The subsea umbilicals, risers, and flowlines (SURF) facilities for the Yellowtail project will be the largest to date offshore Guyana with over 50 development wells planned, making the contract for the supply and installation of this equipment among the biggest this century.
For comparison, Liza Phase 1 comprises 17 development wells, Phase 2 – 30 and Payara – 41.
According to the development plan, produced well stream fluids which include associated gas will be transported through subsea flowlines to the One Guyana FPSO being built by SBM Offshore. The Dutch floater specialist confirmed earlier this month the contract awards for what will be the biggest capacity FPSO it has built so far for ExxonMobil’s operations in Guyana. The vessel will be designed to produce 250,000 barrels of oil per day, with associated gas treatment capacity of 450 million cubic feet per day and water injection capacity of 300,000 barrels per day. It will be spread moored in water depth of about 1,800 meters and will be able to store around 2 million barrels of crude oil.
Most of the major SURF equipment will be preassembled, pre-tested, and shipped directly to the offshore Yellowtail development area from their points of origin. Other minor equipment, supplies, and materials will be temporarily staged at a shorebase, and associated laydown yards and warehouses until transferred offshore for installation or use.
Subsea giant TechnipFMC has landed a major subsea equipment deal for the Yellowtail project. The work scope includes as much as 51 enhanced vertical deepwater trees and 12 manifolds, together with associated controls and tie-in equipment. TechnipFMC defines the Yellowtail contract as large, meaning worth between $500 million and $1 billion.
“The latest subsea job is set to eclipse previous Stabroek phases,” according to Rystad Energy’s analysis.
So far, TechnipFMC has secured almost 140 subsea trees for the Stabroek development projects alone. Rystad Energy said this is significant for a subsea market that saw around 140 subsea trees awarded globally in 2020.
Exxon announced its Final Investment Decision (FID) for the mega US$10 billion project on April 4 after authorities granted the environmental permit and a production license following a period of review.
Yellowtail is projected to achieve first oil by 2025.
