28 -- Fairbanks Morse Proto-type Engine Overhaul/Modification

This is a notice of intent that the United States Coast Guard, Maintenance and Logistics Command, Atlantic intends to solicit and negotiate with only one source under the authority of FAR 6.302 for a sole source contract with Fairbanks Morse Engine Division to Proto-Type Overhaul / Modify One (1) Fairbanks Morse 3800D8 1/8 Model 38D8 1/8 Diesel Engine. The U.S. Coast Guard issued a sources sought synopsis (Reference number-21058053FA920, Posted January 14, 2005, Response Date January 24, 2005), no responses were received. Interested persons may identify their interest and capability to respond to this requirement within 10 calendar days of this notice. The approximate issue date for the solicitation will be February 14, 2005. The prototype engine overhaul / modification will be to a single diesel engine on the USCGC KATMAI BAY, a 140 WTGB Icebreaking Tugboat located at Sault St. Marie, MI. Overhaul /Modification will be done at the vessel's homepier in Sault St. Marie, MI. Vessel's availability schedule is for twenty-five (25) calendar days starting April 25, 2004. The following services being requested to Overhaul and Modify the Fairbanks Morse Engine are: (1) Evaluate the existing diesel engine's salient features, to include the operating conditions, conditions of the existing machinery, review of the available service records of the engine, and the application of OEM and after-market components. (2) Install exchange or rebuilt fuel injection pumps to produce a change to the existing injection timing of the engine to achieve higher exhaust temps at lower engine loads. (3) Install an external motor-driven vacuum fan to ensure that the engine remains under proper vacuum irrespective of engine speed. (4) Install an air-operated, PLC controlled, temperature control valve in the engine's jacket water system. The valve will be configured to regulate jacket water temperature based on existing lube oil temperature. (5) Install a PLC control panel to control the above mentioned control valve as well as the existing air by-pass actuator for the installed blower. (6) Install a crankshaft air seal to reduce lost crankcase vacuum. (7) Calibrate the existing Lube Oil Sump bayonet gage to ensure it complies with engine OEM Service Bulletin, Volume - A, Issue 12, dated June 22, 1987. (8) Perform an inspection of the engine's existing vertical drive shaft assembly and provide a report on the condition of the components relative to the OEM tech manual. (9) Perform an inspection of the engine's existing roots blower and provide a report on the condition of the components relative to the EOM tech manual. The inspection shall include the conduct of an air test. (10) Perform an inspection of the engine's existing gear train at the free end of the engine and provide a report on the condition of the components relative to the OEM tech manual. This upgrade/overhaul is a prototype modification that will address documented concerns associated with light load operation, while maintaining optimum high icebreaking steady state and transient performance. The light load concerns include excessive oil injection into the exhaust manifolds and piping. Excessive exhaust oil injection also leads to the cutter's topside surfaces getting coated with a slippery film of oil. The oil injection is also an environmental concern, whether carried directly into the sea, or into the bilge. The second primary low load concern is high smoke opacity. The prototype installation goals are intended to demonstrate a Fairbanks Morse Engines proprietary modification approach that will successfully address the low load concerns, while maintaining optimum icebreaking steady state and transient load performance. The engine is a unique opposed piston design. One of the environmental concerns associated with the 140 WTGB MSA main engine design decision is whether a modified Fairbanks Morse 8-38D8-1/8 engine will have to meet Environmental Protection Agency Tier 2 exhaust emission requirements. The only known source to the Government for the services listed above is Fairbanks Morse Engine, Beloit, WI. There may be vendors that can repair and tune the FBM diesel, but as a result of these unique design characteristics, it is believed that only the OEM, Fairbanks Morse Engine Division, possesses the design criteria, historical expertise, and technical ability to develop a new load-carrying profile for this engine. The desired outcome of the engine modification should allow the vessel to operate safely and environmentally compliant at lower vessel speeds associated with new DHS Law Enforcement duties. All reference documents are available for viewing at 300 East Main Street, Suite 600, Norfolk, VA 23510-9102. There are no drawings applicable to this requirement.
