- Description
- The Naval Sea System Command (NAVSEA) is hereby issuing a Request for Information (RFI) on behalf of PMS 320 (the Electric Ships Office), seeking information from all potential sources who may be interested in supplying a gas turbine generator set in the 4.0 to 5.0 Megawatt power range for use on Naval vessels. The Navy is currently seeking gas turbine-generator sets in this power range that make use of existing or modified engines. If modifications to existing engines are required, the modifications must be capable of being designed, implemented, tested, and qualified by the Year 2015 timeframe. DESCRIPTION: The focus of this request is to gain knowledge of the current and projected state of the art for marine gas turbine-generator sets in the power range and with the performance capabilities of interest that can also be delivered ready for use no later than Year 2015. This Section provides a set of performance characteristics that meet the needs of the notional system. 1. The turbine-generator set continuous rated output power is to be in the range of 4.0 to 5.0 Megawatt electrical for use on Naval vessels. Continuous rated output power shall be flat rated. The turbine-generator set shall provide output power at 4160 VAC, 60 Hz, and at 0.8 Power Factor lagging. Gas turbine power rating shall be based on a Hot Section Repair Interval of 2,000 hours when operating at rated power, at rated speed and Navy Standard Day rating conditions as follows: Inlet air temperature: 100 degrees F Relative Humidity: 40%, Inlet barometer air pressure dry: 29.92 inches Hg Inlet air system loss: 4 inches H20 Exhaust system loss: 6 inches H20 Fuel Lower Heating Value: 18,400 Btu/lb Sea water cooling inlet temperature: 95 degrees F For purposes of this request, respondents may assume that turbine-generator sets will need to meet the qualification requirements of American Bureau of Shipbuilding Naval Vessel Rules for a high usage application or similar military standards. 2. Operate on all of the following fuels: Military Specification, MIL-F-16884 Naval Distillate (NATO F-76). Military Specification, MIL-T-5624 Aviation Turbine Fuel, Grade JP-5 (NATO F-44). The engine shall also be capable of operating on Marine Gas Oil to ASTM D6985, when F-76 and F-44 are not available. 3. Package critical dimensions (including gas turbine, generator, lube system, fuel system, start system, acoustic enclosure, sub base with resilient mounting system, control system, and other equipment necessary to provide a complete functional set) shall not exceed the following dimensions: Length: 382 inches Width: 118 inches Height: 161 inches 4. The total weight of the skid-mounted turbine-generator set shall be less than 115,000 pounds. 5. Capable of providing electric power quality at the system-user equipment interface in accordance with MIL-STD-1399 upon sudden application of 80% of rated load in one step, as well as upon removal of 70% load in one step from the 80% load initially applied. 6. Capable of providing 2.5 lb/sec compressed air at 75 psig across the entire power range. Reduced power capability when providing compressed air is acceptable, but identification of the continuous rated output power while in this state shall be provided. 7. Capable of conducting a minimum of four consecutive dark ship starts without the supply of external power. 8. Capable of meeting the shock requirements of MIL-S-901D for Grade A, Class II Hull Mounted Machinery. 9. Meet the following standard operating conditions. Inlet air temperature: -40 to 125 degrees F Inlet barometer air pressure dry: 12.6 to 15.7 psia Seawater cooling inlet temperature: 28 to 95 degrees F Relative Humidity: 0 to 100% Inlet air system loss: 0 to 12 inches H2O Exhaust system loss: 0 to 20 inches H2O Engine room temperature: 20 to 125 degrees F 10. Ensure proper operation (ability to perform all normal operations at maximum continuous performance ratings in accordance with the performance and safety requirements for each component/system without loss of lubrication and with no loss of liquids) under the following inclination conditions (conditions not considered additive): List: +/- 15 degrees (static condition) Roll: +/- 45 degrees (dynamic condition) Trim (Normal): +/- 5 degrees (static condition) Pitch: +/- 15 degrees (dynamic condition) RESPONSES: Responses should be limited to 15 pages or less (not including any drawings or sketches). A detailed proposal is not requested. Provide as much of the following technical data as practical within the time constraints of this inquiry. The following information is requested (please indicate if the information is an estimate or based on actual data): 1. Description of the gas turbine engine, its population base and applications, including an indication of the degree to which it is marinized and/or militarized. Identify any applications where the engine has been used in a turbine- generator set. 2. Description of any proposed modifications to the engine to meet the requirements identified herein, including a discussion of the technical maturity level of the proposed modifications and the schedule and development activities to maturing and incorporating these modifications into the proposed engine. 3. Define the development status of the turbine-generator set and identify the steps necessary to bring the set to a fully marinized and militarized standard, including shock and vibration qualification and endurance testing. 4. Provide the development timeline, including estimated time to modify or develop the turbine-generator set assuming a start of 1 February 2013 and the delivery of a qualified set by the Fiscal Year 2015 timeframe. 5. Provide available generator set transient response capability to step load changes. 6. Provide estimated specific fuel consumption (SFC) (lb/kW-hour) throughout the power range for both the turbine-generator set, with and without provision of compressed air. SFC shall be provided in tabular form at Standard Navy Day rating condition. 7. Provide rated power capability for both the engine and complete turbine-generator set, at Standard Navy Day rating conditions, with and without provision of compressed air. If other rating methodologies were used, provide the rating and the methodology (e.g. ISO 2314) used. 8. Identify the extent that rated power is affected by increasing inlet and exhaust losses. 9. Provide turbine-generator set package dimensions. If the unit is provided with standard shock/vibration mounting, provide dimensions of the unit with and without the standard mounting (if available). 10. Provide total estimated package weight (dry and wet) (identify major components included in package), and centers of gravity. Responses should indicate enough detail so that potential Navy interest can be assessed. Information should be e-mailed to Mr. Christopher Paulus at christopher.paulus@navy.mil or mailed to Naval Sea Systems Command, Attn: Mr. Christopher Paulus, PMS320, 1333 Isaac Hull Avenue SE, Washington Navy Yard, D.C. 20376 and labeled with the solicitation number. Responses are requested by 10:00 am (EST), on 31 August 2012. However, submissions will be accepted after this date, but feedback may not be as timely or contribute to NAVSEA ™s strategic planning. Responses are requested to be provided electronically and acceptable formats include Adobe PDF, Microsoft Word and Microsoft PowerPoint files. Questions can be submitted electronically to christopher.paulus@navy.mil and adam.goldberg@navy.mil. Information provided shall be treated as Business Sensitive and will not be shared outside of Government activities and agencies without the permission of the provider. This RFI in no way binds the Government to offer contracts to responding companies. The information provided will assist NAVSEA in developing and further defining future procurement and acquisition strategies. Defense and commercial contractors, including small businesses, veteran-owned businesses, service-disabled veteran-owned businesses, HUBZone small businesses, and woman-owned small businesses are encouraged to participate. This RFI is the initiation of market research under Part 10 of the Federal Acquisition Regulation (FAR), and is not a Request for Proposals (RFP). All information shall be provided free of charge to the Government. NAVSEA may request further information regarding the capabilities of respondents to meet the requirements and may request a presentation and/or a site visit as deemed necessary.
