8.8.2 Maneuvering at overload
The engine should only be operated at overload (110% of CMCR power) during sea trials and
when there is an authorized representative of the engine builder on board the ship. The limit for
operation of the engine at overload is a maximum of one hour each day (refer also to section
3.3 The relation between engine and propeller).
During operation at overload, you must carefully monitor the engine. If there are unusual
indications, you must decrease the load (power).
The load indication (fuel injection quantity) and the exhaust gas temperature upstream of the
turbocharger show the engine load.
The cooling water temperatures must stay in their usual ranges.
The maximum permitted position of the load indication (fuel injection quantity) is given in the
acceptance records. The adjustments are only permitted to show the CMCR power during sea
trials with an overspeed of 104% to 108% of CMCR power.
