About Overseas Shipholding Group Inc.

Written by GovTribe AI ·

Overseas Shipholding Group Inc. (OSG) is a prominent maritime transportation company specializing in energy and petroleum product logistics, with a significant focus on providing tanker charter services to the U.S. federal government. The company primarily serves the Department of Defense, specifically the Military Sealift Command, through its various subsidiaries like Overseas Sun Coast LLC, Santorini Tanker LLC, and Mykonos Tanker LLC. OSG operates a fleet of double-hull tankers capable of transporting petroleum products, jet fuels, and other clean cargo across global maritime regions including the Mediterranean, Middle East, Far East, and Atlantic theaters.

Through federal contract awards, OSG has consistently provided time charter and voyage charter services for transporting petroleum products to military installations worldwide. The company's contracts, predominantly awarded by the Military Sealift Command, involve chartering vessels to transport substantial quantities of fuel types such as JP5, JP8, F76, and JA1, ranging from 130,000 to 280,000 barrels per shipment. These contracts typically involve maritime transportation between strategic locations like Greece, Qatar, Spain, the United Kingdom, Bahrain, Diego Garcia, and various Mediterranean and Middle Eastern ports. All contract awards have been unrestricted, with no specific small business set-aside designations, and have been executed as firm fixed-price purchase orders or definitive contracts with performance periods ranging from 25 to 90 days.

OSG has recently expanded its federal grant portfolio to focus on innovative carbon transportation and capture technologies. The company has received cooperative agreements from the Department of Energy's Office of Fossil Energy and Carbon Management, including a $3,152,650 award for the "Carbon Ocean and Storage Transport 20" (COAST20) project to demonstrate marine transport systems for captured carbon dioxide. Another grant of $401,261 supports research on the Tampa Regional Intermodal Carbon Hub, exploring technological feasibility for carbon capture and transportation innovations. Additionally, a Maritime Administration cooperative agreement focuses on evaluating cost-effective carbon capture integration for maritime vessels.

While the provided documentation does not explicitly detail specific Indefinite Delivery/Indefinite Quantity (IDV) contracts, the contract awards consistently reference the N103/N321B multiple award contract vehicle administered by the Military Sealift Command. This suggests OSG operates under a pre-existing contract framework that allows for repeated task order awards for tanker charter services. The contract vehicle appears to provide flexibility for the Military Sealift Command to rapidly procure maritime transportation services across different global regions, with OSG consistently demonstrating capability to meet complex fuel transportation requirements for naval operations through its modern, double-hull tanker fleet.
