Main Contractor : Maire Tecnimont
Location : Ghasha, Abu Dhabi, UAE
Award Date : 2023-Q4
Background
Adnoc is planning the development of a major oil and gas field in Abu Dhabi. The Hail and Ghasha Development onshore facilities will include an onshore development that focuses primarily on the Manayif utilities and tie-ins, and focus on the construction of the Manayif gas processing plant. The development design combines innovative decarbonisation technologies into one integrated solution. The project will capture 1.5 million tonnes per year (mtpa) of CO2, while low-carbon hydrogen is produced that can replace fuel gas and further reduce emissions. The project will also leverage clean power from nuclear and renewable sources from the grid.
Project Status
As of September 2024, Tecnimont has started the initial work on Hail and Ghasha onshore facilities. The $8.74 billion contract includes the delivery of the onshore, carbon dioxide, and sulfur recovery and handling facilities.
Project Scope
The onshore facilities will consist of several key components. These include two gas processing units and three Sulphur Recovery Units (SRUs), which share a common CO2/H2 recovery section. Additionally, there will be associated utilities and offsite export pipelines.
In terms of Manayif utilities and tie-ins, the facilities will feature utilities and off-sites, export pipelines and tie-ins, as well as a main control building. Early works and non-process buildings will also be part of the Manayif gas processing plant, which will serve as the main Onshore Processing Plant (OPP). This plant will include gas gathering, gas processing, and the SRU.
The key figures for the onshore facilities highlight their scale and capacity. The total plant area will cover 4.1 square kilometers. The facilities will incorporate approximately 270,000 tons of equipment in steel structures and piping. Additionally, there will be around 25,000 kilometers of electrical and instrumentation cables, along with 550,000 cubic meters of concrete.
Project Finance
Adnoc is the project client. It is 60% owned by Adnoc and 40% owned by Occidental Petroleum (OXY).
The Ghasha ultra-sour gas concession encompasses the Hail, Ghasha, Dalma, Nasr, Sarb, Bu Haseer, Shuweihat, and Mubarraz offshore sour gas fields, with stakeholders including Adnoc (55%), Eni (25%), PTT Exploration and Production Public Company (10%), and OMV and Lukoil (5% each).
Adnoc has signed the PMC framework agreement with 3 engineering firms for the Ghasha concession and has been awarded to KBR, SNC Lavalin, and TechnipFMC. The firms will share a 50:30:20 percent ratio, with KBR as the lead project management firm followed by SNC Lavalin and Technip FMC. PMC services will be provided for all the Hail and Ghasha Development project packages.
