While fiber optic sensors offer advantages for leak detection in subsea pipelines, they also have limitations. A primary limitation is their sensitivity to environmental conditions. Changes in temperature and pressure, which are common in subsea environments, can affect the fiber optic signal and create false alarms or mask leak signatures. Distinguishing between environmental changes and actual leak events requires sophisticated signal processing and compensation techniques. Another limitation is the cost of installation and maintenance. Deploying fiber optic sensors along the entire length of a subsea pipeline can be expensive, especially in deepwater environmen....
