Shell is working on reducing the net carbon footprint of its energy production, an initiative that includes retrofitting offshore facilities including platforms and NUIs (Normally Unmanned Installations) with solar power. Because NUIs see decades of operational use in the harsh weather of the North Sea, with plenty of snow and cloud cover, remote management is difficult. Instead of continuing with two diesel generators constantly online, in 2015, Shell began to simplify the normally unmanned installation by
removing process equipment that was no longer useful or redundant and retrofitting with solar.
Tideland Signal selected Morningstar TriStars, among other components, for use in its systems designed to meet the European Union’s ATEX-certification for use in hazardous locations. The controllers are ideal for the application, featuring everything necessary to reliably operate in the harsh environment. The solar installation makes it easier to maintain the NUIs with simpler equipment and lower emissions. Now, generators are only used for emergencies.
