Introduction
ExxonMobil has announced a final investment decision (FID) for the Hammerhead development offshore Guyana, marking the seventh project on the prolific Stabroek block. The announcement, made on September 22, 2025, confirms that the project has received the required regulatory approvals and is expected to come online in 2029. With a planned capacity of approximately 150,000 barrels of oil per day (bopd) and an investment of US$6.8 billion, Hammerhead will further solidify Guyana's position as a major offshore oil producer.
For EPC contractors, procurement managers, and piping suppliers, this FID signals a new wave of demand for high-quality piping components, including prefabricated piping systems and pipe supports. This article provides a factual overview of the Hammerhead project based on the official release, along with practical guidance for suppliers looking to position themselves for upcoming opportunities.
Project Overview
Hammerhead is the seventh development on the Stabroek block, following the successful startups of Liza Destiny, Liza Unity, Prosperity, and ONE GUYANA FPSOs, with Uaru and Whiptail under construction. The project will utilize a floating production storage and offloading (FPSO) vessel with a capacity of approximately 150,000 bopd. The total installed capacity on the block will reach 1.5 million bopd once Hammerhead comes online.
The US$6.8 billion investment will fund the development, including 18 production and injection wells. This brings the total committed funds for the seven approved projects to more than US$60 billion. ExxonMobil Guyana Limited operates the block with a 45% interest, while Hess Guyana Exploration Ltd. holds 30% and CNOOC Petroleum Guyana Limited holds 25%.
