Yokohama Dock Co., LTD.

Yokohama Engineering Works, LTD., a for-profit maritime services company based in Yokohama, Japan, operates as a prime contractor delivering watercraft repair, maintenance, modernization, and service life extension services to the Department of Defense, competing entirely under full and open (non-set-aside) awards. The vendor holds two primary indefinite-delivery contracts with the Army's TACOM Life Cycle Management Command valued at $211.1 million (Zone 2, through July 2031) and $69.8 million (Zone 3 Pier Side, through July 2031), plus a Navy Installations Command Basic Ordering Agreement through February 2028. Across 150 federal awards spanning 2002 to August 2026, Yokohama Engineering Works has accumulated $894.2 million in combined potential value with $222.9 million obligated to date; the company performs 97% of its work as a prime contractor.

The vendor's capability footprint is narrowly specialized in maritime asset sustainment. Primary NAICS codes center on Ship Building and Repairing (113 awards), with secondary exposure in Other Support Activities for Water Transportation (8 awards). Concrete work includes drydocking, cleaning, painting, repairs, and service life extension programs for Army Landing Craft Utility vessels (LCU 2009, LCU 2020, LCU 2022, LCU 2027), Modular Warping Tugs (MWT 1, 2, 5, 6, 11, 13, 16), Causeway Ferries, Small Tugs, and Navy vessels including sonar barges and skimmer boats. Representative recent delivery orders span $26.0 million (LCU 2020 specifications work, awarded September 2025, PEO CSCSS, completion February 2028), $41.8 million (LCU 2022 and LCU 2027 service life extension program, awarded August 2023, PEO CSCSS, completion December 2026), $6.0 million (MWT-01 Service Life Extension Program, awarded September 2022, completion June 2024), and multiple $1.3 million to $2.0 million orders for cyclic maintenance and programmed repairs.

Customer concentration is extreme and Army-anchored. The Department of the Army Materiel Command TACOM Life Cycle Management Command dominates both volume and value, holding 35 awards with $745.5 million combined potential value (84% of the vendor's total portfolio). The Department of the Army's PEO Combat Support and Combat Service Support contributes four awards worth $95.4 million (mostly large service life extension programs). Together, Army customers account for 99% of combined potential value across the top five funding agencies. Navy work—Naval Sea Systems Command (37 awards, $9.3 million), Military Sealift Command (17 awards, $1.5 million), and Navy Installations Command (15 awards, $7.1 million)—represents secondary, low-dollar volume activity supplementing the core Army watercraft sustainment mission.

Yokohama Engineering Works places the overwhelming majority of its work under two parent vehicles: the Army Watercraft Sustainment Maintenance Zone 2 IDIQ (16 task orders, $116.6 million combined potential value) and a Navy Basic Ordering Agreement N6264914G0005 (24 task orders, $43.9 million). The Zone 2 IDIQ, renewed January 30, 2026, carries a $211.1 million ceiling through July 2031 and authorizes pier-side sustainment maintenance, repairs, certifications, inspections, modifications, and modernization for Army watercraft globally with emphasis on Asia-Pacific operations. The parallel Zone 3 Pier Side IDIQ carries $69.8 million through July 2031. All work is firm fixed price with place of performance in Japan, leveraging the vendor's geographic positioning at Yokohama North Dock to service U.S. military assets throughout the Asia-Pacific region.

Activity remains steady but low-volume in absolute award count: six awards in 2023, ten in 2024, six in 2025, and eight in 2026 year-to-date. However, individual delivery orders carry substantial dollar magnitude—the $211.1 million and $69.8 million IDIQ ceilings mask high per-task value. Three awards totaling $95.4 million in combined potential value reach ultimate completion within the next twenty-four months (the LCU 2020 specifications work, two additional large orders), presenting recompete opportunity for competitors and execution risk for the vendor. In its limited subcontractor role (3% of awards), Yokohama Engineering Works performs marine handling system sustainment, vessel operation and maintenance support, and barrier refurbishment work under primes Marine Ventures International, Inc., Crowley Government Services, Inc., and Oceanetics Inc.

Yokohama Engineering Works competes entirely outside set-aside categories. The vendor operates exclusively under full and open competition across all funding agencies and parent vehicles, competing on capability and geographic advantage rather than small-business or disadvantaged-business designations. Federal registration dates to December 2006, establishing a twenty-year track record as a stable Asia-Pacific maritime repair base for Army and Navy watercraft sustainment requirements.
