Drill Pipe Alloy

• Torque and drag reduced • Pull out loads reduced • Topside equipment and power

requirements reduced • Radical extensions in reach

(possibly double or more)• Reduce the number of platforms

or subsea completions for field development

• Robust, damage-tolerant, longer-life string

Notes:aThe static vessel offset plus or minus the low frequency offset caused by wind and wave-drift forces should be included in the riser analysis.bMay use less than 100-year event if risk consistent criteria are maintained.cAssoicated wind, current profile or wave to be determined by considering joint wind, wave and current probabilities.dWave and current conditions should be based on the season during which the operation will take place, the duration of the operation and weather forecasting accuracy.eWSD = wave scatter diagram.
