Real-time forecasting system for ocean short-term circulation

Abstract

The invention discloses a real-time forecasting system for ocean short-term circulation. The system comprises a marine environment real-time detection subsystem and a forecasting subsystem. Local short-term change data of meteorological and marine environment parameters of an operation area can be monitored in real time; and the environmental risks of the marine operation under the circulating current are estimated through comprehensive evaluation including tidal power flow forecasting, weather forecasting, sea wave forecasting, ocean current forecasting and proximity forecasting units, and the time periods of all elements meeting the construction conditions at the same time are selected, so that the marine operation can make an operation time plan more conveniently and accurately.

Description

technical field [0001] The invention relates to the technical field of ocean engineering, in particular to a real-time forecast system for short-term ocean circulation. Background technique [0002] Ocean circulation is the study of wind-induced ocean currents and density currents produced by uneven density distribution, generation and distribution of current swirls in ocean circulation, westward strengthening of ocean circulation, bending and variation of ocean currents, current structure in near-equatorial regions, Antarctic circumpolar current, oceanic thermohaline circulation, deep-sea circulation and its relationship with the maincline, the relationship between the divergent and convergent movement of sea water and the up-down current and Langmuir circulation, mesoscale eddies and their energy conversion, ice drift and other special Flow phenomena, the response of the ocean to wind stress, etc., and the circulation of the near-shore sea area, etc.; [0003] The influen...

Problems solved by technology

[0005] The second is helicopter landing. The platform is located above the sea, and it is difficult to transport conventional supplies, personnel and equipment. As an air transportation method, helicopters are very suitable for transportation on the platform.

In the process of personnel lifting, platform movement will pose a serious threat to the safety of equipment and even the life safety of staff

[0008] The fifth is collaborative operation between platforms. For offshore platforms, when the oil production platform has stored a certain amount of crude oil, it needs to transport this part of the oil. This requires the use of shuttle tankers. When the platform and the shuttle tanker carry out oil transportation operations, Since the commonly used method of oil transportation is the use of suspension pipelines, the relative position of the two is required to be less than a certain value, otherwise the operation will not be carried out normally and even the pipeline will be torn, threatening the safety of the platform and the shuttle tanker

For the float-over installation operation, API gives the limitation of the ultimate tension and safety factor of the mooring line of the barge. When the waves are large, the force of the mooring line exceeds the specification requirements, which will affect the installation process and even threaten the safety of the platform and barge

For the floating crane method, when the floating crane is operating in large waves, it will be difficult to align the installation position and affect the normal installation platform. When the movement range is too large, it may even lead to safety accidents
