California Marine Cleaning, Inc.

California Marine Cleaning, Inc., a for-profit Subchapter S corporation based in San Diego, California, delivers specialized maritime tank cleaning, hazardous waste removal, and ship maintenance services to the U.S. Navy, Coast Guard, and defense logistics agencies as both a prime contractor (53% of recent awards) and subcontractor (47%), competing predominantly under total small business set-asides on individual purchase orders and task orders under Navy indefinite delivery contracts.

The company's customer concentration is heavily skewed toward Navy shipyard and fleet operations. The top three customers by award count and potential value rank nearly identically: Naval Sea Systems Command dominates with 356 awards valued at $3.5 million combined potential value, followed by the Defense Logistics Agency Disposition Services (40 awards, $2.6 million), and the U.S. Coast Guard (21 awards, $141 thousand). Naval Sea Systems Command represents the overwhelming majority of California Marine Cleaning's dollar exposure and operational focus. The company has worked with thirteen distinct federal agencies overall, but Navy-affiliated customers account for 94% of recent award volume. Recent prime-awarded work includes a $23,605 total small business set-aside purchase order from Naval Sea Systems Command for USS Anchorage (LPD-23) CIS tank cleaning in San Diego (awarded March 3, 2026, performance through April 24, 2026); a $92,750 total small business set-aside purchase order for sanitary tank cleaning at Naval Base Point Loma (awarded July 2, 2024); and a $28,700 order from Naval Sea Systems Command for emptying, cleaning, offloading, and disposing of fuel oil and hydraulic oil tanks aboard USS Pinckney (DDG-91) (awarded March 25, 2024). The company also holds a multi-year indefinite delivery contract with Naval Sea Systems Command valued up to $1,676,233.28 for submarine tank cleaning services in the Pacific region.

California Marine Cleaning operates across five indefinite delivery contracts as the primary parent vehicles. The largest is Indefinite Delivery Contract N6338796D3145 with 221 task orders, followed by N0002418D4325 with 78 task orders, SP440002D0022 with 25 task orders ($221 thousand combined potential value), a Complex and Non-Complex Maintenance vehicle for Surface Combatant and Amphibious Class Ships at San Diego with 21 task orders, and N0002416D4416 with 16 task orders. These vehicles anchor the company's recurring Navy shipyard and fleet work.

Activity has grown rapidly in recent years — 2 awards in 2022, 52 in 2023, 150 in 2024, and 189 in 2025 — though the source's combined potential value figure of $7.7 million sits well below the $27.2 million in dollars obligated (352% ratio), indicating that invoiced performance and contract modifications have substantially exceeded ceiling values recorded at award. Award distribution by NAICS shows the company's core capabilities: Ship Building and Repairing (434 awards, the dominant classification), Hazardous Waste Collection (149 awards), and Hazardous Waste Treatment and Disposal (63 awards). Top PSC codes align with this profile: Environmental Systems Protection—Environmental Remediation (154 awards), Housekeeping—Trash/Garbage Collection (105 awards), and Non-Nuclear Ship Repair (West) (52 awards).

California Marine Cleaning maintains a regional subsidiary structure: Atlantic Marine Cleaning, LLC; Washington Marine Cleaning LLC; Mid-Atlantic Marine Cleaning LLC; and Hawaii Marine Cleaning LLC, each organized as a limited liability company. These subsidiaries position the company to serve Navy and Coast Guard facilities across the continental United States, Hawaii, and Atlantic-region shipyards.

The company's subcontractor footprint is dominated by BAE Systems Maritime Solutions San Diego Inc. and BAE Systems Maritime Solutions Norfolk Inc., which collectively account for the vast majority of California Marine Cleaning's sub awards. Subcontract work involves tank cleaning, flushing, and hazardous-materials disposal services in support of Dry Selected Restricted Availability (DSRA), Selected Restricted Availability (SRA), and Planned Incremental Availability (PIA) maintenance events aboard amphibious and guided-missile vessels. Smaller subcontracting relationships include Prism Maritime, Inc. for air and missile defense capability installation work involving piping system cleaning and flushing, and Delphinus Engineering, Inc. and BAE Systems Jacksonville Ship Repair LLC for specialized ship repair support. The subcontractor role has grown in 2025 and early 2026, with the company providing direct labor and materials for tank cleaning, waste disposal, and system maintenance across multiple carrier and surface-combatant availabilities.
