Sulphur handle setup and regulation sheet 6 - OOCL Long Beac

Calculation of values for Sulphur dependent regulation mode.

Insert the following values:

name of vessel CV OOCL Long Beach

? lubricator piston [mm]7Lubricator plunger diameter

number of lubricator pistons per cylinder10Number of lubricator plungers per cylinder

lubricator stroke [mm]13.75Length of stroke limiter shim. - decrece shims length if rE.inj (calculated on sheet 'output values') exceeds 5

oil temperature (norm. 45) [C]45Oil temperature used to calculate the density

number of cylinders12Cylinders for the engine

min. feed rate setting [g/bhph]0.5Minimum allowed g/bhph (0.5 for K, L and S -engines)

load point for change to rpm proportional25%Normal is 25 % load

min. rev/inj15Normal is 15

rpm mcr (100% rpm)104RPM at max continues rating with reference to the original layout and test bed results.

mcr power [bhp]93120MCR power with ref to the original layout and test bed results.

power at 100 % rpm [bhp]83808Actual power at RPM MCR in the ship depending of the propeller (typical 10 % lower than MCR power for a large container ship) sulphur factor0.25g/bhph = sulphur factor times the sulphur percentage - Normal value is 0.25

nor.hi [%]150%The LCD can only raise the feed rate until nor.hi [%]. Normal is 150

Values normally not to be changed

100 % feed rate set.[g/bhph]0.8Specific consumption at 100 % feed rate setting. Normal is 0.8 g/bhph

PLEASE NOTE IF SHIMS ARE TO BE REDUCED DUE TO rE.inj > 5 REV/INJ - PLS. USE 11.25 SHIMS TO KEEP NUMBER OF VARIANTS DOWN.
