The heaviest international offshore oil and gas platform built by China, weighing 17,000 tonnes, was officially delivered after 34 months of construction in Qingdao, east China's Shandong Province on Monday, marking a breakthrough in the country's large-scale offshore oil and gas equipment construction technology.
At the end of this month, the platform will be transported by a large cargo ship to its installation site, 6,400 nautical miles away, in the waters of Saudi Arabia. The platform is mainly responsible for collecting extracted offshore oil and gas and transporting it to land for processing. It consists of complex equipment such as large manifolds, pipeline cleaning, chemical treatment, and operation control.
The deck area of the giant platform is equivalent to 15 standard basketball courts and the height of the platform is higher than that of a 24-story residential building. The massive structure can collect and transport 24 million tonnes of crude oil and 7.4 billion cubic meters of gas every year, with platform scale, pipeline types and sizes, and system complexity all setting records on similar international platforms.
"We independently developed an intelligent management platform, innovated an integrated and visual construction model, and widely applied advanced methods such as automatic welding of composite materials and phased array ultrasonic inspection to improve management and address technical problems. Our management efficiency, construction efficiency, quality pass rate, and safety performance have reached the world's advanced level," said Liu Rui, general manager of COOEC International Engineering Company.
The platform will be installed in the waters of Saudi Arabia to help the Marjan oilfield increase its production capacity. After the Marjan oilfield is fully operational, the annual crude oil production will reach 24 million tonnes.

Bird protection stations near provincial borders in China have been strengthening patrolling and adopting technologies to ensure safe travel for migratory birds as the country poses to establish an extensive work mechanism covering major bird migratory routes across five provinces.
The cross-provincial work mechanism, involving Hunan, Hubei, Jiangxi, Guangdong, and Guangxi, will help strengthen cooperation in fields like information sharing, joint law enforcement, technological cooperation and environmental conservation.
It marks the first attempt of China to increase protection for migratory birds by coordinating efforts from multiple provinces.
The work mechanism will also see stations be set near provincial border to monitor and protect migratory birds, with protective work like patrolling to be launched jointly.
Responsible for monitoring birds traveling along a 40-kilometer route, Nanfeng'ao Migratory Bird Protection Station in central China's Guidong County, Hunan Province, has been strengthening efforts to ensure safe travel for migratory birds entering the province from Jiangxi.
Xiong Fuliang, now in his 60s, has been working as a warden at the protection station since 2014. Patrolling the mountains in search for wounded migratory birds is a part of his job, he said, adding that the migratory season always keeps him busy.
"The wind is strong at night and if it rains, the birds get wet and they tend to clash with the trees and get wounded. If the weather is bad, we will immediately start our patrol to check if there are any wounded birds. If we find them, we will call the forest wardens at once," said Xiong.
As a veteran patroller, Xiong is capable of imitating various bird chirps, a skill that helps him locate wounded birds by stimulating their responses.
He is also able to identify the wounded or trapped birds simply by their chirps. With the techniques, Xiong has saved 13 birds over the recent years.
"The wounded migratory birds have little strength and their chirps sound different. The sounds made by the healthy ones are typically louder. The wounded ones make sounds like 'gu gu gu' and the healthy ones make sounds like 'gua gua gua'," said Xiong.
As mountainous as Nanfeng'ao is, human patrolling is hard to reach every corner of the region and since early this year local wardens have been using drones to improve their work.
"Because the drones are equipped with the night vision devices and the infrared thermal imagers, we use them to detect at night the places frequently visited by the bird hunters, especially the abandoned ones. We also use them to detect the places that are hard to reach. If any suspicious traces are detected, we will send personnel there," said Huang Yongfeng, a forest resource warden of Guidong Forestry Bureau.
Mountainous regions are preferred by migratory birds as airflows going up from the valley bottom help them fly with less efforts. Home to 22 mountains over 1800 meters above the sea level, and with three of them forming a perfect migratory route, Guidong is the staging post for almost all the migratory birds traveling from Inner Mongolia to south China.
"At this time of the year, we see numerous migratory birds flocking to Guidong. The rolling hills and continuous passes on their travel route form 'an aerial channel', and the migratory birds ride the rising airflow and complete their flights easily," said Peng Pengcheng, manager of Nanhua Management Station located in the Qiyunfeng National Forest Park.
Going forward, the four bird protection stations in Guidong and the other five in the wider Chenzhou City will coordinate their efforts to help birds migrate.
"Currently, Chenzhou has nine bird protection stations and four of them are located in Guidong, which are near the border between Hunan and Jiangxi. We will work to connect them and help the birds migrate from one stop to another," said Li Yinfang, staff of the wildlife protection section of Chenzhou Municipal Forestry Bureau.
