Inland oilrig and player deaths

So this is an issue I've encountered in the past with other maps and the water base plugin.
If a player builds too close to the oilrig it will consider the player to be on the monument.
And after X time it will "suicide" the player to control sleeper population.

All I can think is adding a nobuild sphere around it. As far as the actual required distance. I can't really say what that is.
I just know that players are able to build too close to the monument.
I just tried this myself to confirm it's still an issue and my sleeper was killed approximately 32 minutes after signing off.
