Tension Control
Cranemaster® ensures consistent tension control, safeguarding equipment and enhancing operational precision in challenging offshore and marine environments.
Cranemaster® Passive Heave Compensators
Cranemaster® Passive Heave Compensators enhance offshore lifting by reducing dynamic forces, protecting equipment, and improving safety. These self-contained units expand weather windows and ensure precise load positioning, with capacities up to 1600 tons and stroke lengths up to 5 meters.

Key Operations
Cranemaster® technology provides advanced tension management to address the complexities of offshore and marine lifting, offering reliability and safety across diverse applications:
Constant Tension in Dynamic Conditions: Maintain stable wire tension during operations, compensating for vessel heave and preventing slack or snap loads.
Controlled Lift-Off Dynamics: Reduce dynamic amplification factors (DAF) for smooth and safe lift-off procedures, even in rough seas.
Splash Zone Stability: Minimise risks of slack slings when lowering heavy loads through the splash zone, ensuring precise handling.
Subsea Operations: Ensure consistent tension for safe lowering, landing, or recovery of subsea structures, protecting cranes and rigging from excessive forces.
Cutting and Sawing Support: Achieve continuous tension during cutting operations, improving safety and operational efficiency.
Cranemaster’s tailored solutions deliver unparalleled tension control, helping offshore and marine projects achieve operational success while protecting valuable assets in demanding conditions.
