2026年4月16日，CIMAC、One Sea、航海学会和INTERCARGO联合呼吁国际船级社协会（IACS），要求针对驾驶台与机舱控制室（ECR）之间的推进动力控制（RPM）切换规则发布统一解释。各组织警告称，不同船级社甚至不同项目之间的差异化解读导致了控制层级不一致，给操作人员和船员带来了安全风险。国际公约（如SOLAS）未明确定义推进控制切换的层级，留下了自由发挥的空间。
许多船东（尤其是邮轮领域）通常采用既定模型：操舵权留在驾驶台，而推进动力遵循既定程序。在停电恢复期间，临时由机舱控制是公认的安全做法，有助于在控制权返回驾驶台前快速稳定系统。联署组织认为，除非有明确的安全理由，否则不应偏离既定程序。不一致的系统会增加船员工作量并降低态势感知能力。各方邀请IACS提供协调一致的指南，以确保行业安全标准的统一实施。

CIMAC, One Sea, the Nautical Institute and INTERCARGO have jointly called on the International Association of Classification Societies (IACS) to issue a unified interpretation of class rules governing the changeover of propulsion power control (RPM) between the bridge and the engine control room (ECR).The organizations warn that differing interpretations across classification societies and even between individual projects are leading to inconsistent control hierarchies, creating safety risks for operators and crews. They note that international regulations such as SOLAS do not explicitly define a propulsion control changeover hierarchy, leaving room for divergent approaches.Many shipowners, particularly in the cruise sector, operate under a proven model in which steering authority remains on the bridge, while propulsion power follows established operational procedures. Temporary ECR control during blackout recovery is a well established safety practice, enabling faster stabilization of electrical systems before control is returned to the bridge.According to the co-signatories, deviations from established operating procedures should only be introduced where supported by a clear safety rationale and evidence of risk reduction. They caution that inconsistent systems across sister ships can increase crew workload, reduce situational awareness and raise the likelihood of human error.The organizations invite IACS to provide harmonized guidance to ensure consistent, safety based implementation across the industry and offer their expertise to support further technical dialogue.
