Leak Detectors

Benestad’s Hydrocarbon Leak Detector (HLD) limits the environmental impact and cost of incidents by enabling fast and efficient implementation of corrective measures. The detector continuously monitors the environment and helps detect leakages from subsea structures. It also makes sure that operators comply with current and future environmental requirements.

The HLD is a capacitive based sensor that has been in subsea service since the mid-nineties. It comes in both ROV-retrievable and non-retrievable versions and is relatively small and easy to fit onto most subsea structures. The electrical interface options are 4-20mA or CAN443.

Our Water Leak Detector (WLD) is designed to detect water ingress into enclosures filled with dielectric oil. The typical application is subsea control modules and transformers. The WLD can be applied to all leakage-exposed systems as long as the dielectric constants of the two involved mediums are sufficiently different.

The WLD is a capacitive based sensor with long record of subsea usage. It comes in 1-level and 3-level version both with 4-20 mA electrical interface.
