DNV launches a comprehensive slide show detailing strategies to maximise energy efficiency in tankers, while aligning with regulatory demands
DNV, a global leader in maritime advisory services, has launched a detailed slide show titled Maximizing Energy Efficiency in the Tanker Segment. This presentation is designed to guide tanker operators and stakeholders through a variety of strategies aimed at enhancing energy efficiency, aligning with regulatory requirements, and reducing operational costs.
The slide show begins by underscoring the critical importance of energy efficiency within the maritime industry. With mounting regulatory pressures and the increasing focus on sustainability, tanker operators are seeking innovative solutions to enhance operational performance while minimising environmental impact. A significant portion of the presentation is dedicated to explaining the current regulatory framework.
This includes International Maritime Organization’s (IMO) decarbonisation targets and the upcoming European Union Emissions Trading System (ETS), which is expected to impose substantial costs on CO2 emissions from ships starting in 2024. These regulations necessitate that tanker operators adopt comprehensive energy efficiency measures to remain compliant and economically viable.
In the slideshow, DNV highlights several operational measures that can be implemented to achieve immediate efficiency gains. These include optimising machinery operations, enhancing hydrodynamic performance through regular hull cleaning and propeller polishing, and optimising trim and draught for better fuel efficiency. Additionally, improved voyage planning and fleet utilisation are emphasised to reduce waiting times and optimise energy consumption during port operations.
Beyond operational tweaks, the slideshow delves into technical advancements that promise significant efficiency improvements. Key measures discussed include the adoption of electronic autotuning for engines, waste heat recovery systems, and the use of variable frequency drives for pumps and fans.
The presentation also covers propulsion efficiency enhancements, such as high-efficiency propeller designs and energy-saving devices and explores the potential of alternative energy sources.
DNV examines the feasibility of biofuels, shore power and hybrid systems that integrate batteries with traditional engines. These alternative sources not only help in reducing emissions but also offer long-term cost benefits.
To illustrate the practical application of these measures, DNV provides several real-world case studies. One example includes the use of hybrid power systems in shuttle tankers, which has resulted in a 38% increase in efficiency.
Another case study focuses on medium-range tankers utilising methanol and LNG, highlighting the benefits and challenges associated with these fuels.
The slide show also examines strategic fuel choices and their economic implications. By comparing various fuels such as LNG, biofuels, and e-fuels, DNV provides a comprehensive analysis of their cost-effectiveness and environmental impact and emphasises the importance of fuel flexibility to adapt to future regulatory changes and market dynamics.
Looking ahead, DNV projects continued advancements in energy efficiency technologies and practices.
