19 -- UPGRADE PROPULSION SYSTEM SOL JD-00-0003 POC Joseph D'Felio (816) 426-7267, Ext. 225 E-MAIL: Click here to contact the contracting officer, Joseph.D.Dfelio@noaa.gov. Furnish all labor, material, engineering, equipment and each and every item of expense for the upgrade of the propulsion system of the NOAA research ship Shenehon. The ship is a 65 foot, 90 ton displacement steel hull vessel originally built in 1953 to U.S. Army T-boat design. The mechanicals and propulsion system are largely unaltered. The vessel is berthed in Muskegon, Michigan and will be available to the contractor on or about November 30, 2000 with work to be completed no later than April 30, 2001. The ship is to be covered by Shipyard Liability insurance while in the shipyard. The contractor shall conduct performance sea trials with the equipment manufacturer's representative and the NOAA crew prior to final acceptance. Work includes but is not limited to: (1) haul the ship out in dry dock or with a travel lift (hauling, dry dock, lay day and electrical services shall be quoted as separate items). (2) Replace the original diesel engine, a Caterpillar D375, with a new commercial diesel engine rated continuous medium duty' of at least 400 BHP with keel cooling. Installation will include any required modifications to the engine bed and new resilient mounts. Exhaust piping will be connected to existing dry stack mufflers. The engine mounted panel and the pilot house panel, as a minimum, will have a tachometer, water temperature gauge, gear pressure gauge and hour meter. Pilot house controls are to be electric and in accordance with the engine manufacturers specification. Emergency stop buttons are to be located in both the engine room and pilot house. A forward end PTO unit for a fire pump or hydraulic pump shall be quoted as a separate item. (3) Replacement of the original 2:1 reduction gear with a new gear box selected to provide optimum propeller speed for this type of vessel, provisionally 2:1. This reduction gear box is to be fitted with a clutch, thrust bearing and oil cooler. A trolling valve is to be quoted as a separate item. Pending inspection by the contractor and the Marine Superintendent, the existing shaft will be machined if necessary and mated to the gear box. (4) Installation of grid type keel coolers will replace the existing fresh water cooling. The quote should include separate costs for main engine keel coolers and grid coolers for the existing 20 & 30 kw ship service generators. (5) removal of the existing 150 gallon fuel oil day tank and transfer pump. The new main engine shall be plumbed to draw from the existing filters which will be supplied from either port or starboard saddle tanks. A cross over line currently exists. (6) The contractor shall quote a new propeller based upon the proposed main engine rated horsepower and RPM if the existing propeller will not fully utilize the available power. The design is to be for optimum speed and not bollard pull. The propeller diameter and pitch are to be selected to absorb the normal power output efficiently at both sprint and cruising speed. The existing original propeller is a 46 inch 3 blade. (7) The contractor shall quote removal of a non-water tight bulkhead at midship which currently separates the laboratory space and the fidely as a separate item. (8) Both port and starboard fuel tanks are to be inspected and cleaned. (9) All new or repair work shall be primed and repainted with marine grade paint to match existing colors. This is a total small business set-aside. SIC code 3731 applies. Drawings and specifications will be available on or about August 31,2000. A pre-bid conference is tentatively scheduled for the week of September 3, 2000. All responsible sources may submit a bid which shall be considered by the agency. All requests for bid documents must be in writing. Requests may be faxed to (816) 426-7530. Posted 08/17/00 (W-SN487069). (0230)
