BenthicLift

BenthicLift — Salvage Calculation Suite

BenthicLift is a professional-grade engineering calculator suite built for commercial divers, marine salvage teams, and underwater recovery operations. It delivers fast, on-device physics-based calculations designed for real-world field conditions where precision matters and mistakes are costly.

Working underwater requires more than estimates. BenthicLift replaces guesswork with reliable engineering models based on established physical principles.

Core Calculators

Lift Bag & Buoyancy Calculator (Archimedes’ Principle)
Calculate precise lift bag requirements for underwater recovery operations. Enter material type, object weight, and water conditions to determine submerged weight, displaced volume, and the number of 500 lb lift bags required.

Rigging Load & Sling Tension Calculator
Analyze multi-leg rigging setups before deployment. Input load weight, sling angles, and number of legs to calculate tension distribution and stress multipliers. Receive immediate warnings when sling angles drop below safe thresholds (below 45°).

Hydrodynamic Drag Estimator
Predict resistance forces during underwater ascent. Model object shapes including spheres, cubes, and flat plates under real current speeds in both freshwater and saltwater environments measured in knots.

Gas Expansion (Boyle’s Law) Calculator
Simulate gas expansion behavior in lift bags during ascent. Understand volume changes under pressure variations to prevent uncontrolled buoyancy and improve venting safety planning.

Built for Field Use
Fully offline functionality — no internet required
No accounts or subscriptions
Instant, on-device calculations
Designed for operational environments, not classroom theory

BenthicLift is engineered for professionals who need reliable answers in critical underwater conditions.
