COMMERCIAL DIVING GAS CONSUMPTION CALCULATOR
Professional gas management tools for offshore and saturation diving operations
Commercial Diving Gas Management
Essential calculations for safe gas planning in commercial and saturation diving operations:
✓ Gas Consumption = SAC Rate × Absolute Pressure
✓ Absolute Pressure = (Depth ÷ 10) + 1 bar
✓ Dive Duration = Available Gas ÷ Consumption Rate
Working Gas Calculator
Calculate gas consumption for normal commercial diving operations
Gas Consumption at Depth
Consumption = SAC Rate × Absolute Pressure
Absolute Pressure = (Depth ÷ 10) + 1
Absolute Pressure = (Depth ÷ 10) + 1
Enter values and click calculate
Imperial Gas Consumption
Consumption = SAC Rate × Absolute Pressure
Absolute Pressure = (Depth ÷ 33) + 1
Absolute Pressure = (Depth ÷ 33) + 1
Enter values and click calculate
Bailout Gas Calculator
Emergency gas planning for commercial diving bailout scenarios
Bailout Gas Planning
Available Gas = (Tank Pressure - Absolute Pressure - Reg Pressure) × Tank Volume
Duration = Available Gas ÷ (Bailout SAC × Absolute Pressure)
Duration = Available Gas ÷ (Bailout SAC × Absolute Pressure)
