Marine Log - March 2009 - (Page 26) ON THE COVER DROPPING IN TIER 2 COMPLIANT ENGINES M arine journalist Alan Haig-Brown was on hand at Intracoastal Iron Works in Bourg, La., when the shipyard was installing new Tier 2 compliant engines into an inland river pushboat. Haig-Brown took a series of photos of the installation process, including the one above and on this month’s cover. While Intracoastal Iron Works’ Joey Portier has performed countless engine installations, this one was a bit different. Last December, a client for one of Intracoastal Iron Works’ standard 72 ft x 30 ft pushboats specified the QSK38 for a boat under construction. While the Tier 2 compliant QSK38 engines share the same block dimensions as the mechanical KTA38 diesels, some of its accessories have increased the exterior dimensions and its overall weight. The increase in the dimensions of the new engines raised the bar for the installation, but Portier approached the job with his usual aplomb. Within three or four hours the engines had been lifted from the shipping skids and lowered through two decks to their engine beds in the new hull. To fit through the main deck they had to be tilted with the forward end down as Portier directed his crew to move the several chain-driven comealongs from position to position to manage the job with ease. 26 MARINE LOG MARCH 2009 www.marinelog.com http://www.abb.com http://www.abb.com http://www.marinelog.com
