About the company
Seatrium Repairs & Upgrades Pte. LTD., a Singapore-based marine and offshore engineering company, operates as a prime contractor delivering ship repair, maintenance, overhaul, and upgrade services exclusively to the Department of the Navy, with all work performed at its facility in Singapore under firm fixed-price terms with no set-aside designation. The vendor is a child entity of the National Cancer Centre Of Singapore PTE LTD and competes in the unrestricted market across 155 federal awards totaling $640.9 million in combined potential value.
Seatrium's customer concentration is absolute: 116 awards valued at $611.4 million flow through the Department of the Navy Military Sealift Command, representing 99% of recent award volume and nearly all dollars. The remaining four customer Navy commands — Naval Supply Systems Command (7 awards, $14.1 million), Naval Sea Systems Command (5 awards, $15.4 million), United States Pacific Fleet Forces (3 awards), and the broader Department of the Navy umbrella (22 awards) — account for the remaining fraction. This is a single-customer vendor with Navy MSC as its sole meaningful customer.
Capability delivery centers on regular overhauls (ROH), mid-term availability (MTA) maintenance, and maintenance-and-alterations work on non-combatant Navy auxiliary vessels in the Oiler and Ammunition Ship classes. Representative work includes a $24.8 million firm fixed-price overhaul of USNS Yukon (T-AO 202, ultimate completion August 2026), a $24.5 million overhaul of USNS Rappahannock (T-AO 204, June 2026), a $19.8 million modification incorporating 14 change orders for USNS Tippecanoe (T-AO 199, May 2026), a $25.4 million overhaul of USNS John Ericsson (July 2025), and a $21.1 million overhaul of USNS Carl Brashear (T-AKE 07, August 2024).
The vendor holds two foundational Indefinite Delivery vehicles with MSC: Basic Ordering Agreement N4034521G0002 (18 task orders, $221.7 million combined potential value, running January 1, 2021 through December 31, 2025) and Basic Ordering Agreement N4034515G0002 (37 task orders, $143.4 million combined potential value). These are single-award MSRAs through which the vast majority of task orders flow. A third vehicle, Indefinite Delivery Contract N4034509G0002, supports 13 task orders valued at $15.4 million.
Activity has contracted sharply in recent years — nine awards in 2022, declining to five in 2023, two in 2024, five in 2025, and one through March 2026. One award valued at $26.9 million faces ultimate completion within the next twenty-four months, creating a narrow recompete window. The vendor has no subcontract footprint; all 155 awards are prime awards. Category concentration is extreme: 140 of 155 awards fall under NAICS 327211 (Ship Building and Repairing), with 125 task orders classified under PSC Non-Nuclear Ship Repair (West).
