A -- SOURCE SOUGHT TO PROVIDE TECHNOLOGIES, PROCEDURES, CONCEPTS, SYSTEMS, ALTERNATIVE MATERIALS, OR DEVICES TO REPLACE, MINIMIZE, PROCESS, OR OTHERWISE CONTROL POLLUTANTS PRESENT IN SEAWATER PIPING BIOFOULING PREVENTION DISCHARGE GENERATED BY ARMED FORCES VESSELS SOL N00167-99-SS-0031 POC C. Joan Miles (301) 227-1159 Lynn Rowe (301) 227-1100 The Carderock Division, Naval Surface Warfare Center (CDNSWC) seeks sources to provide technologies, procedures, concepts, systems, alternative materials, or devices to replace, minimize, process, or otherwise control pollutants present in seawater piping biofouling prevention discharge generated by Armed Forces vessels. This discharge consists of the additives used to prevent the growth and attachment of biofouling organisms to the interior piping and components of seawater cooling systems on selected vessels, as well as the reaction byproducts resulting from the use of these additives. The most common seawater piping biofouling prevention systems are anodic biofouling control systems and chlorination biofouling control systems. Seawater discharged from these systems may contain residuals from the fouling control agent, namely copper or chlorine-produced oxidants. This discharge may also contain constituents normally found in cooling water including copper, nickel, silver, and various forms of nitrogen. Potential offerors are requested to respond with technical documentation supporting the technology, procedure, concept, system, alternative material, or device. The proposed solution must demonstrate the ability to control, reduce, or eliminate the discharge and some or all of its 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, procedure, concept, system, alternative material, or device is designed to process, (2) the effectiveness of the technology, procedure, concept, system, alternative material, or device at mitigating the environmental effects of that discharge, and (3) the technology, procedure, concept, system, alternative material, 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 only 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 Naval Surface Warfare Center, Attn: Sheila Riggs (Seawater Piping), Code 633, 9500 MacArthur Boulevard, West Bethesda, Maryland 20817. Responses to this sources sought announcement are due within 45 calendar days of the date of publication. For additional technical information on seawater piping biofouling prevention, refer to the nature of discharge (NOD) report available at http://206.5.146.100/n45/doc/unds/Proprule/Rule_idx.html.
