The challenge

The challenge

For a large offshore gas asset, planners faced a mounting backlog of maintenance, modifications, and well service tasks across dozens of normally unmanned installations (NUIs).


Despite significant cost and effort, the actual execution of work fell short of expectations. The core question was clear: can we get more done through smarter planning, or do we need to invest in more capacity?


Traditionally, planning choices - such as campaign length, sailing frequency, dual manning, or 24-hour operations - were debated subjectively, without visibility into the true trade-offs. Backlogs grew, missions became harder to align, and confidence in the planning process eroded.

Traditionally, planning choices - such as campaign length, sailing frequency, dual manning, or 24-hour operations - were debated subjectively, without visibility into the true trade-offs. Backlogs grew, missions became harder to align, and confidence in the planning process eroded.

Solution

We applied our approach to create an AI-assisted planning environment that mimics the complex decision space of offshore maintenance.


The tool allowed planners to test strategies such as:


  • Longer campaigns vs. more frequent vessel moves.

  • Extending or shortening mission durations.

  • Adopting dual manning or 24-hour operations.

  • Sequencing tasks across NUIs under POB, sailing time, and seasonal constraints.


By framing value drivers (safety, cost, backlog reduction, production impact) and integrating them into the “game,” the AI explored thousands of campaign scenarios. The result: transparent comparisons of alternative strategies, with clear KPIs like utilisation, backlog clearance, and emergency task handling.

Results

Clearer trade-offs

quantified impact of campaign length, vessel moves, and crew strategies.

Higher execution efficiency

revealed opportunities to complete significantly more work with the same resources.

Strategic alignment

provided a structured basis for the company’s leadership to decide whether to optimise planning or expand capacity.
