About ST Engineering Marine LTD.
ST Engineering Marine LTD, doing business as ST Marine LTD, is a Singapore-based marine defense contractor that performs naval ship maintenance, repair, overhaul, and modernization services for the U.S. Navy as a prime contractor (95% of awards), operating entirely on a full-and-open, non-set-aside basis. The vendor holds a Master Ship Repair Agreement IDIQ with U.S. Pacific Fleet Forces running through May 2026, which anchors the bulk of its task-order work, and performs all work at its Singapore facility.
ST Engineering Marine operates with heavy customer concentration in the Department of the Navy, where 90% of recent awards track to four Navy sub-offices: Military Sealift Command (9 awards, $35.9 million combined potential value), Naval Supply Systems Command (3 awards, $5.3 million), U.S. Fleet Forces Command Atlantic (1 award, $11 million), and U.S. Pacific Fleet Forces (2 awards). The Navy represents the entirety of the vendor's customer base. Top parent vehicles are two Basic Ordering Agreements (BOAs) — N4034517G0002 (5 task orders, $16.5 million combined potential value) and N4034521G0004 (5 task orders, $24.8 million combined potential value) — plus the Pacific Fleet MSRA IDIQ (N6804700G0003). The vendor's NAICS footprint is dominated by Ship Building and Repairing (18 awards), with PSC codes concentrating on non-nuclear ship repair.
Representative recent work includes a $10.96 million firm fixed-price definitive contract awarded February 27, 2026 by U.S. Fleet Forces Command (Atlantic Fleet) for regular overhaul and dry-dock availability of USNS SALVOR (T-ARS 52), completion August 2, 2026; a $5.13 million delivery order from Military Sealift Command (September 2023) for maintenance, repair, and overhaul of USNS PUERTO RICO; a $4.96 million delivery order from Naval Supply Systems Command (December 2022) for maintenance and alteration of USNS BRUNSWICK; and a $9.11 million delivery order from Military Sealift Command (December 2022) for regular overhaul of USNS PUERTO RICO. Activity declined after 2022 — from 4 awards in 2022 to 1 award each in 2023, 2025, and 2026 — and the recompete cliff shows only one award (the February 2026 SALVOR contract) reaching completion inside the next twenty-four months, worth $11 million. The vendor subcontracts minimally (one sub award identified: October 2025 sub-award under Crowley Government Services for vessel operation and maintenance). Combined obligated dollars ($59.6 million) exceed combined potential value ($52.2 million), indicating work completion ahead of ceiling in prior periods.
