Case Study: Offshore Generator Servicing for North Sea Gas Platform

In 2019, we supplied two bespoke diesel generators to an offshore gas platform in the North Sea, providing a critical power solution if the on-site microturbines were unable to meet operational demand. Both generators were designed specifically for an offshore environment, with full EX ratings to meet the stringent safety requirements associated with gas production facilities.

The installation comprised two identical generator sets:

• Rating: 288 kW per unit

• Configuration: One NDG (Normal Duty Generator) and one EDG (Emergency Duty Generator)

Both units were engineered to operate reliably in hazardous-area conditions, ensuring continuity of power.

Fault Identification

More recently, a fault was reported where both generators intermittently lost recorded run-hour data on the control display. Given the importance of accurate run-hour logging for servicing schedules and offshore compliance, a structured investigation was undertaken.

The investigation included the engine, controllers and DC circuits. An intermittent issue was identified within the generator control circuitry, affecting the stability of the DC control signal. Once isolated, it was quickly resolved.

Expert Offshore Generator Control System Servicing

Following rectification, control system stability was restored and run-hour data logging returned to normal operation across both generators. The generators were returned to full operational reliability with no further recurrence of the issue. The site continues to benefit from a safe, compliant, and dependable backup power solution, supported by our ability to diagnose and resolve complex control and electrical faults in offshore hazardous environments.
