From 16 to 20 September 2019, we carried out an audit of Gassco relating to electrical facilities and associated installations on the Draupner facilities.

Draupner S and Draupner E are located in block 16/11 in the North Sea and are an important hub for the gas pipeline network on the NCS.

Gassco is the operator of the facilities and employs Equinor ASA (Equinor) as a technical service provider (TSP).

Objective

The objective of the audit was to monitor how Gassco and its TSP comply with the technical, operational and organisational regulations for electrical facilities and associated installations. The objective was to monitor the company’s work on barrier elements relating to ignition source control, ventilation (HVAC), emergency power and emergency lighting.

The audit detected 12 non-conformities. These concerned:

  • The operator role and competence
  • Responsible person for the electrical facilities
  • Non-conformity handling
