Project background

The shipyard was established in 1999 and is a wholly-owned subsidiary of China State Shipbuilding Corporation. The factory covers an area of 5 million square meters. It is one of the most large-scale, modern, professional and influential shipbuilding enterprises, and the "No. 1 brand" of China's ship export 

■ Facing problems:

As a typical precision discrete manufacturing enterprise, the shipyard has scattered production processes, complex processes, high energy consumption, and relatively independent production links More, there is a relatively large space for energy efficiency optimization.

Due to the large number of water, electricity, energy and other equipment, which are highly dependent on manual monitoring and operation and maintenance, there is a large demand for operation and maintenance personnel; In order to ensure the accuracy of data, it is necessary to set up monitoring and maintenance personnel at each gas station, which makes management difficult and economically costly; the failure rate of power energy equipment is high.

■ Solution:

Full energy system monitoring. Based on the organic combination of Internet of Things, 5G and wired connections, advanced industrial interconnection middleware data Communication Systems. Realize energy point monitoring and information remote transmission covering the whole plant. Build a web-based configuration with strong interactive functions to support rapid deployment and highly customized functions.

Device reverse control. For the site energy supply system of a large-scale factory area, it is transformed based on traditional manual valves and PLC systems. Model the site equipment according to the data points to realize remote equipment control, such as valve switch, pressure setting, PID setting and other operations.  

Energy efficiency analysis and calculation. Based on multi-level measurement and multi-source data monitoring system, statistical analysis by process and department Energy consumption, promote and deepen the energy consumption evaluation and the establishment of industrial process energy consumption standards.

Comprehensive energy security management. Build an intelligent report system to replace traditional energy site reports. Improve management efficiency and simplify work such as fund collection and data analysis. Through the system-defined alarm and push, combined with the inspection system, the response time is shortened.

■ Project value:

The unit energy consumption is reduced by 8%. The whole system guarantees the energy supply of shipbuilding with complex crafts to monitor, counter-control and alarm Improve the ability of business execution, use data analysis to troubleshoot energy efficiency problems, and reduce unit energy consumption in two ways.  

The number of annual failures is reduced by 50%. Reduce the frequency of equipment failures through equipment renewal, efficient control response, and actual operation and maintenance efficiency improvement.  

Operation and maintenance personnel decreased by 40%. Based on the remote control of site equipment and cloud monitoring, the original 4 site distribution is changed to 1 Site master operation and maintenance.
