Executive summary

IOGP published Report 456, Process Safety – Recommended Practice on Key Performance Indicators in November 2011 to provide guidance on Key Performance Indicators (KPI) to upstream companies for managing process safety hazards and risks and to prevent unplanned and uncontrolled loss of containment of materials.

2014p, Process safety events – 2014 data, is a further step towards making Process Safety Event (PSE) data and associated KPIs available to all stakeholders. The PSE data presented in this report are based on voluntary submissions from participating IOGP member companies and are not representative of the entire upstream oil and gas industry. Since the collation and reporting of these data is still relatively new, readers are cautioned not to attempt to identify trends at this point.

IOGP started a pilot process of data collection in 2010. Data for the years 2011-2013 have been previously published in Report 2013p.

Participating companies were asked to provide descriptive information for Tier 1 PSE reported for the first time for the year 2014. These, as well as the fatal incident and high potential event reports, were used by the data subgroup of the IOGP Process Safety Subcommittee as the basis for a new, extensive validation exercise to verify that the Tier 1 PSE, fatal incidents and high potential events PSE submitted were correctly categorized. As a result of this process clarification was sought from the submitting companies on a number of the data reports. A need was also identified to make changes to the reporting form which will simplify the validation process in the future. Tier 1 descriptions are at present only for the participating companies and quality assurance/verification of consistency.

The collection of PSE data has progressed, with the number of companies reporting increasing from 26 in 2011 to 32 in 2012, 39 in 2013 and 44 in 2014.

In this report, 2014 data are published together with 2011, 2012 and 2013 data.

A summary of 2011-2014 data can be found in Appendix A.

The Process Safety Events (PSE) data presented are based on the numbers of Tier 1 and Tier 2 PSE reported by participating IOGP member companies, separately for:

• onshore and offshore• drilling and production• activities• consequences• material released

Tier 3 and Tier 4 process safety KPIs are not included in this report but they are being considered for future data requests.

The Tier 1 and Tier 2 data presented have been normalized against work hours associated with drilling and production activities to provide PSE rates.

7Executive summary

Figure 1: PSE Rate – Tier 1 and Tier 2

In 2014, 5 of the reported PSE resulted in 7 fatalities.

The fatal incident and high potential event descriptions that are process safety-related or Process Safety Events from the safety performance indicators report are in 2014pfh, Fatal incident and high potential event report. The intention is to feed back learnings from events and to help organizations to categorize process safety events.

In response to a number of Major Incidents, the oil and gas industry has identified opportunities to improve Key Performance Indicators (KPIs) for monitoring and review within management systems in order to more proactively identify and address weaknesses in risk controls (barriers).

IOGP published Report 456, Process Safety – Recommended Practice on Key Performance Indicators in November 2011. This IOGP report builds on the framework and definitions included in the API Recommended Practice (RP) 754, Process Safety Indicators for the Refining and Petrochemical Industries on process safety indicators, with specific emphasis on their application to upstream oil and gas activities.

IOGP report number 456 and API RP 754 adopt a four-tier framework of KPIs which is illustrated in Figure 2.

Tiers 1 and 2 are predominantly lagging indicators related to Loss of Primary Containment (LOPC) referred to as a Process Safety Event (PSE).

The Tier 1 KPI records events with greater consequence within the four-tier approach.

The Tier 2 KPI records incidents with a lesser consequence.

Key Definitions

Process SafetyProcess safety is a disciplined framework for managing the integrity of operating systems and processes handling hazardous substances. It is achieved by applying good design principles, engineering, and operating and maintenance practices. It deals with the prevention and control of events that have the potential to release hazardous materials and energy. Such incidents can result in toxic effects, fires or explosions, and could ultimately result in serious incidents including fatalities, injuries, property damage, lost production or environmental damage.

Major IncidentAn incident that has resulted in multiple fatalities and/or serious damage, possibly beyond the asset itself. Typically initiated by a hazardous release, but may also result from major structural failure or loss of stability that has caused serious damage to an asset (note this is intended to incorporate terms such as ‘Major Accident’ as defined by UK HSE1).

API RP 754 Tier 1 and Tier 2 KPI definitions and thresholds have been adopted by IOGP with the intent that both indicators are applied across production and drilling operations for the industry worldwide.

The Tier 1 and Tier 2 KPIs include LOPC incidents that are reportable as Process Safety Events (PSEs) if the incident results in any of the consequences shown in Figure 3.

The definitions refer to material release threshold quantities, which are published in Appendix B of IOGP Report 456.

A glossary of terms related to PSE and Process Safety Indicators can be found in 2014s, Safety performance indicators – 2014 data.

Data collectionTier 1 and Tier 2 PSE data were collected from member companies using the PSE data submission form shown in Appendix C. The form is used to report the number of offshore and onshore Tier 1 and Tier 2 PSEs for both drilling and production. The form is also used by companies to report consequences relating to their Tier 1 and Tier 2 PSEs as well as additional information about the material released and the operational activities. Note that a single PSE can result in multiple consequences, so the total number of consequences reported will equal or exceed the total number of PSEs.

IOGP member companies were also asked to submit data on fatalities that resulted from PSEs, i.e. the number of PSEs that resulted in one or more fatalities, as well as the actual number of fatalities (employees and contractors, or third parties).

It is expected that data submissions will mature in both geographical and total work hour coverage with successive years of reporting from 2011. It is hoped that Process Safety Event (PSE) reporting will emulate the extent of personal safety reporting.


Narrative event descriptionsDescriptions and lessons learned for events that had fatal consequences for company or contractor employees are published as IOGP report 2014sf, Safety performance indicators – Fatal incident reports. The narrative descriptions of fatal incidents and high potential events are submitted separately to the process safety event data published in this report, and therefore there can be no direct correlation between them and the data published in this report.

The fatal incident and high potential event reports that are process safety related or process safety events have been taken from reports 2014sf and 2014sh and are published as 2014pfh, Fatal incident and high potential event report. These are narratives of process safety events and of process safety related events where there are significant learnings but the criteria for PSE is not met, e.g. equipment not connected to the process. The intention is to feed back learnings from events and to help organizations to categorize process safety events.

Key Definitions

Primary containmentA tank, vessel, pipe, truck, rail, car, or other equipment designed to keep a material within it, typically for purposes of storage, separate, processing or transfer of gases or liquids. The terms vessel and pipe are taken to include containment of reservoir fluids within the casing and wellhead valving to the surface.

Loss of Primary Containment (LOPC)An unplanned or uncontrolled release of any material from primary containment, including non-toxic and non-flammable materials (e.g. steam, nitrogen, carbon dioxide or compressed air).

Process Safety Event (PSE) – IOGP reportableAn unplanned or uncontrolled LOPC of any material including non-toxic and non-flammable materials (e.g. steam, hot condensate, nitrogen, compressed CO2 or compressed air) from a process, or an undesired event or condition that, under slightly different circumstances, could have resulted in LOPC.

Secondary ContainmentAn impermeable physical barrier specifically designed to prevent release into the environment of materials that have breached primary containment. Secondary containment systems include, but are not limited to, tank dykes, curbing around process equipment, drainage collection systems into segregated oily drain systems, the outer wall of double walled tanks, etc.

11Introduction

Tier 1 Indicator Definition and ConsequencesA Tier 1 Process Safety Event (PSE) is a loss of primary containment (LOPC) with the greatest consequence as defined by this RP. A Tier 1 PSE is an unplanned or uncontrolled release of any material, including non-toxic and non-flammable materials (e.g., steam, hot condensate, nitrogen, compressed CO2 or compressed air), from a process that results in one or more of the consequences listed below:• An employee, contractor or subcontractor “days away from work” injury and/or fatality;• A hospital admission and/or fatality of a third-party;• An officially declared community evacuation or community shelter-in-place;• A fire or explosion resulting in greater than or equal to $25,000 of direct cost to the Company; • A pressure relief device (PRD) discharge to atmosphere whether directly or via a downstream

destructive device that results in one or more of the following four consequences:• liquid carryover;• discharge to a potentially unsafe location;• an onsite shelter-in-place;• public protective measures (e.g., road closure);and a PRD discharge quantity greater than the threshold quantities in Appendix B in any one-hour; or

• A release of material greater than the threshold quantities described in Appendix B in any one-hour period.

Tier 2 Indicator Definition and ConsequencesA Tier 2 Process Safety Event (PSE) is a LOPC with lesser consequence. A Tier 2 PSE is an unplanned or uncontrolled release of any material, including non-toxic and non-flammable materials (e.g. steam, hot condensate, nitrogen, compressed CO2 or compressed air), from a process that results in one or more of the consequences listed below and is not reported in Tier 1:• An employee, contractor or subcontractor recordable injury;• A fire or explosion resulting in greater than or equal to $2,500 of direct cost to the Company;• A pressure relief device (PRD) discharge to atmosphere whether directly or via a downstream

destructive device that results in one or more of the following four consequences:• liquid carryover; • discharge to a potentially unsafe location; • an onsite shelter-in-place; • public protective measures (e.g. road closure); and a PRD discharge quantity greater than the threshold quantity in Appendix B in any one-hour period; or

• A release of material greater than the threshold quantities described in Appendix B in any one-hour period.

Note: Non-toxic and non-flammable materials (e.g. steam, hot water, nitrogen, compressed CO2 or compressed air) have no threshold quantities and are only included in this definition as a result of their potential to result in one of the other consequences.

Note:“Days away from work” injury should be taken to be the same as the IOGP defined Lost Work Day Case (LWDC).

Figure 3: Process Safety Event definitions and thresholds (from IOGP Report 456, extract from API RP 754)


Normalization Tier 1 and Tier 2 PSE have been normalized against work hours associated with process safety events using the following formula for the PSE Rate. Refer to IOGP Report 456, 3.3, for further information.

Data are only included for normalized results where both work hours and process safety event data are reported for the data set and work function.

Database dimensionsThe PSE data collected by IOGP are based on the numbers of Tier 1 and Tier 2 PSE reported by companies, separately for drilling and production activities and subdivided into offshore and onshore data.

PSE relating to sabotage or willful damage are reported separately and are presented in section 2 of this report. They are not included in the results presented in sections 1–7.

The entire IOGP safety performance database, which is used to produce the annual safety performance indicators report (IOGP report 2014s), contains work hours which are split into offshore and onshore work hours and five function categories (defined in the glossary of terms in 2014s, Safety performance indicators – 2014 data as work functions):

• exploration• drilling• production• construction• unspecified

For the purposes of the process safety event database, the only applicable functional categories from the entire IOGP safety performance database are drilling and production, onshore and offshore. The work hours associated with PSE reported in 2011-2014 for drilling and production, onshore and offshore, are shown in Table 1.

Table 1: Related work hours - work hours related to datasets where either Tier 1 or Tier 2 PSE were reported.

The work hours associated with the PSE data reported have been calculated as a subset of the drilling and production function work hours from the entire safety performance database (see IOGP report 2014s, Safety performance indicators – 2014 data) which have been reported for 2011, 2012, 2013 and 2014 by participating companies. The work hours have been used as a reference to provide an indication of scope for the PSE data presented throughout this report.

Work hours have been included where the company has reported associated Tier 1 or Tier 2 PSE data for the country and onshore/offshore location (data set). The associated work hours differ between Tier 1 and Tier 2 because not all companies reported both Tier 1 and Tier 2 PSE data and not all companies reported PSE data for all their global operations.

Some companies that reported PSE data do not split work hours by work function. The reported PSE and work hours associated with these companies have therefore been excluded from the normalized analysis.

25Production results by activity

The Tier 1 and Tier 2 data presented in this section represent both onshore and offshore and are broken down by activity, i.e. whether the event occurred during normal operations, start-up or shutdown. Drilling results are not split by activity, since this would not be meaningful.

‘Other’ is the category used when the event could not be classified under any of the other headings (start-up, normal operations or shutdown).

‘Unspecified’ is used for PSE where the activity has not been provided.

Production Tier 1 and Tier 2 PSE by activity are shown on the next page.

4. Production results by activity


Production Tier 2In 2014, 30 of the companies that reported more than one production PSE provided a breakdown by activity for Tier 2 PSE. The breakdown by activity for 2014 PSE is similar to the breakdown for 2013, 2012 and 2011.

5. Results by consequence

The Tier 1 and Tier 2 data presented represent both onshore and offshore, and production and drilling, combined.

More than one consequence can be associated with each reported process safety event. The consequence classifications are listed in Table 6, from IOGP Report 456, Process Safety – Recommended Practice on Key Performance Indicators. Refer to IOGP Report 456 for further information and threshold tables. The supplement, IOGP Report 456supp, contains examples that can be used as an aid to the interpretation of the guidance.

The analysis in this section shows the number of consequences assigned for the Tier 1 process safety events by consequence. A single PSE can result in multiple consequences, so the total number of consequences reported will equal or exceed the total number of PSEs.


Tier 2Information was provided on the consequence of individual events for 97% of Tier 2 PSE reported in 2014.

Figure 25: Consequences assigned to Tier 2 PSE

Recordable injury 1%

(Table B–2): Material release

An LOPC release of a gas or liquid exceeds the material release threshold quantities in any one hour period

See Tables B–4, 5 or 6 (IOGP Report 456) for Tier 1 threshold quantities

See Tables B–4, 5 or 6 (IOGP Report 456) for Tier 2 threshold quantities

(Table B–3): PRD discharges

A pressure relief device (PRD) discharges either directly to atmosphere or to a destructive device (e.g. flare, scrubber)

Event results in a Tier 1 PSE if the consequence is listed in Table B–1, regardless of the quantity released, or

Event results in a:

• liquid carryover, or

• discharge to a potentially hazardous location, or

• on-site shelter in place, or

• public protective measures,

and quantity discharged equals or exceeds any Tier 1 threshold in Tables B–4, 5 or 6 (IOGP Report 456)

Event results in a Tier 2 PSE if the consequence is listed in Table B–1, regardless of the quantity released, or

Event results in a:

• liquid carryover, or

• discharge to a potentially hazardous location, or

• on-site shelter in place, or

• public protective measures,

and quantity discharged equals or exceeds any Tier 2 threshold in Tables B–4, 5 or 6 (IOGP Report 456)

B–1: LOPC or PRD discharge is recordable as a PSE when it results in one or more of the consequences in this table (irrespective of the amount of material released)

B–2: LOPC is recordable as a PSE, even when no serious harm or damage results, if the amount of material released exceeds specified thresholds

B–3: A PRD discharge event is recordable as a PSE if it results in serious harm or damage, or exceeds the material release threshold quantities while resulting in any of four listed criteria

Table 21: PSE by material released – scope


In this appendix, Tier 1 and Tier 2 PSE rates are shown by company for each of the 3 reporting years in rank order of Tier 1 PSE performance. Company names have been replaced with a 2-letter code. A new code is assigned every year.

44 companies contributed PSE data in 2014. This is in comparison to 52 companies contributing to the safety performance indicators database in 2014.

Data are excluded from PSE rate calculations where work hours are not reported for the data set. In 2014 all of the participating companies provided related work hours and are included in the analysis.

Data relating to Tier 2 PSE were not reported by 2 of the companies in 2014. These are marked ‘No data’ in the tables and graphs below.

Overall refers to the rate for all companies.

The Process Safety Event data presented in this report are based on voluntary submissions from participating IOGP member companies and are not representative of the entire upstream oil and gas industry. Since this is only the second PSE report published by IOGP, readers are cautioned not to attempt to identify trends at this point.

The Process Safety Events (PSE) data presented are based on the numbers of Tier 1 and Tier 2 PSE reported by participating IOGP member companies, separately for:

• onshore and offshore• drilling and production• activities• consequences• material released.
