Notification of order for Statoil – collection of environmental data from the Aasta Hansteen field

Statoil has been issued with a notification of order concerning the collection of environmental data from the Aasta Hansteen Field.

The Aasta Hansteen field is in the Norwegian Sea, approx. 120 km north-north-west of Norne and approx. 320 km west of Bodø.

The field is in its own meteorological zone which is not covered by other facilities. The facility is anchored in approx. 1300 metres of water and is accordingly affected by the Atlantic Current, whereas other facilities are mainly affected by the coastal current.

The Aasta Hansteen field's position is interesting in terms of weather forecasting and climate monitoring, and data from here will be included in sea area forecasts. The position also provides an opportunity for verifying model data. The Institute of Marine Research operates a buoy at 66o N and 2o E. The Aasta Hansteen facility lies at approx. 67o N and 7o E, and will be the only permanent facility in the Atlantic Current so far north in the Norwegian Sea. Observations from here may be important for the forecasts for the Continental Shelf closer to the coast and for the stretch from Bodø to Stad.

On this basis, the PSA has now issued Statoil with the following notification of order:
Pursuant to the Framework Regulations, section 69 concerning administrative decisions, with reference to section 46 of the Framework Regulations concerning oceanography, meteorology and earthquake data, Statoil is ordered:


  1. To have a visual service onboard Aasta Hansteen in addition to the instrumentation which generates automatically measured meteorological parameters and AutoMETAR.
  2. To supply METAR/AutoMETAR in accordance with NORSOK-N-002 (2010) Collection of metocean data, chapter 5.2. Statoil shall also supply meteorological measurements for forecasting purposes in accordance with NORSOK N-002 (2010) chapters 5.3 and 5.4. The instrumentation shall be in compliance with NORSOK N-002, appendix A. The siting of instruments shall be done so that sources of error are reduced to the greatest possible extent or eliminated. Wind shall be measured in m/s and cloud altitude in m, contrary to METAR where knots and feet are specified. Wind direction shall be measured relative to true north and not magnetic north as specified in METAR. Statoil shall adhere to NORSOK N-002 (2010) chapter 5.3 concerning SHIP/SYNOP FM-13, and chapter 5.4 concerning meteorological measurements, for the transmission of wave data and seawater temperature from suitable instruments (buoy). In SHIP/SYNOP FM-13 and meteorological measurements, wind shall be measured in m/s and cloud altitude in metres. Wave energy spectra shall be measured in addition to the parameters described in N-002 (2010) chapter 5.4.
  3. To transfer automatically measured parameters to the Norwegian Meteorological Institute every tenth minute, as is usual from Statoil's facilities. This also applies to wave data, seawater temperature and salinity, with ref. to NORSOK N-002 (2010) chapter 6.1.
  4. To measure ocean currents at several depths and transmit the data to the Norwegian Meteorological Institute, with ref. to NORSOK N-002 (2010) chapter 6.
  5. To submit details on the choice of instruments, siting of instruments, transmission and reporting of data to the Norwegian Meteorological Institute.

Explanation of the terms "order" and "notification of order"
An order is an administrative decision made pursuant to the regulations. Before we issue an order, we generally send a "notification of order" to the affected companies.

A notification of order is neither an instrument nor a notice of sanctions, but a step in the PSA's case processing in which we request the party to assess the factual basis. The notification is only the first step before an administrative decision is made.

An order is a strongly preventive instrument which is legally binding on the recipient
