Thanks for your input again all. I've established a model based on ISO 15550 (Internal combustion engines - Determination and method for the measurement of engine power) which should give somewhat of a correction based on the performance of the engine. Going to check this model with engine makers. O...

Will look into those vessels as well as the slip, see if I can get some theoretical and practical values and calculations on that.

Additional question to all; is there a way to calculate engine shaft power/torque without a meter on the shaft? By calculation on input/output temperatures or whatever?

Hi Big Pete, Thanks for the welcome and the thorough reply. Most of the information was roughly known, however I didn't know about the propeller calculations and the perforated pipe system plus bubbles in the water etc. Any more information on the system and it's calculations? Of course the engine d...

Hi all, I am a mechanical engineering student in Delft, the Netherlands and I'm conducting a research on ship performance in different ambient temperatures. So far I'm mainly focusing on finding reduction factors or formulas which can tell me how a engine performs in different climates. A ship (and ...
