Standardization – a hot commissioned by Norway’s oil and gas topic at UTC 2013 minister at the time. KonKraft’s report had aimed to ? nd measures to increase recovery from Norwegian oil and gas ? elds. It proposed six initiatives, one of which was greater standardization, to reduce costs in equipment, project pro- cesses, and documentation.

Since 2003, subsea standards in

Norway have been facilitated and driven by Standards Norge (Norway).

Standards Norway is the national mem- ber of the International Organization for

Standardization (ISO) and the European

Committee for Standardization (CEN).
