DNV GL leading program to advance 3-D printing for marine parts

The goal is to help the shipping industry cut costs and downtimes

The following is text of a news release from DNV GL:

(SINGAPORE) — DNV GL has been appointed as the lead researcher of the first phase of a new Singapore-based program to study the feasibility of additive manufacturing (AM), or 3-D printing, in the maritime industry. In a joint industry program (JIP) initiated by the Maritime and Port Authority of Singapore (MPA) DNV GL will team up with 10 member companies of the Singapore Ship Association (SSA) to examine how spare parts produced by 3-D printers can help the capital-intensive industry to cut costs and downtimes.

The goal of the JIP is to establish a list of commonly-ordered parts that are highly feasible for 3D printing with or without certification respectively not feasible for 3D printing. The findings aim to encourage more maritime players to adopt AM to optimize their spare parts supply, and overall to strengthen Singapore’s value proposition as a one-stop shop with port services supporting a diverse ecosystem of shipping lines and maritime companies.

To date, the challenges of marine parts inventory include not only inventory costs, low utilization rates and parts obsolescence, but also complex supply chains and accompanying logistics costs. AM technology has the potential to revolutionize the way marine spare parts are designed, manufactured, and distributed to end users. In addition, on-site manufacturing for maintenance becomes an important application of AM.

“Additive manufacturing holds great opportunities for the maritime industry,” said Cristina Saenz de Santa Maria, regional manager Southeast Asia, Pacific and India, DNV GL-Maritime. “As the world’s leading classification society our aim is to explore this technology in a way that customers can have the same confidence in AM products as they have in any other approved by class.”

The SSA underlined the disruptive potential of AM, which so far has seen only a moderate uptake in the industry. “This technology can help not only to reduce costs of producing spare parts for vessels, but also to radically reinvent the production and logistics including using completely new and more suitable materials,” said Steen Brodsgaard Lund, chairman of the SSA Technical Committee. Elements potentially replaced by modern materials include brass components, he explained.

“We believe that the best way forward in the development of AM is collaboration across the ecosystem,” said Kenneth Lim, director, research and technology and industry development transformation at MPA. “As Singapore seeks to be the global maritime hub for connectivity, innovation and talent, we are excited to see that multiple stakeholders are together exploring the potential of how additive manufacturing can be applied in the maritime industry to create greater value.”

AM as an enabling technology for innovation and productivity improvements in the maritime sector is one part of Singapore's Sea Transport Industry Transformation Map, to grow the maritime sector's value-add by $4.5 billion and create more than 5,000 highly qualified jobs by 2025. In 2015 Singapore also saw the start-up of a National Additive Manufacturing Innovation Cluster (NAMIC) to speed up industrial adoption of AM.

In 2018, DNV GL also released the first approval of manufacturer (AoM) scheme for additive manufacturing producers wishing to supply products that comply with the DNV GL rules and standards, following the publication of the first guideline for the use of AM in the maritime and oil and gas industries in 2017.
