Foreword
Welcome to OGUK’s new-look Health, Safety & Environment Report for 2020. Following the combined HSE Conference in 2019, this report brings together for the first time, data on health, safety and environmental performance across the UKCS in one document. The report examines findings from full-year 2019, as well as key priorities for the sector during 2020 and beyond. As witnessed in most industry sectors across the UK and the world, the COVID-19 pandemic has had a significant impact on oil and gas operations in the North Sea. This year’s report also provides some information about how industry has been working together with public health bodies, regulators and other stakeholders to manage and mitigate the impact of COVID-19. However, this virus should not and will not distract industry from focusing on its key goal of maintaining safe operations while continuing to provide the energy society needs – however challenging that might be. With COVID dominating much of the news headlines, we hope that our report into industry’s 2019 HSE performance provides insight and an opportunity to pause and reflect on the measures taken in controlling the health, safety and environmental risks associated with offshore oil and gas production and to focus on areas that continue to present a risk to our operations. The health of the offshore workforce remains an area of focus. There were 301 emergency medevacs last year, compared with 241 in 2018, with cardiac incidents identified as the main cause - a rise of 42 per cent compared with those in 2018. Medevacs due to injury also rose, from 43 to 56, aligning with the slight increase in significant injuries reported, but medevacs associated with altered mental state decreased from 8 to 6 in number. Although the planned review of OGUK’s Medical Aspects of Fitness for Offshore Work: Guidance for Examining Physicians has been delayed, once completed, the revised
guidance will further assist examining doctors in their assessments of fitness to work offshore. This has the potential to restrict the ability of those with the highest health risks to work offshore, but will provide an important incentive to improve the overall health of the workforce - a goal that industry is committed to. On the safety front, it is encouraging to see that dangerous occurrences and the non- fatal injury rate both fell to their lowest levels in 2019 and, while a single one is too many, it is a testament to industry that continued focus in these areas has resulted in improvement. When looking at the number of hydrocarbon releases, it is still too early to see an impact from the initiatives that have been introduced. The number of these considered reportable under RIDDOR requirements is down year on year, but there are signs of an increase in the three-year rolling average of these. As in previous reports, all releases are shown, including EU reportable releases, and there is a significant rise in the total but to enable a consistent comparison, the focus is better placed on the former. There is no room for complacency, and hydrocarbon release prevention is a key focus area for industry. In aviation safety, 2019 recorded a third consecutive year of accident-free flying in the UKCS, and for the second year running, the five-year fatal accident rate per 100, 000 flying hours remained at zero. As mentioned in our 2019 report, the last fatal helicopter accident occurred off the coast of Shetland on approach to Sumburgh Airport in 2013. The Fatal Accident Inquiry report has been published and noted the significant efforts by regulator and industry to prevent a similar incident in the future. The impact of such a tragic loss of life amongst this close-knit industry community will remain with our colleagues across industry as we continue efforts to improve offshore aviation safety.

Foreword continued
There was a year-on-year increase of chemicals discharged to sea under permit in 2019, related to an increase in drilling activity. 75 per cent of these chemicals were PLONOR, and the number of discharged chemicals labelled with substitution warnings decreased from 2018, constituting less than 5 per cent of the total by mass. The industry takes its responsibilities for environmental management and compliance seriously, as is demonstrated by the performance captured in this report. OGUK continues to work with members to deliver continuous reduction of environmental risk. In November 2019, OGUK held its first ever combined HSE conference with the overarching theme ‘Solving Tomorrow’s Challenges, Today’. Martin Temple gave the keynote speech in which he highlighted the fact that industry leaders from OGUK, IADC, Step Change, together with HSE and OPRED had signed up to the Principles of Process Safety Leadership. These are designed to prevent repeats of events such as Piper Alpha or the 2005 Buncefield Terminal explosion in Hertfordshire. The event concluded with a call for action and the points raised at the conference have formed the basis for OGUK’s HSE future strategic objectives. We hope you find the new format and combination of HSE performance and related issues into one report, both easy to read and informative. Any queries should be directed to OGUK HSE Director Trevor Stapleton at tstapleton@oilandgasuk.co.uk .
Looking now at the environmental performance, the report provides environmental data covering discharges to sea, accidental oil and chemical releases, and waste disposal. This provides the industry an opportunity to review environmental performance indicators and reflect on opportunities to drive further improvement. The UKCS is a mature and complex basin, and the challenges that accompany the production of hydrocarbons mean that the data outlined in this report is equally complex, as the examples demonstrate. Overall, 2019 saw stabilised performance with no significant changes in performance, underlining that good environmental management remains a priority for operators. During 2019, there was a small increase in the volume of produced water discharged to sea, and a larger increase in the concentration and the mass of dispersed oil discharged with produced water, continuing a trend apparent over the preceding three years, but remained well below the 30 mg/l threshold set by OSPAR. An increase in reinjection of produced water of 33 per cent was also seen, with the water being injected into suitable subsurface strata or the reservoir itself to aid enhanced oil recovery. The number of unintended releases from offshore installations has decreased; the total number of incidents was 235 compared to 480 last year. The total mass of oil released has increased slightly in 2019 compared to 2018. The number of chemical releases has also decreased from 2018, as has the total mass released, with 95 per cent of these classified as posing little or no risk (PLONOR) or from the lower risk categories.

COVID-19 Response
In response to the extraordinary challenges posed to industry by COVID-19, OGUK's Pandemic Steering Group (PSG) was formed to ensure effective and coherent action by industry and key stakeholders including OGUK member companies, regulators, Governments, workforce representatives and public health agencies. Focused on four key strategic themes the group supported and led the immediate industry response to the crisis, ensuring the risk of offshore transmission of COVID-19 was minimised, that helicopter transport for personnel and suspected COVID-19 cases were maintained, existing health, safety and environmental risks were managed, and the movement of essential personnel and equipment was maintained, even during the strictest phase of lockdown. The group continues its work to ensure safe operations, security of supply and workforce health and safety are maintained throughout.

Regulation As a high hazard industry, offshore oil and gas is subject to specific industrial legislation that helps manage the health, safety and environmental risks associated with offshore operations, as well as the general suite of HSE legislation applicable to wider industrial activity. Energy Division of the Health & Safety Executive (HSE) has responsibility for regulating all issues affecting safety and health; the Offshore Petroleum Regulator for the Environment and Decommissioning (OPRED) regulates emissions to air and discharges to sea, as well as prevention and control of pollution. The Offshore Safety Directive Regulations 2015, saw the creation of a single Competent Authority (CA) requiring both organisations to work in partnership. Whilst OPRED and HSE still have their separate functions outside the scope of the Directive, the functions of the CA are delivered under a set of common operational arrangements. Safety Cases must be developed and approved for every installation to cover the whole life cycle from design to decommissioning, identifying and quantifying the major accident risks and detailing the measures the installation operator will put in place to manage them to As Low As Reasonably Practicable (ALARP). These are continuously reviewed and updated on a five-yearly cycle ensuring that the arrangements in place remain fit for purpose.
Offshore Oil and Gas – Regulatory Context
Offshore operations and the associated emissions and discharges can only take place once operations have been assessed and a permit or other authorisation is in place setting out the conditions associated with the activity. These emissions and discharges include produced water, chemicals, drill cuttings, greenhouse gas emissions and other atmospheric pollutants, gas flared and vented. Waste generated by upstream oil and gas operations is transferred back to shore for processing. The Civil Aviation Authority regulates offshore helicopter operations, and the Environment Agency (EA) and Scottish Environmental Protection Agency (SEPA) regulate activities involving radioactive materials. The Maritime and Coastguard Agency (MCA) produces legislation and guidance on maritime matters as well as providing the UK's Search and Rescue services and as such, has an involvement in offshore oil and gas operations.
HEALTH, SAFETY AND ENVIRONMENT REPORT 2020

Regulation Requirements relating to reportable incidents are defined by the RIDDOR regulations and the EU Offshore Safety Directive (OSD) Implementing Regulation No 1112/2014. Under this legislation, defined incident types with high potential to cause significant injuries - termed dangerous occurrences and other defined incidents such as failure of a safety critical element must be reported to the HSE. The reporting requirements in the European regulations are broadly aligned with RIDDOR categories, but additional reportable incident categories have been introduced, and the category names are different. The report includes information on both RIDDOR and EU reportable offshore incidents. Environmental emissions and discharges are reported through the EEMS online system, on amonthly, quarterly, bi-annual and annual basis, while any accidental release of materials to sea is reported through the PON1 system.
Offshore Oil and Gas – Regulatory Context continued
Industry must also manage the health and well-being of the offshore workforce effectively, given the remoteness of the worksite and the often- demanding nature of the work they perform. A suite of occupational health- related legislation regulates the offshore working environment to ensure that risks to health are controlled. In addition, it is industry policy that all persons working offshore are examined regularly by a medical professional and deemed medically fit before travelling offshore. The OGUK medical standard and the registered examining doctors who conduct assessments in line with this standard help to ensure that the workforce is medically fit for work offshore.

OGUK facilitates the development of a swift and efficient response in the event of a major unintentional release, minimising the environmental impact, through collaboration between operators, regulators and other stakeholders.
OGUK maintains an Operator focus on Environmental issues, developing strategies and work groups to address emerging trends and support best practice.
The next five-year cycle of risk-based approach (RBA) starts in 2021, assisting operators to improve understanding of and mitigate potential environmental risk associated with discharges.
The Chemicals Technical Group continues to share best practice and engage with regulators and suppliers to ensure the least hazardous chemicals are used.

Oil and gas producers strive to minimise the proportion of their product that isn’t exported to market, using technical and chemical expertise to improve the separation of hydrocarbons from the produced water streams.
The Chemicals Technical Group is working to implement the OSPAR Risk Based Approach to produced water management, identifying risk drivers and looking for mitigation measures.
New installations or reworked production systems are designed to reduce or eliminate produced water discharges entirely.

Strategy
OGUK Strategic Objective – Leading HSE Performance
Part of OGUK’s role is to deliver industry’s strategic objectives, which are set by our members based on industry and society’s requirements. The detailed objectives within the Leading HSE Performance stream are led by and monitored through the health, safety and environmental performance in this report. These objectives broadly translate into four priority areas: ensuring assessment of workforce health takes due account of current medical thinking; elimination or reduction in major accident risks; seeking improvements in all areas of aviation safety, and addressing ongoing environmental issues including supporting the net zero agenda. Driving improvement in these areas demonstrates a clear and ongoing commitment to protect the health and safety of all those working in the oil and gas sector while minimising impact on our environment.
◆ To enhance HSE performance, identify risks and opportunities and encourage shared learning ◆ To actively drive industry response to the HSE's challenge on preventing hydrocarbon releases ◆ To develop enhanced medical health standards and share health promotion activities to improve the health of the workforce ◆ To support the aviation safety agenda by facilitating relevant discussions through the Aviation Safety Technical Group and project managing UKCS aviation safety initiatives as directed by the CAA led Offshore Helicopter Safety Leadership Group ◆ To ensure industry responds to a potential long-term spill scenario, including a delivery model for resource sharing ◆ To develop approach to environmental management (including post-Brexit regulation)
