The whole thing is pretty shady.. I don't really get the points/renown thing.
BUT I can answer this, if you return to port, and end your current patrol everything counts. When you start your new patrol, you'll be sent out to a new area, within the area of the 100,000 ton area, 'big red circle on map'.
You'll have all the tonnage you already sank and the bar will be in the same place, basically you just have to head back out and sink more until the bar is full and the mission area is complete.
