We delevoped a complete technology system which the whole or part is above the world-leading level by conducting the engineering, construction and installation of 30,000 tons ultra-large offshore facilities. As EPCI contractor, we delivered the Liwan 3-1 central platform which jackt is 32,000 Tons  and float-over installation weight is 32,000 Tons for reaching the world-leading level.

We developed key modular construction technologies for cryogenic insulation, ultra-low temperature steel welding, large-area application of fire retardant paint, module outfitting maintenance system, non-slide area construction, transportation and loadout of modules using SPMTs and fully automated manufacturing equipment with independent intellectual property rights which products portfolio covering central pipe galleries and all kinds of process modules. We successfully delivered any modular construction projects with domestic and international influence, such as the construction of modules for Australian Nickel Mine project, and Canadian LNG project.
