Systems-Theoretic Process Analysis results for system with different integration types

Published: 17 January 2021| Version 1 | DOI: 10.17632/prwtzmt3kg.1


The dataset consists of the results of Systems-Theoretic Process Analysis (STPA) for systems with different integration types. The investigated system is a subsea dry gas compression system, having both a process control system and safety instrumented system to ensure functional safety. The process & instrumentation diagram of the system is derived from the standard API RP 17V. To test the novel technology concept, which is the integration between process control and safety system, we provide modification in the architecture of the system and perform a hazard analysis to identify the implications. The four architecture types in the dataset are complete independence, conditional independence, partial integration, complete integration. A reference linked to a published paper by the same authors is provided to better understand the investigated system and the methodology used to obtain the dataset.


Steps to reproduce

We derived the study case based on the novel technology concept proposed by the project partner and integrate the concept with a generic subsea processing system found in standard API RP 17V. The analysis procedure follows the STPA Handbook (2018) by Nancy Leveson and John Thomas. The access database files are obtained by developing a template to record the STPA analysis results.
