Leak detectors routinely are specified for subsea installations. In reality, the majority of leaks still are discovered either through routine ROV inspection or observation of surface oil slicks. Leak detection and monitoring of subsea structures are becoming increasingly important because of the need to manage production and control fluids. One of the recently introduced approaches to improve monitoring is a new class of optoelectronic subsea sensors based on fluorescence spectroscopy that provides permanent, realtime monitoring for hydrocarbon production systems.
