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 worlds LNG plants.

This has included completing a pioneering project to

conduct a pre-FEED study for one of the worlds 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 GLs 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 GLs 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 LNGs potentialLNG is capable of bringing previously inaccessible gas

reserves to market, but the demand on the developing

technology is high. DNV GLs 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 GLs 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 GLs 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 worlds 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.

operators to reduce and manage risk, and to ensure a

successful project outcome. Guided by our assessments

of inherent risks, we support our customers from the very

beginning of a project. Our global network of experts

focuses on reducing operating costs, while maintaining an

acceptable level of reliability and safety.

Taking the industry forwardDNV GL has created a series of internationally recognised

standards, service speciications and recommended practices together with the pipeline industry. Our irst pipeline code (DNV OS-F101) was issued in 1976. It has

achieved global recognition, winning industry awards and

currently 65% of all new projects globally are designed to it.

DNV GL believes that technological development will play

a key role in driving energy sustainability and industry

best practice along the gas value chain. We have

a long-standing focus on industry measurement,

compliance and energy security, as well as investment in

solutions relating to energy optimisation and operational

eficiency. This enables us to provide operators with 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

technology demonstration to advice on operational

excellence. We provide expertise for technical assurance,

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 worlds 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.
