Saipem has successfully completed its designated scope of work for the development of the Yellowtail field, operated by ExxonMobil Guyana Ltd., located approximately 1,800 metres underwater within the Stabroek Block offshore Guyana.
Awarded the contract in 2022, Saipem was responsible for the Engineering, Procurement, Construction, and Installation (EPCI) of the Subsea Umbilical, Riser, and Flowline (SURF) system for the Yellowtail field. The installation of the rigid flowline and steel lazy wave risers was executed by the FDS2 J-lay vessel during an early 2024 campaign. The project concluded in 2025, with the Saipem Constellation carrying out the installation of flexible risers, umbilicals, and the connection of the pre-laid rigid riser to the floating production storage and offloading (FPSO) unit. Additionally, the Normand Samson, a Saipem-chartered Multi-Support Vessel (MSV), supported the offshore campaign from mid-2024, providing subsea pre-commissioning, surveys, light construction, and the installation of flowline jumpers fabricated at Saipem’s yard in Georgetown. All offshore and onshore activities adhered to the highest standards of safety and quality, completed on schedule.
This project reinforces Saipem’s strategic position and execution capabilities in large-scale deepwater developments, building on the experience gained from previous projects for ExxonMobil Guyana, including Liza Phase 1 and 2, Payara, and the UARU offshore phase, which commenced in March 2025. By leveraging operational efficiency and expertise in managing complex projects, Saipem contributed to an advanced production start-up of the Yellowtail field, achieving nearly a four-month acceleration.
Saipem remains committed to delivering innovative engineering and technological solutions in challenging geological environments such as the Stabroek Block. The company integrates its acquired expertise with a focus on sustainability and local development, continuing to collaborate closely with local communities and stakeholders to foster economic growth and the development of specialised skills on-site.
