08 DNV GL
As a safe and low-carbon alternative to traditional energy sources, liqueied natural gas (LNG) has risen rapidly up the agenda of gas operators in recent years. With a number of important LNG mega projects underway in countries such as Australia, innovative technologies and targeted support are necessary if operators are to close the remaining gaps in the supply chain from the borehole to the consumer.
SUPPORTING THE
RISE OF LNG
DNV GL has already played a key role in the development
of new technologies, services, standards and
recommended practices for the LNG sector. We work
in partnership with a number of LNG pioneers and have
supported the safe development and operation of 35%
of the world’s LNG plants.
This has included completing a pioneering project to
conduct a pre-FEED study for one of the world’s irst loating LNG (FLNG) FPSO vessels; classing Kanowit, the irst FLNG to be put into operation; and classing the conversion of an
FLNG carrier to an FLNG unit in Singapore. We also veriied the fabrication and installation of the Wheatstone gas ield mega project in Western Australia.
In partnership with our customers, DNV GL has developed
offshore service speciications for the veriication, certiication and classiication of gas export and receiving terminals (DNV-OSS-309) and the veriication of onshore LNG and gas facilities (DNV-OSS-315). Our industry projects
have also resulted in recommended practices for the
development and operation of LNG bunkering facilities
(DNV-G106), offshore technical guidelines for loating
liqueied gas terminals (OTG) and certiication standards related to the on board use of LNG as fuel (3.325).
Services across the LNG value chainDNV GL’s expertise in the LNG sector extends from
maritime and offshore assets to onshore bunkering and
transportation. Our experience across the complete
lifecycle of LNG production allows us to develop
customer-speciic solutions from risk management to
effective asset operation. Our integrated technical and
commercial design methodology aims to quantify and
mitigate risks from the earliest project stages.
We have more than 60 years of experience in assurance
and advisory services relating to LNG carriers, including
classiication and third-party veriication for FLNG and loating storage and re-gasiication units (FSRUs). FLNG and FSRU projects require expert support if operators are to
ensure that they are constructed on time and to budget, and
that they will operate safely once launched.
DNV GL’s network of specialists provides due diligence
assessments and design support for new LNG vessels,
covering everything from well heads to subsea work,
including topside work, the hull, ofloading and logistics.
Harnessing LNG’s potentialLNG is capable of bringing previously inaccessible gas
reserves to market, but the demand on the developing
technology is high. DNV GL’s experts are experienced in
supporting the growing LNG leet, including performing safety studies on LNG releases from carriers and during
transfer operations.

LOOKING TO THE FUTURE... TODAY
Gas as a transportation fuelLNG (and to a lesser extent CNG) is one of the key potential new fuels for the transport sector, as a replacement for
oil-based fuels such as diesel and oil. Its use could signiicantly increase in future, as a result of tougher emission
regulations for ships, cars, boats, trains and trucks, and the positive price development of gas compared to oil. To assist
customers in this area, DNV GL offers a wide range of technical and inancial risk management services for the
implementation of gas in the transportation sector.
As a result of our collaborative approach to the sector, we have developed and set a number of standards for LNG as a
fuel. This has included developing the ISO LNG bunker standard, designing a recommended practice on LNG bunkering,
and developing a knock method to create an ISO standard to characterise the knock resistance of LNG fuels. In addition,
we have established a competence standard for crew working with LNG as a fuel and undertaken a number of feasibility
studies for LNG projects.
In addition, DNV GL’s experts help pave the way for safe
and eficient end use of LNG. Where it is being
introduced into natural gas pipelines, DNV GL has
assessed possible changes in the performance of
consumer equipment. In the Netherlands, this has led to
regulations allowing the safe use of LNG in the gas market.
Our risk-focused services help operators to assess and
overcome many of the practical challenges involved with
LNG. This includes providing strategies and training for
rapid response should an LNG spill occur, and advising on
health and safety requirements during vessel design
or vessel-to-vessel fuel transfers.

DNV GL works to assist start-up and established shale gas
operators in both developing and developed markets.
We help them to ensure the safe, reliable and sustainable
performance of their assets, and to demonstrate and
institute operational best practices as a means to achieve
public and stakeholder acceptance.
We recognise that if the sector is to overcome public
concerns around shale gas operations, it will need to
provide answers to the safety, health and environmental
risks involved. To do this, it will need to demonstrate that
projects are able to operate safely and responsibly.
Our risk-based approach to project planning,
development and optimisation enables operators to
assess, mitigate and monitor inherent risk in their shale
gas operations. Our robust procedures for qualifying new
technology evaluate new equipment and materials
destined for drilling and hydraulic fracturing operations.
Our independent veriication and technical assurance
services further enable shale operators to demonstrate
that they are able to manage contentious issues in an
accurate, balanced, transparent and traceable way, while
maximising extraction potential.

DELIVERING A
SAFE FUTURE FOR
UNCONVENTIONAL GAS
Unconventional gas has dramatically shaken up the energy sector in recent years. Advanced tools and technologies have enabled operators to access important and vast new sources of gas supply. However, as the industry continues to develop new techniques and technologies to access these important sources of energy, it will also need to overcome environmental concerns, and many geological, technical as well as economic barriers to growth.
In addition, DNV GL’s expertise in the effects of variations
in gas composition for end-use equipment enables
unconventional gas producers to ensure the commercial
value of their gas; for example, by helping to specify the
gas compositions suitable for their ultimate customers,
the end users.
DNV GL also provides a wide range of Synergi™
modelling software to identify, predict and address
operational challenges in hydraulic fracturing.
Setting industry best practice for shale In partnership with our customers, DNV GL has developed
the world’s most comprehensive recommended practice
for managing risk in shale gas developments and
operations (DNV-RP-U301), as well as procedures to
qualify new technology (DNV-RP-A203).
DNV-RP-U301 covers the entire lifecycle of gas
extraction from shale formations. It provides shale gas
stakeholders with a common focus for quality and safety,
helping to align industry practice, and to address public
and environmental concerns.

services that support a more sustainable and secure
future for their gas assets, including:
Gas has an important role to play in developing a sustainable and reliable energy infrastructure. Supported by growing demand for more environmentally-friendly solutions and higher standards of public safety, the industry has begun to focus on the potential of natural gas to provide a safe energy resource with a lower environmental impact.
DNV GL is working with operators across the world to help them to build secure and sustainable gas operations that reduce emissions by driving operating eficiency. This includes services and guidance for integrating alternative renewable energy sources, safely capturing and storing carbon, and complying with national environmental legislation.
Biogas services DNV GL has undertaken a series of projects focused on
the development of novel uses of low-caloriic-value and renewable-energy fuel sources in modern combustion
systems. These have been conducted to support operators
in their goals to explore the utilisation of biogas, syngas,
landill gas and biomass technology. They include the
co-iring of natural gas and bio-derived fuel, and efforts to
maximise the recovery and use of chemical energy
available in biomass and waste. As a result of the projects,
we have developed a series of process designs for the
improved usage of bio-derived fuels (from anaerobic
digestion, pyrolysis and gasiication).
Enabling enhanced performance with carbon management technologiesCarbon management technologies enable the oil and gas
industry to remain competitive in a carbon-constrained
economy, helping to provide carbon solutions. This is
important to uphold future energy supply and the
production of essential hydrocarbon-based materials
while limiting climate change.
DNV GL services span the entire value chain of CO2,
including capture, conditioning, compression, transport
and storage. We build trust for industries, investors and
governing bodies globally from strategic planning through

and CO2 storage (DNV-RP-J202).
Power-to-gas servicesPower-to-gas is a new and innovative technology that
facilitates the integration of renewable power sources and
the decarbonisation of the gas system. DNV GL supports
operators seeking to adopt this new technology by
providing services relating to enterprise risk management
activities (business case studies, gas and power grid
simulations, strategic advisory), innovation support
(demonstration projects), and operational excellence and
veriication activities.
We have experience in qualifying and verifying
power-to-gas technology and system conigurations for investors, utility companies, grid operators and vendors
in order to reduce risk; for example, in relation to process
design errors, technological failure, underestimated
maintenance intensity or operational failures. In addition,
we have undertaken a series of industry projects to
develop and establish best practice in this area. This
includes setting technical engineering guidelines,
developing recommended practices for power-to-gas
projects and ensuring gas quality compliance.
Hydrogen supply servicesMuch of the world’s existing natural gas network has the
ability to accommodate a certain percentage of hydrogen
added to natural gas. By converting energy from renewable
sources, such as biomass and wind/solar electricity, into
hydrogen, operators are able to harness green forms of
natural gas and to increase the implementation of
renewable energy sources. However, the physical and
chemical properties of hydrogen differ from those of
natural gas, and some changes to gas network components
and end-user appliances may be necessary in order to
accept hydrogen/natural gas mixtures.
DNV GL has been involved in a number of projects, including
the EC-funded project NATURALHY, to investigate whether
existing natural gas infrastructure and end-user appliances
are able to accept hydrogen in terms of safety, system
integrity and end user effects. Our research into this area
has enabled us to build up a number of services to support
pipeline operators as they prepare to inject hydrogen and
hydrogen containing gasses into their network grids.
