Program Overview Slides
The ENCON program responds to immediate needs for a high state of readiness while answering growing concerns for fuel shortages, increasing costs and environmental impact. ENCON reduces fuel consumption costs while increasing steaming hours and endurance range. Overall, for FY10, the Navy fleets realized a record 14.38% cost avoidance and gained 68,000 additional underway steaming hours. Some of these cost savings are returned to ships as incentives for program compliance. For example, the USS Bataan (LHD 5) was awarded $50,000 for its fuel reduction achievements. These slides provide an overview of the ENCON program that includes a more detailed discussion of the program's benefits, fuel-cost reduction success, incentive awards and how they are calculated, as well as the program's history and performance record. You will also learn what is involved in managing a ship's fuel consumption, the elements of the ENCON program, materials available to assist participation and the requirements for an effective ship program.
Tips: All Ships Slides
Changes in shipboard routine can measurably decrease fuel consumption and each 100kw reduction in power generation saves 8 gallons of fuel per hour. Discover the basic energy conservation strategies and methods that apply to all ships. This set of slides details the shipboard conditions required for a successful ENCON program implementation such as: aggressive training, economic plant alignment, development and monitoring of fuel curves, ship transit planning, equipment condition, zone inspections and enthusiastic involvement of all hands. Learn how fuel consumption is affected by various modes of ship operation, track selection, weather forecasts, course and speed changes, electric load reduction and resource management, ship's energy utilization, and maintenance.
Tips: Gas Turbine Slides
This session provides practical energy conservation tips for Gas Turbine propulsion ships. Different modes of operation are discussed including trail shaft, split plant, full power and single engine. Learn how to optimize energy efficiency and performance with tips on operating and maintaining gas turbines, controllable pitch propellers and Gas Turbine Generators. After providing general tips that affect the efficiency of gas turbine propulsion systems, this session gives details for improving performance of gas turbines including tips on the combustion air and intake system, water washing, bleed air, and more specific to gas turbines.
Tips: Diesel Engine Slides
This session provides practical energy conservation tips for Diesel Engine propulsion ships. Different modes of operation are discussed including trail shaft, split plant, full power and single engine. Learn how to optimize energy efficiency and performance with tips on operating and maintaining diesel engines and controllable pitch propellers, and Ship Service Diesel Generators. After providing general tips that affect the efficiency of diesel engine propulsion systems, this session gives details for improving performance of diesel engines by including tips on operational load profile, combustion analyzing and trending, combustion air system, blowers and turbochargers, auxiliary support systems and more specific to diesel engines.
Tips: Steam Ships Slides
This session addresses fuel consumption reduction for steam driven ships, comparing various plant alignments: typical vs. economic machinery alignments, steaming vs. modified main, and split vs. single boiler cross connect. Practical energy conservation tips are given for steam ships such as using only one forced draft blower per boiler for the most efficient boiler operation near its rated capacity. And when using one F.D. BLOWER per boiler, closing all drive turbine overload nozzle valves and discharge shutters on the secured F.D. BLOWER will result in the lowest fuel usage rate. Fuel savings of 4 to 7 percent can be realized just by proper adjustment of the air/fuel ratio and trimming excess combustion air. You will learn about other factors that influence fuel conservation including, among others: electric vs. steam-driven pumps, valve maintenance, light-off, burner management, superheater outlet temperature, selective use of boilers, SSTG operation, steam & water losses, heat loss, and maintenance of the propulsion plant.
