Coming out of a challenging year with the COVID-19 severely affecting the global economy and causing a significant drop in demand for crude oil, national petroleum exploration and production company PTTEP is glad to get back on track with the installation and start-up of the Pemanis gas facility. The project’s wellheads sit offshore Malaysia’s Kuching shipyard and transmit information in regard to pressure, temperatures, gas metering, etc. back to an operations center on land via satellite.
PTTEP commissioned Swift Energy to provide a solar installation to power remote data gathering on the wellheads. The system included 48V VRLA batteries, 72 320W zone 1 solar panels wired in 48V, and eight Morningstar TriStar controllers. The TriStars include a Modbus interface which gathers data and passes it along to a Honeywell remote terminal unit (RTU) cabinet that transmits back to the operations center. The efficiency and dependability of Morningstar’s MPPT technology, along with its range of online resources to help simplify sizing and easily perform site and cost software analysis, made Morningstar a good choice for this and other Swift Energy projects.
