Recent research led by Tarek A. Ashry, a Marine Chief Engineer from Egypt, has shed light on the significant potential for reducing CO2 emissions in Very Large Crude Carriers (VLCCs) through the implementation of the Ship Energy Efficiency Management Plan (SEEMP) and the Energy Efficiency Design Index (EEDI). This study, published in the Alexandria Engineering Journal, highlights both the operational and technical measures that can be employed to enhance the environmental performance of oil tankers.
The research conducted a comprehensive field study across three phases involving VLCCs. The first two phases evaluated existing vessels before and after the enforcement of SEEMP, while the third phase focused on new VLCCs equipped with advanced energy-efficient technologies, adhering to both SEEMP and EEDI guidelines. The results were striking: fuel consumption dropped by 82.6%, CO2 emissions decreased by 66.8%, and the Energy Efficiency Operational Indicator (EEOI) improved by 71.5% in the third phase compared to the first. Moreover, the overall performance of vessels in phase three showed a remarkable increase of 46.6% over those in phase two.
Ashry noted the importance of these findings, stating, “SEEMP and EEDI have brought about significant reductions in the accumulation of Greenhouse Gases (GHGs) and provided a real momentum for the efforts towards a greener maritime world.” This indicates a clear pathway for the shipping industry to align with global sustainability goals while also enhancing operational efficiency.
The implications for the maritime sector are profound. As regulations tighten and the demand for eco-friendly operations grows, companies that adopt these measures stand to benefit significantly. Not only do these practices lead to reduced emissions and fuel costs, but they also position shipping firms as leaders in sustainability, potentially attracting environmentally conscious clients and investors.
Furthermore, the integration of innovative technologies into new VLCC designs presents commercial opportunities for shipbuilders and technology providers. By investing in energy-efficient solutions now, stakeholders can ensure compliance with future regulations and capitalize on the growing trend toward sustainable shipping practices.
As the industry moves toward a greener future, the findings from Ashry’s research underline the critical role of SEEMP and EEDI in achieving substantial environmental improvements. The study serves as a call to action for maritime professionals to embrace these strategies, ensuring that the shipping industry not only meets regulatory requirements but also contributes positively to the global environment.
