A new approach to managing environmental issues aims to deliver increased alignment, engagement, transparency, and assurance in relation to managing environmental issues at the Cygnus gas field in the southern North Sea. Jos Tissen and Ian Buchan explain.

Operators are faced with an increasing administrative and cost burden in managing their environmental risks. The Montara blowout and Deepwater Horizon incidents have led to intense scrutiny, exposing conventional management approaches as inadequate.

Also, onshore activities such as hydraulic fracturing attract growing concerns by stakeholders and demand other regulators to review the way they implement environmental regulations. There is therefore a need for all involved to ensure greater transparency and accountability regarding potential environmental risks and their management.

Energy consultancy Xodus Group has developed a new approach for managing environmental issues; which recognizes and proactively manages external expectations, as well as addressing the environmental impact.

This approach offers better alignment with other business objectives and increased confidence in compliance with the existing legislative framework. The approach is currently being applied by GDF SUEZ E&P UK for the drilling program and operational phase of the southern North Sea Cygnus gas development project, see Figure 1.

The approach mirrors the intent of Lord Cullen’s Safety Case review in that it offers a way to maximize the benefits of both prescriptive and goal setting regulation. This is done by creating a platform for open dialogue around important issues, which aims to achieve full integration of environmental management into the operation and maintenance of offshore exploration and production operations.

It is fully aligned with the international standard on environmental management systems ISO14001, which features the continuous improvement concept and includes a commitment to comply with pertinent legislation.

The environmental management plan Due to the way the environmental management plans are developed, they offer a structured approach to creating better alignment in the management of environmental issues and increased confidence in compliance with legislative frameworks and corporate requirements.

Central to the method is a single document detailing the technical scope description, purpose, and methodology, as well as the environmental management planning and implementation.

The document is essential to the company’s environmental management system, as it bridges the gap between operational objectives and stakeholder expectations, and provides an audit trail between high level objectives and individual tasks and responsibilities, depicted in Figure 2.

The outputs from the assessment, as illustrated, are used to inform and populate the tools, systems, and processes that drive and control operations on the asset. The environmentally critical/important equipment are captured within the maintenance management system, with appropriate levels of maintenance and inspection applied to each.

The roles and responsibilities (either onshore or offshore) that are necessary to ensure that the “issue management” strategies are implemented and followed are captured in the job descriptions for each position. The training and competence requirements for each position, in order that these individuals are able to fulfill their roles and deliver on their responsibilities, are captured in the training and competency management system.

The actions that are required to ensure that the plant and equipment on the asset are operated in line with the issue management strategies are then incorporated into the relevant operating procedures.

The focus of the asset management team, as well as those in compliance assurance roles, is therefore on ensuring that maintenance and inspection routines are carried out, personnel are managed in line with HR processes, and operating procedures are followed.

Plan, implement, check and review

The need for environmental protection is generally not disputed and much has been done to reduce industrial and consumer related pollution. However, building an effective environmental management system according to the “plan, implement, check and review” ISO 14001 cycle is not easy and is not as simple as writing a policy and ensuring its execution. Effectively implementing such a system requires alignment with other company commitments, such as structural integrity and financial liability. In reality, enhancing environmental performance is limited by the opportunities for improvement. Forcing through improvements generally results in tension within the organization, lack of alignment and buy-in, and bulky procedures that gather dust on the shelf.

This approach encompasses a side-by-side assessment of the differing societal perspectives by compiling a list of issues (or environmental business risks) from a comprehensive analysis of interactions between activities and environmental and social sensitivities; the equivalent of a safety HAZID (hazard identification study), with a twist.

For each of the resulting 40-60 environmental issues, an objective assessment of ecological impacts is prepared, while being conscious of the limitations of environmental science, such as its struggle to assess cumulative impacts. On the more subjective side of the equation, the expectations of stakeholders, such as their motivation and influence is considered. Finally, legislation and company standards are reviewed to ascertain any differences in these three assessments.

Two main response strategies are distinguished: impact reduction, which is reducing the physical environmental impact by, for instance, reducing the use of resources, by reducing emissions or discharges, or by reducing noise emissions. The other response strategy is risk communication, which is increasing the acceptance of the risk by better explaining the acceptability of the risk, by challenging the motives of stake- holders, or by sharing control with stakeholders. A combination of the two strategies is often required.

Issue management

One answer may be to shift and widen the perspective of environmental management from impact reduction to issue management, as shown in Figure 3. This can have wide-ranging implications.

By changing the objective of environmental management to issue management, everything that is part of the issue is managed under the heading of the issue, including the misalignment of expectations between the company’s HSE department and operational department, and between the operator and the regulator. This explicit representation creates buy-in, and the formulation of realistic management strategies. By broadening the subject, issues become clearer and their management more focused, while confidence in meeting regulatory requirements and expectations also increases. This can be demonstrated in the following three examples:

A risk based approach

The approach aligns with the Oil & Gas UK Environmental Assurance Plan (EAP) initiative. This results in a different management structure where the system is built from the bottom up, i.e. developing issue specific management strategies with input from the line, identifying tasks and responsibilities, and collating those in procedures as and when required. It is therefore specific and responds to real-time changes, and can be applied

at any stage of the project development process, from inception to decommission- ing, and is fully aligned with ISO 14001.

The most recent example of the application of this approach involved a new regulator (NOPSEMA) in Australia, which had been rejecting a large number of environmental approval applications. The new approach was applied and plan approval given almost instantly. The main barrier encountered before using the approach was to satisfactorily demonstrate to NOPSEMA that proposed operations’ environmental impacts were reduced to a level “As Low As Reasonably Practicable” (ALARP). The approach allowed attention to be concentrated on the issues that deserved to be formally addressed (either due to scientific, industry, regulatory or stakeholders concerns), and how they could be managed. ALARP became the by-product of the issue management dialogue.


The concept of a risk-based approach to managing health and safety is not new to the oil and gas industry. A key recommendation from the Piper Alpha inquiry was to move the industry from a largely prescriptive safety regime to a goal setting one. The subject approach facilitates a similar shift for the management of environmental issues.

Whilst this is still work in progress, the positive feedback received to date during the process of implementing the 

approach gives confidence that it will deliver unparalleled levels of alignment, engagement, transparency and assurance on the management of environmental issues pertinent to the Cygnus Field across GDF SUEZ E&P UK, regulatory bodies and other stakeholders.
