Saudi Aramco has launched tenders for multiple offshore engineering, procurement, construction and installation contracts involving its Zuluf offshore upgrade project, worth up to $2.5 billion of business in total.

Aramco recently floated tenders for a quartet of Zuluf EPCI projects as a part of its long-term agreement (LTA) with international contractors, three sources familiar with the tender process told Upstream.

The state-owned giant has ramped up its spending on offshore brownfield, maintenance and incremental projects this year on the back of sustained high oil prices.
