Everllence will deliver four compressor trains to MODEC for a new floating production storage and offloading (FPSO) vessel for the Hammerhead field offshore Guyana. It is the seventh FPSO project developed by ExxonMobil Guyana Limited, the operator of the field. The vessel will be moored approximately 125 miles (200 km) off the coast at a water depth of around 3360 feet (1025 m) and will have an initial production capacity of 150,000 barrels of oil per day (bpd), bringing total installed storage capacity of 1.5 million barrels of oil.
Once operational, the new FPSO will contribute to Guyana’s growing role in the global energy market, raising the country’s total production capacity to almost 1.5 million bpd. First production is expected in 2029.
Upon start-up, Everllence’s compressor systems will help maximize the quantity and efficiency of gas production from the Hammerhead field. The scope of supply for the project includes a total of four barrel-type RB compressor trains: two as low-pressure gas compressors and two as export gas compressors.
All compressors will be electrically driven. While the low-pressure gas compressors will be driven with variable frequency drives, the export gas compressors will be driven with fixed speed drives. The compressors will be designed, manufactured and tested at Everllence’s facility in Zurich, Switzerland.
The scope further includes a comprehensive dynamic process simulation, enabling the compressor systems to operate at their full potential in terms of process efficiency.
In April 2025, MODEC was awarded the full engineering, procurement, construction, and installation scope to develop a FPSO vessel for the Hammerhead Project following a final investment decision by ExxonMobil Guyana.
