The objective of the audit was to verify that Statoil's management and follow-up of barriers complied with the company's and the authorities' requirements.

The audit also monitored that the implementation of the design and installation documentation for Johan Sverdrup complied with the preconditions in the plan for development and operation (PDO), with the regulations, and with recommended standards. This entails Statoil ensuring that the contractor, Samsung, is familiar with the design assumptions.

Result

The audit detected one non-conformity in the following area:

  • Measures for protecting rooms and equipment from fire

We found six improvement points in the following areas:

  • Firewater system
  • Possible weakening of fire walls
  • Preservation of electrical facilities and equipment
  • Short-circuit protection
  • System for mechanical completion and testing
  • Planning of training and practice in use of simulation tools

Johan Sverdrup

Johan Sverdrup is a field on the Utsira High in the central part of the North Sea, 65 kilometres northeast of the Sleipner fields. The water depth in the area is 110-120 metres. Johan Sverdrup was discovered in 2010 and the plan for development and operation (PDO) for Phase I was approved in 2015. The development solution for the first development phase is a field centre with four specialised platforms: living quarters, process, drilling and riser facilities. Production started in 2019.

The PDO for Phase II was approved in 2019. The development solution comprises a process platform and five subsea templates. Production from phase II started in 2022.
