TOKYO -- Kawasaki Heavy Industries of Japan has long trailed domestic rivals JGC and Chiyoda in the business of building oil and gas plants. But that is starting to change.

In August, Kawasaki Heavy won a roughly 150 billion yen ($1.44 billion) contract to build the world's first gas-to-gasoline plant in Turkmenistan. It will use new technology from a European company and work closely with its Japanese partner, Sojitz.
