Wood Group Engineering has selected Able's Nucleonic level detectors to assist in modifications to the diesel-storage facilities on Lomond and North Everest oil fields.
The Nucleonic level instrumentation has been fitted to the two diesel-storage tanks located on both platforms.
These tanks store diesel fuel as a contingency should the platform's own fuel gas system become unavailable.
Diesel fuel is also supplied to utility systems and users such as cranes, lifeboats and portable diesel-driven equipment.
The design of the diesel-storage tanks includes a vent at the top of the tank that could potentially allow diesel overflow to the platforms open drains system.
If an overflow was to occur, there is the possibility that diesel fuel may drain to sea via the open drains system (if the drains were swamped with diesel) resulting in a potential environmental incident.
The change in design of existing instrumentation to precise nucleonic level instrumentation provides the platforms with more accurate information and assurance that the probability of a potential incident is minimised.
The output from the nucleonic instrumentation has increased the reliability in the operation of the diesel systems.
Robust and reliable instrumentation is critical for this application as the diesel-storage tanks form part of the platforms' crane pedestal structure.
The cranes are situated on north and south sides of the platforms and are exposed to all weather conditions.
The Able Nucleonic level detectors are fitted on the side of the diesel tanks close to an access platform for personnel to monitor condition of the instrumentation and allow maintenance.
