Norsok Standard Z-005-1997 2D-CAD drawing standard

The Norwegian Oil Industry Association (OLF) and Federation of Norwegian Manufacturing Industries (TBL). Rev. 1, October 1997. The primary purpose of the standard is to define a common format for drawing files in the handover phase between companies.
The entire lifetime of the drawing file has been taken into account; from the very beginning of a project to operation and maintenance phase. The standard is divided into a general part and specific annexes for the two most common 2D-CAD systems in the oil and gas industry.
