ABB drives control the compressors of the world's longest gas export pipeline
This document describes ABB's MEGADRIVE‑LCI variable speed drive system supplied for the Ormen Lange offshore gas field compressors. It details the drive configuration, including a four‑winding transformer, filter system, 12‑pulse converter and a 48 MW synchronous motor, and presents the main technical data of the system.
The brochure also outlines the benefits of using electric variable speed drives for large compressors—high reliability, low maintenance, high efficiency and reduced emissions—and summarizes the extensive testing performed at ABB’s facilities to verify performance, efficiency and compliance with customer specifications.
