The global energy transition process has generated a set of modifications in the generation and consumption of energy. Environmental objectives have gained great relevance for regions, countries and companies. The fishing sector has been identified as having a broad environmental impact, which is why the transition to cleaner energy sources in this sector has been considered. One of the proposed strategies is based on the transition from the diesel engines of the ships to the use of liquefied natural gas (LNG), however, this transition requires guaranteeing the supply of fuel as well as the process of reconversion of units in operation and the impulse of LNG gas engines for new units. This work presents a proposal for the design of an LNG gas supply chain for the fishing industry in the State of Tampico in Mexico that allows evaluating the feasibility of the transition from the use of diesel to natural gas in fishing vessels. The main results show the feasibility of the transition in the fuel supply and economic and environmental benefits for the fishing industry. However, there is a significant challenge in converting units in operation to the use of natural gas due to the lack of public policies that promote and support its use in this sector.

全球能源转型过程在能源的生产和消费方面产生了一系列变化。环境目标已与地区、国家和公司密切相关。渔业部门已被确定为具有广泛的环境影响，这就是为什么要考虑在该部门向清洁能源过渡的原因。提议的策略之一是基于从船舶柴油发动机到使用液化天然气 (LNG) 的过渡，但是，这种过渡需要保证燃料供应以及运行中的装置的再转换过程和LNG 燃气发动机对新机组的推动。这项工作提出了一项为墨西哥坦皮科州的渔业设计液化天然气供应链的建议，该建议允许评估在渔船上使用柴油向天然气过渡的可行性。主要结果表明燃料供应转型的可行性以及渔业的经济和环境效益。然而，由于缺乏促进和支持天然气在该领域使用的公共政策，将运行中的装置转换为使用天然气存在重大挑战。
