ANALYSIS OF THE SINGLE FUEL CONCEPT WITHIN THE EUCOM AREA OF RESPONSIBILITY

Currently, U.S. Navy ships, with the exception of CVNs and submarines, utilize F-76 as their main fuel source and utilize JP-5 for aviation and support equipment. When planning for replenishment at sea, ships must plan to receive both F-76 and JP-5. Ships must also utilize separate storage and testing of the two fuels. The replenishment ships, which refuel the warships, are constrained by how much of each fuel type they can store. Being able to utilize a single fuel could simplify replenishment schedules. This research effort analyzes fuel supply and distribution capabilities during Phase II operations in the European theater when operating under the single fuel concept. This effort builds on two prior works: an unclassified study focused on the logistics benefit provided by the single fuel concept in the Pacific and a classified study (sanitized for this thesis) that explored the current logistics capability and capability gaps surrounding petroleum, oil and lubricant (POL) distribution. This work determines the potential impacts of switching to a single type of fuel (JP-5) and examines what kinds of policy changes and/or asset procurements may be needed to close those gaps. This study uses the NPS-developed Fuel Usage Study Extended Demonstration (FUSED) model to evaluate our capabilities to move fuel in theater using currently available assets operating under a single fuel concept (JP-5) and compares it with the performance with two fuels: JP-5 and F-76.Lieutenant Commander, United States NavyApproved for public release.

THE POTENTIAL BENEFITS OF ADOPTING THE SINGLE FUEL CONCEPT AT SEA IN THE BRAZILIAN NAVY

One of the Brazilian Navy’s critical challenges is monitoring and guarding its extensive Blue Amazon maritime area. Fuel management, which is highly complex and requires the expenditure of significant financial resources, is a fundamental factor for successfully fulfilling naval objectives. Currently, the Brazilian Navy uses diesel to fuel ships and aviation kerosene for aircraft. The purpose of this study is to examine the potential impacts of the Brazilian Navy adopting a single fuel concept (SFC) for its ships in the Blue Amazon protection zone. This concept means using kerosene to fuel both ships and aircraft. We used the Monte Carlo simulation methodology to model and observe the reduction in mission risk due to the SFC implementation in different scenarios. Our results demonstrate a substantial decrease in mission risk from the status quo to the SFC policy, increasing the effectiveness of Brazilian Navy patrol operations. We conclude that the employment of SFC improves the protection of the Blue Amazon’s maritime wealth.Capitao-Tenente, Brazilian NavyCapitão de Corveta, Brazilian NavyApproved for public release.

Fuel sharing in expeditionary operations

The article of record as published may be found at http://dx.doi.org/10.1016/j.cie.2018.09.040Article In PressExpeditionary units operate beyond the normal supply chain. We examine a situation in which expeditionary units are dispersed and moving forward to achieve some mission objective. The logistics decision must be made: should resources (fuel) be shared between those expeditionary units. Our criterion is mission risk, or the probability the expeditionary mission succeeds. Mission risk is modeled as a function of both logistics risk and operational risk. We present a model of fuel sharing which incorporates this balance of risks and we demonstrate the effectiveness of fuel sharing in an extended numerical example, based on historical data from the Ardennes campaign in WWII.Office of Naval Researc
