About the company
Tidewater Environmental Services Inc., a for-profit maritime environmental services contractor based in Vancouver, Washington, delivers vessel waste removal, environmental remediation, and spill response services to federal agencies as a prime contractor on small-dollar purchase orders and definitive contracts, competing predominantly under full-and-open solicitations with no set-aside designation. The vendor is a child entity under parent Tidewater Holdings, Inc., and operates under the alternative business name West Coast Marine Services on several Coast Guard and Army Corps of Engineers awards.
Tidewater's customer base concentrates on maritime and water-resource agencies. Six agencies across recent awards account for 96% of the prime portfolio. The Army Corps of Engineers dominates by combined potential value — the main USACE organization holds 6 awards worth $202 thousand, while USACE Portland District holds 5 awards worth $77 thousand — followed by the U.S. Coast Guard (8 awards, $58 thousand combined potential value), the Department of the Navy Military Sealift Command (5 awards, $40 thousand), and the National Oceanic and Atmospheric Administration (2 awards, $8 thousand). The top work represents waste-oil, bilge-slops, and regulated-garbage removal from dredge vessels Essayons and Yaquina, foreign trash removal from USNS Emory S. Land, and boom and containment services for various Coast Guard units. Representative prime awards include a $92 thousand definitive contract from USACE (April 2025) for pump-off, transportation, and disposal of FY25 dredge-vessel slops through December 2025; a $60.7 thousand USACE Portland District purchase order (April 2024) for waste oil and bilge slops removal; and a $19.9 thousand Military Sealift Command purchase order (May 2026) for foreign trash removal from USNS Emory S. Land.
Activity has been modest and episodic: 2 awards in 2022, 5 in 2023, 4 in 2024, 3 in 2025, and 1 in the first five months of 2026. The combined potential value across all 27 awards is $385 thousand; obligated dollars ($540 thousand) exceed potential value, indicating contract closeouts and final billings on work already performed. In its subcontractor role under Vigor Marine LLC, Tidewater provides containment boom service, rental, launch assist, and small-boat support around naval vessels (USS John S McCain, USNS Chambers, USNS Guadalupe, USNS Henry J Kaiser) on four sub-awards dated between January 2024 and April 2025. Tidewater's capability footprint centers on NAICS 562998 (All Other Miscellaneous Waste Management Services), which dominates 16 of 27 awards, supplemented by ship repair and machinery maintenance work under PSC codes for non-nuclear ship repair and housekeeping waste services.
