“…To address the above problems, the critical working regions, such as offshore platforms and vessels, should be monitored for subsea gas leaks so that related operators can raise the corresponding alarm at an early stage and thereby make timely emergency and prevention measures. Past decades have witnessed the development of subsea gas leak monitoring approaches and technologies [13][14][15][16][17][18][19][20][21][22][23]. These works can be classified into two categories: software-based internal methods and hardware-based external methods [14,22].…”

“…These works can be classified into two categories: software-based internal methods and hardware-based external methods [14,22]. Among them, the internal method mainly monitors related gas flow parameters, such as flow mass or volume, negative pressure waves, and gas flow rate, and then judges whether a subsea gas leak is occurring [14,19,22]. By contrast, the external method needs external sensors such as hydrophones [13,19], optoelectronic sensors [17,18], fiber-optic cables [15,16,23], and optical cameras [14,20,21,24] to realize the subsea gas leak monitoring.…”

“…Günümüzde sualtı ortamında pasif akustik dinleme sualtı boru hatlarındaki sızıntıların algılanması/konumlandırılması [1,2], gemilerin algılanması [3,4], deniz canlılarının takip edilmesi [5,6] gibi birçok uygulamada kullanılmaktadır. Zaten kurulu ve kullanılmakta olan bu pasif akustik sistemlerle algılanabilecek başka bir akustik kaynak ise hava taşıtlarıdır.…”
