Marine Mechanical

At GURU-TECH A.M.S Marine Limited, we provide end-to-end mechanical engineering solutions for commercial vessels, offshore assets, patrol boats, tugboats, fishing vessels, and marine support equipment. Our certified marine engineers combine technical expertise with industry best practices to deliver reliable, efficient, and cost-effective maintenance, repairs, and installations.

Our Mechanical Capabilities

Complete Marine Engine Overhaul

We perform complete engine rebuilds, including dismantling, precision cleaning, inspection, measurement, machining, replacement of worn components, and reassembly of engine blocks, cylinder liners, crankshafts, pistons, connecting rods, and cylinder heads to restore optimal engine performance.

Advanced Engine Diagnostics & Fault Analysis

Using modern diagnostic equipment, we accurately identify mechanical and electronic faults through computerized diagnostics, bore-scope inspections, vibration analysis, cylinder pressure testing, and performance monitoring—reducing downtime and preventing costly failures.

Marine Engine Installation & Commissioning

Our engineers handle complete engine installation, alignment, foundation preparation, chocking, system integration, commissioning, and sea-trial performance verification to ensure safe and reliable operation from day one.

Preventive & Corrective Maintenance

We develop customized maintenance schedules based on engine operating hours and manufacturer recommendations while providing rapid corrective maintenance to minimize operational disruptions and extend equipment life.

Gearbox Repairs & Mechanical Troubleshooting

Our team specializes in diagnosing and repairing marine reduction gearboxes, clutch assemblies, propulsion couplings, shaft drive systems, thruster mechanisms, and other critical drive-train components.

Propeller Shaft Alignment & Precision Machining

Using laser alignment technology, we ensure accurate alignment of propeller shafts, stern tubes, intermediate bearings, and line shafts, reducing vibration, improving fuel efficiency, and extending equipment lifespan.

Fuel, Cooling & Lubrication System Overhaul

We service and rebuild complete fuel injection systems, high-pressure common rail equipment, cooling systems, plate and shell heat exchangers, seawater pumps, freshwater pumps, and lubrication systems for maximum engine reliability.

Turbocharger Inspection & Dynamic Balancing

Our workshop provides comprehensive turbocharger cleaning, inspection, balancing, component replacement, and performance restoration to maximize engine efficiency, power output, and fuel economy.
