Addressed to no body recorded · Full record

2: Objectives the Safety Case must demonstrate

Recommended

The Safety Case should demonstrate that certain objectives have been met, including the following:- (i) that the safety management system of the company (SMS) and that of the installation are adequate to ensure that (a) the design and (b) the operation of the installation and its equipment are safe (paras 17.36 and 21.56-57); (ii) that the potential major hazards of the installation and the risks to personnel thereon have been identified and appropriate controls provided (para 17.37); and (iii) that adequate provision is made for ensuring, in the event of a major emergency affecting the installation (a) a Temporary Safe Refuge (TSR) for personnel on the installation; and (b) their safe and full evacuation, escape and rescue (paras 17.37-38, 19.109, 19.157 and 20.8).

Addressed to no body recorded · Full record

3: Safety management system content

Recommended

The SMS should be in respect of (a) the design (both conceptual and detailed) of the operator’s installations; and (b) the procedures (both operational and emergency) of those installations. In the case of existing installations the SMS in respect of design should be directed to its review and upgrading so far as that is reasonably practicable (para 21.56). The SMS should set out the safety objectives, the system by which these objectives are to be achieved, the performance standards which are to be met and the means by which adherence to these standards is to be monitored (para 21.56). It should draw on quality assurance principles similar to those stated in BS 5750 and ISO 9000 (para 21.58).

4: Contents of the Safety Case

Recommended

In furtherance of the objectives set out in para 2 above, the operator should be required to set out the following in the Safety Case:- (i) A demonstration that so far as is reasonably practicable hazards arising from the inventory of hydrocarbons (a) on the installation, and (b) in risers and pipelines connected to the installation both in themselves and as components of the total system of which they form part have been minimised (paras 19.17 and 19.20). (ii) A demonstration that so far as is reasonably practicable the exposure of personnel on the platform to accidental events and their consequences has been minimised (para 17.37). (iii) A demonstration by quantified risk assessment of major hazards that the acceptance standards have been met in respect of risk to the integrity of the TSR, escape routes, embarkation points and lifeboats from design accidental events and that all reasonably practicable steps have been taken to ensure the safety of persons in the TSR and using escape routes and embarkation points (paras 17.38 and 19.157). (iv) A demonstration that within the TSR there are facilities as specified by the operator which are adequate for the purpose of control of an emergency (para 19.182). (v) A fire risk analysis, in accordance with recommendation 49 below (para 19.90). (vi) An evacuation, escape and rescue analysis, in accordance with recommendations 73-75 below (para 20.9).

5: Design accidental events and acceptance standards

Recommended

For the purposes of the demonstration referred to in para (iii) of recommendation 4, the accidental events are to be identified by the operator. A design accidental event is an event which will not cause the loss of any of the following:- — the integrity of the TSR, — the passability of at least one escape route from each location on the platform, — the integrity of a minimum complement of embarkation points and lifeboats specified for personnel in the TSR, and — the passability of at least one escape route to each of these embarkation points, within the endurance period specified. Events more severe than this are referred to as residual accidental events (para 19.160). The acceptance standards for risk and endurance time should be set before the submission of the Safety Case. Standards should be set by reference to the ALARP principle. For the time being it should be the regulatory body which sets these standards. The operator should define the conditions which constitute loss of integrity of, and the standards of protection for, the TSR and escape routes to the TSR and from the TSR to the embarkation points; and should specify the minimum complement of embarkation points and lifeboats for the TSR (paras 19.158-159).

6: Temporary Safe Refuge as accommodation

Recommended

The TSR should normally be the accommodation (paras 19.156 and 19.161). In the case of existing installations any requirement for the upgrading of the accommodation, escape routes and embarkation points should be determined on the basis of the Safety Case (para 19.165).

Addressed to no body recorded · Full record

7: Safety Case specification of TSR and escape

Recommended

In connection with the above the Safety Case should specify the following:- In respect of the TSR- — its function — the conditions which constitute its integrity — the conditions for integrity of its supporting structure — the events in which and the period for which it is to maintain its integrity (paras 19.157-158). In respect of escape routes to the TSR and from the TSR to the embarkation points- — the conditions which constitute their passability — the conditions for integrity of their supporting structure — the events in which and the periods for which they are to maintain their passability (provided that for each location on the platform there should be a minimum of two escape routes to the TSR, at least one of which should remain passable for the period) (para 19.164). In respect of embarkation points and lifeboats- — the number and location — the conditions for their integrity and that of their supporting structure — the events in which and the periods for which they are to maintain their integrity — the minimum complement for the TSR (para 19.164).

8: Safety Case before installation operates

Recommended

No fixed installation should be established or maintained in controlled waters; and no mobile installation should be brought into those waters with a view to its being stationed there or maintained in those waters unless a Safety Case in respect of that installation has been submitted to and accepted by the regulatory body (para 17.41).

Addressed to no body recorded · Full record

9: Date for submitting Safety Cases

Recommended

As regards existing installations the date for submission of the Safety Case should be laid down by regulation. There is an urgent need for the submission of Safety Cases, but the date should be selected by the regulatory body. The regulatory body should have the power, in the event of the failure of an operator to submit an acceptable Safety Case, to require the operator to take whatever remedial action it considered necessary, including requiring the installation to be shut down (paras 17.44-45).

Addressed to no body recorded · Full record

10: Updating the Safety Case

Recommended

A Safety Case should be updated:- (i) After a period of years from its last assessment (not less than 3, not more than 5, years). (ii) At the discretion of the regulatory body on the ground of a material change of circumstances, such as a change of operator, the occurrence of a major emergency (including one in which there is a precautionary evacuation), a major technological innovation or the discovery or better understanding of a major hazard. However, provision should be made in order to avoid the need for more than one Safety Case to be updated by an operator at the same time; and to enable the regulatory body to postpone the automatic updating where it has recently required a discretionary updating (para 17.46).

Addressed to no body recorded · Full record

11: Modifications and the Safety Case

Recommended

As regards modifications to installations or their equipment or procedures, the operator should, before putting the modification into effect, ascertain what effect, if any, it has on the relevant components of the Safety Case. An operator should be required to report to the regulatory body all intended modifications which meet criteria set by the regulatory body, with a view to discussing with the regulatory body whether and to what extent a review of the Safety Case is required (para 17.47).

Addressed to no body recorded · Full record

12: Regulations, guidance notes and Safety Cases

Recommended

For the time being the acceptance by the regulatory body of Safety Cases should not be regarded as justifying the revocation of regulations or the withdrawal of guidance notes (para 17.67). Where an operator proposes to meet the objectives of a Safety Case by means which are not in accordance with regulations or guidance notes the justification for such a course should be set out in the Safety Case. For the assistance of operators the regulatory body should publish as soon as possible, and thereafter update in the light of experience, a list of the individual regulations relating to an installation and its equipment in respect of which it is prepared to grant exemption in the light of a satisfactory demonstration in a Safety Case; and to do likewise in regard to guidance notes (para 17.67). In due course the existing regulations of a detailed prescriptive nature should be reviewed with a view to their revocation or replacement by regulations which set objectives. However, it is anticipated that there will continue to be even in the long term a case for some detailed prescriptive regulations (paras 17.63, 17.67 and 21.67).

13: Preliminary assessment at Annex B consent

Recommended

The regulatory body should discuss with the industry whether it is desirable and practicable that at the stage of the application for Annex B consent (or its equivalent) there should be a procedure for submission by operators of a preliminary assessment of matters relevant to a Safety Case and for the acceptance of this assessment being a prerequisite for the granting of Annex B consent (para 17.43).

Addressed to no body recorded · Full record

15: Regulatory body review and inspection

Recommended

The regulatory body should be required regularly to review the operator’s audit on a selective basis; and itself to carry out such further audit as it thinks fit; and by regular inspection verify that the output of the SMS is satisfactory (para 21.60).

Addressed to no body recorded · Full record

16: Review of the certification system

Recommended

The regulatory body should consider (i) after the introduction of requirements for the demonstration of SMS and auditing of compliance with it; and (ii) after experience in the operation and effectiveness of such requirements whether and to what extent it will be appropriate to retain the present system of certification (para 21.64).

Addressed to no body recorded · Full record

17: Goal-setting regulations and guidance notes

Recommended

(i) The principal regulations in regard to offshore safety should take the form of requiring that stated objectives are to be met (referred to as “goal-setting regulations”) rather than prescribing that detailed measures are to be taken (para 21.67). (ii) In relation to goal-setting regulations, guidance notes should give non-mandatory advice on one or more methods of achieving such objectives without prescribing any particular method as a minimum or as the measure to be taken in default of an acceptable alternative (para 21.67). (iii) However, there will be a continuing need for some regulations which prescribe detailed measures (para 21.67).

Legacy & impact

AI-generated · 26 Mar 2026
The Cullen Inquiry examined the Piper Alpha disaster of 6 July 1988, in which 167 men died following an explosion and fire on the North Sea oil platform. Lord Cullen's report, published in November 1990, made 106 recommendations for improving offshore safety.

The inquiry's findings led to substantial reforms in offshore safety regulation. In 1991, regulatory responsibility transferred from the Department of Energy to the Health and Safety Executive, addressing the conflict between promoting oil production and regulating safety. The Offshore Installations (Safety Case) Regulations 1992 introduced a fundamental change in regulatory approach, requiring operators to produce safety cases demonstrating they had identified major hazards and reduced risks to as low as reasonably practicable (ALARP).

This shift from prescriptive rules to goal-setting regulation has been adopted internationally and is frequently cited as a landmark in industrial safety regulation. The Health and Safety Executive's 2001 review found significant improvements in offshore safety culture and substantial reductions in fatality rates following these reforms. Step Change in Safety, established in 1997, continues to operate as an industry body promoting safety improvements.

The Piper Alpha Inquiry stands as one of the most consequential UK public inquiries, with its safety case approach influencing industrial safety regulation globally. The comprehensive acceptance and documented implementation of its recommendations distinguishes it from many other public inquiries.

Key legislation

Offshore Installations (Safety Case) Regulations 1992 Primary ↗
Introduced a goal-setting, risk-based safety case regime for all offshore installations, requiring operators to demonstrate ALARP risk reduction.

Implementation reviewed by

Health and Safety Executive (offshore safety review) (Jan 2001)
Ten-year review of the safety case regime introduced after Piper Alpha. Found that the goal-setting regulatory approach had been effective, with significant improvements in offshore safety culture and a substantial reduction in fatality rates. Identified scope for further improvement in ageing infrastructure management.

Influence & connections

Led directly to Offshore safety regulation
The Piper Alpha Inquiry established the safety case regulatory model for offshore oil and gas, which has been adopted internationally as a landmark in industrial safety regulation.
Influenced by Flixborough Inquiry
Flixborough established the principle of Management of Change in process safety. The Piper Alpha inquiry built on this foundation to create the safety case regulatory model for offshore installations.
