Professional Hydraulic Power Unit (HPU) Overhaul & Maintenance for Ships in Mombasa
A ship's hydraulic power unit (HPU) serves as the central heartbeat for numerous vital shipboard operations, supplying pressurized fluid to deck machinery, cargo systems, steering gear, and engine room auxiliaries. When a ship operates in demanding maritime environments, continuous high-pressure cycles put immense thermal and mechanical stress on the HPU pump stations, valves, and oil reservoirs. When a ship's main hydraulic power unit suffers catastrophic pressure loss, internal pump failure, or severe oil contamination during a port call at the Port of Mombasa, rapid and expert technical intervention is mandatory to prevent costly ship downtime and schedule delays. Since 2011, Mombasa Ship Services has coordinated specialized hydraulic power unit (HPU) overhaul and maintenance solutions specifically tailored for international commercial shipping fleets visiting East Africa.
We connect shipowners, technical superintendents, and chief engineers with certified marine hydraulic engineers in Kenya experienced with high-pressure fluid systems across major shipboard manufacturers. Whether your ship requires an emergency HPU pump replacement, complete oil reservoir cleaning, or scheduled system maintenance, our 24/7 technical coordination desk ensures rapid shipboard attendance and reliable operational restoration.
Comprehensive Ship HPU Restoration & Maintenance Scope
Maintaining a ship's hydraulic power unit requires meticulous mechanical precision and strict cleanliness standards to protect delicate control components. Our specialized service scope covers:
Axial Piston Pump & Motor Overhauls: Stripping heavy-duty swashplate pumps on the ship's HPU, inspecting internal pistons and valve plates for scoring, and restoring volumetric efficiency.
Oil Reservoir Cleaning & Sludge Removal: Draining contaminated hydraulic oil from the ship's HPU tank, removing accumulated sludge, scale, and moisture deposits, and thoroughly flushing internal surfaces.
Filtration Unit & Heat Exchanger Servicing: Replacing clogged return and pressure filter elements, servicing oil-to-water cooling heat exchangers, and repairing bypass valves on the ship's hydraulic system.
Manifold Block & Control Valve Rebuilding: Dismantling proportional and directional control valves on the ship's HPU, replacing internal O-rings, and recalibrating system pressure relief valves.
Accumulator Testing & Nitrogen Charging: Inspecting bladder and piston-type accumulators on the ship's HPU, verifying nitrogen gas pre-charge pressures, and renewing faulty gas valves.

Servicing a ship's hydraulic power unit requires specialized technical equipment and rigorous contamination control protocols. Mombasa Ship Services guarantees operational reliability through:
Decade-Plus Regional Experience (Est. 2011): 15+ years of maritime coordination history in Mombasa ensures seamless ship agency integration, fast heavy-lift transport, and expert technical execution for every ship calling at the port.
Specialized Diagnostic Tooling: Our technicians utilize calibrated pressure gauges, digital flow meters, particle counters, and portable filtration units to test and verify the ship's HPU performance.
Class-Ready Compliance Documentation: Detailed pressure test charts, oil analysis logs, and English service reports are supplied immediately for your ship's machinery history files and Class surveyors.
Service Implementation Workflow
Step 1: Defect Reporting: Report HPU pressure fluctuations, pump overheating, or oil contamination on your ship to our 24/7 technical operations desk.
Step 2: Onboard Inspection & Isolation: Certified hydraulic engineers board the ship to inspect the power pack, test system pressures, and safely isolate circuits before starting work.
Step 3: Overhaul, Flushing & Testing: Components are rebuilt, reservoirs are cleaned, oil is filtered, and the ship's HPU is tested under full operational load before sailing.
