Abstract

This application provides an LNG ship-to-ship bunkering control system, method, terminal, and medium. The system includes a control alarm module that monitors the operational status information during ship-to-ship LNG bunkering in real time and analyzes and judges the operational status information to issue warnings; and an emergency cut-off module connected to the control alarm module that monitors the safety status information during ship-to-ship LNG bunkering in real time and selects the corresponding cut-off operation to stop ship-to-ship LNG bunkering based on the safety status information. This system not only meets the safety requirements of converted LNG carriers during ship-to-ship LNG bunkering and provides proactive emergency cut-off of the bunkering process in emergency situations, but also minimizes the need for on-site operation by relevant personnel during the bunkering process. Furthermore, it coordinates with the existing liquid cargo systems of common LNG carriers to achieve the necessary process flow for LNG bunkering, minimizing the addition of equipment and functions and reducing modification costs.
