HAPPY NEW YEAR ALL INTERESTED IN THE TECHNICAL AND POLITICAL ASPECTS OF SUBMARINES :)
It is interesting to calculate the Australian Future Submarine's (was called Shortfin's) diesel generator requirements based on the Collin's displacements, speeds, diesel and generator outputs.

It is interesting to calculate the Australian Future Submarine's (was called Shortfin's) diesel generator requirements based on the Collin's displacements, speeds, diesel and generator outputs.
COLLINS COMMENT-DETAILS
Looking at Collins-wiki right-sidebar) the Collins is: 3,100 tonnes (surfaced), 3,407 tonnes (submerged including at snort depth), 10 knots (surfaced and snort depth (limited by water resistance against snorkel) and 20+ knots fully submerged
"3 x Jeumont-Schneider generators" (1.4MW, 440-volt DC) right-sidebar = total electrical generation is 4.2MWe
If power figures for the Collin's "3 x Garden Island-Hedemora HV V18b/15Ub (VB210) 18-cylinder diesels" right-sidebar are unavailable then inverting the standard 0.8 power factor gives 1.25.
So 4.2 x 1.25 gives Total output of 5.25MW for the Collin's 3 diesels = 1.75MW output per diesel.
Note that notorious unreliability and associated lower "not exceed" performance limitations apply to the power output of these Collins diesels.

PART TWO TOMORROW WILL BE EXTRAPOLATING DIESEL-GENERATOR REQUIREMENTS FOR AUSTRALIA'S FUTURE SUBMARINES
This is noting figures for Australian Future Submarines have been reconfirmed as 97m in length, 8.8m in diameter announced by Defence Industry Minister Pyne (November 14, 2017) and
4,500 tonnes (surfaced) using actually unchanged length - diameter figures already published at Australian Navy News way back on May 5, 2016.
