Summary
A near miss during bell and clump-weight deployment involved a protruding wire strand. Following recovery, inspection identified 60 m of damaged rope for removal and re-termination. Third-party load testing preceded resumed diving. Lessons address visual inspection, defect reporting and limiting rope stress from tidal currents and adverse weather.
