Major accident prevention illustrated by hydrocarbon leak case studies: A comparison between Brazilian and Norwegian offshore functional petroleum safety regulatory approaches

Publication date: Available online 30 August 2019Source: Safety ScienceAuthor(s): Alex Garcia de Almeida, Jan Erik VinnemAbstractDespite laws, regulations, or risk management tools designed to avoid loss events, a hydrocarbon leak (HCL) in an offshore oil and gas platform1 is a major hazard event that reveals failures in risk control. In addition, similarities between different HCLs challenge the efficiency of current improvement mechanisms and the completeness of applied risk management practices. Accident causation models sustain that different roles in different levels, including regulators, companies, and the work environment, create the necessary conditions to a loss event, and therefore should be part of the accident analysis. This paper analyzes similar HCLs occurred in Norwegian and Brazilian offshore platforms to compare the regulatory approaches to risk control, aiming to identify influences related to the recurrence of HCLs in functional regulatory regimes (FRRs). As a result, each HCL among case studies consists of human errors that occurred while offshore crews were operating unsafe systems created by improper design or changes to address operational demands. An inappropriate context may support the impairment of safeguards that may not always be available or reliable in an environment which has as particular aspects the remoteness and the need to be self-sufficient. As a consequence, unsafe systems impose safety rules to offshore personnel and more relevance to ...
