This week NAMIC’s 5th additive
manufacturing summit will address the use of industrial 3D
printing for the maritime and energy sectors.
Joining the event is DNV GL, an
accredited registrar and classification society headquartered
near Oslo, Norway.
DNV GL provides services for 13,175 vessels and mobile
offshore units (MOUs) giving the enterprise a global market
share of 21%. In addition, technical consultancy services are
provided to sectors including renewable energy and the oil
& gas industry. DNV GL’s technical standards inform the
design and installation of 65% of the world’s offshore
As previously reported, DNV GL recently established
Global Additive Manufacturing Centre of
Excellence. The CoE will conduct work looking
at the technical standards and guidelines for qualifying and
certifying AM equipment, processes, products, materials and
personnel. With this project DNV GL intends to increase
adoption of additive manufacturing in the oil & gas
and offshore & marine sectors.
I caught up with Sastry Kandukuri, Global AM Lead at DNV
GL AM Technology Centre of Excellence (AM CoE), and Brice le
Gallo, Regional Manager and director of AM CoE, to learn

3D Printing Industry: How is DNV GL currently working with
industrial 3D printing?
Sastry Kandukuri/Brice le Gallo: With our long
track record in R&D and strong position in developing
industry technical standards, DNV GL aims to enable the
adoption of this new technology in the O&M sector by
providing the industry with technical standards and guidelines
for qualifying and certifying AM equipment, processes,
products, materials and personnel.
The newly established
DNV GL Global Additive Manufacturing Centre of
Excellence is intended to be an incubator and
testbed for 3D printing technology, as well as serving as DNV
GL’s global competence and service delivery centre for
assurance and advisory services. We will make use of our
materials integrity testing and functional testing facilities
available in our lab facilities for endorsing /certifying AM
technology of our clients.

Manager and director of DNV GL’s AM CoE
3D Printing Industry: What applications of 3D printing at
DNV GL do you see becoming possible in the next 5 years?
SK/BLG: DNV GL is a global quality assurance and
risk management company. As a classification society and
technical advisor, we bring a broader view to complex business
and technology risks in global and local markets. Providing a
neutral ground for industry cooperation, we create and share
knowledge with our customers, setting standards for technology
development and implementation. From project initiation to
decommissioning, our independent experts enable companies to
make the right choices.
DNV GL believes that additive manufacturing together with
digitalization as another potential game changer in the M&O
industry. Not only could AM result in new designs for more
efficient components, it could also allow spare parts to be
produced locally around the world. The 3D printing technology
could allow organizations to access an archive of digital
designs for immediate on-site printing rather than maintaining
physical inventories of spare parts and/or waiting for them to
be made and transported to a platform or vessel.
This would equate to less lead time, less cost, less
logistics, and less need to keep stocks of spare parts This
would shorten the time required for repairs and contribute to
more efficient ship operations. AM could also be used for
maintenance and repair, simply adding layers of material to
worn components, thus negating the need to replace them.
3D Printing Industry: What are some of the challenges of
using 3D printing in the Maritime sector, how do you see these
SK/BLG: Some of the challenges to overcome before
3D printing is made possible
initial capital and consumable costs
of cost effective qualification and certification
Unclear IP, legal and regulatory issues
Global traceability challenges with make-on-demand
protection, counterfeiting & product sabotage
Inadequate statistical material property data
Despite considerable research efforts that have been
devoted to understand material integrity issues there are still
many questions that need to be addressed before additive
manufacturing can be utilized in a regular production mode for
critical, load bearing applications. A solution to this problem
will only be found through joint industry efforts to examine
the relationships between the powder-process-properties
performance, and explore the design and manufacture of a
complex, integrated systems for structural applications.
3D Printing Industry: How would you characterise the
importance of 3D printing for DNV GL?
SK/BLG: As digitalization is upon us all it’s no
surprise that 3D printing is also top of the agenda for DNV GL.
Ultimately, this is a group-wide initiative in alternative
manufacturing. DNV GL will use our global network of experts
with deep domain experience, and our laboratories and test
sites to address applications in all business areas of
relevance to us and our customers. It is an amazing opportunity
to impact on the future and to be involved in the future
management of a young talent pool that embraces new disruptive
