PASSIVE HEAVE COMPENSATORS
SAFELINK Passive Heave Compensators (PHC) are robust, easy to implement and very easy to use. They offer excellent performance for topside lifts, splash zone crossing & subsea applications, where the dynamic challenges can be reduced significantly by shock absorption, constant tension or overload protection.
All PHC units combine a gas spring (nitrogen) with hydraulic damping (oil) to smoothen out the dynamic effects of waves and vessel motions.
The PHC’s offer excellent performance for topside and subsea applications, where the dynamic challenges can be reduced significantly by shock absorption, constant tension or overload protection.
PHC’s are also available in adaptive execution, where the PHC has the ability to adapt its settings to various environments.
CORE FUNCTIONS:
Shock absorption
Cushions hooks, slings and subsea hardware during splash‑zone transit.
Overload protection
Extends automatically if load exceeds the preset limit—an insurance policy should the AHC system drop out.
Quick lift‑off
High‑pressure retraction of the piston rod lets the crane get clear fast, preventing re‑entry of the payload.
Subsea retrieval
Maintains constant tension while breaking suction piles free and retracts smoothly once the structure releases.
ADDITIONAL FUNCTIONS of ADAPTIVE PHC’s:
Interactive control system
Pre‑load multiple spring/damping “profiles” and switch automatically or on command.
Topside & subsea mode
Swap settings from a deck‑side tablet or via ROV panel—no recovery to deck required.
Resonance avoidance
Actively shifts the lifting system’s natural period so it never syncs with wave period.
Landing‑speed governor
Proves compliance with strict velocity‑limit specifications and widens the operable sea‑state envelope.
Live & recorded data
View loads in real time (ROV) and pull complete motion‑log files afterward to satisfy client QA or feed into installation analysis.
