Vessel engine inspectors inspect ship and boat engines such as electric motors, nuclear reactors, gas turbine engines, outboard motors, two-stroke or four-stroke diesel engines, LNG, fuel dual engines and, in some cases, marine steam engines in assembly facilities to ensure compliance with safety standards and regulations. They conduct routine, post-overhaul, pre-availability and post-casualty inspections. They provide documentation for repair activities and technical support to maintenance and repair centres. They review administrative records, analyse the operating performance of engines and report their findings.
