A consortium comprising Idemitsu Tanker Co., Ltd., IINO Kaiun Kaisha, Ltd., NYK, and Nihon Shipyard Co., Ltd. has revealed a design concept for Japan's first very large crude oil carrier (VLCC) utilizing methanol as an alternative fuel. The VLCC, known as the 'Vessel,' will feature a dual-fuel main engine, shaft generator, and optional wind propulsion system to achieve a CO2 reduction of over 40% compared to the Energy Efficiency Design Index (EEDI) regulations. This reduction surpasses Phase 3 requirements set for 2025. The adoption of methanol is anticipated to play a vital role in reducing CO2 emissions by approximately 15% in comparison to traditional fuel oil, aligning with the International Maritime Organization's greenhouse gas emission reduction strategy. Moreover, by utilizing green methanol such as bio-methanol and synthetic methanol produced from renewable energy sources and captured CO2, the Vessel can achieve net zero CO2 emissions. The four collaborating companies, prominent in Japan's energy transportation sector, plan to conduct further studies based on the design concept to work towards the industry's goal of achieving carbon neutrality by 2050. They also aim to strategically place orders for constructing eco-friendly VLCCs and assign these vessels to transport crude oil for Japanese refineries in a timely manner. The initiative marks a significant step towards sustainable shipping practices and environmental stewardship in the maritime industry.
