Summary
MAIB’s second bulletin on Zarga’s mooring-rope failure examines jacketed HMPE construction, hidden yarn damage consistent with axial compression fatigue, and undersized fitting rollers. Following serious injury to a deck officer, it strongly advises operators to consult manufacturers about rope suitability, fitting compatibility and condition monitoring before ropes become materially degraded.
