Five leading international contractors or consortia are poised to battle it out for an offshore order from Qatargas involving two massive offshore compression "super-complexes" required for its giant North Field.

Qatargas recently issued tender documents to up to five leading pre-qualified contracting groups or companies for work on the second package of the giant compression facilities, Upstream heard from multiple people with direct knowledge of the tender process.

Up to three engineering, procurement and construction packages are up for grabs for the first phase of Qatar’s massive North Field Production Sustainability (NFPS) compression project, Upstream was told.
