Active Heave Compensators
Active heave compensators are designed for the safe landing to, and lift from, the sea bed during high seas. AXTech delivers a range of inline AHCs which reduce the vertical movement to a minimum in sea conditions of up to Hs 5.
Our AHCs are built as free-standing inline systems based on one or several hydraulic cylinders (linear system).
The AHC´s can also be used as one-impact shock absorbers simply by turning a switch in the control system.
Our shock absorbers are passive systems based on the same principle as the AHC, i.e. a hydraulic cylinder working against an accumulator and a number of gas cylinders. PHC provides a simple and useful tensioning system, protecting the equipment from sudden impact.
