彻底减少警报

森科尔

Suncor是加拿大最大的综合能源公司之一，专门从事油砂的开采及其随后的升级和提炼成高质量的石油产品。 Suncor 总部位于阿尔伯塔省卡尔加里，通过其 1,500 多个加拿大石油加油站网络向工业和商业客户以及零售客户销售成品。 Suncor 的 Fort Hills 矿山是一个露天卡车和铲式矿山，于 2018 年投产，每小时可开采 154,000 吨油砂，每天生产 194,000 桶沥青。

虽然警报旨在为控制室操作员提供异常情况的预警，但许多新的工业场所面临警报系统“过度活跃”性能的挑战。在 2018 年完成 Fort Hills 站点的调试后，Suncor 的控制室操作员面临的平均警报负载比警报管理标准和最佳实践建议的高出 30 倍。

这些警报负载，再加上工厂故障导致的频繁警报泛滥，导致操作员严重超负荷，从而增加了现场发生安全、环境和生产相关事故的风险。

为了实现警报系统性能的逐步改变，Suncor 启动了警报系统改进计划，选择遵循符合标准的流程，特别是 ANSI/ISA-18.2-2016，过程工业警报系统管理。

此过程的第一阶段是制定警报理念，记录 Fort Hills 现场警报管理的预期方法，以便警报系统改进计划的后续阶段以受控和一致的方式执行。

• The alarm system improvement initiative led to a significant reduction in alarm load. Within a month, the average alarms per operator (per 10 minutes) reduced from 30 to 12 (60%). This trend continued to only six (an 80% reduction) in the following month. Over a period of two years, the team has successfully achieved and sustained a 95% reduction in alarm load that is in-line with ISA 18.2 standards. The improvements achieved were significant, with alarm annunciations dropping from nearly 270,000 in May 2018 to 12,000 in April 2020. The top 5 bad actors contributing to the alarm system load also reduced from 40% to 15%. The use of Honeywell Forge Alarm Management was central to these improvements, helping to direct the team’s efforts to improve and sustain alarm system performance, reducing safety, environmental and production related risks while also increasing uptime.

• 95% sustained reduction in alarm load
• 80% reduction in alarm load within months
• From 270k to 12k alarms per month
