Mastering Turnaround Cost: Tackling Regulations and Implementation

Turnaround cost reduction tops oil-and-gas priorities, yet operators lack a repeatable path. When they hear of 20% savings, 50% scope cuts, and 16% shorter shutdowns, one question arises: How, without stretching teams thinner?”

In our previous article, we outlined the Maintenance Trap and the four-pillar playbook to break it. This article shows how it can be done by: focusing on what can be changed within existing regulatory frameworks, building a forward‑deploy implementation model that works around bandwidth constraints, and starting with the highest‑impact integrity problems first. The goal is not just to highlight the potential savings, but to make the path to a proven 20% turnaround cost reduction visible, measurable, and achievable within the realities of an already stretched organization.

Before any serious conversation about turnaround cost reduction gets very far, the same question comes up: Will this work within our regulatory framework?

Working with a Spanish operator gave us a clear answer to that question. Their case clearly demonstrated that even the most prescriptive inspection regime can still be optimized within the rules.

The Spanish regulatory framework is among the most prescriptive in Europe. Key requirements include:

With that baseline, the natural reaction is that there is nothing left to optimize. In practice, however, even the strictest frameworks leave room for smarter inspection planning, better scope definition, and more focused integrity work.

For this operator, the 20% turnaround cost reduction came from a combination of risk‑based and integrity‑driven levers:

By working those levers, the operator achieved significant reductions in turnaround costs, scope, and shutdown duration. Not by working around the rules, but by working smarter within them. Regulatory requirements stayed exactly as they were. The value came from changing how the work was done inside those boundaries, not from changing the boundaries themselves.

Several European countries enforce similar levels of regulatory rigidity. For instance, the Netherlands requires TCD/KFD-aligned inspections, Germany follows BImSchG and pressure-equipment regimes, France adheres to ASN-influenced national safety regulations, and the United Kingdom applies HSE-aligned safety and pressure-equipment regimes.

North America is no exception. Canada enforces rigorous pressure equipment oversight for the oil and gas sector through provincial safety regulations which mandate compliance with CSA B51, CSA Z662, and ASME-based construction and in-service inspection standards.

In Asia, countries such as India (with national safety and environmental codes), Thailand, Singapore, and Vietnam enforce similarly tight controls on safety and environmental requirements.

The geography changes, but the conclusion remains the same: the boundaries define what cannot change. Everything within them is an opportunity.

Spain proved optimization within rules. The Netherlands unlocked more by securing TCD (Technical Committee for Pressure Equipment) approval for IMS SRBI and RBI 581. That approval did not come by default. We built it through direct engagement, rigorous methodology, and a track record that regulators could verify.

Methodology approval opened the door. What followed was the harder test. We then applied this approach to some of the most tightly regulated equipment in the industry. On three highly regulated gasifiers, we defended RBI before the regulator and secured approval. This enabled risk-based inspections only when required, not on obligatory fixed intervals.

Here’s how we accomplished it in practice:

Regulatory approval defines what is possible. A structured execution process is what makes it repeatable. That is where scope optimization begins.

For most operators, the strategy is not the hardest part. The hardest part is implementing a new system in an organization that is already running at full capacity and has a low tolerance for anything that looks like another major program. Knowing what needs to change and having the capacity to make the changes are two very different things.

Most implementations fail not because the technology is wrong but because the people running them are already doing three other things. For this reason, we’ve built our forward‑deploy model around that reality. Rather than handing over a system and expecting an overstretched team to make it work, we embedded with the operator’s team and take ownership of the heavy lifting: configuration, onboarding, and coaching.

In that project, the operator did what only they can do, providing access and making decisions, drawing on the people who know the asset best: representatives from inspection, corrosion, reliability, maintenance, and IT.

We ran the collaboration through weekly structured touchpoints that kept the work moving without pulling subject matter experts away from their day jobs. Nine months in, teams measured tangible results. The rollout targeted the highest-impact areas first and scaled by site, while tracking KPIs from month one onward.

Integrity problems vary widely in impact. Knowing which ones to tackle first separates programs that deliver quick wins from those stuck in complexity.

Across refineries, these integrity challenges tend to cluster around the same pain points:

We began our work with the major European refinery operator by establishing which of these problems to tackle first. After all, trying to address everything at once is a reliable way to make no meaningful progress on any of it.  So we mapped each challenge against two dimensions: how frequently it occurs and how significant its business impact is. That combination determined where to start.

As shown in the figure below, high-impact, recurring problems demanded immediate action. Moderate-impact, high-frequency issues delivered efficiency wins that teams captured without major organizational effort. High-impact but less frequent problems became strategic priorities that teams plan for later. Meanwhile, teams deprioritized everything else until the foundations stabilized.

Integrity, maintenance, TA (Turnaround), and IT departments jointly confirmed those priorities to ensure the starting point reflected operational reality rather than a single team’s view. Furthermore, this alignment set a solid collaborative foundation. The rollout began in the top-right quadrant to deliver quick wins early. This approach avoided overloading available resources. It then expanded systematically across assets only as governance and adoption stabilized.

We designed the implementation timeline for the major European refinery operator to achieve a measurable impact in 6 to 9 months. As mentioned earlier, Cenosco drove the heavy lifting while the refinery retained full control over decisions.

The milestones were specific and time-bound.

We embedded change management throughout the journey, through training, change champions, adoption health checks, and governance coaching. This was essential, as technical delivery alone does not create lasting change. The road from baseline to validated ROI was not just about tools and data, but about aligning people, processes, and governance behind a single, risk‑based view of integrity.

This is not a methodology that works only at scale or only under ideal conditions. Any asset‑intensive organization looking to reduce turnaround costs, improve integrity visibility, and build a program that holds up under operational and regulatory pressure can adopt the same structured approach we used for the major European refinery operator.

Once IMS is implemented, the plant’s turnaround and integrity teams follow a structured process to optimize turnaround scope for each asset. The steps are sequential and build on each other:

The result is a turnaround scope that is built on evidence, not inherited from the previous cycle.

Risk-based turnarounds are no longer a future ambition. The Spanish and Dutch cases in this article show that the regulatory path is navigable, the implementation model works around organizational constraints, and the results hold up across geographies and asset types. Operators who apply the four pillars consistently achieve scope reductions of up to 50% and overall turnaround cost reductions of up to 20%, with early ROI typically visible well within the first year.

Cenosco IMS (Integrity Management System) has been applied across more than 300 assets in 40+ countries over 25 years. The regulatory complexity, the organizational constraints, the integrity challenges have all come up before.
