Propulsion and Marine Fitting Services

Propulsion repairs are carried out to ensure the ship’s propulsion system is functioning optimally, maintaining vessel performance, efficiency, and safety. Below is a list of repairs that we provide:

Inspection and Assessment

The first step in propulsion repairs is a comprehensive inspection and assessment of the entire propulsion system. This includes examining the main engine, propulsion shafts, bearings, seals, propellers, and thrusters. Our team of experienced engineers and technicians identify any signs of wear, damage, misalignment, or inefficiencies during the inspection process.

Propeller Repairs

Propellers are crucial components that convert engine power into propulsion force. Propulsion repairs may involve repairing propeller blades, removing dents or distortions, and correcting imbalances. Damaged or worn-out propellers can negatively impact the ship's performance, fuel efficiency, and stability.

Main Engine Overhaul

The ship's main engine is the heart of the propulsion system, and periodic overhauls are necessary to maintain its reliability and performance. During an engine overhaul, various components are inspected, cleaned, and repaired or replaced as needed. This may include pistons, cylinders, valves, fuel injectors, cooling systems, and other engine parts.

Thruster Maintenance

Thrusters are auxiliary propulsion systems used for maneuvering large vessels in confined spaces or when precise control is required. Propulsion repairs for thrusters involve inspecting and servicing the propulsion units, including electric motors, hydraulics, propeller blades, and control systems.

Shaft Alignment

Proper alignment of propulsion shafts is crucial for reducing vibrations and wear on the bearings and seals. These repairs may involve realigning the shafts to ensure smooth and efficient power transmission from the engine to the propeller.

Seal Replacement

Seals are critical components that prevent water from entering the ship's hull through the propeller shafts. Damaged or worn-out seals must be replaced to maintain a watertight system and prevent potential flooding.


Properly balanced rotating components, such as propellers and shafts, are vital for smooth and efficient propulsion. We will balance these components to reduce vibrations and prevent premature wear.

Performance Testing

After completing propulsion repairs, Guyana Port Inc. conducts performance testing to verify the effectiveness of the repairs and ensure that the propulsion system is operating within optimal parameters.

Compliance and Certification

Propulsion repairs must adhere to industry standards and regulations. Once the repairs are completed, the ship undergoes inspection and certification to confirm compliance with safety and environmental regulations.

Preventive Maintenance

In addition to addressing specific issues, propulsion repairs in our yard often include implementing a preventive maintenance schedule. Regular maintenance helps identify and address potential problems before they escalate, ensuring the propulsion system's long-term reliability and reducing the risk of unexpected breakdowns.
