MDD provides Energy Conservation (ENCON) program support to the US Navy, specifically, the Operational Logistics Integration (OPLOG) Program and Military Sealift Command’s (MSC) ENCON Office. MDD has developed an energy management and planning process designed to measure fleet fuel usage, leverage energy saving technologies, and promote behavioral change within the US Navy to reduce Fleet fuel consumption.

The US Navy’s total yearly fuel usage is 38.8 Million (M) barrels with 15.5M barrels consumed by ships. Military Sealift Command (MSC) operates a fleet of ships that consume 6.2M barrels equaling 40% of the US Navy ship fuel consumption making it the largest US ship operator. Historically, US Navy and MSC ships were not designed or operated to save fuel. Therefore, there are significant opportunities for energy reduction. On average, MSC loses 2%-4% when buying fuel due to inaccurate fuel measurement totaling about $45M/Year. The T-AOE 6 class (4 Ships) consume more than 10% of MSC’s total yearly fuel and a single T-AOE 6 uses approximately $1M in fuel to cross the Pacific Ocean. A single T-AKE uses 14 - 20 Power Cords while on shore power costing between $141,000 and $200,000 per month.

MDD manages energy savings through an iterative energy management planning process to maximize ship efficiency. Energy management includes base lining ship energy usage, developing conservation measures, implementing solutions, validating systems, equipment, and technology, collaborating within the Fleet, and providing guidance to save energy under all operating conditions. A successful management process clearly identifies the types and costs of energy use, promotes an understanding of how energy is used and where to focus reduction efforts, and explores cost-effective ways of using energy through improved operational techniques, new equipment, new processes, or new technology. MDD is involved in implementing the following energy management and conservation efforts:
