How Cosasco Cut Engineering Work Time by 80%

Cosasco has been a global leader in corrosion monitoring and measurement for over 70 years. Their products — access fittings, retrievable instruments, and monitoring systems — are installed on oil and gas pipelines, offshore platforms, and processing facilities around the world. In industries where corrosion can mean catastrophic failure, Cosasco's solutions are part of how operators keep critical infrastructure safe and running.

Winning and delivering projects in that environment requires navigating enormous volumes of customer documentation and producing precise engineering outputs reliably, across a global team. When Cosasco started exploring AI, they were looking for something that could match that standard.

The Problem: A Documentation Stack Nobody Could Fully Tame

Every major oil and gas project comes with a layered specification problem. The facility owner has requirements. The engineering firm managing the project adds another layer on top. The physical location (Abu Dhabi, the Arctic, or Morocco, for example) adds a third shaped by regional standards and environmental conditions. A single company with assets in multiple regions might have entirely different requirement sets in play at once.

For Cosasco's bidding and engineering teams, correctly interpreting all of that documentation was one of the most time-consuming and error-prone parts of the business. Reviewers would work through thousands of pages, miss a requirement buried in a site-specific annex, and discover the gap late in a project — after manufacturing, when fixing it meant delays, rework, and damage to the customer relationship. Leadership decided to look for a better approach.

Why Cassidy

The team evaluated several options. CPQ tools and soft-matching platforms could retrieve prior answers but couldn't reason through novel situations. Other platforms required significant engineering investment to stand up. Cassidy offered the depth they needed with a much faster path to something working — and the Cassidy team was involved from day one, helping build, test, and refine rather than handing over a product and stepping back.

"There wasn't anybody else that had anything quite like what you did out of the box. You helped us get to a workable, viable product almost instantly. The collaboration was really great."

— Eric Goodyear, Engineering Lead, Cosasco

The Engineering Agent: 80% Less Time, With Better Output

The first and most technically demanding application was a dedicated engineering agent built on the foundational standards governing the industry: ASME, ASTM, ISO, API. These are immutable frameworks, fixed for decades, that underpin almost every technical decision Cosasco's engineers make. With those standards as its reasoning base, the agent can work through calculations, review compliance, cross-reference requirements, and write code to perform specialized calculations such as wake and drag force analysis — the way a senior engineer would, at a fraction of the time.

The first real test was a lethal service conformity assessment on a valve. The engineering team let the agent handle it. The output was 17 pages of in-depth calculations cross-referenced against multiple standards, and when they reviewed it, there wasn't a single error — no miscalculations, no wrong cross-references. A task that would have taken roughly 40 hours manually was completed in eight.

"I was able to go through and do a lethal service conformity assessment for a valve which ended up being 17 pages of in-depth calculations. Not a single mistake, not a single wrong cross-reference, not one."

— Eric Goodyear, Engineering Lead, Cosasco

That five-to-one ratio has held ever since. Two more examples:

An H1 assessment. A technical assessment that would normally take a senior engineer around 40 hours was completed in eight — the same ratio as the conformity assessment, now repeating consistently across different types of engineering work.

"An H1 assessment for what I was doing would probably take me 40 man hours. I think I did it in a day in eight, so about five to one. I'd say that tends to be pretty on the nose — you save about 80% of the time where it's applicable."

— Eric Goodyear, Engineering Lead, Cosasco

A $600,000 inspection test plan. On a large, complex order with hundreds of line items, the team produced a complete inspection test plan for a high-scrutiny customer. A task that would have taken three to four days was done in one, and the customer accepted it because every justification was grounded in their own specifications.

"I was able to get a customer that would normally be quite intractable to agree to something very good — because it justified every answer against their own specifications."

Expanding Across the Business

Once the engineering agent was established, Cosasco expanded Cassidy into other parts of the business.

Quoting and compliance. The bidding team embedded Cassidy across the quoting workflow — covering quote verification, technical clarification, contract review, and project handoff documentation. One of the most valuable applications is comparison review: once a bid is submitted, the team runs it against the customer's documentation to catch discrepancies before they surface downstream. The Middle East bidding team is now among the highest-volume users in the organization, reaching for Cassidy first across compliance questions, contract reviews, and everything in between.

Field reporting. The field services team commissions equipment and runs deployments globally, then documents the work at the end of long days on-site. With Cassidy, reports that previously took multiple days now take a matter of hours — with output that is more consistent and professional across the team. The group has also extended the platform to coupon analysis, a task they previously had no purpose-built tool for.

"It used to be that everyone was a little nervous about trying the tool. Now it's more like, 'Wait, I have another idea for Cassidy. Can it do this too?'"

— Sharon White, Operations, Cosasco

Driving Adoption Across a Global Team

Cosasco's operations team drove adoption by tying AI use to individual workflows and goals rather than issuing top-down mandates. Weekly usage reports tracked activity by team and individual, giving managers visibility into where adoption was strong and where more support was needed — and sparking friendly competition across groups in the process.

Multilingual support was one of the most significant drivers. Offices across the Middle East and India started communicating with Cassidy in their native languages and getting back answers in English, making technical documentation accessible to team members who had previously struggled to engage with it. Adoption spread quickly once the barrier was removed.

The Cassidy team stayed closely involved as the platform expanded — bringing new team members into direct conversations with specialists, refining workflows based on what was working, and consistently surfacing ideas from other deployments that Cosasco could apply to their own. Sharon describes it less as vendor support and more as a working partnership.

"I think that part has been super helpful — having your team grow along with us in our journey, brainstorming different ideas, and having different people in the organization talking to your team about how they're using it on the daily."

— Sharon White, Operations, Cosasco

The Impact

The 80% time reduction on applicable engineering tasks has held consistently since the first conformity assessment. When natural attrition created gaps on the team, Cosasco didn't need to rush to backfill. They found they could get more out of their existing staff, redirecting capacity toward higher-value work instead of scrambling to hire. More than 50% of the routine engineering questions that previously landed on senior engineers are now handled by Cassidy.

Quality has improved alongside speed. Output is professional, citation-ready, and consistent in a way that's hard to sustain through manual effort alone. Customers push back less. Internal reviews move faster.

"Across the board, the quality of the output — not only does it do it quickly, it's better. It's professional. It doesn't brook as much questioning. It's flawless every time."

— Eric Goodyear, Engineering Lead, Cosasco

What's Next

Cosasco's roadmap includes converting 20 years of data sheets and customer submissions into a structured, validated knowledge corpus, deeper integrations to handle complex relational product data, and extending AI-assisted reporting further across the field services team. By the engineering team's own measure, they're at "evolution B" — with several significant leaps still ahead, and a team now pushing hard to get there.
