Petrol engine and tank compartment ventilation requirements
Launch CalculatorThe ISO 11105:2020 ventilation calculator determines the minimum ventilation requirements for compartments containing petrol engines and/or petrol tanks on small craft. This comprehensive tool calculates both natural and powered ventilation requirements based on compartment volume and equipment specifications.
Calculate ventilation for engine compartments, tank compartments, or combined compartments with automatic formula selection.
Determine requirements for both natural ventilation openings and powered ventilation systems per ISO 11105 standards.
Automatically calculate minimum duct cross-sectional areas for inlet and outlet ventilation systems.
Instant pass/fail indicators showing whether your ventilation design meets ISO 11105:2020 requirements.
This calculator is provided as a design aid for ventilation systems. All ventilation installations must be inspected and verified by qualified marine surveyors. Proper installation and testing are critical for safety and certification compliance.
ISO 11105:2020 specifies requirements for the design and installation of ventilation systems for compartments containing petrol engines and/or petrol tanks on small craft. Proper ventilation is essential to prevent the accumulation of explosive fuel vapors.
Design compliant ventilation systems during vessel construction. Ensure all petrol-related compartments meet safety standards.
Calculate ventilation requirements for engine installations and fuel system designs. Verify compliance before commissioning.
Verify ventilation compliance during surveys and inspections. Generate documentation for certification purposes.
Integrate proper ventilation requirements into vessel design specifications and general arrangements.
While this calculator helps with design calculations, ventilation systems require professional inspection and certification.
