What are the emerging technologies and innovations for offshore decommissioning and asset life extension?

1 Robotics and automation

One of the key drivers of offshore decommissioning and asset life extension is robotics and automation, which can reduce human exposure to hazards, improve operational efficiency, and lower costs. For example, autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) can perform inspection, maintenance, and repair tasks in harsh and inaccessible environments. Similarly, drones and sensors can collect data and monitor the condition of offshore structures and pipelines. Additionally, digital platforms and artificial intelligence (AI) can enable data analysis, decision making, and remote control of offshore operations.

2 Circular economy and reuse

Another emerging trend in offshore decommissioning and asset life extension is the adoption of circular economy principles and practices, which aim to minimize waste and maximize value. For instance, some offshore platforms and equipment can be reused or repurposed for alternative uses, such as renewable energy, aquaculture, or artificial reefs. Moreover, some materials and components can be recycled or recovered, reducing the environmental impact and the need for new resources. Furthermore, some operators and contractors are collaborating to share best practices, knowledge, and assets, creating synergies and efficiencies.

4 Enhanced recovery and extension

A fourth technology in offshore decommissioning and asset life extension is the enhancement of oil and gas recovery and the extension of the productive life of offshore fields. This can be achieved by using various methods and techniques, such as water injection, gas injection, chemical injection, thermal recovery, or hydraulic fracturing. These methods can increase the pressure, flow, and recovery rate of the reservoirs, making them more profitable and efficient. Additionally, some operators and contractors are investing in new exploration and development activities in mature or marginal fields, using advanced seismic and drilling technologies.

5 Subsea processing and transportation

A fifth innovation in offshore decommissioning and asset life extension is the development of subsea processing and transportation systems, which can reduce the need for surface facilities and infrastructure. For example, subsea separation, boosting, compression, and injection systems can process the oil and gas streams at the seabed, improving the quality and performance of the production. Likewise, subsea pipelines, terminals, and storage systems can transport the oil and gas from the offshore fields to the onshore markets, reducing the emissions and costs. These systems can also enable the development of remote or deepwater fields, expanding the offshore potential.

6 Green decommissioning and transition

A sixth trend in offshore decommissioning and asset life extension is the integration of green decommissioning and transition strategies, which aim to reduce the environmental footprint and support the energy transition. For example, some operators and contractors are using renewable energy sources, such as wind, solar, or wave power, to power their offshore operations, reducing their dependence on fossil fuels and their greenhouse gas emissions. Similarly, some offshore platforms and equipment can be converted or adapted to support renewable energy generation or storage, creating new opportunities and value. Moreover, some operators and contractors are diversifying their portfolios and skills, investing in low-carbon technologies and solutions.
