The scarcity of data about “the probability and severity” of the Risk Factors (RFs) and “the usability and effectiveness” of the Risk Mitigation Methods (RMMs) in Oil and Gas Pipelines (OGPs) are hindering the efforts of risk mitigations in these projects. Consequently, this paper aims to develop a questionnaire survey to collect these require data to analyze the RFs and effectively evaluate the RMMs. Firstly, documents qualitative analysis were carried out to identify the RFs and RMMs in OGPs projects in different countries worldwide. Secondly, an industry-wide questionnaire survey was found to be an effective quantitative approach to analyze the “probability and severity” levels of the RFs and to evaluate the “usability and effectiveness” degrees of the RMMs. A pilot-like survey was significantly needed to improve the clarity of the questions and revise the ambiguous questions. As well as, to add the necessary queries and discard the unnecessary ones. Moreover, the pilot-like survey was used to test the functionality of the rating scales; and to improve the overall design of the survey. This survey filled by a number of experts in OGPs projects; their feedback was found helpful to write the final draft of the survey. The findings of this paper was a questionnaire survey that will be used in ongoing research about mitigating the RFs in OGPs projects. Furthermore, a few authors explained their procedure of designing such survey. Therefore, researchers in this field could use the findings and comments of this to design their surveys
