Supply to the Government two (2) U.S. EPA Tier 3/IMO certified diesel generators producing 250 eKW / 480 volt 3 phase / 60 Hz generator sets per the below specifications. Description of Current Generator Arrangement: Two diesel generators are the prime electrical power source for the quarter’s barge Taggatz. The generators work as a standalone electrical power system. There is paralleling capabilities between the port & starboard generators so there is a closed transition when switching from either the port or starboard generator sets. There are no load sharing capabilities with this setup. The current generators have an electrical over mechanical governor setup. The diesel engine speed and voltage is adjustable from an external location on the main switchboard. The generators have indoor sound attenuation enclosures. The rough dimensions of each generator enclosure are: length 136” – Width 55” – Height 58”. The quarter’s barge is 160’ x 40’ in dimensions and houses approximately 60 crewmembers. The Taggatz has a full galley and mess for preparing and serving the crewmembers meals. The Taggatz currently has two M?6140 Northern Lights generator sets. Each has a rating of 330 kilowatts, producing 480 volt / 60 Hz / 3 phase power to the main switchboard. The rated speed for the generators is 1,800 RPMs. The current generators are oversized for the electrical load on the Taggatz, therefore this requirement is for smaller units. The Taggatz has an external hull mounted Fernstrum Keel cooler for each generator engine with a model number of DD16147W?ZE1S2 to provide the cooling for the generators. The cooling mechanism is a closed loop system. The discharge engine coolant passes through the Fernstrum keel cooler and the outside river water cools the coolant as it returns to the diesel generator. The coolers are sized with zero knot water flow over the coolers at a maximum river water temperature of 90 degrees. New Diesel Generator Specifications: The following paragraph outlines the featured design and capacity provisions for the replacement marine diesel generators. The supplied diesel generators shall be U.S. EPA Tier 3/IMO certified diesel generators producing 250 eKW / 480 volt 3 phase / 60 Hz electrical power to the main switchboard. The generators design shall be a permanent magnet excitation type (PMG). It shall have an installed digital voltage regulator. The digital voltage regulator at a minimum shall have the capability for voltage, droop, gain and stability. The generator shall incorporate marine class H insulation with a class F temperature rise. The generator shall be of a single bearing design. The generator shall have anti?condensation space heaters installed in the generators. The diesel engine shall be electrically governed. The fuel system shall be a high pressure common rail, direct injection system. (HPCR) The generator diesel engine shall incorporate an electronic control module (ECM) to control the response of the engine to the demand of the electrical load. The engine shall be programmable for a low idle condition, for warming the engine before placing online. The electronic system shall display diagnostic and fault codes, to include an emergency shutdown devise. The engine, at a minimum, shall have shutdowns for low oil pressure, high jacket water temperature and overspeed. The engine shall incorporate an engine coolant block heater. The exhaust manifold and turbocharger shall be water?cooled. The generator mounting shall be configured as a soft engine and generator mountings to reduce vibration. The generator diesel engine water pump shall be capable of circulating coolant through the current keel cooler setup. It shall have a duplex engine oil filtration system. The fuel system shall have duplex filtration systems on the primary and secondary fuel systems. The generators shall have remote voltage and engine speed capabilities. The engine at rated speed shall not exceed 1800 RPMs. The max combined heat rejection to coolant from the jacket water & aftercooler circuit shall not exceed 17,500 BTU/per minute. The generator setup shall be furnished with a sound attenuation enclosures. If this is not a factory option, an aftermarket enclosure will be acceptable, provided the aftermarket enclosure will fit the generator set being provided. The level of sound output shall be between 70 to 89 d(B)A. The sound attenuation enclosure will not require a muffler as the quarter’s barge Taggatz have them already installed. Miscellaneous: Contractor shall provide shop drawings and equipment brochures for the generator, as part of the quote, for Government Approval, to ensure the proposed product meets the Government’s requirements and dimensions. In advance of the generators the manufacture and/or distributor, shall provide detailed mounting blueprints/schematic drawings. Any distributor or manufacture preparing a proposal for submission requiring a preliminary inspection of the current set?up, shall do so at their own expense. Generator package shall include two (2) diesel generators as specified above. Two (2) operator manuals, two(2) parts manuals and two (2) service manuals shall be included with the generators. Freight (FOB Destination) to the address listed below shall be included in the quoted cost. The U.S. Army Corps of Engineers will provide the manpower resources and equipment to position the generators, connect any electrical lines, exhaust piping, fuel connections and modify the mountings for installation.
