When it comes to the modification of a fossil- to bio-refinery, the reuse of a standardized design is unprecedented. Factor in the presence of stakeholders with varying interests and opinions equates to a highly complex system. Alignment of the stakeholders is therefore recognized to be necessary. The possibilities on how to make such a refinery modification less complex through the alignment of the relevant stakeholders became the goal of this study. To achieve it, a framework has been developed, and the necessary data to construct it shall come from interviews with experts from the field and literature reviews. The findings show that alignment of the stakeholders on the requirements that need to be considered for
modification projects can help in increasing the success of the implementation of a
standardized refinery modification design. To test the framework, it was implemented in an engineering company’s refinery modification project. Out of the framework implementation advice has been formulated on how to further help the engineering company to become successful in aligning their stakeholders and to effectively implement a standardized refinery modification design.
