Split Pins - Applications and Alternatives

Lukasz Szadkowski NOV

A brief overview of dropped object statistics within NOV since 2012. The trend is steeply upward with the number of reported incidents almost doubled.  Some discussion around this trend considered better reporting as a major contributor but greater analysis and investigation is clearly required. The main focus of Lukasz’s presentation was on applications and alternatives for split pins. Various examples were shown and discussed. NOV are working on potential redesigns and offered their latest “cotter ring” concept for consideration. NOV demonstrated the design, safety, and ease of retrofit. Ball lock pins were also reviewed and discussed. Issues around durability, contamination and integrity were dominant.  NOV welcome further feedback (to Lukasz.Szadkowski@nov.com).
