Nippon Steel&Sumitomo Metal Corporation (NSSMC) was the world's best steel manufacturer in its early days. Especially with the development of ocean development activities from shallow water to deep water, the environmental conditions faced by offshore platforms have become more stringent, which has put forward higher and more demanding requirements for the construction of offshore platform legs. The toothed strip plate and semi-circular plate serve as load-bearing components in the pile legs, and the pile legs, as the main load-bearing units of the platform structure, place high demands on their mechanical performance. The material of the pile legs, especially the toothed strip plate, is ultra-high strength steel, is difficult to weld and install. The pile legs and lifting system are the most important parts of the self elevating platform, which bear great loads, and their service life directly affects the service life of the platform. They must be high-quality products.
