the maritime field.
In 2019, Sembcorp was certified by DNV GL, which can3D printingUsed as a means of repairing non-critical parts, such as worn metal sleeves often used in pumps. Now, as part of its latest nautical project, the company has partnered with ABS and 3D Metalforge to create not only novel parts, but also functional improvements that represent the parts they replace.

Polar EndeavorOperated by ConocoPhillips, it is a 20-year-old crude oil tanker, and because it has always undertaken the task of moving heavy objects along the coast of the United States, its functional components must be very safe.Currently, the ship’s spare parts and repairs are produced through traditional casting or forging technology, but now the team led by ABS has been deployed3D printingTo upgrade it.

During the project, the consortium manufactured three distinct components and conducted strict industry standard tests on them. Tried and tested nautical products, these enhancements are now installed on Polar Endeavour ships, ready to respond to sea challenges.
Although Patrick Ryan, senior vice president of global engineering and technology at ABS, said the company is “proud to support the project,” he emphasized the importance of safety in future research and development. Ryan said: “This is a key development in technology that will undoubtedly play an important role in the future of the industry. ABS is committed to ensuring that these types of parts are introduced without compromising safety.”

3D printingIn addition to outperforming traditional maritime components, the version also proved the technology’s potential in reducing delivery time.Given that other maritime agencies such as the Dutch Navy are increasingly providing on-demand3D printingSpare parts, so the project can also serve as a pioneer in improving the availability of parts on commercial ships.


Marine additive manufacturing

3D printingIt has developed rapidly in the field of naval engineering, and many shipyards are experimenting with this technology to produce end-use parts.The Spanish shipbuilder Navantia has even developed a dedicated marine3D printingmachine. Using a custom system they called “S-Discovery”, the engineers were able to make two grilles for the ventilation system of the Monte Udala Suezmax tanker.

Additive manufacturing has also recently been widely involved in naval military applications. For example, in January 2021, the defense contractor Naval 3D Group printed the entire propeller for the French Navy. According to reports, this large component has a span of 2.5 meters and five 200kg blades, and is said to be the largest component in the world.

Similarly, the U.S. Navy Naval Sea Systems Command (NAVSEA) has begun to approve the3D printingThe parts are used for installation on ships. The first approved component is the prototype drainage screen hole (DSO) component, which is designed to drain water from steam lines on aircraft carriers.
