In this research, two methods, the STPA and Bowtie, were applied to realize a hazard identification on pipeline transportation, more precisely a condensate pipeline, in SKIKDA region. This identification was followed by a comparison of the results obtained previously, with respect to some aspects; we compared all hazards identified by both methods and classified them into categories, also comparing consequences and losses; we also compared the different steps of each method used. The study performed allows us to determine the main differences using the STPA and Bowtie methods for hazard identification on pipeline transport and highlights a complementary while using them in order to identify in a more exhaustive way the hazards associated with the system being studied. Their combination may be more useful for a thorough hazard identification.
