ENERGY EFFICIENCY ON SHIPS. STRATEGIC APPROACH

Abstract

Introduction. The shipping industry is a critical component of the global economy, with around 90% of the world's trade being transported by ships. However, the industry also has a significant environmental impact, contributing to around 2.5% of global greenhouse gas emissions. As such, there is a growing need to improve the energy efficiency of ships to reduce their environmental impact and comply with increasingly stringent regulations. Purpose. This article will explore the various technologies and strategies available to improve energy efficiency on ships and provide a scientific analysis of their effectiveness. Results. Wind propulsion technologies, such as rotor sails or kite sails, can be used to reduce fuel consumption and emissions in the shipping industry. These technologies harness the power of wind to propel the ship, reducing the need for fossil fuels. While wind propulsion technologies are still relatively new, they have shown promising results in terms of reducing fuel consumption and emissions. Energy management systems can also be used to optimize the operation of a ship's engines and equipment and improve energy efficiency. Energy management systems can also help reduce maintenance costs and extend the lifespan of the ship's equipment. Hybrid propulsion systems, which combine two or more power sources, can also help improve the energy efficiency of ships. This can reduce fuel consumption and emissions, especially during low-load conditions. Hybrid propulsion systems can also help improve the overall performance and reliability of the ship's power system. Conclusions. 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.
