Lundin Norway has developed a unique energy management system for use on the Edvard Grieg platform. The system will result in significant savings in terms of both economy and the climate.
By linking real-time production data with energy consumption information for all parts of the facility, this newly-developed system can help us optimise operations and use energy with maximum efficiency. The potential savings are huge.
All production installations on the Norwegian Shelf measure their energy consumption. This information is reported to the authorities in connection with emission permits and calculation of CO2 tax. Lundin’s objective was to automate the reporting process to avoid manual work. In the course of this work, Lundin saw that they could take this a giant step further – from energy monitoring to advanced energy optimisation.
Technology development – the “Lundin way”
The digital infrastructure was in place on the Edvard Grieg platform. Operating data from all parts and components in the process and export facility are continually fed into a condition monitoring system. This made it possible to develop the new energy management system as an application on the already existing system.
The timespan from idea to operational system was just five months. Four people spent parts of their working hours on the project during this period – three from Lundin and one from Honeywell, which delivered the condition monitoring system. And the development was accomplished without having to invest in new hardware or software.
Lundin likes to work this way. When the potential is in place, there is no reason to wait.
From measuring consumption to measuring loss
It started with simple measurements of energy consumed, now advanced algorithms and models are used to measure how much energy is potentially lost if the facility is not operated in an optimal manner.
The loss is further divided into two main categories. Operational loss, which is what we can have an impact on from hour to hour in the operation. And design loss, which is a result of limitations or properties of the individual components. For the latter category, physical changes or modifications are required to compensate for the loss of energy.
The energy management system makes it possible to retrieve loss and consumption reports for individual components. This will provide an excellent basis for assessing whether a modification or replacement will be profitable.
Loss calculations made by the system so far show that substantial savings can be achieved by optimising operations. And these benefits come both as cost savings, and as reduced greenhouse gas emissions.
Moreover, in theory, the development costs for the energy management system can be recovered in just a couple of days.
