The chemical engineering industry has seen significant development over the past decade; let’s celebrate the prosperity and strength of modern China. Wishing everyone a happy New Year, and may their families be safe and healthy. By contributing our ideas, we can create a more lively atmosphere for discussion. With you all, Haichuan becomes even better – we invite everyone to participate more actively in the forum discussions. On December 31, 2020, the Industry Promotion Center of the Ministry of Industry and Information Technology organized experts to conduct an evaluation of the “Development of a Deep-Sea Lightweight J-Type Undersea Pipeline Laying System” project, which was developed by Zhenhua Heavy Industry with the assistance of Shanghai Jiao Tong University. The expert group listened to a detailed report from the project team, carefully examined the progress of the project, and after posing questions, unanimously agreed that the project passed the acceptance review. The main objective of this project is to meet the needs for laying short-distance, small-diameter pipelines between deep-sea oil and gas wells, as well as for the installation of underwater facilities. During the project implementation, Zhenhua Heavy Industry developed China’s first engineering prototype of a deep-sea lightweight J-type pipe-laying system on its own, and conducted specialized research on the related core technologies. This pipe-laying system can operate at a maximum pipe-laying depth of 1000 meters, with a maximum static tube string tension of 200 tons. The pipe diameters it can handle range from 4.5 to 12 inches, and it is capable of laying up to two pipe sections at a time. It also has the capability to install underwater terminal PLETs. The expert group believes that this deep-sea lightweight J-type submarine pipeline laying system, with fully independent intellectual property rights, fills the gap in the field of J-type deep-water pipeline laying in China, overcomes key technical barriers, enhances China’s capabilities in deep-sea pipeline laying operations, and plays a positive role in promoting the development of China’s pipeline laying equipment for deep-sea use.
