The company said that the work will be completed within three years.
Meanwhile, the Arabian Pipes Company has announced that it has landed an $11.5m (SR: 43m) contract to supply welded steel pipes to Petrofac Saudi Arabia for the Jizan refinery project.
Thousands of workers are moving into place at Jizan following the award of seven contracts worth a combined $6bn to expand the refinery in November last year.
Once complete in 2016, the refinery will be capable of processing 600,000 barrels of oil per day.
When announcing the deals, Saudi Aramco's CEO Khalid A. Al-Falih said the project would lead to 1,000 direct and 4,000 indirect jobs during construction.
