Ton Miles Calculator vs Drillstring Toolbox

The Ton Miles Calculator is an essential, precision mobile tool designed specifically to manage and maximize the service life of wire rope used in rig suspension systems (drilling lines) during well-drilling operations. This application provides the useful tools for use of Wire Rope (Drilling Line) for Oil Field Service and in the drilling engineering schools. API Recommended Practice 9B: Developed strictly in accordance with API RP 9B standards, incorporating official engineering formulas for accurate ton-mile evaluation. Key Capabilities: - Complete Operational Coverage: Calculate ton-miles for Tripping, Drilling, Coring, Setting Casing, Setting Liner, and Running Riser. - Integrated API RP 9B Formulas: Built-in visual formula reference for full transparency on calculations. - Ton Miles Control Log: Track cumulative ton-miles to slip & cut-off thresholds in real time. - Industry Co-Development: Created in partnership with top field experts for professionals, engineers, students, and academics. - Native iOS & iPadOS: Built optimized for iPhone & iPad with iCloud Drive file syncing support. Calculations and formulas for: - Round Trip - Halt Trip - Short Trip - Drilling (options for kelly or top drive, with reaming or not) - Coring - Setting Casing (also with landing String on subsea operations) - Setting Liner - Running Riser (on subsea operations) Save calculations with historical of the all parameters per register. Please, visit the support url to download the "User Guide". Our Mission Developed alongside industry experts using established spreadsheets, this app provides an accessible, cost-effective tool for drilling engineers, toolpushers, drillers, technicians, students, and instructors. It is designed as a practical field utility and learning companion, not a replacement for full-scale commercial engineering software. Feedback & Community We continuously improve our tools.

Drillstring Toolbox is a free calculator from Standard DS-1 that gives you the drill-stem load capacities you need! You can choose an API connection (along with the size you're interested in) to find its recommended makeup torque and tensile capacity. Tap the "Tube" tab to find the tensile and torsion capacities for drill pipe tubes as well!
