Keppel Offshore & Marine harnessing 3D printing technology for component production

Singapore’s Keppel Offshore & Marine, in partnership with Nanyang Technological University and the Agency for Science, Technology and Research (A*STAR), and Singapore Institute of Manufacturing Technology (SIMTech), has been awarded Lloyd’s Register (LR) Certification for its laser aided additive manufacturing system to produce offshore grade steel.

The certification conforms to the American Society of Testing and Materials (ASTM) A131 requirements following an audit and successful mechanical testing.

“This certification is the first step for us to produce high-value components essential to the offshore and marine structures. Additive manufacturing (AM) or 3D printing as it is more commonly known will speed up production times which in turn can help bring projects to completion much quicker,” said Aziz Merchant, Executive Director, Keppel Marine & Deepwater Technology.

Merchant ship owners to produce spare parts on demand using 3D printing

MERCHANT ships are massive — often spanning a few hundred feet — and have thousands of moving parts.

Given the progress made by cross-border trade and commerce post-globalization, and the recent rise of e-commerce, more than 50,000 ships undertake nearly half-a-million voyages every year.

To avoid catastrophes while at sea, merchant ships need to be serviced often. One of the major costs that merchant ship owners have to account for when it comes to maintenance is the inventory cost of spare parts given the number of spares that must be carried at any given time.

The other challenge to effective maintenance is that ships travel from one port to another during its voyage. If something needs to be repaired when it is not at its home, spares must be sent to the port where it is docked.

6 strategic maritime customers benefit from Wilhelmsen and Ivaldi 3D printing on demand

The Marine Products division of global maritime industry group Wilhelmsen has launched a program to supply 3D printed spare parts on demand to ships and other vessels. Part of an ongoing collaboration with advanced and additive manufacturing service bureau Ivaldi Group, the service is exclusively open to a group of six early-adopters.

Advantages promoted by the program include the elimination of physical inventory, streamlining complex distribution, and a reduction of associated costs. “The savings from reduced cost, time and environmental footprint provided by 3D printing, digital inventory and on-demand localized manufacturing of maritime spare parts is a tremendous opportunity for our valued subscribers to be ahead of their rivals,” comments Hakon Ellekjaer, Head of Venture, 3D Printing at Wilhelmsen, adding:

“WE BELIEVE ON-DEMAND MANUFACTURING TECHNOLOGIES ARE GOING TO COMPLETELY RESHAPE THE MARITIME SUPPLY CHAIN.”

ThyssenKrupp Additive Manufacturing approved for maritime supply

German multinational engineering group Thyssenkrupp has obtained certification for its supply of metal 3D printed products. The company’s Approval of Manufacturer certificate is the first ever to be awarded by leading quality assurance and risk management firm DNV GL. With the accreditation, the recently opened Thyssenkrupp TechCenter Additive Manufacturing is now approved for application in maritime and other industrial sectors.

Testing the potential of additive manufacturing

Additive manufacturing, or 3D printing, has the potential to transform the maritime equipment supply chain. With the adoption of technology enabling printing in metal, vital spare parts and system components can now be printed on demand in locations around the world, including on vessels themselves. The result is dramatically reduced lead times, costs, labour needs, stock requirements and environmental impact (with less logistics and less waste), as well as the complete disruption of traditional business models.

And that’s just the supply side. The impact on manufacturing capability is just as radical. Suddenly the constraints of traditional processes can be broken, with machines bringing previously impossible designs to life through the precise application of layer upon layer of metals. For the frontrunners in maritime manufacturing, such as Wärtsilä Moss AS (a division of Wärtsilä Marine Solutions), it represents a special kind of magic.

Unique potential

“We came up with a new design that could only be realized with AM fabrication,” he explains. “The geometry of the part, the complexity involved in producing it, makes it far too difficult and expensive to manufacture using traditional methods. It can only be brought to life with AM.”

US Navy holds event to promote 3D printing at shipyards

The US Navy has conducted Print Sprint II event in San Diego to encourage the use of 3D printing technology at naval shipyards to support fleets.

Naval Sea Systems Command (NAVSEA) Tactical Innovation Implementation Lab (TIIL) organised the event designed to enable navy maintenance providers to work collaboratively to develop new 3D printing solutions and applications.

Print Sprint II comes after the first print sprint was conducted last year at Naval Undersea Warfare Center (NUWC) Division Keyport to gauge the fleet and shipyards’ abilities to create a random part in a short time through additive manufacturing.

The biggest waves in maritime additive manufacturing

Maritime AM

The maritime industry may not yet be at the same stage as, say, the aerospace or automotive industries in terms of additive manufacturing adoption, but there have been some tangible steps on the parts of shipping companies, ship manufacturers and port authorities to explore and accelerate the use of maritime additive manufacturing applications. On the marine side, as well, additive manufacturing is increasingly being used to produce custom or small batch components for yachts and sailboats.

As with any new technology adoption, the maritime and marine segments are currently experiencing a lot of “firsts” with 3D printing. As part of our AM Focus this month, we’re going to take a look at some of the most exciting and boundary-pushing announcements in the intersecting maritime and AM sectors.

3D printing to produce maritime spare parts and cut out supply chain and logistics costs

Norwegian classification society DNV GL and all round industry group has been appointed as the lead researcher of the first phase of a new Singapore based programme to study the feasibility of additive manufacturing (AM), or 3D 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 ten member companies of the Singapore Ship Association (SSA) to examine how spare parts produced by 3D printers can help the capital-intensive industry to cut costs and downtimes.

Shipping News Feature

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. 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.
