AI Technical Summary
The sealed empty compartments of existing ammonia-fueled ships are prone to safety hazards due to the entry of humid air during regular inspections, and the risk of ammonia leakage is difficult to effectively monitor and handle.
Nitrogen generators and drying units are installed in ammonia-fueled dual-ear tank vessels to dry the isolated compartments through dry air pipelines. Dew point sensors, ammonia concentration sensors, and water spray systems are also provided to enable immediate alarm and handling of inerting replacement and ammonia leaks.
It effectively maintains the dry state of the isolated chamber, prevents humid air from entering, reduces the risk of ammonia leakage, ensures operational safety, and promptly handles potential leaks to reduce safety hazards.
