The world's first integrated LNG modular plant achieves full cap

On May 31, it was learned from Tianjin Port Free Trade Zone Enterprise Offshore Oil Engineering Co.
, Ltd.
(hereinafter referred to as "Offshore Oil Engineering") that the world's first integrated LNG (liquefied natural gas) modular plant built by China is the most important core process.
Module A1EC was successfully delivered in Qingdao, Shandong
.
So far, the Canadian LNG project undertaken by COOEC has successfully delivered 10 modules and completed the capping of all module structures
.
At present, the overall construction progress has exceeded 80%, laying a solid foundation for the project to be delivered on time
.

"The A1EC module delivered this time consists of four main decks, with a length of 78 meters and a width of 46 meters.
The deck area is equivalent to the size of 9 basketball courts, with a height of 50 meters and a height of nearly 18 floors.
The transport weight of the module is nearly 10,000 tons.
It is the heaviest LNG core process module delivered by the Qingdao Construction Base of COOEC so far
.
” According to Zhuang Hongchang, the Canadian LNG project manager, the A1EC module is mainly responsible for the dehydration and mercury removal of raw gas pretreatment, and is an extremely important module in the entire LNG plant.

.
The module contains a total of 5 large-scale equipment, the height of a single equipment is nearly 20 meters, and the installation level and standard accuracy are controlled within 3 mm, reaching the leading level of static equipment installation in the industry
.

Compared with traditional modules, A1EC modules have many characteristics such as large size, heavy tonnage, and many large-scale equipment
.
To this end, COOEC has formulated response strategies in a targeted manner, improved the management level of technical solutions, and strengthened safety, quality and progress control
.
For the first time, 7 rows of 13 groups of SPMT vehicles with 336 axes were used for combined transportation.
Before the formal loading operation, 3 simulation exercises were carried out, and 4 were formulated for extreme conditions such as abnormal vehicle conditions, incorrect data during transportation, extreme weather, and ships unable to berth.
During the transportation process, the commander-in-chief was designated to make overall arrangements for the 13 power heads, organize special personnel to monitor important nodes, implement hard isolation of the transportation path, and take multiple measures to ensure the smooth delivery of the modules
.
It is reported that there are also 4 pipe gallery modules delivered in the same batch as the A1EC module, which will be transported by the large semi-submersible ship "Xianghekou" to the Canadian project site 5,000 nautical miles away
.

This time, COOEC undertook the construction of 35 modules in the first phase of the Canadian LNG project, including all 19 core process modules, with a total weight of about 179,000 tons
.
Through repeated calculations, COOEC disassembled the project into 333 deck pieces, which were prefabricated in the workshop, and then carried on the slideway like building blocks
.
Facing the challenges of large quantity, heavy tonnage, and high technical requirements, COOEC established a special team to implement monthly rolling plans and special module plans, with the help of information technology, to fully promote the loading work, and finally realize the structural capping operation of all modules as planned.

.

In order to practice the concept of "clean manufacturing, quality first", the Canadian LNG project has established an FPD (Defect-Free Delivery) team to strengthen process quality control and material protection, and implement refined management in every construction link
.
In addition, the Canadian LNG project has pioneered the large-scale engineering application of the new NBG (no back shielding gas) welding process in the world.
While the on-site welding pass rate is 2% higher than that of the same type of welding operation, it has significantly improved the large-diameter stainless steel.
Pipeline construction safety, greatly improving welding efficiency
.

The Canadian LNG project is the largest energy investment project in Canadian history.
It plans to build 4 production lines, of which the first phase of the project plans to build 2 production lines with an annual output of 13 million tons
.
After the project is completed and put into operation, it will supply high-quality liquefied natural gas to the Asian region, which is conducive to the diversification of China's natural gas import channels
.
In addition, for the first time in the world, the project has realized the integrated construction of core process modules and pipe gallery modules, and created a number of new processes and technologies, marking that China's LNG modular plant construction capacity has steadily ranked at the international advanced level
.

Yu Yi, Chairman of Offshore Oil Engineering Co.
, Ltd.
, said that the Canada LNG project is another super-large core process module construction project undertaken by COOEC following the successful delivery of the world's first polar LNG project in 2017, the Yamal project.
COOEC's LNG high-end modular construction capability has ranked first in the international industry
.
In the future, COOEC will continue to build the technical system and service capabilities of the whole industry chain of LNG engineering.
While helping the Tianjin Port Free Trade Zone to build a pilot area for the manufacture of high-end offshore equipment and facilities, it will also promote more "high-end manufacturing" in China to go out and serve the world.
Green and sustainable development contributes to China's strength
