MODEC has inked a purchase and sales agreement and secured a 20-year contract for the operation and maintenance of the floating production storage and offloading (FPSO) vessel for Shell’s Gato do Mato project.

This agreement follows the successful completion of the front-end engineering design (FEED) contract, awarded in March 2024.

Shell’s Brasil wing, Shell Brasil Petróleo, has made its final investment decision (FID) for the Gato do Mato oil field offshore Brazil.

The project involves a consortium with Shell holding a 50% stake, alongside partners Ecopetrol (30%) and TotalEnergies (20%). Pré-Sal Petróleo will manage the production sharing contract.

The Gato do Mato project is situated in the Santos Basin, spanning two blocks: BM-S-54 and Sul de Gato do Mato, secured in 2005 and 2017, respectively.

The Gato do Mato project is estimated to have a recoverable resource volume of approximately 370 million barrels.

The FPSO will produce 120,000 barrels of oil per day (bopd) and will be moored at a depth of approximately 2,000m.

MODEC will design the hull and all related topsides facilities for the FPSO, which will be moored by a SOFEC Spread Mooring system.

Stabilised crude will be stored in the FPSO tanks and offloaded to shuttle tankers for transport to markets.

A new-build, custom-made Next Generation Hull will be featured on the FPSO to support a 25-year design life.

The FPSO Gato do Mato will be the 19th FPSO developed by MODEC for Brazil and the second unit delivered directly to Shell by MODEC for operation in Brazil.

The prior unit was awarded to MODEC in April 2024 with MODEC’s responsibilities involving designing the FPSO’s hull and associated topside facilities.
