About this service
Cylinders that hold pressure and move smoothly
Hydraulic cylinders and pistons do the pushing and lifting on a ship: crane booms, davits, hatch and steering gear rams and deck machinery. When one leaks, drifts or moves unevenly, Berth Marine assesses it, dismantles it and repairs it.
Work is done onboard where possible, and in our workshops in Tuzla and Kartal when the cylinder must be removed. See also our hydraulic systems repair for the complete system.
What we do
Scope of service
Fault assessment
Assessment of oil leakage, slow or uneven movement and drift under load.
Dismantling and inspection
Inspection of the rod, barrel, piston and gland for wear, scoring and damage.
Seals and packing
Replacement of worn seals and packing, with spare parts identified through the IMPA system.
Repair or replacement
Repair of worn or damaged components, or replacement where repair is not sensible.
Pressure testing
Function and pressure test after assembly, before the cylinder returns to the vessel.
Onboard removal and refit
Support for removing and refitting the cylinder onboard, coordinated with the ship’s crew.
Good to know
Typical signs of a failing cylinder
Oil leaking at the gland, a scored piston rod, slow or jerky movement, or a load that drifts down when it should hold. Report these early: a small seal repair is far cheaper than a failure during operation.

Common questions
Can a hydraulic cylinder be repaired onboard?
Simple work such as seal replacement can often be done onboard. Where dismantling needs workshop tools, the cylinder is repaired in our Tuzla or Kartal workshops.
What should I send to get a quotation?
Vessel and port, the equipment the cylinder belongs to, maker and model if known, a description of the problem and photos of the leak or damage.
Need this service onboard?
