Configure each lift bag for the salvage operation. The system automatically calculates available buoyancy using Archimedes' principle with local seawater density, and predicts gas expansion during ascent using Boyle's Law. CRITICAL: Any bag marked 'EXPLOSIVE RUPTURE RISK' must be reconfigured before operation proceeds. Total buoyancy must exceed object dry mass by minimum safety factor of 1.5x.

Compressed Air
Nitrogen (N₂)
Helium (He)
Trimix (He/N₂/O₂)
Argon (Ar)

Do you confirm that all bags showing 'EXPLOSIVE RUPTURE RISK' will be reconfigured (reduce fill % or increase capacity) before operations?
CRITICAL SAFETY VIOLATION: Operation is NOT AUTHORIZED to proceed with any bag configuration that exceeds safe expansion limits. Revise lift plan immediately.
Total Calculated Buoyancy from All Bags (kg)
Safety Factor (Total Buoyancy/Object Dry Mass)
Is the safety factor greater than 1.5x?
INSUFFICIENT BUOYANCY: Add more lift bags or increase capacities to achieve minimum 1.5x safety factor.
Boyle's Law states that gas volume is inversely proportional to pressure. At 85 meters depth, absolute pressure is approximately 9.5 atmospheres (1 atm surface +8.5 atm hydrostatic). A lift bag filled to 1000 liters at this depth will expand to 9,500 liters at surface if venting fails.
Operational Depth for Expansion Calculation (meters)
Calculated Pressure at Depth (atm)
Expansion Factor (Pressure at Depth/Surface Pressure)
CRITICAL SAFETY THRESHOLD: Maximum safe fill percentage at depth = 100% / Expansion Factor. For 85m depth, maximum safe fill = 10.5% of bag capacity. Exceeding this creates explosive rupture risk during uncontrolled ascent.
Have all lift bag fill percentages been verified to be below the critical rupture threshold?
Provide engineering justification and alternative risk mitigation for any bag exceeding safe fill threshold:
I understand that failure to properly vent lift bags during ascent will result in explosive rupture, causing uncontrolled acceleration, equipment loss, and potential diver fatality.
