Below Anonymous has constructed a hypothetical Table and Figure for situations involving lead-acid batteries (LABs).
Later this week (probably on April 5 and 7) Pete will publish Tables and Figures involving AIP and LIBs which Anonymous constructed.
By Friday this will amount to three articles which I will run together. This is noting that the blog publishing capacity does not appear technically able to publish 4 or 5 high capacity tables/figures in a stable way.
Table 1 (below) - Routines over 24 hours for a LAB-submarine:
- "Time/Snorting" The four coloured rows represent: 2 hours (in green) to snort at night -
when it is a dark night. Then 1 hour of snorting (in green) when it is still a dark night.
Purple represents fully submerged operation on LABs.
- The row "Shift" represents a three shift work system
In this system, each shift of submariners works for 6 hours then rests for 12 hours.
(red = shift A, yellow = shift B and blue = shift C)

TheGreen Snorting timesin Table 1 (above) coincide pictorally (as closely as I can get them!) with the times in Figure 1 below).

Figure 1 (above) represents a LAB capacity of 10MW.
- For a LAB an average discharge depth might be down 35%. [Discharge depth means
ratio of discharged capacity to capacity of batteries. A discharge depth of 35% means that
35% of energy of battery is released. In LABs, a deep discharge depth such as 70% would
cause irreversible damage to the batteries. For LIBs a deep discharge depth may be as
far down as 90%]
- Just before the first recharge, high speed performance is limited by the shortage of
capacity of the LABs. Timing of snorting will be affected by large waves or storms
[Pete Comment - The need for greater flexibility in snorting times is a major reason why
or more severe storms. Such a new snorkel may be included in 29SS, the first submarine of
a new class after the Soryu].
