The Mobile Early Leak Detection System (MELDS) is a unique system for detection, localisation and qualification of subsea oil and gas leakages at a very early stage. It combines three completely
independent methods for direct and indirect detection of hydrocarbons and associated anomalies. Mounted on an ROV/AUV or towed behind a vessel, MELDS allows for a wide area coverage in a short
timespan and investigations at specific locations of interest.
- A polycyclic aromatic hydrocarbon Kongsberg Maritime Contros HydroC Subsea Fluorometer (PAH) sensor based on the principle of fluorescence for the direct detection of oil in water in real time
- A highly sensitive Kongsberg Maritime Contros HydroC Plus (CH) sensor, unambiguously detecting gaseous and dissolved CH4 in water as well as other hydrocarbons
- A conductivity, temperature and pressure (CTD) sensor suite for the measurement of associated anomalies and for establishing an environmental baseline for any further investigations (such as the calculation
of CH4 concentrations)
