Mobile Early Leak Detection System

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.

MELDS components

  • 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 CH 4 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 CH 4 concentrations)

Key features

  • Designed for easy ROV/AUV integration
  • Modular system with the ability to add any third party sensor such as CO 2 , O 2 , Redox, pH, etc.
  • Detects non-visible hydrocarbon leaks at a very early stage
  • Integrated flow-through system with submersible pump for manipulator directed measurements (i.e. wipe tests on flanges)
  • Data export option for integration into existing data acquisition systems

MELDS Application Example

Easily mobilised on any mid-size ROV, AUV or even a vessel-towed monitoring platform, MELDS is the combination of three different measuring instruments that allows for detection, identification and characterisation of oil and gas related pollution in water.

It provides a fast and cost efficient monitoring method and guarantees a low false alarm rate.

MELDS components

  • A polycyclic aromatic hydrocarbon Kongsberg Maritime Contros HydroC Subsea Fluorometer (PAH) sensor based on the principle of fluorescence for the detection of any oil in water in real time
  • A methane Kongsberg Maritime Contros HydroC Plus (CH) sensor unambiguously detecting gaseous and dissolved CH 4 as well as other hydrocarbons in water
  • A conductivity, temperature and pressure (CTD) probe for the measurement and identification of anomalies in the environmental baseline
