Preface

As China’s 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 china’s 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.


PrefaceLNG 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, utilities, providing contract quality requirements of natural gas and LNG project management.In the following, I will 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 Industrial Standard 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 standardsincluding LNG production, storage and transportation, trade, measuring andusing, enhancing HSE management, avoiding the risk of HSE and ensuring thehealthy development of the LNG industry.

In Europe, the England, Germany etc, has promulgated standards concerningthe property of LNG product, LNG standards about fire protection, LNGMaterials standards, LNG equipment and facilities standards, measurementstandards 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 ownstandards on LNG fire protection safety, LNG production, storage andtransportation, processing, LNG equipment and materials standardsrespectively.


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 Institutecontribute 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 CNOOC’s LNG projects. It plays an important role in the beginning of China’s LNG industry.



According to the condition of established LNG standards 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. It’s a very good method to track the international LNG standards. The three big National petroleum companies of 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 in different countries.

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

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

d. To ascertain the order of standard establishment.

With the organization and coordination of WG10 LNG standard technical committee, the international LNG standard system will gradually unify and perfect, which will promote the development of standardization of Chinese LNG industry. Table 1 was The gathering standards of WG10 are from CEN、IBC、IMO、NFPA、ASME、API、IP、CSA、DIN、BS、JGA、 JIS、KHK、KLK and so on.

1.2 The necessity of making national standard system OF LNG1.2.1 The development of the LNG industry needs standardsThe production of the global LNG is expected to increase from 300 million tons in 2010 to 600 million tons in 2020, the related investment of the construction of new gasification plant and liquefaction plan will come to 1500 million -2000 million U.S. $ (at current prices), China is to be 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 the base of minimizing capital investment and ensuring safety.

At the technical level, new equipment ,new technology and new concept (marine LNG、Module design 、Floating gasification system) appear continuously, the rational selection and application need the corresponding 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. It’s 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 for external 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 henceforth is 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 tableAccording to the above guiding concept and authorized principle, 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. What’s 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 production-storage/transportation are shown. Also, the product’s standards and the HSE criterion 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 Standard System 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 and Commissioning.

Current oversea standard and domestic project associated standard can’t satisfy the requirements of all the phases of LNG project, especially lacks relevant standards of early stage, middle and later stage of project management 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.


2.2 CNOOC LNG Enterprise Standard System

2.2.1 LNG Enterprise Standard System Table

With respect to the detailed part of Technology, Management and Work, especially those relating to quality management program and detailed technology requirement of LNG project plan, it can only be accomplished by reinforcing Enterprise Standardization based on enterprises’ actual situation.

Target market investigation of LNG project location, project application report, project management, engineering design, bidding, project acceptance and post-appraisal etc. all lack national and industry standard.

Therefore, we compile CNOOC’s LNG Enterprise Standard System(Table 3) in the hope of establishing enterprise standards available for reference for all parts from project establishment application to its completion and meet the requirement of industry development.

4 Participate International Standardization WG10 actively

Conducting LNG Standard System Study is the necessity in Chinese LNG production and market, and it’s needful overseas and domestic situation development.

The situation requires LNG standard system to get integrated into international criteria, adjust correspondingly and create China’s own LNG standard system, and makes it 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.


Erect internationalized Chinese LNG Standard System is a systemized project, “Standard Selection” must be based on “Standard Selection System” and try to keep consistent with LNG standard system with “Standard Selection”, especially those regional standards selection.

During the standard selection, process, selecting from which country and which series is always the difficult facing us.

Developed countries have a variety of LNG standards, such as European, American, British, Norway, French, Japanese, and so on. Also they have ISO、EN、API、ABS、DNV、IEEE、ASTM、ASME, etc.

Although they are dealing with the same technical issues, some of these standards are stricter in some aspects, others are stricter in some other aspects.

How to select to lower engineering costs as well as mitigate risks and confine the risks to certain level requires a great deal of investigation, there is no exception with the standard selection of System.

Japanese LNG standards system, whether it’s advancement, safety or its practicality or effectiveness, is non-disputable, but it can’t be used for it has its own system and not consistent with ISO and European and American standard system, so we have to abandon it as the reference standard.

Of course, as previously stated, concrete enterprise should use them as reference when they are formulating certain individual standards or state and industry standards.



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

China’s 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 in Project Quality Management

5.1 The Role of LNG Project Standard System in Project Quality Management

5.1.1 The main Contribution 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 by

ISO resolves the issue of Specification and usage safety during

resources selection and provides important reference index for

resources negotiations.


b. LNG Tank ConstructionLNG Tank is the key part of Project. China has never been involved in this

engineering before and lacks such kind of standards. Relying on Cryogenic Temperature Vertical Flat Bottom Cylinder Type Tank by ISO EN standard and Design and Construction of Large Sized Welding Low Temperature Tank by American API standard and LNG Equipment and Installation by European Union standard provide valuable design, construction and acceptance regulations for LNG Project key engineering.

c. LNG MeasurementDuring commissioning process, LNG measurement must be consistent with

international standard. We not only should pay attention to the LNG volume and weight measurement but also should focus on LNG energy value measurement, for different LNG composition could influence the energy value is the main deciding factor of price. Currently, energy measurement is generally used internationally and we select from internationally used measurement standard so as to cooperate and communicate with international counterparts more easily.



5.1.2 The Main Contribution of CNOOC LNG Enterprise Standard a. LNG Project Prophase Study

As China is different in its national conditions, we don’t have any oversea standards for reference when conducting LNG project prophase site selection and report to the national competent departments for approval.

Enterprise standards which are being compiled and developed are: LNG Project Site Selection Report Compilation Instructions, LNG Project Pre-feasibility Study Compilation Instructions, LNG Project Feasibility Study Compilation Instructions and LNG Project Application Report Compilation Instructions, which regulate the compilation contents and format of the prophase serial report and have guiding significance to prophase work.



b. Project Management LNG project management is a comprehensive management process relating to project progress, budget, quality and HSE. We can’t 100% copy overseas project management experience and practice, and have to summarize and improve based on our own project practice so that we can use it in our future LNG Project. We are in the process of compiling LNG Project Management Manual based on Dapeng and Fujian LNG Project practice, which will offer reference for future LNG project quality management.

c. LNG Project AcceptanceAfter investigation and project running, we find post evaluation of LNG project engineering completion and acceptance and LNG trunkline completion 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 and Acceptance based on Dapeng an Fujian LNG project practice, which will provide method and tools for project later stage quality management . Currently, the receiving terminal, jetty and pipeline separate index of LNG Project Engineering Completion and Acceptance has been submitted to CNOOC headquarter for review and will 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 and

utilities 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 enterprise’s companies who come into the LNG

industry concerted efforts.

6 ConclusionDuring the pioneering period of China’s LNG industry, selecting foreign standards and regulations suitable to China’s national conditions and establishing state standard system and then directly select standard or modify selected standard by extensive investigation and comparison of international industry standards is the shortcut to compile Chinese state standards.

From actual situations of LNG project quality management and based on the technical and management experience, compiling LNG enterprise standard at this right time is the proved and effective way to remedy the shortage of state standards and overcome complex process which is characterized by long process from project establishment application to approve and release, and effective way to supplement enterprise standard of LNG project management in time.

Industry standards is the achievement reached by all the enterprises which has gained access to LNG industry. Industry standards is the regulation to regulate industry technology and management behavior, and the inevitable way to expedite speedy development of China’s LNG industry.

In a word, the improvement of China’s LNG industry relies on the establishment and perfection of state, industry and enterprise LNG standards.
