About the company
Fluor Marine Propulsion, LLC, doing business as Fluor Offshore Solutions, is a limited liability company and subsidiary of Fluor Federal Services Inc. based in Greenville, South Carolina, that performs naval nuclear propulsion engineering, research and development, and facility operations and maintenance as a subcontractor to the Department of the Navy and the Department of Energy National Nuclear Security Administration. The vendor operates overwhelmingly as a subcontractor (98% of recent awards) rather than a prime, with 85 of 87 awards in the source data structured as sub-awards under larger federal contracts.
Fluor Marine Propulsion's footprint is concentrated almost entirely within nuclear propulsion programs. The vendor's 87 awards span two customer agencies and carry a combined potential value of $38.76 billion, with $28.7 billion obligated (74% of potential value). The Department of the Navy Naval Sea Systems Command anchors one award valued at $20.26 billion — a multi-year management and operations contract for the Naval Nuclear Laboratory and Naval Nuclear Propulsion Program that accounts for 52% of the vendor's combined potential value. The Department of Energy National Nuclear Security Administration funds 86 awards valued at $18.5 billion, representing 48% of potential value. All 87 awards fall under NAICS 541712 (Research and Development in the Physical, Engineering, and Life Sciences), with one PSC-coded as Nuclear Reactors and another as Operation of Government-Owned Contractor-Operated R&D Facilities. Recent activity shows a sharp spike: the source data spans from July 2018 (two awards) to December 2025 (85 awards), with the bulk of awards emerging in 2025 as sub-tasks under the Navy and NNSA prime contracts.
On SCI-reportable federal service contracts above the $150,000 threshold, Fluor Marine Propulsion invoiced $5.87 billion across FY2022 through FY2024 as a prime contractor ($1.88 billion in FY2022, $2.05 billion in FY2023, $1.95 billion in FY2024). The FTE trajectory reported in SCI shows 5,198 full-time equivalents delivered in FY2022, declining to 2.2 FTEs in FY2023 and 1.8 FTEs in FY2024 — a data artifact reflecting contract reporting methodology rather than actual workforce contraction; the SCI dataset captures only contracts above the reporting threshold and counts FTEs at the contract level. Government-paid hourly rates on prime contracts run a median of $3,091.50 per hour, with rates spanning from a 10th percentile of $753.30 per hour to a 90th percentile of $3,539.61 per hour, reflecting a mix of labor categories from technicians through senior engineers. Across SCI-reportable prime contracts, subcontractors perform an average of 67% of total contractor hours, with 174 named subcontractors reported across the vendor's prime service contracts — a posture indicating Fluor Marine Propulsion serves as a management and coordination hub for a large, distributed supply chain of specialized vendors supporting naval nuclear R&D and facility operations.
