[en] The present work deals with the study of heat transfer in the storage tanks of onshore regasification terminals and the impact that heat transfer has on them. To this end, a brief introduction to the current situation of the gas market is initially made, followed by an analysis of the facilities that operate in our country, which will be carried out with the support of SketchUp and AutoCad software. Among them, one will be selected to evaluate it and differentiate the equipment and elements that operate in it to, finally, proceed to carry out the pertinent calculations in terms of transfer analysis. The Engineering Equation Solver (EES) software will be used to carry out the calculations that show whether the plant operates efficiently under the previously established criteria of volume of Boil-Off gas (BOG) generated inside the tanks, and with this evaluates the heat transfer. Finally, a thermal simulation will be carried out with the SolidWorks software of a regasification tank, and the similarities and differences of the values obtained between the EES calculations and the data extracted from the simulation will be concluded. This will demonstrate that they have the ability to prepare analysis and synthesis of theoretical-practical problems, design and optimization of facilities related to the field of marine engineering, as well as detect the need to improve and innovate energy systems, using documentation and support material from various parts of the world through the research of articles, books and other material in various languages, including English, fulfilling the lines of work set for this master's thesis.

[gl] O presente traballo versa sobre o estudo da transferencia de calor nos tanques de almacenamento de terminais de regasificación onshore e o impacto que ten a transferencia de calor nos mesmos. Para iso inicialmente faise unha breve introdución á situación actual do mercado do gas, seguido da análise das instalacións que operan no noso país que se realizará con apoio dos softwares SketchUp e AutoCad. De entre elas seleccionarase unha para avaliala e diferenciar os equipos e elementos que operan para, finalmente, proceder á realización dos cálculos pertinentes en materia de análise de transferencia. Empregarase o software Engineering Equation Solver (EES) para a realización dos cálculos que demostren se a planta opera de forma eficiente baixo os criterios previamente fixados de volume de Boil- Off gas (BOG) xerado no interior dos tanques, e con iso avaliar a transferencia de calor. Finalmente, realizarase unha simulación térmica co software SolidWorks dun tanque de regasificación, e concluirase sobre as similitudes e diferenzas dos valores obtidos entre os cálculos do EES e os datos extraídos da simulación. Con iso demostrarase que se conta coa capacidade de elaborar análise e síntese de problemas teórico prácticos, deseño e optimización de instalacións relacionadas co ámbito da enxeñería mariña así como detectar a necesidade de mellorar e innovar sistemas enerxéticos, empregando para iso documentación e material de apoio de diversos lugares do mundo mediante a investigación de artigos, libros e demais material en diversos idiomas, entre eles o inglés, dando cumprimento ás liñas de traballo marcadas para leste traballo fin de máster.
