Passive Heave Compensator

The X-1000 personnel transfer device carries a passive heave compensator (PHC) in its center pole, connected to the upper master link of the rigging. It engages at the start of the lift and then transfers the load to the main rigging, softening the initial take-off from the deck.

The PHC is charged with nitrogen and must be charged before use. Billy Pugh Company supplies the nitrogen filling kit, with regulator, gauges, hoses and adapters in a carrying case, so the charge can be checked and topped up in the field.

  • 5950AA passive heave compensator
  • PHC sling, supplied uncharged: charge before use
