Solution details
- The scientific and technological field to which the project belongs
This project belongs to the field of marine technology. - Main content of the project
Wenzhou Oufei silting type high-mud reclamation and breeding sea (Oufei Project) is located in the shoal between the Oujiang River and the Feiyun River in Zhejiang Province, with a reclamation area of 8853.7184km2, making it currently the largest single reclamation project in my country. This project has established a dynamic monitoring system and a comprehensive early warning support system. The dynamic monitoring system grasps the cumulative effect of construction on the marine environment through monitoring sea use activities and tracking and monitoring resources and environment, regulates sea use, ensures maximum sea use efficiency, and provides scientific basis for the marine department to implement supervision; The comprehensive early warning and support system adopts a combination of numerical and empirical forecasting, and provides refined and customized services at three levels and four categories based on an information platform to ensure construction safety. The system has created a new service model to provide early warning and support for major offshore projects. - Project characteristics
(1) Improve the dynamic monitoring system
Establish a dynamic monitoring system for sea area use consisting of video surveillance, on-site monitoring, satellite remote sensing, and aerial photography in the Oufei project area; establish a tracking and monitoring system for marine resources and environmental impacts based on 7 hydrology, 20 water quality, 15 sediments, 15 bioecology, and 12 fishery resources. Based on the foundation, special monitoring is carried out based on the project construction conditions, and dynamically adjusted with the progress of the project.
(2) Leading dynamic monitoring methods
A combination of remote sensing, ground measurement, and construction ship positioning measurement is used to control the sea range, and remote sensing technology is used to make up for the shortcomings of long time spent on ground measurement and difficulty in measuring structures without flowing out of the water; real-time video surveillance has timely information and saves labor costs and other advantages.
(3) Advanced forecast information technology
The numerical simulation technology of complex hydrodynamic environment is used to fill the gap in refined forecast in the sea area of the Oufei Project; advanced technologies such as interpretation of numerical prediction systems and human-computer interactive correction are used to achieve the full integration of numerical prediction and empirical prediction, and the accuracy of traditional forecasts is transformed. Depends on issues such as the individual level of forecasters and the single form of product expression; the frequency of forecast products reaches the level of hours or even minutes, the forecast area is refined to tens of meters, and the forecast accuracy reaches more than 85%; Using server virtualization and dynamic task scheduling technology, it realizes rapid and automated processing of massive measured data and numerical forecast products, provides data support for the production of comprehensive forecast products, and improves forecast production efficiency by at least 40%.
(4) Innovation in forecast support service models
The comprehensive marine environmental security system has achieved "six modernizations" services that are refined, customized, technological, standardized, business-oriented and personalized. Closely follow the progress of the project, fully integrate numerical forecast and empirical forecast, transform the traditional forecast support model, establish a user feedback mechanism, and dynamically adjust the support content: in order to reasonably arrange construction plans and ship dispatch, regional weather forecasts for the next 120 hours are needed; Secondly, in order to ensure construction safety, it is necessary to conduct refined hourly forecasts of wind, waves, currents and tide levels at key construction points. In addition, early warnings of major marine disasters are necessary to avoid casualties and economic losses. Based on the above needs, product design was carried out and marine environment forecast services in three levels and four categories were customized: (1) marine forecast services in the sea area near the Oufei Project;(2) construction ship route safety forecast services;(3) construction area Key point ocean forecast services;(4) storm surge and wave warning services during disasters. It has created a new service method for comprehensive support for major offshore projects, and has gradually promoted it to Wenzhou and Ruian Ocean and Fisheries Bureau, etc., playing a demonstration role in the protection of related sea-related projects. - Application and promotion
The monitoring data of the Oufei Project is used in the compilation of the Marine Environment Bulletin of the East China Sea Region, Zhejiang Province, and Wenzhou City. The observation data has been incorporated into the operational observation network of the Oceanic Administration to provide basic data for disaster prevention and reduction in Zhejiang Province and the entire East China Sea Region; monitoring technology has been applied in the construction of Yangshan Port diversion embankments, Yangtze River Tunnel Bridge and other projects; forecasting and information technology has been used many times in the construction of Yangtze River Tunnel and Bridge, Nanhui siltation Promotion and other projects; The refined forecast support service model has been effectively applied in major projects such as Qinshan Nuclear Power and Sanmen Nuclear Power.
