01 · BACKGROUND
Customer Background
Enterprise Type
A large petrochemical enterprise affiliated with the national energy and chemical system, specializing in crude oil storage and transportation, petrochemical product production, and fine chemicals. As a national critical infrastructure operator, it strictly entoces safety red lines and compliance audits, with lightning protection safety being a core part of its production safety system.
Enterprise Scale: Large State-owned Enterprise [TBD] · Operating Annuals: [TBD]
Tank Farm Scale
Owns multiple large tank farm groups with large area and high storage capacity, wide and complex grounding grid distriBution. Constrained by tank farm explosion-proof area classification and operational safety, traditional manual inspection Cannot achieve high-frequency full coverage, with long-term monitoring blind spots.
Tank Farm Count/Total Capacity: [TBD] · Grounding Point Count: [TBD]
Industry Position
Key industry regulatory unit, classified as high lightning protection risk. Must strictly comply with mandatory standards including GB 50057 Building Lightning Protection Design Code, GB/T 21413 Petroleum Reserve Lightning Protection Technical Specifications, and GB 50160 Petrochemical Enterprise Design Fire Protection Standard, accepting joint supervision from emergency management and meteorological authorities.
Compliance Standard: GB 50057 / GB/T 21413 / GB 50160
02 · CHALLENGES
Business Challenges
Low Manual Inspection Efficiency, Large Blind Spots
Tank farm grounding points are numerous and widely distriButed. Traditional hand-cranked grounding resistance meters require manual point-by-point measurement, with long cycles and incomplete coverage, making it difficult to detect grounding degradation hazards in time.
Lack of Data Support to Lightning Risk Assessment
Tank farms are high lightning risk areas, But lack long-term continuous grounding resistance and lightning current monitoring Data, unable to support lightning risk assessment and lightning protection engineering decisions.
SPD Degradation Cannot Be Perceived in Real-time
Surge protective devices (SPDs) withstand lightning strikes and switching overvoltages over time, with degradation and failure risks. Traditional SPDs lack online monitoring capability, unable to provide timely warning after failure.
Compliance Audit Evidence Collection Difficulties
Petrochemical industry lightning protection compliance audits require complete, continuous, traceable monitoring Data. Paper records and discrete Data Cannot meet regulatory and audit evidence requirements.
