Windlass- Mooring Winches

Windlasses and mooring winches are extremely critical equipment that directly affects the safety and operation of the vessel and its crew. Winches are subject to heavy loads during operation, which, together with corrosion and sometimes improper operation, may lead to wear, damages, and even accidents.

The above is why we perform complete windlass and mooring winch maintenance services, including:

  • Jack up test and reporting
  • Overhauling of brakes, renewal of bands, and maintenance of brake mechanism
  • Complete overhauling and inspection of windlass onboard and at the workshop, including drums, shafts, and couplings
  • Repair of windlass shafts, alignment control, rebuilding of bearing journals by laser cladding or SAW, machining and fabrication of new shafts
  • We fabricate bushes of normal type or split type. Additionally, we keep G5, G7, and G12 bronze in stock to supply the appropriate material for the bushes.
  • Hydraulic motor overhauling and spare parts supply
  • Compete for windlass assembly re chocking and alignment
  • Gypsy wheel repairs, including welding and machining
  • Windlass drums repairs by rebuilding in the way of brake landing surfaces and boring of bush housings.
  • Repair of couplings and clutches
  • Blasting and coating of all parts
  • Operating test and reporting

At Injegov, we have experience in windlasses and winches of all makes, including Rolls Royce, Hatlapa, Aker Pusnes, MacGregor, and others.

Hydraulic Cylinders

Hydraulic cylinders are used in various applications. We find them on hatch covers, different cranes, including lifeboat and cargo handling, lifting jacks, and even steering gear.
Hydraulic cylinders during operation may suffer from decreased pressure due to oil leakages. Wear of the seals, corrosion and impact may damage the chrome-plated piston rod running surface and lead to failure.

At Injegov, we perform the following services on Hydraulic cylinders:


  • Complete overhauling on board and at the workshop, inspection, and pressure test
  • Supply of seals, O-rings, spherical bearings, high-pressure hoses, and spares
  • Fabrication of piston crowns, nuts, and rods.
  • Recondition the piston rod by chrome plating or laser cladding, giving a new life to the piston rod with improved characteristics compared to chrome plating.
  • Fabrication of pins
  • Boring of pin housing brackets in situ

Pumps are critical equipment for the operation and safety both on ships and land-based industrial facilities. Pumps can be used to pump ballast water, specialized cargo like diesel or heavy fuel, lubricating oil for engines and various equipment, firefighting, and various other applications.

Depending on the application, pumps used are centrifugal single or multistage, screw type, piston, vacuum, geared, and many others
Pumps during their operation may suffer from corrosion and mechanical wear on their main comps such as shafts, impellers, bushes, mechanical seals, gears, and housings.
Our technical team, combined with our workshop facilities, can provide complete service solutions for all pump types.

Our pump repair services include:

  • Overhauling, inspection, and testing of pumps on-site and at the workshop
  • Fabrication of mouth rings, bushes, and shafts on our modern machine shop.
  • Recondition of impellers with stainless steel, Inconel, or other appropriate special coatings by laser cladding
  • Recondition of pump casings by machining, installation of sleeves, and boring in situ and at the workshop
  • Special Coating of pump components by laser cladding
  • Supply of mechanical seals and bearings
  • Alignment

As a one-stop-shop for your pump maintenance requirements, we also undertake the primary pump mover and components such as diesel engines, steam turbines, and COPT governors.


Compressors can be found in many applications onboard vessels, powerplants, oil refineries, and various other industries. Depending on the application, different compressor types include rotary compressors, reciprocating compressors, axial compressors, screw compressors, and centrifugal compressors.
Compressors are critical for the supply of compressed air, starting air on various energy and marine applications, refrigeration applications, and ammonia and gas on oil refineries and chemical plants.

Injegov, with decades of experience in compressor maintenance, can provide the following compressor maintenance services:

  • Overhauling, inspection, and service of all types of compressors on-site and at the workshop
  • Reciprocating compressor parts supply /fabrication
  • Recondition of compressor components by laser cladding
  • Powerplant compressor maintenance packages
  • Maintenance on oil compressors for marine and oil and gas applications
  • Compressor Maintenace packages during oil refinery shut down maintenance periods
Safety Valves & PV Valves

Safety and pressure vacuum valves are critical for the safety and operation of boilers, tanks, and pipe networks onboard vessels, power plants, chemical plants, and oil refineries. Continuous testing and proper maintenance ensure correct operation, safety, and compliance with local and international regulations and standards.

At Injegov, we have broad experience in the repairs of safety and P/V valves. We operate mobile test benches to check and calibrate safety and pressure vacuum valves, and we have high expertise in total plant maintenance projects.

By utilizing our workshop machinery, skilled technicians, and testing equipment, we can perform the following services:

  • Overhauling of safety or PV valve

Contact us for our total valve maintenance packages if you are a ship manager, power plant, or oil refinery operator.

Coolers & Heat Exchangers

Heat exchangers can be found onboard vessels at power plants, oil refineries, chemical plants, and various industrial facilities where heating or cooling applications are necessary.

According to their application, there can be air coolers, oil coolers, water coolers, condensers, evaporators, refrigeration coolers, and many more.

According to their construction, there can be tube-type coolers and plate-type.

Typical damages occurred to coolers  heat exchangers can be:

  • Blocking of cooler tubes from water minerals
