Why do we have an Emergency Bilge Suction AND a Direct Bilge Suction?
​
Hello chiefs engineers of reddit. 4E on tankers btw, would sound like a stupid question but I'm asking it anyway
It seems redundant to me seeing how they seem to serve basically the same purpose, which is to pump out huge volumes of water in an engine room flooding, but the emergency bilge suction is slightly more elevated compared to the direct bilge suction. Plus the pumps driving these suctions are different as well. For what reason do we have these two distinct pumping arrangements together onboard?
