Regulatory Compliance
Under IMO frameworks such as ISM and SOLAS, ballast water treatment systems must be properly maintained and calibrated to ensure safe operation. Inspection regimes like SIRE 2.0 and industry guidelines recommend periodic calibration typically annually or during scheduled maintenance cycles to verify system accuracy, safety, and environmental compliance.

The Hidden Gem

In a marine power plant with three 600 kW generators, a 2% voltage difference doesn’t just disappear when connected it converts into physical heat within the alternators.

Since the generators are sharing the kW load equally but have different voltages, the energy loss (in kW) comes from Circulating Current between them.

The Hidden Kilowatt Loss: Even if your ship load is constant, the engines must burn extra fuel to overcome the resistance of this internal current.

Estimated Loss: For a 2% voltage spread on 600 kW units, expect a continuous loss of 3 kW to 6 kW per generator (total system loss).

Fuel Impact: This equates to roughly 2 to 5 liters of extra fuel per hour (500 liters month ) just to maintain the “fight” between the two or three alternators.

Many vessels still operate with legacy automation platforms installed more than two decades ago. One example is the Efansa AMS PMS alarm and monitoring system, integrated onboard ships during major automation upgrades in the early 2000s. Today, several of these systems remain operational even though OEM support, spare parts, and software maintenance are no longer available.

Our engineering team recently carried out a full repair and recovery project for an Efansa Alarm Monitoring System (AMS) and Power Management System (PMS). These systems are essential for supervising engine room equipment, alarms, and operational parameters across propulsion, auxiliary machinery, and electrical distribution.

According to the manufacturer, Efansa has specialized for decades in the development and programming of control equipment and automation systems for industrial and marine applications, providing integrated engineering solutions and custom built control platforms.

From a functional perspective , a marine Alarm Monitoring System continuously supervises the operational status of critical ship machinery and alarms. These systems collect and display real time parameters from engines, generators, steering gear, and auxiliary systems, ensuring crew are alerted immediately in case of abnormal conditions.

Alarm systems also centralize machinery alarms, engineer call functions, alarm logs, and event history, allowing operators to track and respond to failures quickly.

Service Scope

Marine Regulatory Compliance

For vessels operating under UMS (Unattended Machinery Space) notation and modern inspection regimes such as SIRE 2.0, alarm and monitoring systems must remain fully operational and verified. Under IMO SOLAS and ISM Code safety management practices, critical alarm and monitoring instrumentation should be periodically tested and calibrated, commonly during annual surveys or planned maintenance intervals (typically 12 months), to ensure reliable machinery safety monitoring and compliance during inspections.

Sampling channels and alarms are verified onboard.

Ensuring gas detection systems are fully functional, calibrated, and correctly configured is essential for safe ship operations and regulatory compliance. Our IMS Hanla HGS-100 Gas Sampling System Service delivers the complete solution from health checks and flow troubleshooting to calibration, configuration, and certification so your vessel meets ISM, IMO, and SOLAS safety requirements.

The Hanla HGS 100 fixed gas sampling system is engineered to monitor air in tanks, pump rooms, and void spaces and instantly detect gas levels that exceed safe, programmable limits. It integrates multiple sensors, sampling lines, alarm units, and flow indicators to deliver reliable and continuous gas surveillance. Proper calibration and setup not only ensure detection accuracy but also guarantee that audible and visible alarms activate correctly in hazardous conditions.

Gas detection isn’t just about installation regular calibration against certified span and zero gases is a key safety requirement under maritime safety codes. IMO and SOLAS guidance call for test and calibration procedures to be established in the ship’s Safety Management System and executed as part of ongoing maintenance.

Our service scope includes health check, full functional testing, certification, calibration, repair, and commissioning all available onboard or at major European shipyards including Gdansk, Rijeka, Valencia, Cadiz, Burriana, and Damen Rotterdam, among others.

With SIRE 2.0 inspections placing increasing emphasis on documented maintenance and calibration records, ensure your HGS-100 system is not only compliant but performing optimally. Reach out to schedule your service and keep your vessel’s gas detection systems safe, accurate, and inspection ready.

OEM approved ODME, OMD, gas sampling, and portable instrument calibration services completed during dry dock in Varna Shipyard, ensuring full compliance with IMO and class requirements.

During a scheduled dry dock at Varna Shipyard, our service team successfully completed OEM approved calibration, repair, and measuring cell replacement for critical pollution prevention and monitoring equipment onboard.

The scope included RIVERTRACE SMART ODME and DECKMA OMD24 systems, where measuring cells were replaced strictly in accordance with OEM instructions. Each system underwent calibration checks, full function testing, and certification to confirm accurate oil content monitoring and alarm response before vessel redelivery.

In addition, the Consilium Salwico SW20202 gas sampling system was repaired and calibrated to restore reliable gas detection and sampling performance. Calibration of portable pressure and temperature instruments was also performed, ensuring traceable accuracy for onboard maintenance and operational checks.

Modern ODME and OMD systems are designed to deliver continuous, precise monitoring of oily water discharge, even under demanding operational conditions. Their modular construction allows for efficient servicing, while built-in diagnostics support fast verification after maintenance helping crews maintain compliance without unnecessary downtime. These systems play a critical role in protecting the marine environment while supporting safe and compliant vessel operation.
