Summary
Investigation of a snubbing rig collapse during well servicing on an offshore platform. Waterspout winds and an incorrect guy-line angle were identified as likely causes. The report examines support geometry, wire-rope strength and deck constraints, and recommends proper angles and additional lines where space is limited. No injuries or pollution were reported.
