A -- TECHNOLOGIES, PROCEDURES, CONCEPTS, SYSTEMS, ALTERNATIVE MATERIALS, OR DEVICES TO REPLACE, MINIMIZE, OR PROCESS POLLUTANTS PRESENT IN WET EXHAUST FROM SMALL BOAT DIESEL INBOARD AND GASOLINE OUTBOARDS PROPULSIONS ENGINES SOL N00167-99-SS-0010 POC C. Joan Miles, (301) 227-1100, Catherine L. Rowe, (301) 227-1100 The Carderock Division, Naval Surface Warfare Center (CDNSWC) is seeking sources to provide technologies, procedures, concepts, systems, alternative materials, or devices to replace, minimize, or process pollutants present in wet exhaust from small boat inboard diesel and outboard gasoline propulsion engines. These small boats and craft may range in size from 12-192 feet. Outboard engines currently on small boats and craft may be as large as 225 horsepower (hp); most inboard engines range in size up to 500 hp, although some may be as large as 2250 hp. Small boat engine wet exhaust discharge is seawater that is mixed and discharged with small boat propulsion engine exhaust to cool the exhaust and quiet the engine. Constituents from the engine exhaust are transferred to the injected seawater and discharged overboard as wet exhaust. This discharge may include benzene, toluene, ethylbenzene, and naphthalene and total polycyclic aromatic hydrocarbons (PAHs). Potential offerors are requested to respond with technical documentation supporting the technology, concept, system, alternative material, or device. The proposed solution must demonstrate the ability to control, reduce, or eliminate some or all of the discharge constituents listed above. Additional information should include, but not be limited to, the following: process description, current commercial or military applications, specific applications in the marine environment (including customer references/ship class/name), processing rate capability, normal operative and maximum permissible pressures, physical size, total dry and wet weights, maintenance requirements, operational manning requirements, power consumption per hour of operation, utilities required, secondary wastestreams generated, and equipment performance and testing results. Technical, industry, or professional society certifications or endorsements should be provided if available. A summary of agents or contaminants which could potentially interfere with the operation and performance of the technology is also requested. In evaluating the submissions, DoD will consider the following criteria: (1) the nature of the discharge that the technology, concept, system or device is designed to process, (2) the effectiveness of the technology, concept, system or device at mitigating the environmental effects of that discharge, and (3) the technology, concept, system or device's cost, practicability and effect on operations or operational capability when installed and used on a vessel. This synopsis is for information purposes and to identify potential technologies and offerors. This sources sought announcement does not constitute an RFP and does not obligate the government in any way to purchase or test any of the potential solutions offered. Further, it does not commit the government to pay for any proposal costs in response to the sources sought announcement. Submit responses for this synopsis to Carderock Division, Naval Surface Warfare Center, Code 633, Attn: Sheila Riggs (Small Boat), 9500 MacArthurBoulevard, West Bethesda, Maryland 20817-5000. Responses to this sources sought announcement must be received requested within 45 days from the date of publication. For additional technical information on small boat engine wet exhaust, refer to the nature of discharge (NOD) report available at http://206.5.146.100/n45/doc/unds/Proprule/Rule_idx.html or http://www.boats.dt.navy.mil and go to "project gallery" to learn more about the Navy's small boats and craft.
