Localized Corrosion of Mooring Chain Steel in Seawater [PDF]

Corrosion and Materials Degradation, 2022
Corrosion of mooring chains is regarded as one of main threats to the offshore mooring systems. Localized corrosion is even more dangerous than uniform corrosion because it may not show significant mass loss but it can cause stress concentration and ...

Fatigue analysis on the mooring chain of a spread moored FPSO considering the OPB and IPB

International Journal of Naval Architecture and Ocean Engineering, 2019
The appropriate design of a mooring system to maintain the position of an offshore structure in deep sea under various environmental loads is important. Fatigue design of the mooring line considering OPB/IPB(out-of-plane bending/in-plane bending) became ...

Study on characteristics of mooring system of a new floating offshore wind turbine in shallow water by experiment

Frontiers in Energy Research, 2023
At present, researches on floating offshore wind turbine are mainly focused on deep water areas beyond 50 m, and less research has been conducted for shallow water. Considering that the floating fan still has many application values in 30 m–50 m area, it

Modification of Surface Buoy to Preserve Under Water Habitat in Raja Ampat

Kapal, 2022
The ecosystem of the seabed is threatened by anchoring operations. Modifications were required to reduce the damage to seabed biodiversity. A laid chain on a mooring system is one of the causes of damage to the seabed environment.
