Summary
Challenges in Plant Commissioning
The commissioning and startup of a large process plant can be chaotic, with numerous contractors and management working under pressure to ensure timely completion. Control valves are critical components often subjected to misplacement, damage, or improper installation during this hectic phase, leading to costly delays and unexpected expenses.
Importance of Vendor Engagement
A proactive approach with control valve vendors can greatly reduce risks associated with commissioning and startup. These vendors provide essential support during the procurement and installation phases, which helps ensure timely completion while maintaining OEM standards and warranty integrity. Engaging these experts early in the process leads to better coordination and clear communication among all parties.
Integrating Temporary Startup Trim Sets
To mitigate risks associated with expensive control valves during startups, the use of temporary startup trims is highly recommended. These trims aid in flushing and testing, preventing damage from debris and erratic behavior during startup. Once initial processes are complete, they can easily be replaced with operational trims.
Case Studies Highlighting Best Practices
Two notable case studies illustrate the importance of vendor engagement and correct installation practices. In a greenfield chemical plant and a combined cycle power plant, issues stemming from improper storage and installation led to costly repairs. Engaging the control valve vendor early allowed for prompt repair and resolution, demonstrating the value of expert involvement in startups.
