Active Heave Assist©

Introducing ultra-precise, retrofit-friendly compensation for offshore drilling and floating wind turbine anchor installation, enabling less than 10 cm motion of the drill bit in real-world conditions.

 

 

 

See how it works

Active Heave Assist combines with existing assets to compensate for heave in a range of sea states. The video below shows the system working in real world conditions on a commercial project in the West Pacific. You’ll see a live video feed from the seafloor showing the BHA remaining geostationary despite the vessel’s heave-induced motion at the surface.
