Interocean Systems, LLC

Interocean Systems, LLC (doing business as Interocean Systems Inc.), a subsidiary of Delmar Systems, Inc., manufactures specialized marine equipment—principally winch systems, cable-handling equipment, and oceanographic instrumentation—and sells these goods to federal agencies as a prime contractor, with occasional subcontractor roles on defense undersea systems programs. The vendor competes predominantly under total small business set-asides on direct-purchase orders from customer agencies; six of eleven prime awards carry total small business designations, while five recent prime purchases orders carry no set-aside.

Interocean operates from Santee, California, as a limited liability company subsidiary of a Louisiana-based Subchapter S corporation parent. The vendor's capability portfolio centers on custom-engineered marine equipment for oceanographic research, hydrologic instrumentation, and naval subsea operations. Representative prime work includes a $304,000 firm fixed-price purchase order from Naval Sea Systems Command (awarded January 23, 2026, due April 23, 2027) to design, manufacture, and deliver a subsea winch with attachable levelwinder system handling 3/8" Amsteel Blue line to 6,000 meters with 21,000-foot capacity and 4,000-pound load control; a $167,350 purchase order from the U.S. Geological Survey (awarded August 17, 2026) for a portable benthic sampling winch system with 3,500-pound load capacity and 750-meter fiber optic cable accommodation; and a $77,450 purchase order from the National Oceanic and Atmospheric Administration (awarded August 3, 2023) for a SERIED 388-ELW multi-purpose side scan winch. The vendor also produces oil-spill monitoring systems and specialized marine instrument accessories.

Customer concentration clusters around oceanographic and maritime research agencies. The top five customers by award count account for 81% of recent awards, led by the Department of the Navy's Naval Sea Systems Command and the Naval Information Warfare Systems Command (4 awards, $304 thousand combined potential value), the Department of the Interior's U.S. Geological Survey Office of Acquisitions and Grants (3 awards, $393 thousand), the Department of Homeland Security's U.S. Coast Guard (3 awards, $147 thousand), the National Oceanic and Atmospheric Administration (2 awards, $96 thousand), and the U.S. Army Corps of Engineers (1 award, $56 thousand). Awards per year have grown from one award in 2023 to four in both 2024 and 2025, with two awards in 2026 to date. Two awards totaling $471 thousand combined potential value reach completion inside the next twenty-four months, exposing recompete opportunity.

On the subcontractor side, Interocean performs under two named defense primes. Science Applications International Corporation drives the largest sub footprint—three sub awards for surface ship torpedo defense (SSTD) advanced development and engineering services, including nixie winch assemblies, slip rings, and system-engineering support across contracts dated February 15, 2024, May 13, 2024, and September 10, 2025. Pacmar Technologies LLC awarded a May 16, 2025 sub for materials supporting Manta Ray Phase 2 autonomous undersea vehicle development. Applied Physical Sciences Corp awarded a January 2, 2024 sub for a classified DARPA winch assembly. Service Contract Inventory reporting covers two subcontractor records (FY2022 and FY2025) at roughly 1.6 to 2.0 federal FTEs, indicating Interocean's sub engagement is equipment-delivery and materials-supply focused rather than labor-intensive services. The vendor sits on SeaPort-e (2 task orders) and the Undersea Weapons and Undersea Defensive Family of Systems Multiple Award Contract (1 task order).

The combined potential value across all sixteen awards is $1 million, though $6.3 million has been obligated across recent contract performance, indicating contract modifications and performance completions exceeding initial purchase order ceilings. This gap signals healthy order flow and customer retention across the marine and hydrologic instrumentation federal customer base.
