- Max force 75-4000 t
- Stroke 1.0-8.0 m
- High efficiency (>90%)
- Low weight
- Small footprint
- No external accumulators
- Fast and easy setup
- No oil filling
- Topside design

Adaptive passive heave compensator
Antares is a modern adaptive passive heave compensation unit designed based on lessons learned from decades of experience with subsea heave compensation equipment. It has advanced functionality, low operating risk and relatively low cost.
