Summary
An investigation into a telescopic joint dropping approximately 15 feet on a spar rig identifies failure of four running-tool j-pins. Investigators attributed the failure to loading beyond design limits, probably during crane handoff and righting. The report discusses missing manufacturer operating parameters and limitations of routine visual inspection; nobody was injured.
