Completing the Battening Down quest in Arc Raiders took me longer than I expected. Usually I'm pretty good at sussing out locations, but one in particular, the leaking oil pipe you have to repair, is actually very hard to find. While you get directions pointing you towards the correct pipeline, no parts of it are visibly leaking, so it's hard to be sure until you find the spot.
You also have to photograph the seal wall and sample some seaweed, but those parts are much easier. All that said, here's how to complete Battening Down in the new Riven Tides update.
