Recently, an old sea patrol boat that had been out of service for years due to the inability to power air conditioning with DC batteries has found new life thanks to a breakthrough by the Zhenjiang Maritime Safety Administration.
The vessel, known as "Sea Patrol 0824," is a 15-meter FRP (Fiberglass Reinforced Plastic) modified boat. However, because it lacks an AC power system, it couldn't run its air conditioning during operations. In the summer, temperatures inside the cabin often exceeded 40°C, making it nearly impossible for crew members to work. During winter, cold waves and water splashes would hit the cabin, causing the windows to frost over, which created uncomfortable and potentially dangerous conditions. These issues significantly affected both crew comfort and safe navigation.
To solve this problem and give the boat a second chance, maintenance engineers from the Zhenjiang Maritime Safety Bureau took initiative. They collaborated with local manufacturers, conducted extensive research, and developed an innovative solution: a DC inverter booster power supply system. This device allows the boat’s DC batteries to be converted into AC power through an inverter, enabling the use of air conditioning. With this upgrade, the system can provide continuous operation for up to 1.5 hours after being charged for 6 hours.
Thanks to this technological advancement, the long-dormant "Sea Patrol 0824" is now back on duty along the Yangtze River. The success of this project not only revitalized an aging vessel but also saved the unit thousands of dollars in generator costs. Moreover, the technology has broader applications, such as in special environments or for emergency power supply in computer systems. It's a perfect example of how innovation can breathe new life into old equipment while improving efficiency and safety.
