The world's first integrated construction of LNG modular chemical industry has been completed and delivered

On March 7, the delivery of the last two core modules of the Canadian LNG (liquefied natural gas) project undertaken by Offshore Oil Engineering Co., Ltd. The AWP (Advanced Work Package) special award awarded by the Construction Industry Association marks the delivery of all 35 modules of the world's first integrated LNG plant.

It is reported that the Canadian LNG project is a world-class LNG project jointly invested and constructed by Shell and other five major international oil companies in the world. The first phase of the project plans to build two production lines with an annual output of 14 million tons of LNG. After completion and operation, it will supply high-quality clean energy to China and other Asian countries, which will help promote the diversification of my country's natural gas import channels.

According to Zhuang Hongchang, Canadian LNG project manager, COOEC undertook the construction of 35 modules in the first phase of the Canadian LNG project, including all 19 core process modules, consisting of more than 770,000 structural parts, with a total weight of about 179,000 tons, equivalent to The weight of the steel structure of nearly three Burj Khalifa, the world's tallest building, and the total length of the cables are 1,270 kilometers, which can circle the Beijing Sixth Ring Road nearly seven times. The project is the world's first integrated construction mode of core process modules and pipe racks, which greatly improves the integration of module construction and minimizes the workload of on-site installation. On the one hand, it can save the floor area of the construction site and improve economic benefits. Protection also has clear advantages.

It is understood that the Canadian LNG project is large in size, heavy in module weight, and highly integrated. The largest module weighs more than 8,200 tons, which exceeds the total weight of the steel structure of the Eiffel Tower. 283 sets of large-scale equipment, 33 modules are assembled at the same time during the peak period, nearly 8,000 construction personnel, and more than 130,000 construction management units are involved. Project management, construction technology, large-scale equipment resources, precision control, etc. have all been put forward severe challenge. In addition, as a highly international project, the Canadian LNG project involved 127 suppliers from 12 countries. The construction process encountered an unprecedented global new crown virus epidemic, which had a major impact on the implementation of the project as planned.

According to Liu Kai, the executive deputy manager of the Canadian LNG project, the project carried out comprehensive technological and management innovations, realized the large-scale engineering application of the new NBG (no back shielding gas) welding process for the first time in the world, and pioneered the realization of CMS (Construction Management System) + PCMS ( Project management system) dual-system joint management, the first time in China to apply 4D visualization technology to the construction of LNG core process modules, and complete SPMT (self-propelled module transport vehicle) jacking assembly, large-scale structure hoisting, double-precision dimensional control, central control cloud More than 10 technological innovations, such as commissioning and process system degreasing, have greatly improved the level of digital and visualized construction technology and project management efficiency, and completed the delivery of all modules with high quality on schedule under the severe epidemic situation, showing the "China Speed" to the world. The project takes "zero defect" as the quality goal. Through the comprehensive and whole-process quality management of all employees, the quality pass rate of all items exceeds the requirements of the owner's specification. The positioning accuracy of static equipment is 3 mm, and the soft foot test accuracy of dynamic equipment is 0.03 mm. Reach the world advanced level.

At the beginning of the construction of the Canadian LNG project, the safety and health of employees were put in the first place, and it was committed to creating "the safest project in the world". COOEC cooperated with all participating units to systematically create a project-specific safety culture, and applied a large number of informatization The management method has created a record of 43.76 million safe working hours in the world for the highest safe working hours of LNG modular construction. "During the nearly 40-month construction period, through solidarity, cooperation and excellent leadership, every possible injury was avoided and a commendable safety record was achieved, which is an achievement worthy of being recorded in history." Project General Contractor Representative Fang, JGC Group President and Chief Operating Officer Ishizuka praised.

During the implementation of the Canadian LNG project, COOEC actively promoted the localization of the project by recommending domestic manufacturers, leading the owners to inspect the manufacturers, inviting authoritative certification from international third-party organizations, etc., and achieved an overall localization rate of 65% of the main materials of the project. More than 60 Chinese manufacturers "going out" with COOEC.

It is reported that the Canadian LNG project is another super-large international energy equipment successfully delivered by COOEC within 4 months after delivering the largest cylindrical FPSO built in my country——Penguin FPSO. High-quality business cards "Made in China".
