Overview
Elixir Engineering provided Structural calculation consultancy services for Tyco Fire & Security’s nitrogen cylinder skid packages. These skid packages are critical components of fire suppression systems, ensuring the safe and reliable storage of nitrogen cylinders. Our consultancy services ensured that the design, stability, and safety of these skid packages met all required industry standards.
What Are Nitrogen Cylinder Skid Packages?
A Nitrogen cylinder skid package is a structure designed to house multiple nitrogen cylinders used in fire suppression systems. Nitrogen helps maintain pressure or displaces oxygen in fire protection setups, making it essential for ensuring effective fire control and suppression.
- Qatar Gas intends to develop production of North field and awarded the “NORTH FIELD PRODUCTION SUSTAINABILITY (NFPS) PROJECT INVESTMENT 1 PROJECT 1” EPC Contract to M/s McDermott.
- In project scope, installation of Nitrogen Cylinder Racks for WHP10N & WHP11N platform is included.
- M/s McDermott, invited the vendors and awarded the Sub-Contract for installation of Nitrogen Cylinder Racks for WHP10N & WHP11N platform to M/s Tyco Qatar Fire and Security.
- Structural design and stability analysis of the Nitrogen Cylinder Rack skid has been performed by Elixir Engineering for Tyco Qatar Fire and Security.
Execution Methodology:
- Review of P&ID and Preliminary GA drawing
- Review of Tie-in Schedule and Material Specifications
- Review of Piping material specification and Structural material specification
- Definition of weight for all parts inside the Nitrogen Cylinder racks.
- Definition of Support type and support details
- Cylinder loads and other components load values are provided to Structural team to check integrity of Structural arrangements.
- Modelling of Structural members as per provided GA drawing in Software.
- Definition of Piping loads (Axial, Vertical & Friction loads) in all support locations.
- Definition of other components load on the specified structural locations.
- Definition of External load conditions (Wind load, Seismic parameters) as per project design specification and API RP 2A Ed 22& API RP 2EQ, Ed 1.
- Definition of number of Anchor points and its location.
- Performing structural analysis and check the results for deflection, torsion and other induced stress values.
- Based on the results, additional recommendation to stabilize the structural arrangement for its design life performance. (i.e., Member modification, Wear plate and additional bracing, etc.)
- Performing the analysis for In place condition, lifting condition, Road Transportation condition and Sea/Barge Transportation condition as per acceleration values provided by Client or Project design specification.
- Preforming Lifting lug design and analysis
- Performing Anchor bolt design and analysis
- Performing analysis for Shackle and sling arrangements. Providing the recommendation for suitable lifting plan.
- Preparation of complete report with Results summary and Software results for Structural analysis of Nitrogen Cylinder racks.
- Submission of GA drawing based on the study recommendations.
Why Structural Calculations Are Critical
Structural calculations are essential for ensuring that nitrogen cylinder skid packages are designed for optimal safety and performance. Key areas of focus include:
- Weight Distribution: Calculating the combined weight of nitrogen cylinders and ensuring the skid can support it.
- Stability: Ensuring the structure is stable and secure during transport, installation, and use.
- Pressure Resistance: Evaluating the skid’s ability to withstand the internal pressure exerted by nitrogen.
Deliverables:
- Detailed Structural Design Calculation Report
- Skid GA drawing
