CNOOC announced today that Asia’s first cylindrical “offshore oil and gas processing plant” independently designed and built by my country, the “Offshore Oil 122” floating production, storage and offloading unit, has completed its main construction in Qingdao. This marks the completion of the main body of my country’s The design and construction technology of all types of floating production, storage and offloading units has achieved a high level of autonomy.
The main body of Asia’s first cylindrical “offshore oil and gas processing plant” is completed
CCTV reporter Zhang Congjing: This is the Qingdao Marine Engineering High-tech Equipment Manufacturing Base. With the last module hoisted into place on site, it means that after 20 months of construction, this new type of equipment integrates crude oil production, storage, export and other functions. The main structure of the “Offshore Oil and Gas Processing Plant” has been completed and has entered the integrated commissioning stage.
The main body of “Haiyang Shiyou 122” is composed of two parts: the hull and the upper functional module. The diameter of the hull is about 90 meters. The main deck area is equivalent to 13 standard basketball courts. The design displacement is 100,000 tons, the maximum oil storage capacity is 60,000 tons, and the design life is 30 years, and can operate continuously at sea for 15 years without returning to the dock for maintenance.
Tao Fuwen, General Manager of Offshore Petroleum Engineering (Qingdao) Co., Ltd.: Innovatively adopting integrated construction technology and double gantry crane integration technology to realize the independent application of 15 key technical equipment, giving our country the ability to independently design and manufacture different types according to different oil fields and different sea areas. capabilities of deepwater oil and gas equipment.
“Offshore Oil 122” is planned to be completed in the first half of 2024. After completion, it will serve the Liuhua Oilfield in the Pearl River Mouth Basin, providing a new option for the economic and efficient development of my country’s deepwater oil and gas fields.
Revealing what’s in the “Super Energy Bowl”
This cylindrical “offshore oil and gas processing plant” is vividly called the “Super Energy Bowl”.
CCTV reporter Zhang Congjing: This is the construction site of the “Super Energy Bowl”. Look at this big thing. It is more than 60 meters high. Most of the workers are currently working on the top. How do you have to reach such a high position? For homework, I have to climb up the yellow vertical tower next to me, and we also go up to have a look.
CCTV reporter Zhang Congjing: When I walked into the Energy Bowl, I found that there were steel pillars all over the place. As you can see from the aerial footage, it is piled with cubes of different sizes and shapes. They are called “functional modules” and are the core devices of the energy bowl. They are responsible for different tasks such as oil and gas processing, living and office, etc. The staff told me that assembling these modules is actually like building blocks. They are hoisted up in one piece. Each module weighs more than a thousand tons and needs to be accurately lowered from an altitude of nearly 100 meters. The assembly gap is It’s less than ten centimeters, and there can’t be any scratches. You can imagine the difficulty. I am now at the joint between the two modules. You see, after installation, the gap between the two modules is not as wide as my palm.
Chang Xiaolong, General Assembly Integration Manager of CNOOC’s “Offshore Oil 122”: We use a digital system to control these two large gantry cranes to operate simultaneously. We innovatively use tip-assisted positioning technology. The tips are at the bottom of each module. There are more than a dozen prongs, and we finally controlled its positioning accuracy within 4 mm. Our method also speeded up the overall operating efficiency. On average, one module was lifted every two days, and the overall operating efficiency increased by more than 50%.
CCTV reporter Zhang Congjing: You can see that the space in the energy bowl is very narrow, because these modules are composed of hundreds of thousands of parts and are highly integrated. Let’s take a look at a construction site now. The master workers are laying cables here. They have to squat and move like this to complete these operations. I found that in fact, difficult construction like this involves almost all types of work.
Zhang Xianbin, deputy manager of CNOOC’s “Offshore Oil 122″ construction management: There are currently nearly 1,000 people working here, and the number will further increase during peak periods. They work in 24-hour shifts to carry out intense work such as the connection, integration and debugging of some mechanical equipment to ensure that ” The “Super Energy Bowl” was completed with high quality and provided deep-sea equipment for energy powers.
Digitalization empowers offshore oil and gas equipment manufacturing
During the construction process of the “Super Energy Bowl”, a large number of digital technologies were applied to help the project progress faster, and the safety, quality and precision control levels were significantly improved.
Since the weight of the module exceeds the limit of the gantry crane, the “Super Energy Bowl” innovatively adopts the joint lifting method of double gantry cranes. However, the drives and speed modes of the two cranes are different, making efficient synchronization a problem. The project independently developed a dual-crane joint control digital management system. The crane driver can complete precise and synchronized operations of two gantry cranes while sitting in the same cab, greatly improving operating efficiency and safety levels.
Ma Lin, construction engineer of CNOOC’s “Offshore Oil 122”: The self-developed sea-land integrated intelligent central control system can switch to typhoon mode when a typhoon approaches, realizing unmanned production during the typhoon, and contributing to the intelligentization of offshore oil and gas field facilities. and digital construction provide a brand new model.
During the peak period of the “Super Energy Bowl”, there were nearly 1,000 construction workers, with many restricted spaces and high safety risks. The project developed an “intelligent personnel positioning system” with multiple functions such as precise positioning, static alarm, and one-click rescue, which can be tracked in real time. On-site worker dynamics. At the same time, a series of digital technology methods have been widely used in project design, construction, quality management and other aspects, providing a powerful digital driver for the efficient advancement of the project.
Ran Xiangpeng, deputy construction manager of CNOOC’s “Offshore Oil 122”: Through the application of digital technology, it only took 20 months from the start of construction to the completion of the main body. Compared with cylindrical production units of the same scale in the world, the construction period has been shortened. Half, the first-time quality pass rate reaches 99%, and the main dimensional accuracy of the hull reaches the world’s advanced level.
