Products overview

We have the world’s largest fleet of  rental units ready for immediate dispatch. 
In addition we develop tailor-made units.
 

SHOCK ABSORBERS

KEY BENEFITS
MAIN APPLICATION AREAS
  • Reduces dynamic amplification factor during offshore lift-off and landing.
  • Increases operability of crane in higher waves.
  • Protects crane, rigging and payload from peak loads.
  • Lifts in air
  • Pile hammering
  • Shock absorption
  • Tugger winches
  • Overload protection
  • Shallow water operations
  • MOB boat damper, designed according to Norsok R-002 (if applicable)

STANDARD PHC UNITS

KEY BENEFITS
MAIN APPLICATION AREAS
  • Reduces dynamic amplification factor for lifts in air.
  • Reduces dynamic amplification factor and probability of slack wire for splash zone crossing.
  • Removes resonance during lowering.
  • Reduces subsea landing speed.
  • Improves vertical stability.
  • Protects crane, rigging and payload from peak loads.
  • Lifts in air
  • Off-loading of supply vessels
  • Installation of transition pieces
  • Splash zone crossing
  • Resonance avoidance
  • Subsea landing
  • Subsea retrieval

ADAPTIVE PHC UNITS

Same features as our standard passive heave compensators, but these units adapt to the different lifting phases during operations.
 
PARTICULARLY USEFUL FOR:
  • Deep water operations.
  • Splash zone crossing of demanding payloads.
  • Stroke correction for payloads with high uncertainty in dry or wet weight.
  • Reduction of rigging height through piston locking.
  • Elimination of re-contact during lift-off.
  • Payloads with high buoyancy compared to weight.
  • Logging/verification of forces and movements.

 


WORKING PRINCIPLE OF CRANEMASTER UNITS

Cranemaster is a passive heave compensator system with a double acting hydraulic load absorber. It is is a rugged self-contained hydraulic/pneumatic unit based on gas pressure and hydraulic fluid.
