BlueScope Steel Coke Plant No.6 Maintenance Project
Executing structural modifications within an active, high-temperature furnace environment demands absolute engineering precision to prevent catastrophic downtime. Collaborating closely with leading engineering consultancy L.E. Otten, KEVOS® delivered critical 2D CAD drafting, installation, and manufacturing drawings for the BlueScope Steel Coke Plant No.6 upgrade. By detailing every structural steel modification prior to shutdown, we ensured safe, accurate, and on-schedule execution by site contractors.
Executive Summary
project profile & parametersIndustrial furnace modifications require intricate structural planning to accommodate extreme thermal expansion, complex machinery routing, and limited contractor workspace. For the BlueScope Steel Coke Plant No.6 Maintenance Project, KEVOS® provided precise 2D CAD visualizations of the entire furnace modification zone. Working under the guidance of L.E. Otten, our team transformed conceptual upgrades into highly accurate manufacturing and installation drawings. This proactive drafting strategy allowed contractors to pre-fabricate materials off-site and assemble them flawlessly during critical shutdown windows, delivering the project on time and within budget while strictly managing on-site safety risks.
In heavy industrial maintenance, field modifications are prohibitively expensive and dangerous. Precise 2D CAD drafting resolves spatial clashes before fabrication begins, securing continuous plant operations.
- Generate comprehensive manufacturing drawings to enable off-site steel pre-fabrication.
- Produce clear, step-by-step installation guides to accelerate on-site contractor assembly.
- Identify and resolve spatial and structural interferences virtually prior to plant shutdown.

Key Takeaways
essential project lessons- Drafting minimizes downtime — resolving structural complexities in 2D CAD drastically reduces physical installation time.
- Pre-fabrication is crucial — detailed manufacturing drawings allow steel to be built off-site, avoiding hazardous in-situ welding.
- Visuals bridge communication gaps — clear installation blueprints ensure fabricators, engineers, and contractors execute flawlessly.
- Plan for the environment — designing for a coke plant means accounting for extreme temperatures and thermal material expansion.
- Detect clashes early — overlaying new designs onto legacy plant layouts prevents new steel from hitting existing pipes.
- Accurate procurement saves budgets — using CAD to generate precise material lists stops over-ordering and waste.
- Collaboration drives success — working closely with lead consultants like L.E. Otten ensures designs meet macro project goals.

Frequently Asked Questions
clarifying the design processWhy are installation and manufacturing drawings separated?
Manufacturing drawings focus on a single piece of steel, showing fabricators exactly where to cut and drill. Installation drawings show the big picture, guiding contractors on how to assemble those pieces together on-site.
How does CAD software improve safety during maintenance?
By identifying potential issues in the digital model, contractors avoid dangerous, ad-hoc problem-solving on the factory floor, significantly reducing their exposure to hazardous industrial environments.
What makes furnace modifications particularly challenging?
Furnaces operate at extreme temperatures, causing steel to expand and contract. The drafting must account for these thermal shifts, ensuring joints have enough tolerance to move without warping.
How did drafting help deliver the project on time?
By providing perfectly accurate manufacturing drawings, the steel could be fabricated off-site beforehand. This meant contractors only had to bolt things together during the shutdown, rather than building from scratch.
What was the role of L.E. Otten in this project?
L.E. Otten was the lead engineering consultancy. We collaborated with their team, transforming their overarching structural strategies into the practical, executable CAD drawings used by the builders.
Why is early problem identification so critical in plant maintenance?
Once a plant shuts down, every hour costs money. Finding a structural clash during the shutdown causes massive financial loss. Finding it in CAD costs almost nothing to fix.
