摘要： A loading assembly has a gas conduit that extends between a floating structure and another structure, to convey a pressurized gas stream between the two structures. An emergency disconnection coupler is configured in the gas conduit. A switching system is provided for controlling switching of an engagement mechanism in the emergency disconnection coupler between a locked position and an unlocked position (in either direction). The switching system is subject to two distinct fail-safe regimes: a fail-unlocked regime which inherently instructs for release of the emergency disconnection coupler, and a fail-closed regime which inherently precludes release of the emergency disconnection coupler when there is pressurized gas in the gas connection. The fail-unlocked regime is active when the gas pressure in the gas connection is below a predetermined override threshold value. The fail-locked regime overrides the fail-unlocked regime.
摘要翻译： 装载组件具有在浮动结构和另一结构之间延伸的气体导管，以在两个结构之间输送加压气流。 在气体管道中配置了紧急断开连接器。 提供一种切换系统，用于控制紧急断开联接器中的接合机构在锁定位置和解锁位置（在任一方向上）的切换。 交换系统受到两个明显的故障安全方案的限制：一种故障解锁方式，其固有地指示释放紧急断开耦合器，以及一个故障关闭状态，当有压缩气体时，该故障关闭状态固有地排除了紧急断开耦合器的释放 气体连接。 当气体连接中的气体压力低于预定的超控阈值时，故障解锁状态是有效的。 失败锁定的制度超越了失败解锁的制度。
