About the company
Santorini Tanker LLC, doing business as C / O OSG Ship Management, operates as a prime contractor providing tanker time-charter and voyage-charter maritime transportation services exclusively to the Military Sealift Command (MSC) and the Air Force under full-and-open (unrestricted) federal procurements with no small-business set-aside designation. The company is a for-profit limited liability company and subsidiary of Overseas Shipholding Group Inc., headquartered in Tampa, Florida, operating under NAICS 483211 (Deep Sea Freight Transportation) and PSC code for marine charter services.
Santorini Tanker's federal footprint consists entirely of prime awards — 100% of 25 recent awards — concentrated on Naval fuel logistics. The Department of the Navy Military Sealift Command accounts for 24 awards worth $67.8 million combined potential value; the Department of the Air Force holds one award (a zero-dollar Voluntary Tanker Agreement indefinite delivery contract effective through December 31, 2032). All twenty-four MSC awards are purchase orders for tanker voyage charters or time charters delivering clean petroleum products (F76, JP5, JP8, JA1 fuels) aboard double-hull vessels with segregated ballast tanks and Naval Surface Warfare Center-approved equipment, performing across strategic maritime regions including the Mediterranean Sea, Arabian Gulf, Diego Garcia, and supporting naval and air operations globally. Representative work includes a $11.87 million 60-day tanker time charter for delivery to the Philippines (awarded June 18, 2026, completing August 25, 2026); a $5.26 million tanker voyage charter in the Mediterranean for JP5 and JA1 transport (awarded April 18, 2025); a $3.77 million 30-day time charter in the Mediterranean for F76 fuel (awarded September 17, 2025); and a $6.3 million 45-day time charter from the Arabian Gulf to the Mediterranean (awarded September 30, 2022).
Activity shows significant concentration in 2022 (7 awards) followed by decline through 2024 (1 award each in 2023 and 2024) and partial recovery in 2025 (3 awards) and 2026 (1 award to date). All $67.8 million in combined potential value has been obligated. The Air Force indefinite delivery contract for Voluntary Tanker Agreement contingency sealift services, awarded July 24, 2024 with an eight-year ceiling through 2032, establishes a framework allowing task-order issuance for clean-fuel ocean transportation on an as-needed basis to support global military logistics and contingency operations, though it carries a zero-dollar ceiling and has not yet generated obligated value. Santorini Tanker performs as a 100% prime contractor with no subcontract footprint in the source data, and does not compete under set-aside categories — all awards reflect unrestricted competition among all responsible sources.
