Machinery Repairmen are skilled machine tool operators. They make replacement parts and repair or overhaul ship's engines and auxiliary systems. They also work on deck equipment including winches and hoists, condensers and heat exchange devices. MRs occasionally operate main propulsion and auxiliary machinery in addition to performing machine shop and repair duties.
What They Do
The duties performed by MRs include: repairing and operating auxiliary machinery; calculating time and material needed for machine shop work and the repairing of auxiliary machinery; drawing sketches and preparing specifications for replacement parts; working from sketches and specifications to produce replacement parts; operating machine shop equipment, such as lathes, drill presses, shapers, bench grinders, milling machines, boring mills, power hacksaws and computer numerically controlled machinery; working with precision measuring instruments such as micrometers, depth gauges, verniers, calipers, gauge blocks, protractors and dial indicators; engraving metal and other materials; performing electroplating and flame spraying operations.
People in the MR rating usually work indoors in a machine shop situation where many motor-powered machine tools are present. They work closely with others and are closely supervised.
