Project Scope
The project scope comprises Detail engineering of Piping, comprehensive 3D modelling, and Piping stress analysis, Civil and Structural engineering for the Wet SRU, Ammonia, and Dry Seal flare gas, Flare Systems including KO Drums, Flare Risers, Molecular Seals, Flare Tips, and flare headers up to 48 inches.
Development and finalization of engineering deliverables for procurement, fabrication, construction, and commissioning activities.
The flare system in the project comprises following systems:
• Flare System for Wet SRU.
• Flare System for Ammonia.
• Flare System for Dry Seal flare gas.
Each system is engineered with dedicated or common headers, ensuring safe segregation, controlled disposal of hydrocarbons, and efficient handling of varying pressure and composition streams.
At the core of the project lies Piping engineering and highly detailed 3D model, that serves as a single source of truth for all engineering disciplines.
The piping scope includes design of large-bore flare headers (up to 48 inches) from battery limits to KO drums and onward to flare stacks, ensuring proper slope for drainage, minimal pressure drop, and accessibility for operation and maintenance and Integration with civil, structural, E&I systems using 3D modelling for efficient coordination.
Engineering activities include piping routing, piping layout development, critical line stress analysis, utility integration and multidisciplinary coordination.
Given the extreme conditions in flare systems, detailed stress analysis is a critical component to take care of Thermal Expansion, various load considerations like Sustained, occasional and dynamic loads with support optimization and code compliance.
The project includes a common derrick structure supporting multiple flare systems, designed for both functionality and safety to withstand environmental loads such as wind and seismic forces also trussell support and Piperack are designed to support large diameters flare headers.
Access Platforms, Stairs & Ladders are designed for safe operation, access for inspection and maintenance at elevated heights.
