Dominion Energy：在 Surry 核电站大修期间对凝汽器进行无人机检查
Dominion Energy 的内部团队用无人机检查 Surry 核电站的冷凝器。据称省去全套脚手架后，检查从一周以上缩短到两个12小时班次，每次停机节省超过200,000美元。文章内部的节省数字前后不一致，且维修处仍需脚手架。
| 业主 | Dominion Energy |
| 服务商 | — |
| 地点 | Surry County, Virginia, United States |
| 机型 | Flyability Elios 3 (with UT payload) |
| 传感器 | 4K camera, ultrasonic thickness (UT), LiDAR |
引入前
在冷凝器内部及周围搭设脚手架并进入受限空间：搭设需 12–14 个十二小时班次，拆除需 4–6 个班次，每班至少六名脚手架工，每小时费用超过 1,000 美元。
引入无人机后
Dominion 的内部无人系统团队操作无人机采集视频、UT 和 LiDAR 数据；仅在需要维修的位置搭设脚手架。
成果
| 指标 | 数值 | 依据 |
|---|---|---|
| inspection duration | from over a week to two 12-hour shifts (headline: 8 days to 8 hours) | 报告值 |
| cost per outage | over US$200,000 saved (headline says US$150,000) | 报告值 |
| labour | 12–14 scaffolders released for other work | 报告值 |
注意事项与局限
- Manufacturer case study; savings figures are inconsistent between headline and body.
- Inspection year not stated.
- Scaffolding is still needed for repair locations; the drone replaces only the survey step.
- The '$3 million per day' outage figure on the page is a general industry number, not Surry-specific.
