PROJECT OVERVIEW
1.1
EPC for HAIL & GHASHA Development Project
The Hail & Ghasha Development (HGD) Project is of strategic importance to the Emirate of Abu Dhabi. The Project will develop the untapped oil and gas reserves from the highly sour Hail and Ghasha fields. Production is targeted to start by Q4 2027 with sustainable production of 1 BSCFD of Raw Gas, and max production of 82.5 MSBPD of Oil, 76.3 MSBPD of Condensate, 9000 TPD of Sulphur and 5030 TPD of NGL. In addition, Project will capture 1.52 million tonnes of CO2 per year taking ADNOC’s committed investment for carbon capture capacity. The Hail and Ghasha fields are situated offshore ABU DHABI about 140 km away from ABU DHABI mainland in water depths varying from 0 to 15 meters.
The HGD Project comprises the following:
Artificial Islands Construction;
Offshore package – EPC 01: Offshore Drilling Centers (DCs), Subsea Pipelines, Umbilicals, Power Cable Connections, Seawater Intake Structure, Bridges, Risers, Flare Structure, facilities at Ghasha Offshore Processing Plant (“GOP”);
Onshore package – EPC 02: Manayif Onshore Processing Plant (“OPP”), Manayif
Utilities, Offsite Pipelines & Tie-ins, Main Control and Other Buildings.
The HGD Project will be executed in a single phase approach. It will start production from three Drilling Centres (Reeah, Jzool & Seebah) in Ghasha Field to GOP and from Gaff Island in Hail Field to OPP. Remaining Drilling Centres, gas injection, and other associated facilities will be developed in ‘future’ to sustain production from Hail & Ghasha fields.

04: Identify HOLD for the same in the document. Contractor response is not satisfactory. Contractor to note that in offshore surface facilities, e.g. Piping classes are all based on GASCO DGS standards.
Mr Sachin Gaikwad Mr Chintan Desai
Hence Contractor to re-check and update the Onshore specifications.
Not legible.
Mr Taqveem Panzoo
Noted and implemented Contractor confirms that piping classes are based on GASCO DGS, as amended by FEED documentation. However, Contractor prefers not to mention such standards explicitly in the BEDD, since their use is only applicable to specific documents in continuity with FEED approach, whilst Appendix 1 is about general standards and specification that are generally applicable to project documentation. Contractor confirms also that the documents in which DGS are applicable, such standards are explicitly mentioned in the document body. This Image was provided by Company, and included by Contractor in approved title block procedure (ref. 1-CF0000-59- PRO-0004-00_04).

CONTRACTOR Confirmation / Explanation
In general all PROJECT documents refer to “CONTRACTOR”, as per Document Title block procedure, no.1-CF0000-59-PRO- 0004-00 template procedure. However, in dcouments like MRs that are addressed specifically to SUPPLIERS and SUBCONTRACOTRS, “CONTRACTOR” has been replaced with “PURCHASER”. Note and implemented Noted and implemented Noted. Incorporated as “DCs & HL”
HPP ed FGL are fixed during detail design development and shown in dedicated Plot Plans. They usually are not included in BEDD. Contractor therefore suggsts to not implemnt this comment. Air compression package design is aligned to BEDD specifications (as per ITT documentation): relative humidity varies from 97% at 43°C (max), average 70 % at 54°C to 50% (min). Design relative humidity for equipment is 100% at 42.5°C. Noted and implemented.
