Dayna O'Brien

Dayna O'Brien serves as the primary procurement lead at Portsmouth Naval Shipyard Gf, overseeing the acquisition of mission-critical industrial and technical services essential to sustaining U.S. Navy submarines and surface vessels. In this role, she manages a diverse portfolio of contracts spanning fabrication, maintenance, testing, and logistical support, ensuring alignment with the shipyard’s strategic priorities in naval vessel modernization and operational readiness. Her acquisitions are characterized by a strong emphasis on precision engineering, high-integrity component supply, and industrial infrastructure support, requiring rigorous compliance with defense procurement standards and naval technical specifications. O’Brien maintains consistent working relationships with key contractors including NORTHROP GRUMMAN SYSTEMS CORPORATION for advanced fabrication and systems integration, UNITED RENTALS for heavy equipment and industrial support, PATRIOT GLOBAL LODGING LLC for mission-critical personnel housing, KARDEX REMSTAR for automated parts storage systems, and BSE PERFORMANCE for specialized maintenance services. These partnerships reflect a balanced approach between large prime contractors delivering complex technical solutions and niche vendors providing essential ancillary services critical to shipyard operations. Her contracting patterns demonstrate a strong inclination toward small business participation, with nearly half of all awards structured as total small business set-asides under FAR 19.5. This reflects a deliberate strategy to foster vendor diversity and enhance local industrial capacity, particularly among firms certified under socioeconomic programs such as HUBZone and SDVOSB, while maintaining flexibility for non-set-aside acquisitions where scale or technical specificity demands broader market engagement. O’Brien’s primary NAICS focus areas include 315990 for specialized apparel and protective gear, 541380 for non-destructive testing and materials analysis, 332722 for precision fastener manufacturing, 811310 for industrial machinery repair, and 611699 for technical workforce training. These reflect a technical domain expertise in naval industrial maintenance, quality assurance, and workforce development, underpinning the shipyard’s mission to sustain naval combat readiness through precise, reliable, and compliant procurement practices.
