Installs below-deck auxiliaries, such as evaporators, stills, heaters, pumps, condensers, and boilers and connects them to steampipe systems. Tests and inspects installed machinery and equipment during dock and sea trials. May set up and operate such machine shop tools as lathe, boring mill, planer, shaper, slotter, and milling machine to fabricate replacement parts.
