Hi Tore,
I have got another off-topic question. The schnorchel mast on KNM Kaura was elevated by means of hydraulic power taken from the installation for periscopes hoists. I wonder, if there was any emergency procedures, in case of damaging hydraulic installation (the periscopes could be raised and lowered by hand). When almost all systems were backed-up, it would be strange to be not able operate schorchel without hydraulic power. Maybe there was some kind of hand pump to build the pressure in installation?
