Oceaneering International Inc.

Oceaneering International Inc.'s Marine Services Division operates as a prime contractor (52% of awards) and subcontractor (48% of awards) delivering submarine safety hardware, payload tube platforms, valve and actuator assemblies, hull-mechanical-electrical systems engineering, and specialized repair services to the U.S. Navy. The division, headquartered in Chesapeake, Virginia, is a subsidiary of Oceaneering International Inc., a global engineering services company, and competes on full-and-open Navy contracts without set-aside designations.

The Marine Services Division's customer base is almost entirely the Department of the Navy. Naval Sea Systems Command (NAVSEA) dominates the portfolio, accounting for 276 awards (98% of all awards by count) with $15.3 billion in combined potential value. Naval Supply Systems Command places 33 awards worth $178.4 million, primarily for component-level valve and actuator repairs. The Office of Naval Research has issued one delivery order valued at $28.3 million for electromagnetic maneuver warfare scientific and engineering support under Seaport-NXG. The concentration is extreme — NAVSEA captures the dollar majority across submarine and fleet modernization programs, while smaller Naval Supply orders drive high transactional volume in component repair work.

The division holds multiple IDIQ vehicles with NAVSEA and NAVSUP. The largest active vehicles include a $762.4 million multiple-award Indefinite Delivery Contract for "OPW - LOT 1 Critical Systems Engineering" (CNO Availabilities for Fast Attack Submarines) awarded September 2, 2025, a $172 million IDIQ for Submarine Corporate Component Repairs Program awarded August 11, 2025, a $33.13 million single-award contract for Virginia Class Submarine Racetrack components awarded June 9, 2025, and an $88.1 million multiple-award vehicle for Navy Submarine Preservation and Repair awarded April 1, 2025. The division also holds positions on Seaport Next Generation (Seaport-NXG) and other Navy-managed multiple-award vehicles. Recent representative prime awards include a $12.62 million delivery order for macro/micro crane and advanced mooring systems equipment under Seaport-NXG (September 2025), a $6.52 million cost-plus-fixed-fee order for New Hampshire submarine work package SUBSAFE support (September 2025), a $2.33 million SUBSAFE fuel oil tank repair delivery order for USS Maryland at Kings Bay Base (December 2025), and a $2.24 million firm-fixed-price definitive contract for complete hydraulic power unit assemblies (September 2024).

Award volume grew significantly from 41 in 2022 to 209 in 2024, though 2025 and early 2026 show only 26 total awards in the source, reflecting the multi-year task-order structure of the underlying IDIQ vehicles. Eleven awards carrying combined potential value of $244.1 million reach ultimate completion within the next twenty-four months, representing material recompete exposure in submarine safety hardware, payload integration, and hull systems engineering work.

The division operates as a deep submariner in the Navy's supply base. In its subcontractor role, it delivers valve assembly components, structural repairs, electrical system support, and long-lead-time materials to prime contractors Electric Boat Corporation and Huntington Ingalls Inc. on Los Angeles-class and Virginia-class submarine new construction, overhaul, and modernization programs. Across roughly 60 named sub-awards captured in the source, scope includes USS Columbus, USS Boise, USS Connecticut, and other named submarine projects covering missile tube work, valve and actuator restoration, electrical distribution and radio systems, periscope and snorkel maintenance, and specialized welding and fabrication support. The subcontractor pattern reflects a core manufacturing and repair capability that both primes — who execute integration and fleet-level work — require for component-level delivery.

Service Contract Inventory reporting for FY2022–FY2024 shows $70.3 million in SCI-reportable invoiced revenue across 225.1 FTEs (prime records only). That places median government-paid rates at $142.98/hour, with senior labor through $196.25/hour. The division self-performed all SCI-reportable hours with zero subcontractor labor recorded across those prime contracts, indicating an internal-delivery model for the majority of its Navy engineering and technical services work. The FTE trajectory grew from 39.3 in FY2022 to 96.3 in FY2023, then contracted slightly to 89.5 in FY2024, tracking task-order demand fluctuations within the submarine fleet modernization cycle.

Oceaneering's portfolio concentration on NAVSEA underwater platforms, combined with the division's established seat on multiple billion-dollar submarine support IDIQs and demonstrated capability in SUBSAFE program work, positions it as a sustained supplier for the Navy's 21st-century submarine fleet readiness. The pipeline reflects not rapid growth but deep, recurring engagement across maintenance, overhaul, and modernization sustainment spanning Los Angeles and Virginia-class platforms.
