I am finalising the design of an engine-room CO₂ fire-suppression package and need an expert who can run and document the NFPA 12 flow calculation with absolute accuracy. The calculation itself is the heart of the job; pipe sizing, nozzle selection, and overall layout validation will follow once the flow rate is confirmed. You will work with the exact volume data I supply for the engine room; if you like to factor in air-change rates or risk classifications, feel free to note those in your commentary, but the delivered numbers must be driven primarily by the protected volume so they line up with the Class rules and IMO circulars. Deliverables • A complete NFPA 12-compliant calculation report in a format acceptable to Class • Native output from any recognised software package (please state whether you use ANSTO, FIRECAD, FLACS, or another equivalent tool) • All supporting documents needed for design submission, including pipe and nozzle schedules where applicable To help me assess fit, include a short overview of your previous marine CO₂ projects, name the software you will use, and attach a sample report if possible. A concise commercial proposal with lead time is appreciated.

Hello, I can support you with accurate NFPA 12 CO₂ flow calculations for your engine-room fire suppression system and provide a complete, Class-ready calculation package. I’m a Mechanical Engineer with experience in piping systems, industrial layouts, and code-based design, and I understand the importance of precision when working with CO₂ systems, especially for marine applications aligned with IMO and Class requirements. I can also share samples of similar calculation and technical documentation work. Approach: • Perform NFPA 12-compliant CO₂ quantity and flow calculations based on the protected engine-room volume • Apply appropriate design concentration, discharge time, and safety factors per NFPA 12 and marine standards • Document any assumptions (air changes, leakage, hazard classification) clearly in the report • Validate results to align with IMO circulars and Class expectations Software: I typically use engineering calculation sheets (Excel-based with NFPA validation) and can format outputs to match recognised software-style reports. If required, I can adapt to FIRECAD/other tools depending on your preference. Deliverables: • Complete NFPA 12 calculation report suitable for Class submission • Structured calculation sheets with traceable methodology • Preliminary pipe and nozzle schedule based on calculated flow • Supporting documentation for design validation.
