Offshore and Subsea Hydraulic Cylinders and Actuators

Engineered for Safety and Performance

Passion Engineering’s offshore cylinders are designed and manufactured in exacting detail to safely and reliably perform in aggressive subsea, splash-zone, and marine environments.

Our commitments to our customers, advanced technologies, and continuous improvement yield hydraulic cylinders and systems that secure all your safety, endurance, and performance expectations.

  • Corrosion and wear resistant specialty stainless steel, cobalt, nickel, and other specialty rod cladding systems
  • Cylinders for submerged, splash zone, and exposed marine environments
  • Designs for environmentally sensitive applications
  • Long stroke offshore cylinders with elastic stabilities in compliance with ISO/TS 13725:2016
  • Offshore actuators and systems for hazardous area explosive atmospheres
  • Corrosion, abrasion, and UV resistant paint, coating, plating, and cladding systems
  • Integral end-of-stroke proximity switches and position, pressure, and force transducers
  • Offshore hydraulic cylinders and systems in accordance with the requirements of major marine classification societies and standards organizations
  • Over-sized corrosion resistant bearings
  • Low friction and redundant seal systems
  • Corrosion resisting gimbal, spherical rod end, trunnion, and other mounts

Designed and Built to Keep Your Operations Running

Every custom hydraulic cylinder, power unit, and actuator by Passion Engineering is specifically engineered and constructed to serve the requirements of its application. Understanding the consequences of failure; we build actuators and hydraulic systems for energy exploration and production, offshore wind, aquaculture, wave energy, military, and other offshore projects that reliably serve and endure.
