Telic Engineering received an assignment from Woodward Netherlands to support their client Baker Hughes, a GE company, with troubleshooting concerning regular communication errors with I/O devices. This impacted the reliability of one of the two turbines used for power generation on board the Alvheim FPSO operated by Aker BP located offshore Norway.
The troubleshooting resulted in identifying and resolving faults in the communication wiring after which the LM2500 base dual fuel DLE gasturbine could be put reliable in operation again.
Additional services provided were corrective actions and recommendations for improving the electrical health of the control system power distribution, and troubleshooting a liquid fuel shutoff valve.
The Alvheim field is located in the central part of the North Sea, close to the UK sector. It consist of the main field Alvheim, and the satellite fields Bøyla, Vilje and Volund.
Production is from the Alvheim field is done via the Alvheim FPSO, which started in 2008 after being converted from the multipurpose shuttle tanker (MST) Odin. The water depth in the area is between 120 and 130 meters.
Alvheim had been producing beyond expectations and there has been a gradual increase in the resources, mainly as a result of infill drilling.
Oil is transported from the field with shuttle tanker, and associated gas is exported through the Scottish Area Gas Evacuation (SAGE) system to St Fergus in Scotland.
