Summary
An investigation examines a completion-basket lift from Toby Tide at Heritage Platform. A single stinger and hook produced shallow sling angles, allowing slings to disengage and 58 of 73 pipe subs to spill into the ocean. Findings identify unrecognised rigging errors and expired rigger certification, and recommend proper rigging procedures.
