On October 2, on the MP-156 site of Bab Buhasa Oil Area, Bab Buhasa AiP5 production project of CPECC Gulf Region Company, bulldozers were roaring and earthmoving works were in full swing. "The CPECC team is a reliable partner with strong execution, verbal commitment and results in action." Wael Saleh Almessabi, Vice-president of ADNOC Onshore, spoke highly of the CPECC team's project management and schedule control capabilities.

The Bab Buhasa AiP5 production project undertaken by CPECC is ABU Dhabi National Oil Company's (ADNOC) ultra-large surface oil field EPCM project, which is also its breakthrough attempt in the field of AI numerical control. The project covers 3,980 square km in Bab and Buhasa oilfields, including 80 ADNOC Onshore Bab and Buhasa oilfields, the renovation and expansion of nearly 600 oil, water and gas Wells and 1,000 km of new long haul pipelines. Once operational, it will increase production by 116,000 BPD at Bab and 141,500 BPD at Buhasa.

"After the project is completed, we will be able to remotely control Wells hundreds of kilometers away from the central processing station." Mohammed Saleem Abbasi, regional construction manager for the AiP5 project inBuhasa, Gulf Region Company.

Build and share to play a "precise card"

As the centerpiece of ADNOC's P5 plan to increase production to 5 million BPD by 2027, the AiP5 project is based on the new EPCM project model, actively communicating with the owner, constantly exploring innovation, and improving as it is implemented.

Facing the great challenge of full production in 2027, the AiP5 project team accurately grasped the needs of the owners, proposed an innovative concept of "first oil", and worked out a phased and batch production plan with the owners, which not only realized the operation of some Wells more than one year in advance, and created additional economic benefits for the owners. It also has laid a solid foundation for the acceleration of the AiP5 project.

The EPCM model pays more attention to the flexibility and adaptability of the project, and the project team is not only the executor, but also the "technical consultant" who covers the design, procurement, construction and management.

Drawing on CPECC's rich experience in construction organization, the AiP5 project team proposed to divide the construction subcontracting into 9 main parts and select large and powerful subcontracting units with deep qualifications to cooperate. While the owner initially preferred multiple subcontractors to reduce costs, as the project model review and procurement work progressed, the owner gradually recognized the complexity of interfacing with multiple subcontractors and agreed to streamline subcontractors. This decision not only simplifies the business bid evaluation process, improves the overall progress of the project, but also strengthens the control of the project quality.

Strong foundation and solid foundation Draw “concentric circles well”

Compared with EPC projects, EPCM projects lack the detailed guidance of the FEED (Front-End Engineering Design) stage, which is like drawing on a blank sheet of paper and stimulating creativity with only a few keywords. ADNOC's high requirements for process design, especially process simulation and hydraulic calculations, have created unprecedented challenges for the project team.

In order to avoid the adjustment of the design stage affecting the subsequent procurement and model review progress, the project team set up a detailed design team led by the process office of the Beijing Branch to quickly start the preliminary process design, summarize and share experience in time, and accelerate the adaptation process of the new ADNOC Standard (AGES). In addition, the AiP5 project for the first time tried to conduct commercial bid evaluation and order some materials simultaneously when the design accuracy reached 50%, and continued to improve the design drawings and add materials successively. This innovative working mode not only meets the requirements of precision in design, but also improves the efficiency of project operation.

In Bab and Buhasa, two old oil fields that have been in operation for more than 60 years, the AiP5 project faces particularly difficult challenges. The laying of 1000km new long distance pipeline not only solve the technical problems such as large line span and many old pipe lines crossing, but also deal with the interference of external parallel projects. In order to improve efficiency, the project team and the Beijing Branch studied the ADNOC construction procedure documents in depth, identified the key nodes requiring the intervention and coordination of the owner's interface department, and prepared a set of standard flow chart that clearly planned the work content and completion time of each link, and confirmed it with the owner, subcontractors and external parallel project parties. Turn passive work into active collaboration.

"This experience has been both a challenge and a valuable experience, and we now have the ability and confidence to tackle any project or design challenge." Beijing branch Aip5 project design deputy manager Wang Jinjie firmly said.    

Gather strength and transform to play the "main melody"

With the rapid development of the ADNOC P5 production increase program, the manpower and material resources in the UAE market are becoming increasingly tight. In order to gain an edge in the fierce market competition, the owner required the AiP5 project team to complete the arduous task of compiling the entire EPCM project pre-planning package within two months. This includes not only project investigation, risk analysis, cost estimation, but also design, procurement, construction and plan management, which runs through the entire project execution cycle, and the workload is huge.             

Faced with the challenge, Zhang Fan, manager of AiP5 Project Control Department, led three foreign employees to work together, discuss the details of the plan with the owner during the day, and work overtime at night to adjust the plan package. Within 60 days, more than 2,600 pages of the plan package were completed according to the node. "The owners were amazed at how efficient our team was, and the fact that four of us did what would have taken at least 10 people to do was a huge boost for our entire team." Zhang Fan is full of praise for each member of the project team, he said proudly, "Always ahead of the task, is the firm belief of our team."       

Kaleem Aziz, a Pakistani national, has worked for several international companies and joined CPECC in 2017. With his outstanding professional ability, he serves as the interface Manager of Aip5 project. He is busy communicating with people from different countries and different business areas every day to organize and coordinate complex interface interchanges. In the face of endless difficulties on the scene, Kaleem said cheerfully: "Every time I successfully solve the problem, I feel very proud." He compared the Chinese team to a big family, which is closely united and working together to achieve goals.

Over the past year, AiP5 project has not only completed the contract milestone several times ahead of schedule, but also won the trust of the owner with high quality and high standards, and the scope of project work has been extended four times.

From an initial team of a few dozen people to an international team of more than 500 employees from more than 20 countries, AiP5 project has opened up a new situation in the reform, The theme of harmonious development of "respect, equality, openness, inclusiveness and integration" has been played overseas, and built a team full of identity, belonging and cohesion. In promoting transformation and upgrading and exploring the road of digital empowerment, we continue to move forward.

---- Kuwait Wara project

(17 January 2019)

Twenty years ago, I struggled to pay my tuition. Twenty years later, caution returns. This visit to the scene, experience hardships, feeling confident. Write down the words.

The sky is yellow with flying sand.

The sun and moon were without light.

Welding flowers disorderly dance in the crowd, machine sound, high morale.

A brother's heart is not old, but his days are unique.

Once shed tears and returned home temporarily.

A few degrees of hesitation.

For many years, until now, and then change military uniform.

The road ahead is still bumpy, and happiness will be long.

Note: In 1996, the company entered the Kuwaiti petroleum engineering market, and there were no follow-up projects after the completion of the oil gathering station project. In 2017, we won the bid for the Kuwait Wara project and returned to the Kuwaiti market.

---- feeling that the company's gulf engineering construction project is difficult

(19 October 2019)

The bay for a few days, heard and witnessed, mostly talked about, the prospect is worrying, looking back on the way, sigh to deep.

The high end of the grind.

For years, the pain continues.

Crawling in the desert.

Bitter tears and who sued.

A few days to see the sad.

Exhausted thinking, gradually know the cause of error.

Don't forget the wind and rain.

Usher in the world worry-free eyes.

Note: The Gulf project here generally refers to the UAE, Kuwait, Qatar and other projects. High-end refers to the high-end engineering market, which refers to the Middle East and other markets that have long implemented Western standard systems and have been monopolized by Western petroleum engineering companies for a long time

Ⅰ. Definition of pipeline transportation
Pipe transport is a means of transporting liquid, gas or semi-solid material through a pipe. This mode of transportation uses a large pipe system, usually made of metal or plastic, to connect the distance between the supply station and the end user. Pipeline transportation can be used for many different applications, including oil, gas, water, chemicals, and other types of fluid transportation. In some applications, pipeline transportation can provide an efficient, fast, and safe means of delivery while reducing environmental impact and costs.

Ⅱ. Pipeline transportation can be classified according to the transportation method of liquid, gas or semi-solid material. According to the different media, pipeline transportation can be divided into the following categories:
Oil pipelines: Used to transport liquid oil products such as crude oil and petroleum products to storage tanks, refineries and end users.
Gas pipeline: used to transport gas and other gaseous fuels to cities, factories, fertilizer plants and other places to supply heat and fuel.
Water pipeline: used to transport clean water, sewage and other water resources to urban, rural and other places to supply residents with drinking, production and irrigation.
Chemical pipelines: Used to transport dangerous goods such as chemicals and liquefied gas to chemical plants, industrial fields and end users.
Other types: In addition, there are also some special purpose pipes, such as conveying powder, semi-solid materials pipeline system.

Ⅲ.  Advantages of pipeline transportation industry
1. High safety: pipeline transportation facilities and maintenance are highly regulated, and independent pipeline systems are not susceptible to external influences. In contrast, other modes of transport, such as roads and railways, are more susceptible to accidents or bad weather.
2. Good environmental protection: pipeline transportation can reduce greenhouse gas emissions and noise pollution. In contrast, other modes of transport such as cars, planes, etc., produce more exhaust gases and noise, causing a greater burden on the environment.
3. High transportation efficiency: pipeline transportation is fast and can transport a large number of materials in a short time, compared with other modes of transportation may take longer to complete the same amount of goods transportation.
4. Low operating costs: because the pipeline investment is relatively high, but the operating cost of pipeline transportation is relatively low, a construction can be used for a long time, saving human and material resources.
5. Long distance transport: pipeline transport is suitable for long distance or multi-node transport. In contrast, other modes of transport require transit points, adding steps to transport as well as costs.

Ⅵ. Pipeline transportation development history
Pipeline transportation as an efficient, safe and environmentally friendly mode of transportation, its development can be traced back to 3000 BC in India and China. Ancient India and China used materials such as bamboo and copper pipes to build ditches and waterways to transport water and irrigate farmland in the early days. The construction of water and sewage pipes also began in the Greek and Roman periods. In the late 18th and early 19th centuries, with the rapid development of coal, railways and industrialization, people began to use pipe systems made of wood and cast iron to transport gas and water.
At the beginning of the 20th century, North America began to use advanced technologies such as steel pipes and welding technology to establish large-scale natural gas transmission pipelines, thus meeting the needs of industrial and urban gas. Since then, pipeline transportation has continued to develop and expand, and the scope of application has gradually expanded. With the development of science and technology, the use of new materials such as polymer materials and composite materials makes pipeline transportation safer, more efficient and environmentally friendly. At present, pipeline transportation has become an important mode of energy and materials transportation, and it is developing and growing.

Ⅴ. Pipeline transportation industry chain
Upstream refers to the exploitation and production of oil, natural gas and other energy resources, also known as exploration and development. In the upstream link, it mainly includes exploration, development, production and treatment processes. Midstream refers to the transportation of energy resources such as crude oil and natural gas from the collection point to the processing site or transfer station. The midstream link usually consists of transportation facilities such as pipelines and ships. Downstream refers to refining, chemical, heating and other consumption links, in this stage, the need to convert crude oil, natural gas and other energy resources into more kinds of products such as gasoline, diesel and basic chemicals.

Ⅵ. Scale of pipeline transportation industry
By the end of 2020, the total length of global crude oil pipelines exceeds 950,000 km. In the global crude oil delivery volume, crude oil pipelines in the United States and Canada dominate, followed by the Middle East; The total length of natural gas pipelines in the world is more than 500,000 kilometers. Countries such as Russia, China, the United States and Canada have large gas pipeline systems; The total length of petrochemical pipelines in the world exceeds 500,000 km. North America and Europe are the largest petrochemical pipeline markets in the world, accounting for more than 70% of the global market share. The total length of the world's water pipeline is more than 200,000 kilometers. Europe and North America are leading the way in water pipeline construction. Liquefied natural gas pipeline is a new type of pipeline in recent years. At present, the total length of LNG pipelines in the world is about 100,000 kilometers. Countries such as Australia, Qatar and the United States are among the world's largest LNG producers and have large LNG pipeline systems.
The total value of China's pipeline transportation industry in 2020 is 1.70 trillion yuan (about 260 billion US dollars). Among them, oil and gas pipeline transportation is the main field, occupying the vast majority of the market share, and continues to develop steadily. As the pipeline transportation industry belongs to the infrastructure industry, its profitability is relatively low, but on a stable and reliable basis, it can provide long-term stable cash flow. Therefore, pipeline transportation companies tend to have strong asset values and are considered to be one of the sound choices in the investment field.

The Opinions on Accelerating the Structural Adjustment of the Petroleum and Chemical Industry propose to promote the structural adjustment of the petroleum and chemical industry and improve the technical level and competitiveness of the industry by promoting pipeline transportation, developing new materials, and improving the efficiency of resource utilization.

Ⅷ. Development obstacles and challenges of pipeline transportation
1. Insufficient capital investment: Pipeline transportation construction requires a large amount of capital investment, but due to the long investment return cycle, as well as fierce market competition and other reasons, a considerable part of private capital may choose other more attractive industries to invest.
2. Imperfect management and supervision system: In the field of pipeline transportation, the perfection of management and supervision links plays a crucial role in the safety and reliability of the entire industrial chain. However, because pipeline transportation involves the coordination and management of many departments, its supervision and standardization still have a large room for improvement.
3. Lack of technological innovation: the current pipeline transportation technology has been very mature, but compared with other fields, the speed of technological innovation is slower, especially in the pipeline materials, sensor technology and other aspects of the research still need to be strengthened.
4. Increasing environmental pressure: the impact of pipeline transportation on the environment can not be ignored, especially the leakage of oil and gas pipelines may cause pollution to ground and groundwater resources, bringing risks to the ecological environment.
5. External factors interference: Pipeline transportation is also affected by external factors such as policy, geographical and international markets, such as international trade disputes, political conflicts and natural disasters.

Ⅸ. With the increasing global energy demand and the increasingly stringent requirements of various countries for environmental protection, the development prospects of pipeline transport are still broad.
1. The natural gas market potential is huge: in China, the medium - and long-term natural gas development plan proposes that natural gas consumption will account for 10% of total primary energy consumption by 2020, and will reach 15% by 2035. Globally, due to the increasing demand for clean energy and the increasing use of alternative fuels, the natural gas pipeline transportation market is expected to witness further growth.
2. Increasing demand for remote water resources transportation: With the continuous advancement of urbanization, the shortage of water resources has become one of the main problems facing urban development. In desert or mountainous areas with abundant water resources, water resources need to be deployed across regions through pipeline transportation technology, which also brings new opportunities to the pipeline transportation industry.
3. The application of new materials, sensor technology, etc. : New materials and sensor technology in the field of pipeline transportation can effectively improve the safety and reliability of pipelines, as well as reduce the maintenance and operating costs of pipelines. For example, nanotechnology can effectively improve the strength and corrosion resistance of pipeline materials.
4. National Policy support: The Chinese government has made natural gas one of the clean energy sources with the highest priority, and has formulated a series of policy measures to strengthen the planning and management of the gas industry. In addition, there are more and more countries or regions in the world regard the pipeline transportation industry as one of the important parts of infrastructure, and are willing to provide long-term stable financial support.
In summary, the pipeline transportation industry still has a broad space for development in the future. However, in the development of market prospects, it is necessary to take into account environmental protection, resource development efficiency, policy support and other factors to achieve sustainable development.
