This opportunity involves a contract modification by the Department of the Navy, Military Sealift Command (MSC), to add specialized harbor tug services for a tow mission at the Naval Nuclear Power Training Unit (NPTU) in Charleston, SC. - Contract N3220524C4021 will be modified to include two fully-crewed U.S. Flag submarine-fendered harbor tugs - Tugs must have non-marking rubber fendering and specialized propulsion to protect naval vessels, especially submarines - The service is required for a period of up to 5 days, starting around August 2026 - Actual tow mission estimated to take 4-8 hours, but up to 5 days allowed for weather contingencies - The modification is out-of-scope, as the original contract covered only Norfolk, VA and surrounding waters - Only a limited number of providers, such as Moran Towing Corporation, can meet the specialized requirements - No specific product procurement; focus is on specialized tug services - No part numbers or purchase quantities for products; only service quantities (2 tugs) - The justification highlights the need for expanding contract coverage to support this unique mission
