Abstract

Subsea shell deployment is a challenging operation due to the harsh marine environment, complex procedures, and potential for human error. This study presents a dynamic safety assessment of the pendulous installation of subsea shells using STAMP and DOOBN. Considering the complexity and multitude of influencing factors in subsea shell operations, STAMP is applied to identify risk factors across four critical stages, i.e., marine transportation, lifting into water, pendulum motion, and seating installation. The causal logic and interactions among these risk factors are analyzed to develop stage-specific DBN models, which are integrated into a DOOBN model for risk assessment of the entire deployment operation. This model enables the evaluation of reliability at each stage, and dynamic failure probabilities can be calculated. The critical influencing factors can be identified, and the risk mitigation strategies can be developed base on the outcomes of the model. A case study is used to illustrate the model, which is useful for enhancing the safety of subsea shell deployment operations.

基于STAMP和DOOBN方法的海底壳体展开作业动态安全评价

由于恶劣的海洋环境、复杂的程序以及人为错误的可能性，海底壳作业是一项具有挑战性的作业。本研究采用STAMP和DOOBN对海底壳体悬垂装置进行了动态安全评估。考虑到海底壳作业的复杂性和众多影响因素，STAMP应用于识别四个关键阶段的风险因素，即海上运输、升入水中、摆锤运动和阀座安装。分析这些风险因素之间的因果逻辑和相互作用，以开发特定于阶段的DBN模型，这些模型被集成到DOOBN模型中，用于对整个部署操作进行风险评估。该模型能够对各阶段的可靠性进行评估，并计算出动态失效概率。可以确定关键的影响因素，并根据模型的结果制定风险缓解战略。通过实例分析说明了该模型的有效性，该模型有助于提高海底部署作业的安全性。

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
