scope:

The purpose of this NORSOK standard is to outline the necessary data- and telecommunication services needed onboard a drilling unit in order to fulfil the operator's requirements for voice and data communication between the drilling unit and the operator's communication networks, regardless of distance to shore. It also forms the basis for achieving cost reduction by combining drilling contractor's and operator's needs for similar services.

This NORSOK standard does not address any aspects regarding the drilling unit's own operational needs or any requirement with which the drilling unit shall comply in order to meet mandatory requirements. The complementary onshore facilities are not dealt with in this NORSOK standard.
