Description

This is a correction to the notice posted Sept. 19, 2000. The discription in the previous notice is replaced with the following: NAVSEA -- Philadelphia is seeking expressions of interest, general information, and data from potential sources regarding diesel engine NOx and PM emissions reduction technologies. A Navy Pilot Diesel Engine Exhaust Emission Reduction Retrofit Program is being considered to evaluate selected technologies. Technologies successfully evaluated may then be selected by various Navy field activities for retrofit on their vessels. This information is being solicited in response to requests from shore facilities in Clean Air Act (federal) and/or California nonattainment areas, and to the EPA announcement in Mar 00 of its Voluntary Diesel Retrofit Program (patterned after the EPA's ongoing urban bus program). The EPA has set a goal of retrofitting 10,000 existing diesel engines over the next two years and is focusing on the urban areas with the most significant air pollution problems. The primary goal is to reduce NOx and PM emissions more rapidly than would otherwise be accomplished by relying solely on the introduction of new low-emission engines in the process of engine attrition. It is anticipated that the EPA will participate in the Navy pilot program. The Maritime Administration (MARAD) is also considering participation with a particular interest in the suitability of technology to commercial maritime applications. The Navy is targeting its pilot program at one or more urban areas where there is a significant Navy presence, a nonattainment classification is in effect, and a set of emissions caps is in place (e.g. San Diego, San Francisco, and Seattle). Navy field activities have been sought that would be willing to invest further in applying the pilot program NOx and PM reduction technology/ies to other diesel engines. This program will include both controlled lab testing (focus is on assessing performance via back-to-back mode tests) of several different technologies or combinations of technologies and a follow-on shipboard evaluation (focus is on assessing maintenance and durability during normal vessel operations). The program is directed toward dry exhaust (common method of cooling in marine installations with exhaust exit at the transom or hull side and an exhaust pipe riser to prevent seawater backwash) marine engine applications and, more specifically, the Navy's service craft and small boats. Detroit Diesel Corp. (DDC) 71 Series engines (~2,000 in high usage applications) are the prime candidates for emissions reduction. As the Navy's single largest group of older engines, this engine family makes an attractive sub-population for emissions control. The model under primary consideration for the pilot testing/installation is the DDC 12V-71N (naturally aspirated). The following two engine subsets -- distinguished according to type of fuel used -- will be considered for the pilot program: 1. Those engines that are installed in vessels that are dedicated to particular Navy ports/shore activities and fueled from the field activities' fuel farms -- these vessels will be fueled exclusively with JP-5 (fuel sulfur cap of 4,000 ppmw and average fuel sulfur content of 470 ppmw); and 2. Those engines that are installed in vessels that cannot be assured of a dependable JP-5 fuel source and therefore exclusive JP-5 fueling -- these vessels will continue to be fueled primarily with Navy Distillate (NATO F-76) fuel (sulfur cap of 10,000 ppmw and average fuel sulfur content of 5,400 ppmw). The specific distribution of fuel sulfur content for these two fuels are as follows: 1. F-76: 46% of fuel contains 0 -- 5,000 ppmw, 30% contains 5,000 -- 7,000 ppmw, and 24% contains 7,000 -- 10,000 ppmw; and 2. JP-5: 46% of fuel contains 0 -- 500 ppmw, 29% contains 500 -- 1,000 ppmw, and 25% contains 1,000 -- 1,500 ppmw. Post-turbine maximum exhaust temperatures for the dry exhaust engine (DDC 12V-71N) installations ranges from approximately 450 F at idle to 800 F at full load and the maximum specified exhaust back pressure ranges from 3.3 -- 5.5 in. Hg. Operating profiles differ significantly by application, however, examples of four profiles across the spectrum (in order of ascending load factor) of DDC 12V-71N installations are provided as follows: 1. Torpedo Recovery Boat (TRB): 20% operating time at 45% load, 10% at 5% load, 70% at idle; 2. Landing Craft, Mechanized (LCM) and Landing Craft, Utility (LCU): 70% operating time at 65% load, and 30% at idle; 3. Torpedo Retriever (TR): 10% operating time at 90% load, 50% at 80% load, 20% at 50% load, and 20% at idle; and 4. Barge Crane, Self-Propelled (YSD): 50% operating time at 100% load, 25% at 40% load, and 25% at idle. Engine model years being considered are primarily from the 1980s and factory emission rates (full load and rated speed) obtained from the OEM for these years for DDC 12V-71N engines are on the order of 9 -- 23 g/bhp-hr NOx , 6 -- 49 g/bhp-hr CO, 0.15 -- 0.55 g/bhp-hr HC, and 0.2 -- 1.6 g/bhp-hr PM. Although there have been no specific NOx and PM emissions reduction goals defined for this program, significant reductions of either or both constituents must be maintained for the duration of the life of these engines if the program is to be successfully promoted and funded. The Navy is seeking to identify promising technologies -- whether commercial off-the-shelf (COTS) or edge-of-the-shelf (EOTS) -- that would yield significant reduction of NOx and/or PM emissions with the aforementioned engines and under the aforementioned conditions. Those emissions control manufacturers possessing such technologies can inform the Navy by providing the following information for the DDC 12V-71N, other DDC 2-stroke engines, or any other diesel engine models used widely in the Navy (in that order of preference) no later than 4 October 2000 (indicate whether information is applicable to fueling with JP-5, F-76, or both; and whether information is applicable to dry exhaust, wet exhaust, or both): 1. Name and model of technology; 2. Units in the field and examples of maximum hours accumulated per unit; 3. Estimated cost ($) on a bhp-specific basis; 4. Estimated NOx and/or PM reduction (% based on resultant g/bhp-hr); 5. Estimated dimensions (in.), volume (in.3), and weight (lb.); 6. Materials list; 7. Application examples similar to that under consideration; 8. Operational limitations (fuel sulfur, regeneration minimum temperature, engine PM generation, etc.); 9. Applicable laboratory test data (performance, emissions, reliability, maintenance, and durability); 10. Applicable field test data (performance, emissions, reliability, maintenance, and durability); 11. Description of technology and operating principles (relevant SAE technical papers or other peer-reviewed published papers preferred); 12. Maintenance requirements; 13. Durability estimate; 14. Disposal/handling of hazardous material requirements; and 15. Further development required and time required to complete development. This is not a request for proposal and does not commit the Government to the award of a contract. Any comments provided may/may not be included in a formal solicitation. The Government will not pay for any information received in response to the RFI nor will the Government compensate any respondent for any costs incurred in developing the information provided to the Government.
