A vessel's Power Management System (PMS) coordinates the generation and distribution of electrical power between generators, switchboards and major consumers. Depending on the vessel's configuration, the PMS can manage automatic generator starting and stopping, synchronization, load sharing, load shedding and blackout recovery. Our Power Management System Repair in Lome service provides troubleshooting, repair, testing and commissioning support for ships calling at Lome Port.

PMS TROUBLESHOOTING FOR SHIPS

PMS problems can affect the complete electrical operation of a ship. A generator may fail to start automatically, a circuit breaker may not receive the correct closing command, or the system may incorrectly identify the available generator capacity.

Our technicians can investigate PMS alarms, controller inputs and outputs, generator feedback signals, breaker status, voltage and frequency measurements and communication between the PMS and associated equipment.

This approach helps determine whether a problem originates from the PMS controller itself or from an external device such as a generator controller, protection relay, sensor or circuit breaker.

AUTOMATIC GENERATOR CONTROL

One of the important functions of a marine PMS is controlling generator availability according to electrical demand. When the running generators approach their configured operating limits, the system can initiate the start sequence for an additional generator. When demand decreases, surplus generating sets may be unloaded and stopped according to the programmed sequence.

Faults in this sequence can result from incorrect parameters, failed start signals, engine readiness problems, communication errors or incorrect breaker feedback.

We can check generator priority, start and stop thresholds, timers, permissive conditions and automatic control logic.

LOAD SHARING AND GENERATOR CONTROL

When several generators operate in parallel, the PMS must maintain appropriate distribution of electrical load. Problems with active load sharing can cause one generator to carry excessive kW while another remains lightly loaded.

Our ship PMS repair service in Lome can include inspection of load-sharing signals, governor interfaces, generator controllers and synchronization functions.

Reactive power and voltage-related problems may also require examination of AVR signals and excitation control, particularly when generators operate in parallel.

LOAD SHEDDING AND BLACKOUT PREVENTION

A PMS can help prevent a blackout by monitoring available generating capacity and disconnecting selected non-essential consumers when necessary. Heavy consumers may also be prevented from starting when insufficient generating capacity is available.

If a ship experiences repeated overload alarms, unexpected load shedding or generator trips, the PMS logic and load-priority configuration can be investigated.

The objective is to identify whether the problem comes from incorrect settings, faulty measurements, communication failures or an actual limitation within the vessel's power plant.

PMS CONTROLLER AND COMMUNICATION FAULTS

Modern marine PMS installations can include PLCs, dedicated generator controllers, HMIs, remote I/O modules and communication networks. A communication failure between these components may prevent correct automatic operation even when the generators themselves are functioning normally.

Our service can cover controller diagnostics, I/O checks, HMI alarm investigation, communication fault finding and replacement of defective control modules where required.

Existing PMS parameters and configuration should be documented before significant changes are made, allowing the system to be restored correctly after repair.

PMS TESTING AT LOME PORT

Following repair, the PMS can be functionally tested together with the relevant generators and switchboard equipment. Depending on the vessel's configuration, testing may include automatic generator start and stop, synchronization, breaker operation, load sharing, load shedding and blackout recovery sequences.

For a ship calling at Lome, technical attendance can be coordinated with the vessel's engineers and electrical team to minimize disruption to normal operations.

Our Power Management System Repair in Lome service is suitable for vessels experiencing generator automation faults, synchronization problems, load-sharing issues, PMS communication failures or abnormal blackout-prevention functions.

From a single controller fault to a wider generator and switchboard integration problem, systematic testing helps identify the actual source of the malfunction and restore reliable management of the vessel's electrical power system.
