The stated heat d<strong>is</strong>sipation, capacities of gas and engine-driven pumps are given at 720 RPM. Heat d<strong>is</strong>sipation gas and pump capacities
at 750 RPM are 4% higher than stated. If L.T. cooling are sea water, the L.T. inlet <strong>is</strong> 32° C instead of 36°C.
Based on tropical conditions, except for exhaust flow and air consumption which are based on ISO conditions.
* Only valid for engines equipped with internal basic cooling water system nos. 1 and 2.
** Only valid for engines equipped with combined coolers, internal basic cooling water system no. 3.
*** To compensate for built on pumps, ambient condition, calorific value and adequate circulations flow. The ISO fuel oil consumption
<strong>is</strong> multiplied by 1.45.
