Safety first. Prevention first: Let’s give praise and support to the achievements made in China’s chemical industry technology and equipment. **********************【Ten Years of Rapid Development in Chemical Industry Equipment】A continuously updated summary post is available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Industry Forum) *****************On August 12, 2024, the largest and most capable international offshore oil and gas platform built in China – the Marjan oil and gas processing platform in Saudi Arabia – was completed and delivered in Qingdao, Shandong Province. Built by Offshore Oil Engineering (Qingdao) Co., Ltd., the platform will, after 34 months of construction, be shipped on a large transport vessel at the end of this month to areas 6,400 nautical miles away for installation, in order to enhance production at the Mazar oil field on the eastern coast of Saudi Arabia. The Mazan platform, which has been completed and delivered this time, is an 8-leg offshore oil and gas gathering platform. Its main function is to collect the oil and gas extracted from the sea and transport them to land for processing; it is capable of transporting 24 million tons of crude oil per year (the crude oil production of China’s Shengli Oilfield in 2023 was 23.4512 million tons), as well as 7.4 billion cubic meters of associated gas. It is considered one of the offshore platforms with the strongest oil gathering capacity in the world. This completed \"giant\" weighs over 17,200 tons, which is equivalent to the total weight of 17,000 cars; its height exceeds that of 24 floors. The area of its decks is about equivalent to that of 15 basketball courts. The total length of the cables used is enough to circle Beijing’s Fifth Ring Road twice and a half, and the size of the pipelines as well as their complexity set records for platforms of this type. Construction of this platform began in October 2021. During the build phase, the project team overcame challenges such as the COVID-19 pandemic, delays in equipment delivery, and technical gaps; they developed an intelligent management platform on their own, introduced an innovative \"integrated + visual\" construction approach, and made extensive use of advanced technologies such as automated welding of composite materials and phased array ultrasonic testing. As a result, the construction efficiency, quality compliance rate, and safety performance all reached world-class levels.
