Alert 99 – 33 More on Mismatched Hammer Unions
WHAT HAPPENED:
Representatives from operators, drilling contractors, service companies, suppliers, and manufacturers held an industry wide meeting in Houston in November 1999 to continue discussions on ways to eliminate and/or control the mismatched hammer union hazard (see IADC Safety Alert 98-01). A quick and universal engineering solution appears elusive.
