SYSTEM AND METHOD FOR DETECTION OF HYDROCARBON LEAKAGE FROM AN UNDERWATER PIPELINE IN A BODY OF WATER AND HYDROCARBON EXTRACTION UNIT

摘要

A leakage detection system (9) for detecting hydrocarbon leakage from an underwater pipeline (8) in a body of water (5) having a sensor (18) configured to acquire signals related to the temperature of a liquid inside a chamber (19) that is not watertight and which, in use, is full of water and extends along a portion of underwater pipeline (8) susceptible to leakage, and a control unit (22), which is connected to the sensor (18) and is configured to control if the temperature of the liquid in the chamber (19) is within an expected range and emit a leakage signal when the temperature of the liquid in the chamber (19) is outside the expected range.
