Influence of temperature and crossing angle on the tribo-corrosion-fatigue behaviors of steel wire ropes of winch drum in offshore drilling rig

Key Points

• Tribocorrosion exhibits a direct relationship with temperature and crossing angle.
• The maximum fatigue life occurs at optimal angles, specifically between 30° and 45° during tests.
• Assessment using tribological stress indicators reveals significant interaction effects between variables.
• Findings suggest that understanding tribo-corrosion may enhance maintenance strategies for offshore equipment.
