At Ras Al Khair, on Saudi Arabia’s eastern coast, the desert air is still cool at dawn. But inside Ma’aden Aluminum’s Calcination Plant, things are already heating up – literally. The plant is a critical link in the Kingdom’s integrated aluminum value chain, converting green petroleum coke into calcined petroleum coke (CPC), the feedstock for smelting anodes.
When the plant’s refractory linings in critical components reached their maintenance window, KAEFER Saudi Arabia was tasked with a 30-day shutdown. The scope: casting and gunning refractory materials in burners, cooling cyclones, and ducts – vital areas exposed to the plant’s extreme temperatures. The scale: a 220-strong workforce working day and night. The challenge: deliver under pressure. The result: completed in 28 days with zero incidents.
Here’s how it unfolded…
06:00 – Toolbox Talks and safety discipline
Each morning began with a ritual that set the tone: toolbox talks. With refractory works, dry-out, confined spaces, and hot work running in parallel, vigilance was the currency of safety.
“With 220 people on-site and high-risk activities, every detail mattered,” recalls HSE Officer Arunjith. “We carried out risk assessments, job safety analyses, and daily walkthroughs. Fatigue management across shifts was just as important as PPE and permits. The payoff: zero incidents.”
10:00 – Planning meets execution
By mid-morning, the focus shifted from talks to tasks. Behind every refractory installation was a detailed plan. Components like burners and cyclones are exposed to temperatures over 1,200°C and need precisely cast or gunned refractory linings to remain safe and efficient. Each step had to be carefully sequenced to avoid delays.
“Even a small delay could ripple through the entire shutdown,” explains KAEFER Planner Afsal. “Daily progress reviews, structured handovers, and milestone tracking kept us aligned. When refractory installation and dry-out phases finished ahead of plan, I knew we weren’t just on time – we were ahead.”
14:00 – Heat and hands at work
Afternoons belonged to the crews on the ground. For them, the shutdown was both a technical challenge and a physical test.
“The pressure peaked when multiple work fronts were live,” says Supervisor Shahid. “But the crew stayed calm, supported each other, and pushed through milestones early.”
Dry-out specialist Saini adds: “Dry-out is precise – too fast and the lining cracks, too slow and you lose hours. We rotated tasks, used the right tools, and looked out for each other. That’s how we managed both the heat and the hours safely.”
02:00 – Solving problems in the dark
Shutdowns don’t pause when the sun sets. For the night shift, focus and resilience mattered most. One lining issue threatened to derail progress, but teamwork carried the moment.
“At 2 a.m., the crew gathered, decided, and fixed it within an hour,” recalls Shahid. “Moments like that showed how committed everyone was to finish strong.”
Day 28 – Two days to spare
By day 28, the shutdown was complete. Refractory works and dry-out services were finished, the calciner was ready for service, and the project wrapped two days ahead of schedule.
“The uniqueness of this shutdown was its scale, complexity, and time pressure,” reflects Project Lead Premjith. “What stood out was the collaboration – operations, procurement, HR, safety, and site crews all aligned quickly. Supervisors and workers went beyond normal hours. The result was timely completion, zero incidents, and client appreciation.”
Beyond the shutdown
For Ma’aden, the project secured uninterrupted CPC production at Ras Al Khair, home to one of the world’s few fully integrated aluminum complexes. For KAEFER, it reinforced our position as a trusted partner in the Kingdom’s industrial growth, fully aligned with Vision 2030.
By the numbers:
- Scope: Refractory works & dry-out services
- Workforce: 220 skilled personnel (day & night shifts)
- Schedule: 30 days contractual → finished in 28
- Safety: Zero incidents
From toolbox talks at sunrise to quick problem-solving at 2 a.m., the shutdown wasn’t just about refractory linings or dry-out cycles. It was about people working under pressure – and proving that when collaboration and discipline meet, 30 days can become 28.
Or in the words of Premjith: “Challenging. Collaborative. Rewarding.”
