This opportunity concerns a Department of the Navy request for an out-of-scope contract modification to add a specialized harbor tug service for a tow mission at the Naval Nuclear Power Training Unit (NPTU) in Charleston, SC. - The modification is to contract N3220525C4019, managed by Military Sealift Command (MSC), Ship Charter Contracts Division. - The service involves providing a fully-crewed, U.S. Flag, submarine-fendered harbor tug for undocking and river transit support of MTS 626. - The mission is estimated to last 5-7 days, including travel, and is scheduled for around August 2026. - The requirement is outside the contract's original geographic scope (King's Bay, GA/Mayport, FL), necessitating this justification. - Only a limited number of providers have the required specialized tugs, including Moran Towing Corporation, Thames Towboat Company, and Alpha Marine Services. - No specific products, part numbers, or OEMs are mentioned, as this is a service procurement. - The justification notes that no other suitable commercial sources are available for this mission.

Description
