02 · CHALLENGES
Business Challenges
Lightning-Prone Sea Areas, Lightning Event Frequent
Offshore Wind Farm Tower Height Can Over 100 Meters Up, in Lightning-Prone Sea Areas, Annual Lightning Strike Days Significantly Higher than Onshore, Tower & Blade Frequent Withstand Direct Lightning & Induced Lightning Strike.
Offshore Inspection Cost High, Window Short
Offshore Wind Farm Tower Inspection Requires Boat Trip, Affected by Sea Conditions, Weather, Tides Affect Significantly, Inspection Window Short, Single-Trip Cost High, Hard to Achieve High-Frequency Full-Cover Inspection.
SPD Degradation & Grounding Resistance Change Hard to Sense
Tower Top SPD Long-Term Lightning Strike Shock Exists Degradation Risk, Marine Salt Spray Environment Accelerates Grounding Grid Corrosion Causes Grounding Resistance Change, Lack Online Monitoring Means Cannot Early Warning.
Lightning Strike Fault Locate & Classification Lack Data
Lightning Causes Unit Fault Downtime After, O&M Team Hard to & Time Locate Lightning-Struck Units & Assessment Lightning Level, Affect Fault Handling Efficiency & Insurance Claim Evidence.
