- Synopsis: The Naval Sea System Command (NAVSEA) is hereby issuing a Request for Information (RFI) on behalf of PMS 320 (Electric Ships Office (ESO)), seeking information from all potential sources who may be interested in the development and manufacture of gas turbine-generator sets with an output rating of between 20 to 30 Megawatts electrical (MWe) (nominally about 25 MWe), for use on Naval vessels. The Navy is seeking information on potential gas turbine generator sets; the generator's electrical interface requirements; the impacts of those requirements on turbine-generator set performance and size; the availability of a marinized and militarized turbine-generator sets; and the estimated costs for any development steps needed to bring the turbine-generator set to an advanced/engineering development model state of maturity (e.g. Technology Readiness Level (TRL) of 6 or higher and the gas turbine is fully ready for qualification/performance testing). A long-term goal for this effort is to maximize military effectiveness through design choice and configuration option flexibility in developing next-generation distribution plants. This turbine-generator set would align with the needs identified in the Navy's 2015 Naval Power and Energy Systems (NPES) Technology Development Roadmap (TDR). The NPES TDR notes in the Mid-term Product Area Metrics section that there is interest with a stack-up length of less than 39 feet. The NPES TDR also references a need for prime movers with efficiency improvements of 5 to 20 percent over existing fielded systems. The Distribution Statement D version (Distribution authorized to Department of Defense (DoD) and DoD contractors only) of the NPES TDR can be provided upon request via email to joseph.tannenbaum@navy.mil and upon verification that the requestor is a bona fide U.S. Department of Defense (DoD) contractor familiar with the procedures to handle technical data packages that may include limited distribution information. Evidence in the form of an executed DD Form 2345 (MILITARILY CRITICAL TECHNICAL DATA AGREEMENT) will be required prior to transmittal. The following is a notional set of performance characteristics that meet the needs of a potential demonstration system, although consideration will be given to deviations from these parameters: A turbine-generator set package length requirement target of less than or equal to 39 feet. Generators with higher operating speeds (above 3600 rpm) would provide potential to reduce the overall stackup length of the turbine-generator set. The Navy is interested in future shipboard electrical architectures that may feature Direct Current (DC), 60 Hz. Alternating Current (AC), or a higher frequency AC output from the turbine-generator set package at the interface to the power system. The turbine-generator set package shall include any necessary equipment to convert the power produced by the generator to the power required at the interface. MIL-STD-1399 section 680 applies to 60 Hz AC interfaces. DC interfaces may have a nominal voltage of 6 kV, 12 kV or 18 kV. The Navy is interested in DC turbine-generator sets with two independent power interfaces, each capable of half the power rating of the turbine-generator set package. Operate on all of the following fuels: Military Specification, MIL-F-16884 fuel, Naval Distillate (NATO F-76) and Military Specification, MIL-T-5624 fuel, Aviation Turbine Fuel, Grade JP-5 (NATO F-44). The turbine shall also be capable of operating on Marine Gas Oil, when F-76 and F-44 are not available. Performance based on Fuel lower heating value of 42,798 kJ/kg (18,400 Btu/lb.) Meet the following standard operating conditions for Naval gas turbine engines (rated power within the envelope based on standard Navy first article test rating conditions): Inlet air temperature: -40 to 52 degrees C (38 degrees C at rated power, ISO standard 2314 measurement locations). Seawater cooling inlet temperature, -2.2 to 35 degrees C (35 degrees C at rated power) Relative Humidity: 0 to 100% (40% at rated power). Engine room temperature: -6.7 to 52 degrees C. Grade A shock rating per MIL-S-901D is anticipated. Ensure proper operation (ability to perform all normal operations at maximum continuous performance ratings and overload conditions 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 of plus/minus 15 degrees (static condition); Roll of plus/minus 45 degrees and plus/minus 30 degrees (dynamic condition); Trim (Normal) of plus/minus 5 degrees (static condition); and Pitch of plus/minus 10 degrees (dynamic condition). Trade space may include changes to intakes and uptakes and any adjustments to the exhaust system to remove restrictions inside the enclosure. In addition to turbine generator sets in the 20 to 30 MWe range, the Navy continues to also be interested in electrical power generation in the 9 to 15 MWe power range. On November 29, 2007, the Navy released a Request for Information for an Engine Market Questionnaire to assess the market and potential for development of 9 to 15 MW turbines that could be mated with a high speed generator (N0002408R4206). Any updates to information provided under that RFI would be beneficial. RESPONSES: Responses to this RFI should include supporting materials that allow an effective evaluation of your company's competence, experience, and overall understanding of the notional requirements that NAVSEA has identified. No page limitation is imposed on the responses. The following information is requested (please indicate if the information is an estimate or based on actual performance data) for existing or planned products that support the parameters listed above: 1. TURBINE MARKET: What are the turbines, and turbine-generator set packages, that you predict to be available in the next 2 to 15 year timeframe that can be "marinized" and "militarized" for use in Naval shipboard generator sets in the range of 20 MW or higher? In terms of turbine development market trends, where do you see your customers' future demand heading (e.g. airline industry and any customers of your commercial turbines)? What other industry applications are forecast for these new turbines (e.g. land-based power, off-shore power, military aircraft, merchant/cruise ships, etc.)? 2. TURBINE DEVELOPMENT STATUS: What is the development status of the turbine (e.g. is it an existing aero turbine core) and what are the steps necessary to bring it to a fully marinized and militarized standard, including shock and vibration qualification? Include a description of the turbine or core and its population base and applications. What would be beneficial is a risk assessment (likelihood and consequence score for each development step with corresponding risk waterfall). Are there any advanced technologies employed or planned that would reduce airflow requirements; increase power density; employ variable area turbine nozzle and variable free power turbine; implementation of any energy recovery and recuperation; or employ high temperature working fluid? What enhancements are recommended to meet the 5 to 20% fuel burn reduction? 3. SCHEDULE: What is the development timeline required from contract award to delivery of two complete turbine-generator sets to a Navy land based test site, including any estimated time to modify or develop the gas-turbine and complete factory performance testing, assuming an immediate start? As a guide, the Navy is interested in a schedule with fidelity sufficient to see approximately 10 to 20 steps articulated in a time-phased plan with milestones for key reviews/development gates and an indication of any significant long lead items. Steps shall include an assessment of modifications to existing gas turbine, air handling, and other systems. Engineering analyses required to develop confidence in the identified design modifications should be identified in the plan, as well as generator development effort and associated technical risks (with associated likelihood, consequence, and waterfall). Are there any alternative recommendations regarding endurance testing? 4. COST: What are the non-recurring engineering costs and unit production cost estimates, identified individually for the gas turbine, the generator, and the balance of the associated package? Please identify the sensitivity of production cost to volume of sales (quantity discounts). Also please indicate what order quantity would offset the need for Navy funding of the non-recurring engineering costs. Non-recurring engineering may take the form of a new power turbine design or the inclusion of a speed reducing gear between the gas turbine and the generator, although the preference would be for leveraging existing power turbine designs. Are there any minimum annual buys needed to sustain production? 5. TURBINE PERFORMANCE: To the degree such information is available for the baseline turbines from which the development is commercially or militarily derived, please provide turbine performance characteristics. This may include estimated specific fuel consumption (g/kW-hour) throughout the power range (at the 25%, 50%, 75%, and 100% load ratings). Gas turbine rated power level and output speed at standard Navy rating conditions (reference ABS-NVR Appendix 2 Table 2) (including a power versus RPM versus SFC map, if available). Rated power stated in terms of both a flat rating and a tent rating curve. Flat rating shall correspond to a 2,000 hour hot section rework interval at an ambient temperature of 38 degrees C. Tent curve rating shall be stated at the ISO 2314 rating conditions, shall correspond to a 12,000 hour hot section rework interval and shall be stated, at a minimum, at 38 degrees C and at the ambient temperature associated with the maximum output power. Additional parameters of interest include: Estimated turbine inlet plenum dimensions; Estimated gas turbine-generator package and turbine only envelope dimensions and any known maintenance envelopes; Total estimated package weight (dry and wet) (identify major components included in package); Gas turbine intake air flow requirements; Gas turbine enclosure cooling air flow requirements; Gas turbine estimated exhaust mass flow rate; Gas turbine estimated maximum exhaust temperature and Turbine Inlet Temperature at rated power; Discussion of the potential to derive torque from both ends of the turbine module; and Exhaust emission at rated condition (NOx, SOx, THC, CO2, O2 and H2O). Define the power and life impact of exhaust loss increases from 10 inches of water (rating condition) to installation losses of up to 20 inches of water and inlet loss increases from of 4 inches of water (rating condition) to installation losses of up to 20 inches of water (including filter), and for exhaust loss for rating of 6 inches of water with installation losses up to 20 inches of water. Provide an engine configuration description (for example, how many spools are in the turbine?) Assuming no constraints on generator set frequency response, what are the general load application and removal characteristics and what is the practical limit on the rate, and frequency, of load application and removal (in terms of MW per second) with and without impacting performance and turbine life? What is the impact of implementing a customer bleed air requirement on size and performance? 6. GENERATOR AND PACKAGE PERFORMANCE AND INTEGRATION: How does additional conversion hardware that may be required of a high frequency AC or DC output turbine-generator set impact the size, weight and power-ratio that are gained by the higher speed generator? What are the expected frequency and voltage responses to step load increases from no load to 50% of rated load, 50 to 100%, and 0 to 100% load and step unload from 100% to no load, 100% to 50% load, and 50% load to no load? What is the maximum ramp increase and decrease in load (MW/sec) that will remain within voltage and frequency tolerances? What is the pulsed load capability of the turbine-generator set? What physical testing and/or modeling and simulation has been performed to date to validate these capabilities? What impact does the use of direct water-cooled stator cores or stator windings, high speed generator sets, cryogenically cooled or combinations thereof have on size, weight, reliability, maintainability, initial cost and operational cost? What is the feasibility of installing a shipboard turbine-generator set athwart-ship and are there any related performance limitations (noting differences in pitch and roll)? What would be the needed design changes to allow for athwart-ship mounting? Any necessary power electronic conversion equipment to convert the high frequency AC or DC generator outputs to 60 Hz power is requested to be characterized (which should include power quality capabilities and limitations at the generator winding terminals ). For a notional medium voltage AC distribution system interface (may not apply to DC), power factors (e.g., 0.8 - 1 leading and lagging) as well as harmonic withstand capability (e.g., 15 percent maximum total harmonic distortion current) are requested to be characterized. What range of subtransient reactance/impedance is practical? What is the impact of increasing or decreasing subtransient reactance on size, weight, cost, and transient performance? What are the size, weight, and cost impacts of splitting the output windings of the generator, is there a delta to the impact of ratios other than 50-50, and is there an impact or practical limit of splitting the windings in more than two segments? What are the impacts to generator and turbine controls from splitting into segments? Are there examples that have been constructed in these configurations? What are the impacts to the turbine and the generator of variable speed operation in providing DC power? What is the concept used to control the generator set speed and voltage? For a DC generator, is the regulation of engine speed and voltage designed to optimize generator set efficiency? Does increased power density impact turbine life or reliability and in what way? What are the details of the turbine-generator set starting system? What are the details of the Engine Health Monitoring (EHM)? What are the details of approach to ensure stability? What are the details of the ability to parallel and load share between generators? The questions above are intended to provide the framework for industry feedback. While conforming to the listed questions is encouraged, feedback and responses will be accepted in all forms. Responses should provide enough detail so that potential Navy interest can be assessed.
