Hydrocarbon Releases (HCRs)5

5 Major, Significant and Minor Release Severity Classifications are described on the HSE Website in the Hydrocarbons Release Database HELP facility.

Hydrocarbon releases are regarded as potential precursors to major accidents if ignited, and HSE monitors the number of major and significant hydrocarbon releases as a key performance indicator (KPI) of the offshore industry’s effectiveness of process health and safety management on offshore installations.   Based on provisional figures for 2010/11:

RIDDOR reportable HCRs are unintended releases of petroleum gas or liquids from an offshore installation which either result in fire or explosion or require action to prevent or limit the consequences of a potential fire or explosion if ignited, or which have the potential to cause death or major injury.  During 2010/11 five releases (i.e. 3% of all reported HCRs) were reported as ignited events.

Few of these HCRs gave rise to incidents which could, in whole or in part, be considered as "oil spills"6.  The number of the liquid based HCR incidents where a quantity of hydrocarbon liquid was released to the sea in 2010/11 was very small - seven in total – with the amounts ranging from minimal to 500kg. 

Supplementary data on hydrocarbon releases reported under RIDDOR are voluntarily reported to HSE by operators on Form OIR/12.  Figure 6 is based upon those HCRs for which Form OIR/12 have been processed. Final figures may be subject to variation depending on when OIR/12 returns are made to HSE).

6 Dept. of Energy and Climate Change (DECC) Petroleum Operations Notice 1 (PON1) report form is used by operators to report all releases of oils and chemicals of whatever size to sea from offshore installations and pipelines under the Offshore Petroleum Activities (Oil Pollution Prevention and Control) Regulations 2005 (OPPC)(as amended) and Offshore Chemicals Regulations 2002 (OCR) (as amended) to DECC and other authorities. For details of spills to sea refer to DECC.

Oil & Gas UK key performance indicators on Verification & Safety Critical Maintenance

Since 2008, Oil and Gas UK (O&GUK) have been collecting voluntary industry data, monitoring two additional offshore KPIs to track industry performance in key areas of major hazard prevention.  These two KPIs relate to the level of outstanding safety critical maintenance (KPI-3) and to the level of issues raised by operators’ 3rd party verification (KPI-2) of the performance of its safety critical elements (and how findings are subsequently closed out).  Whilst this data is not collected or validated by HSE, these two additional cross-industry KPIs are included in this HSE Offshore Safety Statistics Bulletin for the first time to provide useful additional evidence of the offshore industry’s major hazard management performance.

O&GUK monitoring activity is on a quarterly basis.  Headline findings relating to these two KPIs are:

Notes:

This bulletin provides provisional data for 2010/11.  A further breakdown of the headline information contained in this Bulletin will be provided later this year in the annual Offshore Injury and Incident Statistics Report, produced as part of the HID Statistics Report (HSR) series of publications.

Interpretation of trends over a short period of time should be treated with caution, particularly when addressing small data populations.
