Synopsis
This article will explore the various technologies and strategies available to improve energy efficiency on ships and provide a scientific analysis of their effectiveness. The research objectives include development of a comprehensive model for assessing vessel energy efficiency in the context of navigation operations, identification and analysis of key factors affecting fuel consumption during vessel's voyage, formulation of practical recommendations for implementing energy-efficient navigation methods. An innovative approach is presented to improving vessel energy efficiency through enhanced navigation methods, addressing the growing need for fuel consumption optimization in maritime transportation. Traditional approaches to vessel energy efficiency often focus on technical solutions, while the potential for optimization through improved navigation methods remains underexplored. The study introduces a comprehensive model for energy efficiency assessment that considers multiple operational factors affecting fuel consumption during vessel transit. It is provided a systematic approach to energy efficiency optimization, supported by mathematical models and practical recommendations for implementation. The results demonstrate the potential for significant reduction in fuel consumption through improved navigation methods, contributing to both economic efficiency and environmental sustainability in maritime operations. A method for increasing the energy efficiency of a vessel by minimizing the variance of the observation error with the introduction of an orthogonal decomposition of the distribution density of errors in navigation measurements is discussed. The results obtained can significantly increase the accuracy of the vessel's location and, as a consequence, improve its energy efficiency by reducing deviations from the optimal route. The proposed method for determining the ship's coordinates using the orthogonal decomposition of the error distribution density provides higher efficiency compared to the least square method.
Improving the energy efficiency of ships is an important step in reducing the shipping industry's impact on the environment. There are various strategies and technologies that can be employed to achieve this goal, including hull coatings, waste heat recovery, energy management systems, hybrid propulsion systems, and wind propulsion. While each strategy has its advantages and limitations, their combined use can help improve the overall energy efficiency of ships and reduce their impact on the environment.
