The key node of "Asia's First Deep" in Zhuhai welcomes

On the west bank of the Pearl River, on the banks of Huangmao, another "heavy country" in Zhuhai is gradually taking shape. On September 24th, the reporter learned from Zhonghai Fufu Heavy Industry Co., Ltd. that it will be applied to the deep-water pipe rack of the Shenzhen Branch of China Sea Petroleum (China) Co., Ltd. Installation is a key node for the construction of a catheter rack.

The design height of the designed height of Liuhua 11-1 platform is 338.5 meters, which is basically the same as that of the Macau tourist tower. The weight is about 37,000 tons, and the weight of nearly 4 Eiffel Tower is the first self -designed and built 330 -meter deep -water conductor rack in China. It will become the first deep -water conductor frame in Asia and seventh in the world, and become another milestone in the history of the construction of deep water in my country.

The deep -water conductor rack is equivalent to the "foundation" of a fixed maritime oil and gas platform. It is used to support the huge body and huge tonnage of the platform. It is characterized by high, large, heavy, and complicated structure and high quality requirements. The catheter rack is installed in a horizontal posture, that is, keep the lying posture before the water, and then put it in the sea when installation. The center truss buckle is an important structural unit connecting the truss between the centers, and it is also an important part of the entire deep -water tube rack.

The reporter learned at the buckle hanging site that the net weight of the second piece of fastening was 530 tons, 56 meters long, and 27 meters wide. At the crane site, two 750 -ton cranes and two 800 -ton cranes were moved together for more than 200 meters, and then lifted to tens of meters high, and the professionals were handed over to complete high -precision welding.

According to Xu Long, the deputy manager of the Liuhua project of Zhonghai Fufu Heavy Industry Co., Ltd., each point needs to control the deviation within the range of the positive and negative 3 mm in each point, which has greater technical difficulty. To this end, the Catheter Fang Construction Corporation Zhonghai Fufang Organization has made many technical research, breaking through multiple technical difficulties. According to the plan, the conductor rack is expected to meet the basic delivery conditions in March 2024.

As the first 330-meter deep-water pipe rack in design, construction and installation of the country, the capacity limit of domestic construction venues and transportation and installation of ships. In order to increase structural strength and reduce weight, the project will S420 high intensity. The large -scale steel is used in a duct rack, which weighs more than 20,000 tons, setting a new record for similar domestic projects.
