Esso Exploration and Production Guyana Ltd (EEPGL), a subsidiary of ExxonMobil Corporation, Hess Guyana Exploration Ltd (Hess), and China National Offshore Oil Corporation's subsidiary Nexen Petroleum Guyana Ltd (Nexen), are undertaking the Liza Deepwater Oil Field Development project in Guyana.

The project involves the development of a Liza oil field on the Stabroek block. The project will be implemented in phases.

It includes the drilling of 17 development wells, comprising production wells, water injection wells and gas injection wells clustered around two drill centers. The wells will be connected to a spread-moored floating production, storage, and offloading (FPSO) vessel through subsea umbilicals, risers, and flowlines ranging from 3.6km to 6.6km in length.

The FPSO vessel will include topside facilities, which can process fluids from the production wells at the rate of 100,000 barrels of oil a day (bpd). The hull of the FPSO will have the capacity to store 1.6 million barrels of processed crude oil, which will be periodically offloaded onto conventional tankers.

First phase includes completion of a floating production, storage and offloading (FPSO) vessel designed to produce up to 120,000 barrels of oil per day. The first will cost us$4,400 million.

Spectrum has been appointed to undertake the seismic survey for the project. Genesis Oil & Gas Consultants Ltd has been appointed as a front-end engineering and design (FEED) consultant.

In May 2016, EEPGL has shortlisted Modec International and SBM Offshore for front-end engineering and design studies. The other three pre-qualified bidders were BW Offshore Norway AS, Saipem S.p.A., and Bluewater Energy Services BV.

In August 2016, EEPGL and the other partners submitted a planning application to Environmental Protection Agency, Guyana to begin the environmental review process.

In November 2016, EEPGL submitted an application for a production license and its initial development plan for the project to Guyana Ministry of Natural Resources for approvals. The application includes development drilling, the operation of the FPSO, and subsea, umbilical, riser, and flowline systems.

On December 20, 2016, EEPGL appointed SBM Offshore to undertake the FEED for the FPSO of the project.

In the first quarter of 2017, EEPGL issued tenders for the engineering, procurement, construction and installation (EPCI) contractor for the subsea umbilical, riser and flowline (Surf) equipment and subsea production system (SPS) hardware packages of the project. The bid for the contract has been submitted by TechnipFMC plc, and a joint venture of OneSubsea, LLC and Subsea 7 S.A. (OneSubsea-Subsea 7).

On April 26, 2017, ExxonMobil awarded an EPCI contract to TechnipFMC plc. The scope of the contract includes 17 enhanced vertical deepwater trees and associated tooling, five manifolds and associated controls and tie-in equipment.

On May 10, 2017, ExxonMobil awarded an EPCI contract for the SURF package to Saipem. The scope of the contract includes engineering, procurement, construction, and installation of the risers, flow lines, and associated structures and jumpers. The award also includes transportation and installation of umbilicals, manifolds, and associated foundations for the production, and water and gas injection systems.

Saipem will deploy its flagship vessels FDS2 and the Normand Maximus to execute the works.

SBM Offshore is undertaking the detailed FEED design activities for the first phase, whereas design works for the second phase is expected to start in July 2017.

On June 16, 2017, EEPGL received approval for a final investment decision(FID) and Guyanese Government issued production license for the project.

In June 2017, ExxonMobil awarded FPSO contract to SBM Offshore for the second phase.

EEPGL will commence construction activities in 2019, with completion scheduled for 2020.
