About this IDV

Seaward Marine Services, LLC, a foreign-owned maritime services contractor based in Norfolk, Virginia, was awarded a single-award Indefinite Delivery/Indefinite Quantity (IDIQ) contract by the Military Sealift Command (MSC) on August 10, 2021, with a ceiling value of $24,090,612 and ultimate completion date of August 9, 2026. The contract encompasses underwater hull survey, cleaning, and inspection services, as well as associated work including cofferdam installation and removal, diving support, and specialized vessel maintenance activities. The original solicitation, posted as a pre-solicitation notice on May 31, 2019, indicated the government's intent to procure comprehensive ship husbandry and maintenance support services without a set-aside designation. Under this IDIQ vehicle, the Military Sealift Command has issued numerous firm fixed-price delivery orders ranging from approximately $21,500 to $3.7 million, with performance locations spanning domestic ports (Norfolk, San Diego, Charleston, Jacksonville, and others) and international locations (Bahrain, Singapore, Oman, Ecuador, Philippines, South Korea, Thailand, Guam, and Italy).

The delivery orders executed under this IDIQ contract demonstrate MSC's utilization of Seaward Marine Services' specialized maritime maintenance capabilities to support global naval logistics operations across diverse vessel classes, including auxiliary oilers, dry cargo/ammunition ships, hospital ships, and replenishment vessels. Representative task orders include underwater hull cleaning and inspection for vessels such as USNS Fall River, USNS Mercy, and USNS Comfort; cofferdam services for sea chest repairs and ballast overboard applications on multiple ships; and underwater inspection in lieu of drydocking (UWILD) services. The work has consistently been performed on a firm fixed-price basis with completion dates typically ranging from one to six months from award date, reflecting the urgent and flexible nature of fleet maintenance requirements. Seaward Marine Services' execution of this contract underscores MSC's reliance on specialized contractors to maintain operational readiness of the Navy's strategic sealift and auxiliary vessel fleet while supporting global deployment schedules and maintenance cycles.
