Abstract
The ammonia fuel transport and supply ship includes a hull (1), several independent tanks fixed to the hull (1), liquid cargo collecting pipes (2) and supply collecting pipes (3) connected to each independent tank, and a leakage treatment device installed near the liquid cargo collecting pipes (2) and the supply collecting pipes (3) on each independent tank. The leakage treatment device includes a gas detection station (4) installed near the liquid cargo collecting pipes (2) and the supply collecting pipes (3), and a cleaning tower (5) installed on the hull (1). The cleaning range of the cleaning tower (5) covers the liquid cargo collecting pipes (2) and the supply collecting pipes (3). The ship reduces the risk of poisoning of personnel due to ammonia fuel leakage.
