A Marine Forecasting System Used for Outer Sea Immersed Tube Guarantee

Abstract

The invention discloses a marine forecasting system for open-sea immersed tube protection. The system is composed of a real-time marine environment observing system, a tide and tidal current forecasting system, a weather forecasting system, a sea wave forecasting system, an ocean current forecasting system and a nowcasting system. The marine forecasting system being integrated with real-time marine environment observing, tide and tidal current forecasting, weather forecasting, sea wave forecasting, ocean current forecasting, and nowcasting is capable of evaluating and estimating meteorologicalmarine environmental risks of open-sea immersed tubes comprehensively; with consideration of the bearing capacity of open-sea immersed tube construction to various environmental risks, forecasting products of all environmental elements are manufactured and the period of time of meeting construction conditions by all elements simultaneously is selected to manufacture a window forecasting product,so that the construction time plan is formulated conveniently and accurately for open-sea immersed tube construction.

Description

technical field [0001] The invention relates to the field of ocean engineering, in particular to an ocean forecasting system for offshore immersed tube support. Background technique [0002] Existing meteorological and oceanographic forecasts have short timeliness: usually only for the next 3 days; few elements: only wind force and direction, significant wave height of waves, average wave direction, surface sea temperature, and ocean currents; low time resolution: usually 24 hours, only forecasting of daily Average condition; low spatial resolution: only large-area forecast, usually sea area forecast; low forecast accuracy. In the face of more detailed project immersed tube construction, the construction window needs to be selected one month in advance, and the construction conditions need to be judged based on the maximum wave height, 1 / 10 wave height and corresponding cycle, the current flow direction of each layer, and the seawater density of each layer. Accurate forecas...
