Adnoc Refining is evaluating technical bids from consultants for the front-end engineering and design (feed) work on a project to debottleneck and upgrade condensate refining trains at Ruwais Refinery East (RRE).

MEED previously reported that the refining arm of Abu Dhabi National Oil Company (Adnoc Refining) had issued a tender for the project in early February.

Technical bids for the feed works were submitted on 7 March, a source said.

“Adnoc has sought technical clarifications from the bidders and is conducting technical meetings with the consultants presently,” the source added.

Adnoc Refining is understood to have issued the tender for feed works to the following firms:

  • Fluor Corporation (US)
  • GS Engineering & Construction (South Korea)
  • Tecnicas Reunidas (Spain)
  • Technip Energies (France)
  • Wood Group (UK)
  • Worley (Australia)

It is understood that US-headquartered KBR, which initially received the feed tender, has declined to bid.

Being in an early stage of development, it is premature to determine the overall value of the project, a source previously told MEED.

Adnoc Refining has a total oil refining potential of 922,000 barrels per day (bpd), with RRE’s output standing at 420,000bpd. Ruwais Refinery West’s (RRW) capacity is 417,000bpd while the Abu Dhabi Refinery (ADR) handles 90,000bpd.

The project assumes critical importance for Adnoc Refining as it plans to start phasing out ADR from the fourth quarter of 2022 and requires the RRE asset to handle its condensate feedstock, plus additional volumes.

Adnoc Refining issued the solicitation of interest for the project in November last year.

All prominent engineering service providers are understood to have submitted expressions of interest by mid-January, another source said.

Project objectives

Adnoc Refining intends to raise the condensate refining capacity of four processing trains at RRE by up to 161,000bpd each with the upgrade project.

The units need to be upgraded to handle condensate feedstocks of 125,000bpd from the Thammama onshore field and 27,000bpd from the Hail and Ghasha offshore field.

The trains must also be equipped to potentially handle up to 25,000bpd of liquids from the Upper Zakum field or the Murban development or other categories, with 8,000bpd of Upper Zakum crude being the base case scenario.

Adnoc Refining also plans to execute modifications to existing equipment in the condensate units such as the main fractionator and trim coolers, for which new equipment such as desalter trains and crude pumps could be required.

Scope of work

Adnoc Refining intends to execute the feed works on the proposed project in two stages.

In the first stage, the company expects the feed consultant to finalise the design strategy based on the selection of the suitable conceptual design and conduct cost estimation, value engineering and other studies on the project.

In the second stage, the chosen consultant would be required to perform feed works to develop the engineering, procurement and construction (EPC) scope of the project, undertake optimisation, adequacy and energy management studies and design specifications for provisional EPC packages pertaining to the additional equipment.
