About the company
Ocean Surveys, Inc., doing business as OSI, a Connecticut-based for-profit Subchapter S corporation, provides hydrographic surveying, coastal mapping, sediment sampling, and geospatial data collection services to federal agencies as a prime contractor (98% of recent awards) operating across full-and-open federal procurements without set-aside designations. OSI holds a $450 million multiple-award indefinite-delivery contract with the National Oceanic and Atmospheric Administration running through December 31, 2029, and operates under numerous Army Corps of Engineers IDIQ vehicles, positioning it as a specialized marine and geotechnical surveying vendor for coastal and inland water bodies.
OSI's customer concentration is extreme and anchored to two agencies. The National Oceanic and Atmospheric Administration dominates the potential-value ranking with 31 awards valued at $1.28 billion combined (100% of the combined potential value across all awards), driven by recurring delivery orders under NOAA's Hydrographic Surveys Division IDIQ for regional survey packages across the Northeast and Great Lakes. The Army Corps of Engineers Engineering District Philadelphia places the second tier by dollar value at $10.5 million across 33 awards, while the broader Army Corps (across all districts and functional areas) accounts for 116 total awards in the portfolio. Recent NOAA delivery orders include a $4.17 million firm fixed-price order for western Lake Erie hydrographic surveying (awarded July 1, 2026, completing March 26, 2027), a $2.58 million order for Cape Cod hydrographic services (awarded March 5, 2026, completing March 27, 2027), and a $4.03 million order for Mount Desert Island, Maine (awarded July 1, 2025, completing March 31, 2026). Historically, OSI has delivered $6.04 million for Gloucester and Boston Harbor surveying (awarded August 1, 2024) and $5.97 million for southwestern Lake Michigan (awarded July 7, 2023). Work is performed across United States territorial waters and inland waterways, with place-of-performance locations varying by survey geography (Sandusky, Ohio; Dennis, Massachusetts; Rockport, Maine; Boston, Massachusetts).
OSI's award portfolio shows modest recent activity (two awards in 2026, three in 2025, two in 2024) but sits on a large installed base of 244 total awards dating to 1981. Within the next twenty-four months, only two awards (combined potential value $6.8 million) face ultimate completion and recompete exposure. The vendor's NAICS concentration runs to Surveying and Mapping Services (71 awards) and Geophysical Surveying and Mapping Services (6 awards), with PSC coding dominated by Architect and Engineering General (110 awards) and Marine Engineering (10 awards). OSI operates as a pure prime on recent work — Service Contract Inventory data covering FY2022–FY2024 shows zero subcontractor engagement across nine SCI-reportable federal service contracts, with $16.9 million in invoiced revenue across that span ($3.4 million in FY2022, $5.5 million in FY2023, $8 million in FY2024) and FTE delivery scaling from 3.8 to 10.3 across the same period. On federal service contracts captured in SCI, government-paid labor rates ran a median around $428.76/hr, with senior labor pricing through $482.98/hr. OSI subcontracts minimally — only four sub-awards appear in the source data, including vibracoring services to EA Engineering, Science, and Technology for dredging material collection in Chesapeake Bay channels (awarded August 14, 2025) and geospatial survey work to AECOM Technical Services on a Lower Neponset River remedial task (awarded March 29, 2023). The vendor holds a subsidiary, OSI-Bet Joint Venture (an S-corp limited liability company small business joint venture), though no detail on its role in the prime footprint is provided in the source.
