Marine Hydraulic Repair & Maintenance Services
Dolphin Marine Group provides inspection, troubleshooting, repair, overhaul, fabrication, and testing services for marine and offshore hydraulic systems. Our specialised hydraulic team supports lifeboat davits, offshore and pedestal cranes, towing and anchor-handling winches, windlasses, capstans, watertight doors, CPP hydraulic control units, hydraulic power packs, and other hydraulically operated deck equipment.
Our engineers use original manufacturer drawings and hydraulic schematics whenever available to diagnose faults and restore equipment to its specified operating condition. Services can be performed onboard or at our workshop, depending on the equipment and repair requirements.
Equipment We Service
Lifeboat Hydraulic Davit Systems
Inspection, troubleshooting, repair, and testing of lifeboat and rescue-boat davit hydraulic systems, including power packs, pumps, cylinders, control valves, pipes, hoses, and associated components.
Offshore & Pedestal Service Cranes
Hydraulic inspection, maintenance, and repair of offshore cranes, pedestal service cranes, deck cranes, and their power packs, pumps, motors, cylinders, valves, pipes, and hoses.
Towing & Anchor-Handling Winches
Troubleshooting, repair, and overhaul of hydraulic systems for towing and anchor-handling winches, including hydraulic motors, pumps, control valves, brake circuits, cylinders, pipes, and hoses.
Windlasses, Tugger Winches & Capstans
Inspection and repair of hydraulic anchor windlasses, tugger winches, and capstan winches, including their drive systems, control circuits, power packs, and hydraulic components.
Shark Jaws & Elephant Pistons
Inspection, overhaul, seal replacement, pressure testing, and repair of hydraulic cylinders and control systems used for shark jaws and elephant pistons aboard towing and anchor-handling vessels.
Controllable Pitch Propeller Hydraulic Control Units
Inspection, troubleshooting, maintenance, and repair of Controllable Pitch Propeller (CPP) hydraulic control units in accordance with available manufacturer drawings and technical procedures.
Hydraulic Watertight Doors
Inspection and repair of hydraulic actuators, cylinders, valves, pipes, hoses, and power units used to operate hydraulic watertight doors.
Hydraulic Power-Pack Units
Inspection, repair, and workshop testing of marine hydraulic power packs, including pumps, motors, valves, filters, tanks, accumulators, pipes, hoses, and control components.
Integrated Marine Service Support
Dolphin Marine combines marine safety expertise with dedicated hydraulic repair capabilities. Lifeboat and rescue-boat inspections can therefore be coordinated with davit hydraulic-system servicing during the same vessel attendance, helping reduce port time and simplify service coordination.

Frequently Asked Questions
What marine hydraulic systems does Dolphin Marine repair?
Dolphin Marine repairs and maintains a wide range of marine hydraulic systems, including: lifeboat davit hydraulic power packs and cylinders; offshore pedestal and deck cranes; towing, anchor handling, tugger, and capstan winches; hatch cover hydraulic cylinders and power packs; controllable pitch propeller (CPP) hydraulic control units; hydraulic watertight door actuators; and general hydraulic power pack units. Emergency hydraulic response is available at Alexandria, Suez, Dubai (Jebel Ali), and Jeddah.
Can Dolphin Marine service lifeboat davit hydraulics and the lifeboat in the same port visit?
Yes – this is one of Dolphin Marine’s key advantages. Our team can carry out the annual SOLAS lifeboat inspection and the davit hydraulic system service as a combined visit, reducing total port time and eliminating the need to coordinate two separate contractors. Our engineers are trained in both lifeboat inspection procedures and hydraulic system repair, and work from the original davit manufacturer’s schematics.
Do you provide emergency hydraulic repair for vessels in port?
Yes. Dolphin Marine provides emergency hydraulic response for vessels at port across our operating network. For urgent callouts – including hydraulic failures that are preventing cargo operations, blocking a lifeboat from being launched, or causing a PSC detention – our engineers can be on board within hours at Alexandria, Suez, Dubai (Jebel Ali), Fujairah, Jeddah, and Al Khobar. Contact our 24/7 operations line: Egypt +2 01068830785, UAE +971 523740903.
What hydraulic tools and equipment does your team use?
Dolphin Marine’s hydraulic engineers use specialist equipment including a workshop hydraulic power pack test rig with twin pumps for bench testing repaired units, calibrated pressure test gauges and dial indicators, a hydraulic flowmeter for system performance verification, portable on-board test equipment, hydraulic pipe bending and fabrication tools, and high-pressure hose assembly equipment. We work from the original manufacturer’s hydraulic schematics for every repair job.
Can Dolphin Marine fabricate replacement hydraulic pipes and hoses?
Yes. Our hydraulic workshop fabricates replacement hydraulic pipes and hoses to the original specification – matching the correct bore diameter, pressure rating, material, and bend profile. We manufacture hydraulic hose assemblies with BSP, JIC, and ORFS end fittings to suit all major hydraulic system brands aboard commercial vessels. Replacement pipes and hoses can typically be fabricated on the same day for standard sizes.
