About Unithai Shipyard & Engineering LIMITED - Branch

Written by GovTribe AI ·

Unithai Shipyard & Engineering LIMITED - Branch, a Thailand-based foreign-owned subsidiary, provides ship repair, maintenance, and logistics support services exclusively to the Department of the Navy as a prime contractor, operating without set-aside designations on a single-award Basic Ordering Agreement (BOA) established in February 2024. The vendor is a division of Unithai Shipyard & Engineering LIMITED, a Thailand-headquartered for-profit organization.

Unithai's federal footprint is highly concentrated in military maritime maintenance. The vendor holds two active BOAs with the Navy — a February 2024 BOA valued at a $0 ceiling (placeholder) with cumulative obligations exceeding $100 million, and an earlier August 2019 BOA — which have generated 35 task orders carrying $97.7 million in combined potential value. The vendor operates from shipyard facilities in Thailand and serves exclusively Navy customers: Military Sealift Command (MSC) issues 41 awards totaling $126 million of potential value; U.S. Pacific Fleet Forces issues 4 awards worth $19.2 million; and U.S. Fleet Forces Command (Atlantic) issues 1 award worth $9 million. This concentration spans 100% of the vendor's recent award portfolio across three Navy components.

Unithai's concrete capabilities center on voyage repair, mid-term availability (MTA) maintenance, regular overhaul with underwater hull inspection, engine repairs, tank cleaning, and urgent repair work on Navy sealift and logistics vessels operating globally. Representative recent prime work includes a $23.6 million lay berth repair delivery order (MSC, September 2025), a $12.3 million definitive contract for regular overhaul and underwater hull inspection of USS John L. Canley (MSC, April 2026), an $8.996 million USS Miguel Keith mid-term availability delivery order (Atlantic Fleet, September 2025), a $10.985 million USNS Cesar Chavez mid-term availability delivery order (Pacific Fleet Forces, November 2024), a $15.309 million USNS Big Horn mid-term availability delivery order (MSC, February 2023), and a $9.623 million USS Miguel Keith regular overhaul delivery order (MSC, August 2022). All work carries firm fixed-price terms with no set-asides; the vendor competes full-and-open for all Navy maritime-maintenance requirements.

Activity shows a decline from peak historical volumes. The vendor recorded four awards in 2022, ten in 2023, eight in 2024, seven in 2025, and one in 2026 year to date. Over 96% of combined potential value ($148.1 million of $154.3 million) has already been obligated, reflecting that most awards are executing against the two BOAs. Only one award ($12.3 million) reaches ultimate completion within the next twenty-four months, presenting a significant recompete exposure as the February 2024 BOA approaches its January 31, 2029 expiration and earlier BOA work cycles through completion. The vendor's NAICS footprint is dominated by Ship Building and Repairing (45 awards), with one award in Commercial and Industrial Machinery and Equipment Repair and Maintenance; PSC coding splits between Non-Nuclear Ship Repair (West) for 43 awards and Non-Nuclear Ship Repair (East) for 2 awards. Unithai operates as a 100% prime contractor with no subcontractor relationships in the federal data and no sub-award activity.
