Pressure Vessel Design
Project Overview
Engineering Design Services provided industrial design engineering support for a large-scale fractionation facility in South Texas. The project involved the engineering and construction support of multiple light-end bullet tanks used for Liquefied Petroleum Gas (LPG) storage as part of a 100 million barrel per day fractionation operation. Each vessel exceeded 150 feet in length and 16 feet in diameter and required detailed mechanical and structural engineering to support safe long-term operation.
Result & Impact
• Delivered safe and reliable LPG storage infrastructure for a major fractionation facility
• Ensured full compliance with ASME codes, industry standards, and safety regulations
• Improved fabrication quality through proactive inspection and oversight
• Reduced potential rework and construction issues during fabrication
• Supported the long-term operational reliability and efficiency of the facility
Engineering Tools & Technologies
• Pressure vessel mechanical design
• Structural analysis and saddle support design
• ASME code compliance methodologies
• Fabrication inspection and quality assurance processes
• Industrial CAD and engineering modeling tools
• Dimensional verification and material inspection procedures
Scope
• Complete mechanical and structural engineering of LPG bullet tanks
• Design of vessel support saddles and associated structural components
• Code compliance verification for pressure vessel systems
• Fabrication oversight and construction quality assurance
• Weekly inspections at the fabrication facility
• Material verification and dimensional accuracy checks
• Review of fabrication against approved engineering drawings and specifications
Solution
Engineering Design Services delivered full pressure vessel engineering services for the LPG storage system, including vessel calculations, structural support design, and fabrication support. The team ensured all vessels met applicable ASME requirements, industry standards, and project safety criteria. In addition, EDS implemented an active quality assurance program through recurring fabrication shop inspections to verify construction quality, minimize rework, and maintain compliance throughout fabrication.
