Multiple people familiar with the development told Upstream that technical offers have been submitted by National Petroleum Construction Company of Abu Dhabi and Italy’s Saipem.

An award is expected in the second half of this year.

Clarifications are ongoing and commercial bids are likely to be submitted within weeks, one person said.
