Bahrain Petroleum Company (Bapco) has invited companies to submitting engineering, procurement and construction (EPC) bids for the expansion of the Sitra refinery in Bahrain.

Companies have been set a deadline of 5 October to submit bids for the project, which is expected to cost about $5bn.

The Bapco Modernisation Programme (BMP) aims to rehabilitate the refinery as well as increase capacity to 360,000 barrels a day (b/d) from 267,000 to b/d. This will be achieved by integrating several units into the existing refinery, WorleyParsons said.

Earlier this year Bapco asked companies to express interest in being first-tier bidders for the tender. The first-tier bidders then formed consortiums with other companies. According to Reuters, consortiums planning to bid are:

  • JGC Corp (Japan)/GS Engineering & Construction (South Korea)
  • Technip (France) / Tecnicas Reunidas (Spain) / Samsung Engineering (South Korea)
  • Fluor (US) / Hyundai Engineering & Construction (South Korea) / Daewoo Engineering & Construction (South Korea)
  • CB&I (US) / Petrofac (UK)

Bapco awarded the project management consultancy (PMC) contract for the scheme to Australia-based WorleyParsons in December in a deal worth about $87m.

In October 2014, Bapco awarded a $100m-plus contract to US-based Chevron Lummus Global to carry out design and engineering work on Sitra refinery.

The company, a joint venture between the US’ CB&I Lummus and Chevron, will also license its technologies for residue hydrocracking and vacuum gasoil hydrocracking units as part of the refinery’s modernisation programme.

A month earlier, Bapco had awarded France’s Technip a $55m front-end engineering and design (feed) contract for the refinery’s residue conversion unit (RCU).
