纳伯斯公司质量、健康、安全与环境（QHSE）系统与分析经理克里斯·赖特表示，总可记录事故率（TRIR）是衡量钻井平台安全性的行业标准指标，但它并不能全面反映安全状况。TRIR 将所有事故一视同仁，无论其严重程度或影响如何，都可能掩盖关键风险，并限制管理层做出明智决策的能力。在2月18日于休斯顿举行的2026年国际钻井承包商协会（IADC）健康、安全、环境与培训（HSET）大会上，赖特先生介绍了事故严重程度率（ISR），这是纳伯斯公司正在使用的一种指标，它根据不同类型的事故赋予相应的权重。他表示，这能让公司更清晰地了解组织的安全状况。在本次视频采访中，赖特先生详细阐述了 ISR 的运作方式以及纳伯斯公司通过衡量 ISR 所获得的洞见。

Total recordable incident rate (TRIR) is the industry standard metric for measuring safety on the rig, but it provides an incomplete view of safety, said Chris Wright, QHSE Systems and Analytics Manager at Nabors. By treating all incidents equally, regardless of severity or impact, TRIR can mask critical risk exposure and limit leadership’s ability to make informed decisions. At the 2026 IADC Health, Safety, Environment & Training (HSET) Conference in Houston on 18 February, Mr Wright introduced the incident severity rate (ISR), a metric Nabors is using that assigns proportional weight to different types of incidents. This gives companies a clearer picture of organizational safety health, he said. Speaking to DC in this video interview, Mr Wright details how the ISR works and the insights Nabors has seen from measuring ISR.
