Drillstring Toolbox Premium vs Riser Safety Margin

The DS-1 team has created this Drillstring Toolbox Premium! It's an advance calculator that does everything the free Drillstring toolbox does and more! With it you can find: - API-recommended makeup torques for drill-stem connections with whatever sizes you want to plug in. - The "T4" (maximum tensile capacity) torque for those connections, too. - Adjusted makeup torques when you want to optimize away from the standard numbers. - Tensile and torsion capacities for standard, thick-walled, and custom drill pipe tubes. - A combined load curve for whatever combination you come up with, which you can email to your colleagues. - Recommended makeup torques for many popular proprietary connections.

This app is a tool for application on deepwater drilling operations (Oil & Gas). About Riser Safety Margin: The slight increase in mud weight needed to offset the loss in hydrostatic pressure when the riser is disconnected from the bop and the hydrostatic pressure of the mud to the mud line is replaced by the hydrostatic of the column of sea water. Emergency disconnection can occur in blackout condition, failure of the dynamic positioning system, etc. DISCLAIMER: These tools & materials are provided 'as is' without warranties of any kind, express or implied.
