Keeping your vessel in control, where it matters most.
Expert electronics controller servicing for engine room and cargo control room systems ensuring accuracy, reliability, and safe operations at sea.

Behind every smooth voyage is a network of electronics quietly doing the hard work. In the engine room and cargo control room, controllers manage the systems your crew relies on every day and when they don’t perform as they should, operations can quickly be disrupted.

That’s where our electronics controller servicing comes in. We work hands-on with control systems in both the engine room and cargo control room, making sure everything responds accurately, communicates properly, and operates the way it was designed to.

In the engine room, we service controllers for main and auxiliary engines, generators, pumps, and fuel systems. Our focus is simple: identify issues early, correct unstable signals, eliminate false alarms, and help prevent unexpected shutdowns that cost time and money.

In the cargo control room, we support the electronics behind cargo pumps, valves, tank gauging, and monitoring systems. Reliable controls mean safer loading and discharge operations, better visibility for operators, and greater confidence throughout every cargo cycle.

We understand the realities on board tight schedules, demanding conditions, and no room for guesswork. That’s why our approach is practical, efficient, and focused on real results. Whether it’s routine servicing or urgent troubleshooting, we help keep your systems dependable when you need them most.

Vibration Measurement Services Onboard

Petrik Naval provides professional vibration measurement services for rotating and turning machinery parts in accordance with international ISO standards. This service is essential for assessing machinery condition, preventing unexpected failures, and maintaining safe and efficient vessel operations.

Our vibration measurements are performed in compliance with ISO 10816 – Evaluation of machine vibration by measurements on non-rotating parts, a widely recognized standard used for motors, pumps, generators, and fans. Using calibrated instruments and approved measurement procedures, our qualified service engineers collect vibration data under normal operating conditions to ensure accurate and reliable results.

The measured vibration levels are analyzed and compared against ISO 10816 acceptance criteria to identify imbalance, misalignment, bearing deterioration, looseness, or other developing mechanical faults. Based on the findings, Petrik Naval provides clear assessments of machinery condition along with practical recommendations for corrective actions when required.

Detailed measurement reports support maintenance planning, compliance audits, and technical decision-making. Through systematic vibration monitoring, Petrik Naval helps shipowners and operators improve equipment reliability, extend machinery service life, reduce maintenance costs, and ensure continued compliance with international vibration standards across their fleet.

Marine Boilers, Flue Gas, Inert Gas Generators

Petrik Naval provides comprehensive marine boiler repair, commissioning, and adjustment services to ensure safe, efficient, and reliable boiler operation onboard vessels. Our experienced service engineers support shipowners and operators by maintaining boiler systems in full compliance with OEM guidelines and Class requirements.

Our scope includes thorough alarm and safety verification, ensuring all protective functions operate correctly under normal and fault conditions. Critical components such as sensors, valve actuators, salinity probes, and level sensors are inspected, tested, and calibrated to guarantee accurate monitoring and dependable control. We also service burners and fuel oil systems, focusing on proper atomization, stable combustion, and safe ignition sequences.

Special attention is given to burning efficiency, where precise adjustment of air to fuel ratios and combustion parameters helps reduce fuel consumption, emissions, and operational costs. Proper tuning not only improves thermal efficiency but also minimizes soot formation and unplanned shutdowns.

Through systematic testing, fine adjustment, and detailed reporting, Petrik Naval ensures marine boiler systems perform reliably and efficiently. Our services enhance safety, extend equipment life, and support uninterrupted vessel operations, delivering confidence and value to ship operators worldwide.

Marine Auxiliary Generator

Efficient operation of a marine auxiliary generator is essential for reliable power supply, reduced fuel consumption, and long-term equipment health. Proper commissioning and fine adjustment on both the electrical and mechanical sides ensure optimal performance under all operating conditions.

On the electrical side, AVR (Automatic Voltage Regulator) commissioning plays a critical role in stabilizing voltage output and achieving effective load sharing between generators operating in parallel. Correct AVR tuning minimizes voltage fluctuations, improves power quality, and prevents uneven load distribution, which can lead to overheating and unnecessary fuel use. Accurate settings allow generators to respond smoothly to load changes, ensuring stable and efficient electrical power throughout the vessel.

On the engine side, GOV speed regulator (governor) dynamics adjustment directly influences fuel efficiency and engine response. Fine-tuning the governor improves frequency stability, reduces hunting, and ensures balanced load sharing between generator sets. Proper dynamic adjustment allows the engine to react precisely to load variations, lowering fuel consumption while maintaining reliable power output. This process also reduces mechanical stress and extends engine service life.

Together, AVR commissioning and governor optimisation form a comprehensive approach to auxiliary generator efficiency. When performed by experienced marine service engineers, these adjustments result in improved fuel economy, stable power generation, and dependable operation, supporting safe, economical, and environmentally responsible vessel performance.

VECS Vapour Emission Control System

Petrik Naval provides onboard calibration and verification service through qualified service engineers. The system is inspected, tested, and calibrated in accordance with OEM specifications, Class requirements, and statutory regulations. All sensors, control units, and safety functions are verified to ensure accurate performance and operational reliability. Functional testing is conducted under real operating conditions to confirm system integrity. Upon completion, Petrik Naval delivers clear documentation and detailed reports, supporting compliance, safe operations, and uninterrupted service during cargo handling and voyage execution.
