Mobil Oil Mariana Islands, Inc.

Mobil Oil Mariana Islands, Inc., a division of ExxonMobil, supplies diesel fuel, marine bunker fuel, and related petroleum products to the Department of Defense as a prime contractor across a single-award indefinite delivery contract with the Defense Logistics Agency Energy, competing on the open market without set-aside designation. Based in Saipan, Commonwealth of the Northern Mariana Islands, the company operates as a fuel logistics provider for U.S. Navy vessels, Military Sealift Command assets, and other DoD maritime platforms operating throughout the Pacific theater, delivering fuel via barge, truck, and pipeline methods.

Mobil Oil Mariana Islands has a highly concentrated customer footprint. The Defense Logistics Agency Energy accounts for 83 of 84 recent prime awards (99% of all awards by count) and $118.2 million in combined potential value; the Department of the Air Force Pacific Air Forces placed a single $36 thousand Jet A1 fuel services order in 2021. The vendor competes entirely in full-and-open procurements with no small business set-asides across its portfolio. Its federal work flows through two parent indefinite delivery contracts: the larger SPE60016D0358 vehicle, which carries a $14.3 million ceiling running through September 30, 2026, and SPE60521D1010, a smaller secondary IDV. Seventy-four delivery orders have been issued under SPE60016D0358 (combined potential value $30.6 million) and twenty-one under SPE60521D1010 ($2.1 million), with individual orders typically valued between $36 thousand and $361 thousand and completion periods of one to six months.

Activity accelerated in 2022–2023, with ten awards in 2022 and fifteen in 2023, then contracted to six in 2024 and four in 2025 before rebounding to twelve in 2026 through April. The bulk of Mobil Oil Mariana Islands' recent work falls under the Fuel and Energy Program for Combat Equipment (FEPEC) Ship's Bunker program, procuring commercial marine gas oil, fuel oil grades RME-180 and RMG-380, very low sulfur fuel oil, and diesel fuel for vessel bunker operations. Representative awards include a $2.68 million purchase order for Navy vessel fuel awarded September 2024, a $3.07 million firm fixed-price purchase order for Navy ship fuel issued February 2023, and a $2.65 million purchase order for Navy vessel fuel awarded June 2023. All pricing uses firm fixed-price or fixed-price-with-economic-price-adjustment structures, with performance consistently occurring in Saipan, CNMI. The vendor's role is geographically specialized — it serves as the exclusive fuel supplier for DoD maritime operations in the Northern Mariana Islands region under its primary IDV, demonstrating deep operational rootedness in that theater rather than broader federal market presence.
