Preface

As Chinas demand for clean energy increasing day by day,imports of high - quality, clean, efficient and convenient

energy resources - liquid natural gas (LNG) has become a

important way to improve and optimize chinas energy

consumption structure, as well as ensure the energy supply

security and promote the protection of eco-environment.

Since the early 90s, China National Offshore Oil Corporation

(CNOOC) start to think about the inport of LNG strategically.Preparatory work of project management for this new

industry start later, including the research on international

LNG standards and codes.

Preface

LNG standard system including six parts: international

standards, state laws and regulations, LNG national standards,

LNG industry standards, enterprise standards and standards

relating to LNG construction.

It plays an important role in building jettys, terminals, storage

tanks, pipelines, util ities, providing contract quality

requirements of natural gas and LNG project management.

In the fol lowing, I wi ll introduce the experiences and practices

that the standardization management department of CNOOC

has had in the process of establishing nation/industry/

enterprise standard system of LNG while entering LNG industry.

1 Establishment of National and IndustrialStandard System for LNG Profession

1.1 Investigation of foreign LNG Standard System

Since the world's first LNG trade appear in the mid-20th century, the countries

have attached great importance to the development of relevant standards

including LNG production, storage and transportation, trade, measuring and

using, enhancing HSE management, avoiding the risk of HSE and ensuring the

healthy development of the LNG industry.

In Europe, the England, Germany etc, has promulgated standards concerning

the property of LNG product, LNG standards about fire protection, LNG

Materials standards, LNG equipment and facilities standards, measurement

standards and so on.

The U.S. has its own system on LNG standardization construction. U.S.

National Fire Protection Association (NFPA), American Petroleum Institute(API), American Society of Mechanical Engineers (ASME) set their own

standards on LNG fire protection safety, LNG production, storage and

transportation, processing, LNG equipment and materials standards

respectively.

Japan is the largest LNG importer in the world, accounting for

40% of the total import of the world. Japan has accumulated a

large number of LNG operation data. Japan Gas Association

(JGS), Japanese Industrial Standards (JIS), Japan Electric

Association and the Japan High Pressure Gas Safety Institute

contribute to the construction of LNG standardization respectively,and erect their own series of standards. Some of these standards

has also been applied in South Korea and China Taiwan region.

Standards in these countries, especially the standards of Europe

and the U.S. have been widely used in design, construction and

acceptance of CNOOCs LNG projects. It plays an important role in

the beginning of Chinas LNG industry.



8/42CNOOC Gas & Power Group

According to the condition of established LNGstandards in different countries, the ISO founded a LNG

standardization workgroup (WG10) in November, 2006.

The main work is to draft the standard for LNG facilities

and materials and to coordinate the LNG standards

which are famous and universal used in the world. Its a

very good method to track the international LNG

standards. The three big National petroleum companiesof China all send representatives to attend the WG10

steering committee.




The main work of WG10 workgroup is following:

a. To evaluate the need of standard and criterion of LNG indifferent countries.

b. To evaluate the applicability of existing international LNGstandards and criterions in LNG industry.

c. To ascertain the cooperation frame of the existing LNGstandards and criterions owners with workgroup.

d. To ascertain the order of standard establishment.

With the organization and coordination of WG10 LNG standardtechnical committee, the international LNG standard system will

gradually unify and perfect, which will promote the developmentof standardization of Chinese LNG industry. Table 1 was Thegathering standards of WG10 are from CENIBCIMONFPAASMEAPIIPCSADINBSJGA JISKHKKLKand so on.

1.2 The necessity of making national standard system OFLNG

1.2.1 The development of the LNG industry needs standards

The production of the global LNG is expected to increase from 300million tons in 2010 to 600 million tons in 2020, the related investmentof the construction of new gasification plant and liquefaction plan will

come to 1500 million -2000 million U.S. $ (at current prices), China is tobe the important importing country in respect of LNG.

The standard will be the common language among exporters, importers,investors, manufacturers, design engineering and users. It is also thebase of minimizing capital investment and ensuring safety.

At the technical level, new equipment ,new technology and new concept(marine LNGModule designFloating gasification system) appearcontinuously, the rational selection and application need thecorresponding standards and specification.




1.2.2 The standardization of internal LNG industry must accord

with the international standard.

There is mature technology and perfect standard during the LNG

industry abroad. Its a shortcut to refers to external advanced standard

directly to rapidly develop and boost the level of internal LNG industry.

As the first internal LNG pilot project, extensive research survey forexternal LNG standard, correlative jetty, receiving terminals, storage

tanks, pipelines and civilian building standard was actualized during its

preliminary research, design, construction and commissioning. The

LNG standard system table of our country that will become the

instructor of constituting the internal LNG industry standard henceforthis compiled. During the process, the internal standard is employed if

there is appropriate one. If there is not appropriate standard for LNG at

home, the foreign advanced one will be cited.




1.3 Nation and Industry the LNG standard system table

According to the above guiding concept and authorized pr inciple, especially

according to the LNG project practice in Guangdong and Fujian, the work

group has investigated the foreign LNG standard system systematically since

2000. The study consists of three stages. Firstly, we collected and gathered the

foreign standards. Secondly, the core standards are validated and translated.

Whats more, we investigated and compared the standards, and then wrote the

report.

So far, we have workout the third edition < The table of Nation and Industry

LNG Standard System >, as shown in table 2. In the table, the core criterion of

analyzing-measuring and product ion-storage/transportation are shown. Also,

the products standards and the HSE cri terion which were lack in China is paid

attention.

Until today, according to the system table, we have worked out several system

standards of nation and industry: seven volumes promulgated, one copy on

approval, nine reports for approval, one volume in formulation, three volumes

in the prior study, and the others in planning collect.

2 Establishment of the Enterprise StandardSystem for LNG Industry in CNOOC

2.1 LNG Enterprise Standard System Compilation

2.1.1 System Compilation

LNG Project management could be categorized into:

Previous Stage which consists of Market Investigation, Pre-feasibility Study,Feasibility Study and Project Establishment Application,

Middle Stage which consists of FEED, Detailed Design and Construction,Later stage which consists of Examination and Acceptance andCommissioning.

Current oversea standard and domestic project associated standard cant

satisfy the requirements of all the phases of LNG project, especially lacks

relevant standards of early stage, middle and later stage of projectmanagement which has Chinese characteristics. CNOOC takes the lead to

invest in construction of the first several LNG projects of China and gained

rich experience, which lays foundation for the compilation of enterprise

standards.

3.2 Standard System Classification

As the regular LNG engineering includes four parts: receiving terminal(including tank), jetty, pipeline, and utilities, the classification will be carriedout in accordance with function with this as the main line, e.g.

Jetty falls into: general chart, shipping, navigation channel, breakwater, jettyengineering, navigation channel safety;

Receiving terminal falls into: gasification technology, tank, equipment andinstallation, materials, manifold, metering;

Pipeline falls into: pipeline engineering, pipeline crossing, pipelineanticorrosion, electric communication, foundation anti-earthquake, firealarm;

Utilities falls into: construction structure, water supply and drainage, heatingand ventilating, building lighting, safety and environment, constructionfoundation etc.

The following could be divided into products, design and construction. LNGprofessional standards are 21, jetty 22, receiving terminal 661, tank 13,pipeline 98, HSE 328(see chart 2), altogether 1140.

4 Participate International Standardization WG10actively

Conducting LNG Standard System Study is the necessity in

Chinese LNG production and market, and its needful overseasand domestic situation development.

The situation requires LNG standard system to get integrated

into international cri teria, adjust correspondingly and create

Chinas own LNG standard system, and makes i t the

indispensable, internationalized and competitive LNG

standardization guiding documents in overseas and domestic oil

and gas markets. It can be utilized to speed up LNG industry and

standardization process and guide state, industry and enterprise

LNG standards enactment and revision in future.

In 2006, ISO set up LNG working team in T67 technology

commission which is of the same characteristic with our current

LNG sub-technology commission. Therefore, taking part in WG10

actively is very helpful.


31/42


32/42


As China is the member country and permanent member of ISO, together

with the fact that China is at preliminary stage of building LNG project based

on ISO and European and American .So we decide to take international

standard and overseas advanced standard like ISO, EN, etc. to erect

Chinas own LNG standard system.

Therefore, participating ISO/T67/WG10 is the main road to get our current

LNG standardization internationalized.

5 The Role of LNG Project Standard System inProject Quality Management

5.1 The Role of LNG Project Standard System in Project Quality

Management

5.1.1 The main Contribut ion of International/National LNG

Professional Standard

a. LNG Resources

LNG Resources are the foundation of project establishment application.

How to secure qualified LNG resources needs to regulate the

specifications by standard. Relying on LNG General Specification byISO resolves the issue of Specification and usage safety during

resources selection and provides important reference index for

resources negotiations.


36/42


b. LNG Tank Construction

LNG Tank is the key part of Project. China has never been involved in thisengineering before and lacks such kind of standards. Relying onCryogenic Temperature Vertical Flat Bottom Cylinder Type Tank by ISOEN standard and Design and Construction of Large Sized Welding LowTemperature Tank by American API standard and LNG Equipment andInstallation by European Union standard provide valuable design,

construction and acceptance regulations for LNG Project key engineering.

c. LNG Measurement

During commissioning process, LNG measurement must be consistent withinternational standard. We not only should pay attention to the LNGvolume and weight measurement but also should focus on LNG energy

value measurement, for different LNG composition could influence theenergy value is the main deciding factor of price. Currently, energymeasurement is generally used internationally and we select frominternationally used measurement standard so as to cooperate andcommunicate with international counterparts more easily.

b. Project Management

LNG project management is a comprehensive management process

relating to project progress, budget, quality and HSE. We cant 100% copyoverseas project management experience and practice, and have tosummarize and improve based on our own project practice so that we canuse it in our future LNG Project.

We are in the process of compiling LNG Project Management Manual basedon Dapeng and Fujian LNG Project practice, which wil l offer reference for

future LNG project quality management.c. LNG Project Acceptance

After invest igation and project running, we find post evaluation of LNGproject engineering completion and acceptance and LNG trunklinecompletion and acceptance also has no international reference. Therefore,we start to compile enterprise standards like LNG Project Engineering

Completion and Acceptance and LNG Trunkline Completion andAcceptance based on Dapeng an Fujian LNG project practice, which willprovide method and tools for project later stage quality management .

Currently, the receiving terminal, jetty and pipeline separate index of LNGProject Engineering Completion and Acceptance has been submitted toCNOOC headquarter for review and wi ll be released.

In short, International/State/Industry Standard and Enterprise standard

system cover different aspects of LNG project phases.

Currently, the international, state , industry and enterprise standard

system serials with respect to jetty, receiving terminal, pipeline andutilities basically cover each engineering and each phases of LNG

introduced project quality management .But state standard and

enterprise standard still need to be improved, especially the industry

standard need each enterprises companies who come into the LNG

industry concerted efforts.
