The document describes sea water supply and return lines for a marine scrubber tower system. A DN300 main line supplies sea water to the scrubber tower and returns diluted water through the main engine casing from Deck 17 to Deck 5. Branch lines include a DN300 return, DN300 SMO 254 feed pipes, and modified general service cooling lines assist with water dilution from the scrubber tower.
