Harrington Metal Furnishes Specially Modified Nozzles For 'City of Pittsburgh'

Harrington Metal Fabricating and Machining Co., Inc., Fennville, Mich., recently delivered two specially modified 103.4-inch nozzles with stainless steel interior skins to Ashland Oil, Inc. for refurbishing the 3,200-hp City of Pittsburgh, which recently underwent extensive stern rebuilding and replacement.

Marion Clendenin, Ashland maintenance supervisor, said replacement of the vessel's original Kort nozzles was a key item in the rebuilding project. The vessel's original Type 19 nozzles were replaced with Type 37 nozzles that were specially modified to increase water flow to the boat's propellers when backing.

The new nozzles were fabricated with stainless steel interiors flared both fore and aft from a single sheet of steel in a proprietary process developed by Harrington specifically for nozzles, according to Larry Monique, Harrington plant manager. Precise fits were obtained with the aid of the firm's computer-driven 60-foot gas/plasma cutting tables.

Harrington had fabricated two similar nozzles for the rebuilding of the Pittsburgh's sister vessel, City of Louisville, the previous year. The rebuilt vessel's improved performance prompted Ashland to proceed with plans for the City of Pittsburgh. Both vessels were built in the early '60s by Dravo Corporation.

Established in 1942, Harrington is a leading manufacturer of nozzles and custom fabrications for the maritime industries and offers complete design, engineering, machining, fabricating, blasting and painting facilities.
