With the continuous growth of the demand for oil and gas resources, the exploration and development has been increasing, the number and scale of fixed platforms in paralic zones are also increasing, and the offshore construction capacity and technology is improving. As one of the key technologies for offshore installation of large-scale platforms, slippage shipment technology is widely used. Based on the wharf environment, the platform structure and weight, this paper comprehensively analyses the allowable tidal window, the longitudinal strength of the ship, the load adjustment capacity, then gives the check results to ensure the safety of the shipment process.

The structural integrity management technology of offshore platform runs through the whole life cycle of the platform, including the stages of planning investment, engineering construction, operation and maintenance, and waste disposal.  The earlier the offshore platform structural integrity management technology is developed, the richer the structural data will be, the more optimized the risk control will be, and the more complete the integrity system will be.  The development of structural integrity management technology in the early construction stage of the platform can provide basic conditions for the management of the platform structure and realize the standardization and intelligence of structural data, which is of great significance for the safety and stability of the platform structure and the later production management and maintenance.
