Purpose Iran is currently among the countries with high energy consumption levels. Based on the statistics published on the country's hydrocarbon balance sheet, the industrial sector was the largest energy user of all the sectors, followed by the household and transportation sectors. Besides, production lines account for the highest percentage of the industrial sector energy consumption. Accordingly, this paper aims to investigate the effects of coordinated energy management and manufacturing strategies to increase energy management performance. Design/methodology/approach This paper collected the required information on energy management and manufacturing from the experts of petrochemical companies; and oil and gas refineries and then examined their relationship. Moreover, the questionnaire tool was used to measure the independent variable. Findings The evaluations showed that organizations with coordinated and uncoordinated strategies do not exhibit equal energy management performance. Organizations with a coordinated combination of strategies have higher energy management performance than those with an uncoordinated combination of strategies. Combinations such as 11, 22, 33 and 44 are among the more coordinated combinations, which lead to higher performance. Originality/value Reviewing the studies in this regard revealed that limited and a handful of research papers were carried out on organizations' energy management strategies. None of the existing research has considered energy management strategies as a subsystem of an organization or specified its coordination with manufacturing strategies. However, this research has delved into this issue and our findings confirm certain assumptions of past studies and contribute to evaluating its effects on energy management performance.

Today complicated and risky environment makes risk assessment and identification one of the main steps of proper project management and realization of project objectives. Marine construction projects are key and strategic projects, and their specific nature adds to their importance. This study aimed to propose a method for risk assessment and ranking critical risks in marine construction projects in Iran. To this end, the risk assessment team was formed to identify serious marine construction project risks using risk breakdown structure. Afterward, the team defined risk assessment measures. All risks were assessed in each criterion based on the Taguchi loss function. It allowed decision-makers to define a measurable risk threshold for each criterion and assess risks by developing a common language called loss score. Finally, critical risks were determined based on their priority. The results can be used to improve effective risk management, and consequently, project management.
