Just as a side note, Kilos can be very quiet when well run and maintained. And they can stay that way for days. But when they have to come up for air (to run the diesels and recharge batteries) they sound like "two skeletons f***ing in a trash can" as told me by several sonar techs.
It is only by the very narrowest of margins that I managed to avoid spraying my monitor with beer.
