Can vibration measurements prevent machinery failures?

Yes. Trending vibration levels helps identify developing faults before they result in major failures or unplanned downtime.

Is the service performed onboard?

Yes. Our engineers perform all measurements onboard while the vessel is in port or during scheduled maintenance periods.

Do you provide recommendations after the inspection?

Yes. Every inspection includes analysis, findings, and practical maintenance recommendations based on the measured vibration data.

How hot spot and electric load disballance looks like. To prevent real world problems we provide a real investigation.

Safeguarding the Seas: Onboard Thermal Imaging for Marine Electrical Systems
When a ship is out at sea, a sudden electrical failure isn’t just an inconvenience it’s a major operational hazard, a costly downtime event, and a severe safety threat. Because you can’t fix what you can’t see, Marine Thermography (Thermal Imaging) has become critical for predictive maintenance, capturing invisible anomalies under real operational loads before they manifest into catastrophic failures.

The Invisible Threats: Hot Spots & Load Imbalances. Our professional thermography services primarily target two critical electrical vulnerabilities: The Danger of “Hot Spots”: Localized areas of elevated temperature usually caused by loose or corroded terminations and degraded switch contacts. Left unchecked, this thermal runaway can melt insulation, destroy components, or spark an electrical fire. Identifying Load Imbalances: When one phase carries significantly more current than the others, it causes uneven thermal stress. Continuous imbalance degrades insulation prematurely, overloads the neutral line, and causes unexpected breaker tripping. Operational Advantage: Inspections are conducted during live operations. There is no need to shut down power or disrupt the crew’s workflow to locate faults.

Strategic Port Coverage Across Europe
To minimize vessel deviation, our certified technicians mobilize quickly across major European shipping lanes and hubs:

• Spain & Canary Islands: Full coverage across mainland hubs (Algeciras, Valencia, Barcelona, Bilbao, Castellón, Tarragona) and the Atlantic crossroads (Las Palmas, Tenerife).
• Gibraltar: Rapid mobilization for vessels anchoring or bunkering in the Strait.
• French Ports: Complete service across major gateways including Marseille Fos, Le Havre, and Dunkirk.
• Poland: Dedicated Baltic Sea support at the Port of Gdańsk.

Why Choose Professional Marine Thermography?
Prevent Costly Downtime: Catch component degradation months before failure to plan repairs during scheduled port stays.

Enhance Safety: Drastically lower the risk of electrical fires, which are among the most dangerous events at sea.

Class Survey Compliance: Meet the growing requirements of insurance underwriters and classification societies.

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

Our onboard automation service includes: System Health Check, Full Function Test, Alarm & signal verification, Electronic module repair, Controller HMI diagnostics, Commissioning and operational validation. Service can be performed directly onboard during shipyard stays or port calls.

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.
