I can not move the base.

You may be able to relocate - the jump will move you backwards a little but will not move you to the edge of the world.

Which world are you referring to?

Server Europe 6
Base coordinate
424: 276
I need to relocate the base to another location.
Is not repair possible?
I can not move to another place.

I'm just looking at some old map's here now, but from the coords it looks like you have a lot of Forgotten bases around you and not any free space to land on...
If you relocate to another sector the game will find you empty (free) spots in that area, but it will move you back if nothing is empty close enough to the center...

Go to the world map, press 'Relocate player' select sector and check the box, and agree to the warning...
