    • Pay attention to readings for deviation from normal, particular attention being made to exhaust gas temperatures, scavenge temperatures and pressures and turbo charger revs.
    • Adjustments should be made for sea water temperature, changes to keep pressures and temperatures.
    • Checks should be made on the pressure drops across fuel and lubricating oil filters to see that they are operating within the required limits.
    • Check all oil levels in auxiliary machinery, main engine sump levels, cylinder lubricators, turbochargers and governors.
    • Check around all bearings and crankcase doors using the palm of your hand to feel for any increase in temperature.
