A key element in our HSE management system is the recording, reporting and assessment of relevant data. HSE performance indicators have been established to provide information on historical trends. The intention is to document quantitative developments over time and to use the information in decision-making aimed at systematic learning and improvement.

Our HSE data is compiled by the business areas and reported to the corporate executive committee, which evaluates trends and decides on the required improvement measures at the corporate level. In addition, the business areas prepare more specific HSE statistics and analyses that are used in their own improvement efforts.

The corporate executive committee submits the HSE results and associated assessments to the board of directors together with the group's quarterly financial results. We communicate key results internally and externally. As a part of this, quarterly HSE statistics are made available in the performance report. HSE data from activities at all assets and projects in which Statoil is the operator are included. Among our group-wide performance indicators for HSE, the following were most closely followed up at group level in 2011:

  • Serious incident frequency (SIF) - The number of serious incidents per million hours worked
  • Technical safety condition (TTS) - Status, observations and actions
  • Climate - Tonnes of carbon dioxide emitted per kilotonne of produced hydrocarbons

Several other performance indicators are being monitored. The key performance indicators are reported quarterly at the corporate level for Statoil employees and contractors. Statistics on our employees' sickness absence are reported annually at the corporate level.

Historical data include figures relating to acquired operations from the acquisition date. Correspondingly, figures relating to divested operations are included up to the divestment date.


The HSE accounting shows the development of the HSE performance indicators over the past five years.

During 2011, our operations account for 142 million working hours (including contractors). These working hours form the basis for the frequency indicators in the HSE accounting. Contractors handle a significant proportion of the assignments that Statoil is responsible for as the operator or principal enterprise.

Statoil's HSE results with regard to serious incidents have shown a positive improvement over the past four years. The overall serious incident frequency (SIF) indicator decreased from 2010 (1.4) to 2011 (1.1). When excluding the Fuel & Retail (SFR) segment, SIF was 0.9 in 2011, compared with 1.3 in 2010.

There was one fatality in 2011. A contractor employee performing maintenance work at service stations in Riga (Latvia) was killed in a traffic accident. In addition, on 6 October, a contractor employee was reported missing from the Visund platform in the North Sea. An extensive search operation, both at the platform, in the sea and on the seabed around the platform was unfortunately unsuccessful.

There has been an increase in the number of total recordable injuries per million working hours (TRIF) in 2011 (4.4) compared with 2010 (4.2). Contractor TRIF at year-end 2011 was 5.1, and Statoil employee TRIF was 3.3. The lost-time injury frequency (injuries leading to absence from work) was 1.9 in 2011, an increase from 2010 (1.8).

The number of accidental oil spills was 376 in 2011 compared with 374 in 2010. The volume was at the same level in 2010 and 2011 (44 cubic metres).
