Traditional LNG engineering construction mainly relies on site construction, with long construction duration, high cost, low quality controllability, high safety risks and low reuse rate.The promotion and application of LNG modular fabrication can reduce the influence and restriction by weather, resources and other factors.A LNG project extends the design concept from conventional design to modular fabrication, and provides a new construction mode of skid-mounted station and modular plant from the aspect of efficiency, safety, quality, procurement, transportation and storage.On the one hand, this model gives full play to the safety, quality, duration and cost advantages of modular fabrication,on the other hand, it makes most of the design issues solved in the construction plant.Modular fabrication is the extension and updating of conventional design.Without process reengineering, method updating, establishment and application of standard component library and knowledge base of designers, it is difficult to realize large-scale factory prefabrication.Without management innovation and refinement of managers, it is difficult to realize the leap-forward development of modular fabrication.The successful application of modularization in LNG engineering construction opens up a new path for LNG engineering construction.
