HEMLIS - Henriksen Multi Lightweight Influence sweep, is a highly customizable and modular MCM sweep solution. Made for safe and efficient operations with unmanned assets. Combining the effects of acoustic signals, air cannons, cables, handling gear, and electric and magnetic power supply. To provide a comprehensive multi-prong attack, made to counter even the most advanced sea mines.

The technology was created in close collaboration with top fleets and operators in the MCM field. Intended to be a self-contained onboard system carried by USV(s). This includes the LARS, control systems, and power supply. Set to trigger mines by simulating the sound waves, magnetic and electrical fields produced by specific vessels beneath the surface of the ocean.

HEMLIS can be configured as a self-contained system with LARS, or by mothership or land based deployments. It is quick to put up on the aft deck of a mothership or dock, as the cables are winched out by our compact special design electrical winches that enables a smooth transfer of the sweep cable to the sea. These cables may then be transferred to dedicated USVs to enable an unmanned operation. The skid towed as a part of the sweep carry the light-weight air cannons and floating elements required to trigger a successful detonation. The system requires a significant amount of power, on small USVs we produce a lightweight powerpack. Which generates the electricity and contains the control system modules and sensors required to operate the sweep. 

The HEMLIS system is modular in size and capabilities. With configurations suitable for any mission requirements. Such as a light-weight straight tail solution, contained and deployed from a small USV. To large scale influence sweeps capable of accurately replicating the exact signatures producted by a specific large cargo ship.
