Secondary Active Heave Compensator

Content

The fast responsive active heave compensation systems, built up from proven in practice drive technology and advanced control systems, make sure unexpected and damaging reactions of the load do not occur. By compensating over 90% of the ship movements, based on real time measurements, it is possible to realize unparalleled precision and safe operations at extreme depths. The rotary active heave compensator consists mainly of:

  • Set adjustable axial piston motors as direct winch drive
  • Hydraulic Power Unit (HPU)
  • Accumulator set to re-use energy
  • Motion Reference Unit (MRU)
  • Interfacing piping and cabling
