Mission-critical ship repair, engine overhauling, and onboard systems support — where time, safety, and reliability are non-negotiable. Engineered for minimal downtime, across all major makes.
BulTech Group delivers technical services to commercial vessels in port and at anchorage — from major overhauls to scheduled maintenance. Every job is executed by experienced marine engineers, documented in detail, and aligned with class society standards.
End-to-end repair of hull structures, decks, piping, and mechanical systems. We handle steel renewals, plate cropping and inserts, pipe fabrication, tank cleaning and coating, and on-board fitting works — coordinated to minimise off-hire time and meet class society requirements.
Complete overhaul of two-stroke and four-stroke main engines and auxiliaries across MAN B&W, Wärtsilä, MAK, Yanmar, and Daihatsu. Services include piston pulling, liner and bearing inspection, fuel system reconditioning, timing and clearance adjustments, and full performance testing.
Troubleshooting, installation, and repair of onboard electrical and automation systems — switchboards, generators, alarm and monitoring systems, lighting, and navigation circuits. Insulation testing, megger checks, and cable routing carried out by qualified marine electricians.
Strip-down, ultrasonic cleaning, inspection, and reconditioning of Alfa Laval and Mitsubishi fuel oil, lube oil, and bilge water purifiers. Bowl balancing, disc stack replacement, and operational testing to restore separation efficiency and prevent unplanned shutdowns.
Service and overhaul of main and emergency air compressors, refrigeration and AC compressors. Valve plate replacement, piston ring renewal, intercooler cleaning, pressure testing, and lubrication system checks to factory specifications.
Workshop and on-board reconditioning of electrical motors — full rewinding, bearing replacement, shaft alignment, insulation resistance and high-voltage testing, dynamic balancing, and load testing before recommissioning.
Planned Maintenance System analysis and condition monitoring — vibration analysis, performance trending, lube oil sampling, and report generation aligned with class society and SOLAS requirements to keep machinery reliable between dockings.
Structured servicing programmes built around each vessel's operating profile — scheduled inspections, lubrication, calibration, and component renewals designed to extend equipment life, reduce failures, and protect operational schedules.
Our team consists of experienced marine engineers and technicians who understand what it takes to keep vessels operational, compliant, and safe at sea.
In commercial shipping, safety isn't a goal — it's the baseline. Our protocols are built around it.
Every hour in port is an expense. Our engineers deploy fast without compromising integrity.
All repairs and overhauls documented to meet major classification society requirements.
Experience across MAN, Wärtsilä, Sulzer, Hyundai, and other leading engine builders.
