Blue “Guardian”: The environmental mission of ocean dumping online monitoring equipment

In order to supervise the entire process of ocean dumping activities, the former State Oceanic Administration issued "Ocean DumpingRecorder Management Regulations" requires ships engaged in ocean dumping operations in waters under my country's jurisdiction to install online ocean dumping monitoring equipment. For ships that carry out ocean dumping in ocean dumping areas approved by the State Council, the sea area branch shall be responsible for organizing and installing online ocean dumping monitoring equipment.

For ships that carry out ocean dumping in temporary ocean dumping areas, the construction unit shall install online ocean dumping monitoring equipment on its own in accordance with relevant standards and must register with the relevant sea area branch. The State Oceanic Administration has organized various maritime branches to establish a real-time dynamic monitoring system for ocean dumping activities to realize the sharing of ocean dumping supervision information between marine administrative departments and marine surveillance agencies at all levels.

However, the existing online monitoring equipment for ocean dumping has the following problems in practical application:

1. The use of GPS positioning does not comply with The current development trend of independent control;

2. Use water pressure sensors to measure draft. The sensors need to be installed on the bottom of the ship, which is inconvenient to install and maintain;

3. The collected data cannot be reported in real time outside the coverage of the mobile network;

4. The system platform is not open, and relevant parties in the dumping activity cannot see the reported data;

5. There are differences in the data collected and reported by various manufacturers, and some equipment does not have draft depth and valve switching status data;

6. Different equipment monitoring data reporting mechanisms and The frequency is different, some equipment only reports data before and after entering the port and dumping, and some equipment reports data regularly;

7. Multiple monitoring platforms are distributed in different units, lacking a unified system platform and standards.

Marine dumping online monitoring equipment is mainly used to supervise ship dumping behavior. The main monitoring indicators are the position, draft and mud door information of the ship. Data communicationThe signal volume is small, and the use of Beidou short message communication can effectively solve the problem of insufficient real-time communication.

The functional performance proposed in the technical requirements and test methods for marine dumping online monitoring equipment are mainly based on technologies including Beidou short message communication, Beidou positioning, and water pressure sensors to collect pressure data and convert ship draft. Depth and other technologies, each major technology can be implemented after actual testing and verification or citing relevant standards.

The technical requirements and test methods for online monitoring equipment for marine dumping are proposed, which can standardize the development of relevant online monitoring equipment for marine dumping by various manufacturers and provide a basis for the inspection of products by industry authorities. It is conducive to the overall development of the market, more conducive to standardizing the dumping behavior of ships in dumping operations, and can play a significant role in protecting the marine environment.
