What causes most hydraulic failures on marine vessels?

Most marine hydraulic failures trace back to fluid contamination from water, salt and particles, corrosion of fittings and cylinder rods, and seal wear caused by vibration and temperature changes. Good filtration, corrosion-resistant components and regular filter and fluid changes prevent most of these problems.

How often should marine hydraulic systems be serviced?

Service intervals depend on the equipment and how hard it works, but many operators schedule preventative maintenance quarterly or twice a year, with more frequent checks on high-duty equipment such as cranes and launch and recovery systems. PHC builds preventative maintenance plans around your equipment and operating schedule.

Can PHC repair hydraulic components it did not build?

Yes. PHC repairs hydraulic pumps, cylinders and valves from all major brands, including equipment built by other manufacturers. Every repaired valve is tested to its maximum working pressure before it is returned.

Does PHC build custom hydraulic power units for vessels?

Yes. PHC designs and builds custom hydraulic power units sized for the available space, power supply, duty cycle and environment on board, along with the control panels needed to run them.

Does PHC provide on-site service at docks and shipyards?

Yes. PHC field service technicians can install, repair and maintain pumps, cylinders, gauges, hydraulic power units and test systems on site, so equipment gets back in service with as little interruption as possible.

Marine Hydraulics & Pneumatics | Pneumatic and Hydraulic

Hydraulic & Pneumatic Solutions for Marine & Shipping

Pneumatic and Hydraulic Company (PHC) supplies, builds and repairs the hydraulic and pneumatic equipment that keeps vessels, offshore platforms and shipyards working. From hydraulic power units and cylinders for deck machinery to pressure test equipment and breathing air systems, PHC supports marine operators from our Gulf Coast locations in Texas and Louisiana, with support available 24/7/365.

Hydraulics Built for Harsh Marine Environments

Salt spray, constant vibration, temperature swings and tight machinery spaces put marine hydraulic systems under more stress than most land-based equipment. Contaminated fluid, corroded fittings and worn seals are the most common reasons cranes, winches, steering gear and launch and recovery systems (LARS) go down.

PHC helps marine operators specify components that hold up offshore, including stainless instrumentation fittings, sealed cylinders, corrosion-resistant valves and high-efficiency filtration from brands such as Schroeder Industries and Tylok. When a standard component will not fit the space or the duty cycle, our engineers design custom hydraulic power units and hydraulic control panels around the vessel’s actual layout and operating demands.

Repair, Testing and Field Service That Keeps Vessels Moving

Every day a vessel waits at the dock for a part or a repair costs money. PHC rebuilds hydraulic pumps, cylinders and valves from all major brands, and every repaired valve is tested to its maximum working pressure before it ships.

Our field service technicians can come to the dock, shipyard or facility to install, troubleshoot and maintain hydraulic power units and test equipment, and preventative maintenance plans help catch filter, fluid and seal problems before they turn into failures at sea. For hose and line certification, PHC builds hose test rigs and portable pressure test carts sized for shipboard and offshore use.
