Pressure Vessel Design & Detailing for a Refinery Revamp Project
Client Profile:
An international engineering consultancy involved in a refinery revamp project in the Middle East approached YSC India for end-to-end Pressure Vessel design and detailing.
Client Challenges:
Multiple Vessel Types
The client required the design of horizontal and vertical pressure vessels, each with different service conditions (high pressure, high temperature, corrosive fluids).
Tight Engineering Schedule
The project had to be executed within 4 weeks to align with the procurement and fabrication timeline.
Code Compliance Required
All vessels had to meet ASME Section VIII Div. 1 requirements with proper documentation and calculation reports.
Inconsistent Vendor Coordination
The client’s fabrication vendor had several changes in nozzle orientations and support types mid-design, which created delays in past projects.
YSC India’s Solution:
Expert Engineering Team
We assigned a senior mechanical engineer (ASME certified) and two draftsmen with prior refinery project experience.
Robust Design Calculations
Vessel sizing and thickness calculations were performed using PV Elite and cross-checked using in-house Excel tools for nozzle loads, MAWP, and MDMT.
3D Model & Fabrication Drawings
We provided detailed fabrication drawings, nozzle orientation plans, and 3D CAD models for better visualization and review.
Client-Vendor Coordination
YSC directly communicated with the fabrication vendor to adjust support locations and optimize lifting arrangements, reducing miscommunication.
Document Package
We delivered complete packages including GA Drawings, Detail Drawings, Design Calculations, Weld Maps, and Bill of Materials.
Results Delivered:
Code-Compliant Design
All vessels passed third-party design review and met ASME requirements without any comments.
Faster Execution
Design & drafting for 4 vessels were completed in 3.5 weeks, ahead of schedule.
Reduced Rework
Clear 3D visualization helped avoid fabrication errors and saved rework time at the shop.
Cost Optimization
With optimized plate thickness and nozzle configurations, the client saved on material and fabrication costs.
