The Challenge
The long term integrity management of offshore buoy moorings chain connectors is mandatory, especially for preventing any risk of fatigue corrosion cracks.
The chain connector is basically a few meters long hawse pipe fully immersed in seawater with the ratchet on buoy side and the guide ring on the other side.
A few links of chain located inside this pipe must be efficiently cathodically protected from sacrificial anodes which can only be located on the external part of the hawse.
