Restoring Coke Drum Integrity in Logistically Challenging Environments
Structural Reinforcement Under Geographic and Regulatory Constraints At a remote South American refinery, inspection identified severe shell bulging and weld seam cracking across multiple coke drums. The structural concerns were significant, but the operating environment added a second layer of complexity. Limited infrastructure, extended supply chains, and local regulatory requirements elevated execution risk beyond typical […]
150+ Keyhole Repairs Under Live Discovery Conditions
Managing Expanding Coke Drum Scope Without Schedule Loss During a Northern European refinery turnaround, routine inspection of two coke drums escalated into a high-volume defect remediation program. More than 150 keyholes were identified, with additional cracking revealed as repairs progressed. This scope became a live discovery environment requiring real-time engineering decisions, controlled execution, and disciplined […]
Coke Drum Cone Replacement During Refinery Turnaround
Global Mobilisation Under Extreme Turnaround Pressure A leading Western European refinery scheduled simultaneous cone replacement on four coke drums within a single turnaround window. Mid-project, newly fabricated cones were found to be slightly out of specification, causing a complication. In heavy-wall coke drum geometry, “slightly” can translate into distortion, misalignment, or cumulative delay across parallel […]
Engineering Coke Drum Structural Stability
360° Skirt Replacement Under Sustained Load When full circumferential cracking develops at a coke drum skirt-to-shell junction, the issue is no longer localized fatigue repair, but a structural stability challenge. A major Central European refinery identified advanced cracking and skirt dislocation on two coke drums. Inspection confirmed that less than 50% of the original support […]
Delivering Structural Coke Drum Repairs in 14 Days
Global Mobilisation Under Extreme Turnaround Pressure When one of the world’s largest integrated refining and petrochemical complexes identified deep OD/ID cracking across multiple coke drums, immediate action was required. Cracks extended to depths of 25–30 mm along the can sections, reaching up to 10 linear meters. The scope included structural weld overlay using Inconel 625 […]
How fired heater performance affects refinery margins in India
By Sean Matthew, Business Development Manager, India As one of the world’s largest refinery hubs, India’s refinery system operates in a performance environment where marginal inefficiencies can quickly escalate into commercial losses. According to the Energy Institute Statistical Review of World Energy 2025, Asia Pacific accounts for over 36% of global refining capacity, while India […]
