"Face engineering" is the most striking part of ship appearance, which requires high dimensional accuracy and very complicated structure. According to the design requirements of the ship, the enterprise produced a 308,000-ton ship with high quality and precision in about three months, with a length of 59.8m× a width of 32.5m× a height of 23. 1 m and a total weight of 896.7 tons. With the completion of the 308,000 dwt supertanker in CSSC Longxue Shipbuilding Base, Guangdong shipbuilding industry has achieved a new breakthrough, which will fully form the shipbuilding production capacity of Pearl River Mouth Shipbuilding Base, one of the three major shipbuilding bases in China, create a history of designing and building tankers with a deadweight of over 300,000 dwt, create a new record of the largest tanker construction with independent intellectual property rights in China, and establish the position of Pearl River Mouth Shipbuilding Base among the three major shipbuilding bases in China.
