DNV GL, a classification society headquartered in Oslo, Norway, has awarded thyssenkrupp AG, Essen, Germany, the first Additive Manufacturing Approval of Manufacturer certificate.

The society states that the certificate makes thyssenkrupp the world’s first producer of additively manufactured parts for maritime applications to obtain manufacturer approval from DNV GL. Certification was reportedly important for thyssenkrupp Marine Systems as the company reports that it is working with international customers on the integration of AM parts on ships and submarines.

According to DNV GL, the approval covers the Additive Manufacturing and processing of austenitic stainless steel parts. Certification was also awarded for the acceptance process in accordance with EN 10204 and the associated product information, particularly the chemical and physical material characteristics. 

“Additive Manufacturing will have a significant impact on the future maritime value chain,” stated, Geir Dugstad, Director of Ship Classification & Technical Director of DNV GL – Maritime. “Producing components that have the same level of quality as conventionally manufactured parts and fulfil class requirements is key.”

Dugstad added, “At DNV GL, we are very pleased to certify that the thyssenkrupp TechCenter Additive Manufacturing has demonstrated its ability to reliably produce metallic materials using Additive Manufacturing. This is the first time DNV GL has awarded its Approval of Manufacturer certificate, and I would like to congratulate thyssenkrupp on this achievement.”

Dr Luis Alejandro Orellano, Chief Operating Officer, thyssenkrupp Marine Systems, commented, “We are delighted that with thyssenkrupp TechCenter Additive Manufacturing we now have a certified partner who can supply thyssenkrupp Marine Systems with additively manufactured parts that meet both our own and our customers’ high expectations. Together we are putting innovative solutions into our submarines and ships, setting new standards for the navy of the future.”

“A team effort was particularly important here, as the certification required us to rethink traditional methods for quality evaluation and certification,” explained Eva Junghans, Senior Principal Engineer, Materials & Welding at DNV GL – Maritime. “I would like to thank everybody involved for their support and collaboration.”
