New edition of NORSOK E-001 Electrical systems published
This NORSOK standard contains provisions for electrical installations at voltages up to and including 35 kV AC and 1 500 V DC to provide safety in the design of electrical systems, selection, and use of electrical equipment for generation, storage, distribution and utilization of electrical energy for all purposes in offshore units which are being used for the purpose of exploration or exploitation of petroleum resources. The new edition was publised by December 2016.
This NORSOK standard is based on equipment and practices, which are in current use, but it is not intended in any way to impede development of new or improved techniques.
This edition of E-001 gives requirements and recommendations in addition to the IEC 61892 series of standards.
This NORSOK standard is applicable for the voltages stated above, even if a different voltage limit may be given in some of the parts in the IEC 61892 series of standards. It is expected that the voltage levels in the IEC 61892 series of standards will be corrected as part of the maintenance cycle of this IEC standard.
The Excel files of the thirteen EDS can be downloaded from the NORSOK EG E-001 web page.
