Finding the right place to survive.
Majority of people at the time of zombie apocalypse would stay near the main city or forest.
These are one of the worst places to be at the time of a zombie apocalypse because you never know when you will encounter one lurking around you.
Best place are water cuz these suckers don't know how to swim, which is where Oil platform comes in. (Even if they know how to swim, oil platform are far away from the shore and no zombie can make it that far)
Those things are massive floating cities where 2000 people can live for more than a year.
Literally cut off from human civilization and the only way to access it is through boats or ships and it can last upto 50 years.
You have everything you need to survive a zombie apocalypse. You get safety from being far away from human civilization, get food from fishing, get fresh water from desalination of seawater or you can stockpile from the mainland once a month.
