Bow-ties are used in multiple industries to effectively manage safeguards during operation. Benefits of bow-ties include clear communication, operator ownership, relationship between safeguards for various threats and consequences, and the visibility of safeguard health during operations. In oil and gas, the main application of bow-ties has been to manage high consequence risks pertaining to process safety, i.e. loss of primary containment of hazardous substances. Offshore structural and marine failures are not always driven by loss of primary containment, and as a result the use of bow-ties in offshore structures and marine is less established. This paper expands the application of process safety bow-ties into failure risks for structural and marine offshore facilities. First it’s introduced as a general framework, then implemented to select high-consequence offshore facility scenarios. Though less conventional than common approaches for designing against structural and marine failure scenarios, use of bow-ties is distinguished in its ability to manage risks which are mitigated by operational safeguards, such as ice feature overloads, offshore collisions, multi-line mooring failures, and loss of floating stability.

领结用于多个行业，以有效管理运营期间的安全措施。领结的好处包括清晰的沟通、运营商所有权、各种威胁和后果的保障措施之间的关系，以及运营期间保障健康的可见性。在石油和天然气领域，领结的主要应用是管理与过程安全有关的高后果风险，即有害物质的主要容器损失。海上结构和海洋故障并不总是由失去主要安全壳引起，因此在近海结构和海洋不太成熟。本文将过程安全蝴蝶结的应用扩展到结构和海洋海上设施的故障风险中。首先它作为一个通用框架引入，然后实施以选择高后果的海上设施方案。虽然在针对结构和海上故障场景进行设计的常规方法不如常规方法，但使用领结的特点在于其管理风险的能力可通过操作保障措施减轻，例如冰特征过载、近海碰撞、多线系泊故障、和失去浮动稳定性。
