CRU Role



The CRU is the independent safety regulator for upstream (offshore and onshore) petroleum exploration and extraction activities in Ireland. In order for petroleum undertakings, operators and owners to carry out a designated petroleum activity the petroleum undertaking must first receive a safety permit from the CRU.

The Petroleum Safety Framework

The CRU regulates the industry in accordance with the Petroleum Safety Framework a collection of regulations, written regulatory documents and procedures. The underpinning legislation and key PSF documents can be accessed below, including the CRU Requirements of the Petroleum Safety Framework paper which provides an overview of the CRU safety framework:

Petroleum (Exploration and Extraction) Safety Act 2010

Petroleum (Exploration and Extraction Safety Act 2015

Petroleum Safety (Designation of Certain Classes of Petroleum Activity) Regulations 2013

Petroleum Safety (Petroleum Incident) Regulations 2016

Requirements of the Petroleum Safety Framework

CRU Audit and Inspection System

CER Safety Case Assessment Procedures

Safety Case Guidelines

Further details on the individual components of the Petroleum Safety Framework and the various application and notification forms for industry use are available below.

Safety Permits

In order to obtain a safety permit for a designated petroleum activity, the CRU must assess and accept a safety case(s) for that designated petroleum activity. These safety case(s) are submitted by the operator and owner who will carry out the work.

The table below sets out the safety case(s) that the CRU must accept in order for the related safety permit to be issued:

To assist operators and owners in developing a compliant safety case, the CRU has developed a suite of documents called the Safety Case Guidelines that all existing and prospective operators and owners should be familiar with. In addition, the CRU highly recommends that petroleum undertakings, operators and owners proposing to carry out a designated petroleum activity in Ireland engage with the Petroleum Safety team at their earliest opportunity to get further guidance on the safety case submission and assessment process.

Acknowledgement of Compliance

The CRU have put in place an additional safety case assessment option specifically for non-production installations, whereby rig owners can apply to be assessed for an Acknowledgement of Compliance (AoC) for their non-production installation separate to a safety permit application. An AoC is confirmation that, at the time of the related non-production safety case assessment, the information submitted satisfied the requirements of the CRU Safety Case Guidelines. This AoC can then be submitted as part of a future safety permit application with the intent of making that assessment process more efficient for the owner.

Issued Acknowledgment of Compliance for Non-production Installations

AoC No Owner Non-Production Installation Date Issued
AoC-01 Helix Well Ops (UK) Well Enhancer 28/03/2019
AoC-04a Stena Drilling Ltd. Stena IceMax 14/03/2019
AoC-06 Stena Drilling Ltd Stena Spey 01/04/2021

Levies and Safety Case Fees

The Petroleum Safety Framework is funded in two ways: an annual industry levy and safety case assessment fees. The annual levy issued to the petroleum undertakings, covers all operational costs incurred by the CRU in discharging its regulatory petroleum safety functions, such as operational inspections and incident investigations. Details on how the levy is calculated can be found in the Petroleum Safety Levy Methodology paper.

The safety case fees cover the costs associated with the CRU assessment of a safety case. The owner or operator that submits the safety case is liable for the associated safety case fee. Operators and owners pay an upfront initial safety case fee with their safety case submission and once the CRU assessment is complete the final safety case fee is calculated. Further details can be found in the Safety Case Fees Structure and Methodology paper.

Petroleum Incidents and Confidential Reporting

The Petroleum Safety (Petroleum Incident) Regulations 2016 set out the petroleum incidents that operators and owners are required to report to the CRU. Guidance on the notification of petroleum incidents to the CRU can be found in our Guidance for Notification of Incidents paper

Petroleum incident(s) are required to be notified to the CRU without delay and further details on the incident(s) must be submitted within 10 working days. On notification of a petroleum incident, the CRU may carry out an incident investigation.

To report a petroleum incident, please click here to access the Petroleum Incident Notification Form.

Operators and owners may also report additional incidents to the CRU under section 13S(2) of the Petroleum Safety Act 2015. To report these types of incidents, please use the Section 13S(2) Incident Notification Reporting Form.

Confidential Reporting 

Concerns relating to petroleum safety matters onshore and safety and environmental matters offshore that are linked to a permitted petroleum activity can be notified to the CRU by any person. This can also be done by completing the Confidential Reporting Form. Where requested, CRU will aim to follow up with such notices in a fully confidential manner. Concerns can be notified to the team via any of the CRU main contact details and marked for 'Petroleum Safety', or by sending an email to the Petroleum Safety Team:, with a completed Confidential Reporting Form attached.

Further details on confidential reporting, including reporting by workers, can be found in the Requirements of the Petroleum Safety Framework paper.

Reporting to the European Commission

CRU is required to report specified incidents to the European Commission as set out in Annex IX of Directive 2013/30/EU on offshore safety. Copies of the annual incident reporting to the European Commission can be viewed below.

*On 16 March 2018 Commission for Regulation of Utilities (CRU) was notified of a Petroleum Incident. Approximately 8 kg of unignited natural gas was released over 35 minutes during routine operational activities. This incident is not classed as a major accident hazard as there was no ignition of gas; the system depressed as designed; it occurred outdoors in a well-ventilated area and did not set off any gas detectors within that area. There were no reported injuries to personnel. However, the incident is reportable to EU Commission under 1112/2014 as the amount released was ≥1 kg.

IRF Communique

The International Regulators’ Forum (IRF), met on 4 May 2020 via teleconference to share information about the COVID-19 pandemic and discuss the IRF’s plans for the year ahead. Participants discussed issues that the pandemic has created for the offshore industry in their respective jurisdictions, which include occurrences of illness in offshore workers in some countries, the challenges associated with physical distancing, reductions in personnel on facilities, and other preventative measures in offshore operations.

NSOAF Summary Report Multinational Audit – Maintaining Safe Operations

During 2015 and 2016, the CRU's Petroleum Safety Team together with other members of the Health and Safety Working Group of the North Sea Offshore Authorities Forum (NSOAF), agreed a programme or work concerning the challenges related to maintaining and operating ageing installations in a lower oil price environment. The Group developed a multinational audit (MNA) on the theme of Maintaining Safe Operations with a common set of themes and questions which was then conducted by each regulator on industry in their respective countries

The resulting Report describes the audit process and summarises the findings and learnings from the MNAs. The findings are presented in the report as good or poor practices to indicate areas of improvement and potential for knowledge transfer.

The objectives of the MNA were to ensure that all relevant lessons with respect to maintenance of safety critical barriers learned by the NSOAF members from the audits, are communicated to the industry, and implemented in the North Sea. The overall goal is to evaluate the companies’ ambitions and priorities through managing major accident risk and maintaining safe operations in times of major cost reductions and massive efficiency programs.

Key findings will be shared with representatives from all parties involved in the industry.
