Working with some data in the North Sea and basically I'm a bit fed up of working at a slant of 43.22 degrees. I was thinking it must be possible to define an orthogonal local coordinate system as a .prj file for my area. However I have no idea how to do this...
The desired centre of such a grid would be at 2°0'0"E 55°0'0"N and rotated by -43.22 or +46.78 so that the boxes in the image below go from rotated to orthogonal.
I managed to solve this myself by defining a .prj using a tutorial found at:

For anyone to check, I used the bottom left corner as my origin and set the rotation to -43.22/136.78 and ended up with:
PROJECTION["Local"], PARAMETER["False_Easting",0.0], PARAMETER["False_Northing",0.0], PARAMETER["Scale_Factor",1.0], PARAMETER["Azimuth",-43.22], PARAMETER["Longitude_Of_Center",1.42624], PARAMETER["Latitude_Of_Center",55.102476],UNIT["Meter",1.0]]
