About this IDV

Thrustmaster of Texas, Inc., a Houston-based small business manufacturer of commercial marine propulsion systems, holds a Total Small Business single-award Indefinite Delivery Contract with the U.S. Coast Guard valued at $12.79 million for the maintenance, overhaul, and technical support services of Ulstein Aquamaster Model 1350H Z-drive thrusters installed on the Coast Guard's 175 WLM (Waterline Meter) class inland buoy tenders. The contract was awarded on December 23, 2021, with an ultimate completion date of December 22, 2026, and includes a fourth option year exercised from December 23, 2025, through December 22, 2026. The contract encompasses comprehensive thruster system services including inspection, repair, overhaul, parts replacement, and on-site technical representative support to ensure operational readiness of the Coast Guard's buoy tender fleet, which conducts maritime security, law enforcement, and search and rescue missions.

The contract has generated numerous delivery orders totaling several million dollars in task orders since its inception, with individual orders ranging from component supply purchases (seal prop kits, clutches, and seal assemblies) valued between $6,800 and $824,905 to comprehensive vessel thruster system repairs and installations. Place of performance is primarily Houston, Texas 77041, with some delivery orders performed at various Coast Guard vessel locations including Baltimore, Maryland; Houma, Louisiana; and other ports. All delivery orders are issued on a firm fixed-price basis without small business set-asides, reflecting the contractor's established capability under the primary IDV. The contract supports the Coast Guard's Service Life Extension Program for the 175-foot inland buoy tender fleet by providing critical propulsion system maintenance, technical expertise, and specialized marine equipment necessary to sustain vessel operational effectiveness throughout their extended service lives.
