The Benefits and Drawbacks of Executing Campaign Maintenance on an Offshore O&G Installation

Offshore O&G installations are complex assets that require regular planned preventative and predictive maintenance to ensure safe and efficient operations.

Campaign maintenance, which involves conducting multiple maintenance tasks during a designated period, is a common approach to managing maintenance on these installations.

Our very own Jody Lusher, PBS’ CNS Deputy Asset Manager, explores the pros and cons of executing campaign maintenance…

Key Benefits of Campaign Maintenance:

1. Optimal Resource Allocation: Campaign maintenance allows for efficient resource allocation by grouping multiple maintenance tasks together. This approach reduces downtime and minimises the need for frequent mobilisation of personnel and equipment to the platform. It enables the efficient use of resources and reduces costs associated with multiple mobilisations.

2. Enhanced Planning and Scheduling: By grouping maintenance tasks into a campaign, operators can better plan and schedule activities. This approach enables better coordination between different teams and reduces the risk of conflicting maintenance activities. It also allows for the optimisation of maintenance downtimes and reduces disruption to production operations.

3. Comprehensive Inspection and Repair: Campaign maintenance provides an opportunity to conduct comprehensive inspections and repairs on various components of the assets. By addressing multiple maintenance tasks simultaneously, operators can ensure a thorough assessment of critical equipment, identify potential issues, and mitigate risks effectively. This proactive approach contributes to the overall safety and reliability of the installation.

4. Knowledge Transfer and Training: Campaign maintenance often involves the collaboration of diverse teams, including experienced personnel and specialised contractors. This creates an opportunity for knowledge transfer and training. Less experienced team members can learn from experts, gaining valuable skills and expertise. This knowledge sharing helps to continually develop a competent workforce and improves the overall maintenance capabilities of the team.

Drawbacks of Campaign Maintenance:

1. Extended Downtime: Conducting campaign maintenance can require shutting down process or utility streams on the asset, leading to extended downtime. This downtime can impact production output and revenue generation. Careful planning and coordination are crucial to minimise the duration of the maintenance campaign and mitigate the financial implications of extended downtime.

2. Weather Constraints: Offshore installations are subject to weather conditions that can affect the feasibility of campaign maintenance. Harsh weather, such as storms or heavy fog, may delay or disrupt maintenance activities, further extending the downtime. Weather forecasting and contingency plans are essential to manage these constraints effectively.

3. Increased Complexity and Coordination: Planning and executing campaign maintenance involves managing multiple tasks, teams, and equipment simultaneously. This complexity requires effective coordination and communication between various stakeholders, including maintenance crews, operational personnel, and specialists. Failure to manage this coordination effectively may lead to delays or safety risks.

4. Cost Considerations: While campaign maintenance can optimise resource allocation, it also involves upfront costs. The mobilisation of personnel, equipment, and materials to the offshore asset will require significant planning, coordination and potentially investment. Careful cost-benefit analysis is necessary to evaluate the financial feasibility of campaign maintenance and ensure that the long-term benefits outweigh the initial expenses.

Conclusion:

Campaign maintenance offers several advantages for offshore oil and gas installations, including optimal resource allocation, enhanced planning, comprehensive inspections, and knowledge transfer. However, it also poses challenges such as extended downtime, weather constraints, increased complexity, and cost considerations. Maintenance specialists must carefully assess the pros and cons of campaign maintenance to make informed decisions that prioritise safety, efficiency, and long-term operational success.
