O&M BoP: Threats• External corrosion
• Below water (CP)
• Splash zone
• above water
• Internal corrosion
• Vibrations: macro (fatigue)
• Vibrations: micro (bouten e.d.)
• Scour protection
• appendages (cranes, nav lights,
.)
• Cable damage
• ...
17
O&M BoP: Open questions
• Scour protection: currently lack of knowledge/models• Vibrations: lack of knowledge/models; link to scour
protection?• Internal corrosion: bacteriel processes• CBM
