Late life management and decommissioning come sharply into focus at the final phases of the asset life cycle.

The drivers in these final phases are very different to on-going operations. Often, a ‘project’ rather than ‘operations’ mind set and culture is required. By its very nature any decommissioning solution needs to be highly cost-effective, which means it also needs to be asset specific.

At Petrofac we utilise the breadth and depth of our service capability across the asset life cycle to support our clients with their specific decommissioning needs.

This ranges from engineering services including conceptual and FEED solutions; well engineering services focused around right-sized well project management and plugging and abandonment capabilities through to a complete range of operations-led asset solutions.

We can deliver a single discrete service through to a complete managed solution. We can also work in alignment with the wider supply chain to offer a full turnkey service for decommissioning; enabling our clients to focus their time and resource elsewhere in the portfolio.

In everything we do, our emphasis is on creating innovative Late Life Asset Management (LLAM) and timely decommissioning services.

We understand the benefit that early intervention can bring and our aim is to help our clients optimise and execute the eventual decommissioning solution chosen.

We have a reputation for creating tailored, asset-specific strategies that are aligned with our clients’ strategic aims. Whether assets are on or offshore, fixed or floating we have the skills and track record to support our clients no matter where they are on their decommissioning journey.

Duty Holder in decommissioning: designed for non-producing assets, we can tailor our Duty Holder model to help clients reduce OPEX and ABEX through manpower optimisation, maintenance simplification and the use of bespoke shared services and control management systems.

LLAM Duty Holder: a model focused on helping our clients effectively push out the cessation of production date and extend field of life. We work with operators to effectively eliminate waste and inefficiencies to safely increase production and uptime. By engaging with us at the earliest stage, we can use our asset knowledge to extend the life of the facilities and provide a range of early-interventions and cost-effective measures to reduce the eventual cost of removal.

We can take a ‘park and defer’ approach, applying cost-effective de-manning and remote intervention services as well as safety case management for late life assets, where a decommissioning strategy has still to be determined.

Engineering: from concept and feasibility studies to enhanced production methodologies, cost estimating and options analysis, our capability is extensive. It includes operations, engineering, (de)construction and removal considerations, structural and marine assurance, lifting analysis and technical safety spanning topsides, jackets, pipelines, subsea pipelines and terminals. Our solutions are fully scalable, enhanced by our offshore construction experience. Decommissioning cost estimates are prepared using an in-house software tool that allows for easy comparison of competing asset retirement technologies.

Optimised maintenance: using a structured methodology for the assessment of maintenance and inspection activities, we can help operators optimise an asset’s workload and workforce during late life. The process engages stakeholders whilst optimising resources. Using our asset management software, BuildME™, we can ensure that safety, environmental and business risks are addressed throughout the asset life cycle by managing maintenance and inspection activities as required. BuildMe™ allows for a number of different decommissioning scenarios to be assessed simultaneously.

Well engineering: from feasibility through well construction and plug and abandonment, our capability covers decommissioning cost estimation, studies, detailed design, (de)construction, asset removal and project management.

Supply chain management: we have an extensive vendor and subcontractor network, including experience with heavy lift vessel selection, management, waste and logistics.

Emergency Response and Crisis Management (ERCM): we have over 20 years’ experience developing, implementing and maintaining clients’ training and crisis-management systems. The service includes preparation of emergency response plans and procedures for dealing with major accident hazards on high-risk sites.

HSE: as an organisation which provides installation, well, pipeline and COMAH operator from operations into decommissioning, we maintain full capability for health, safety and environmental protection. Our competence spans occupational, industrial and process safety relevant to operations and maintenance, engineering and construction and achieving regulatory compliance. As Duty Holder we maintain positive relationships with regulatory bodies.

Our technical safety specialists will prepare Safety Cases and undertake risk assessments and studies for the full life cycle of an asset, including decommissioning. Our environmental specialists prepare Oil Pollution Emergency Plans and make all relevant regulatory submissions for permits and consents. We can also manage specialist scopes such as the preparation of, or contribution to, decommissioning programmes, comparative assessment, environmental impact assessment, risk analysis, and waste management duty of care.
