In a significant step toward sustainable maritime innovation, IINO Kaiun Kaisha, Ltd. (IINO Lines) and Norsepower have successfully equipped the Oceanus Aurora, a Very Large Gas Carrier (VLGC), with two Norsepower Rotor Sails™️each 20 meters tall and 4 meters in diameter. Custom-designed to meet the vessel’s specific air draught requirements, these innovative sails utilize the Magnus effect to enhance propulsion by harnessing wind power. This modern adaptation of the Flettner rotor minimizes fuel consumption, thereby cutting CO₂ emissions by approximately 4%.

This installation marks a notable advancement in reducing emissions and improving fuel efficiency in the shipping industry.Oceanus Aurora Delivered in March 2023 by Daewoo Shipbuilding & Marine Engineering Co., Ltd. (now Hanwha Ocean Co., Ltd.) in Korea, the Oceanus Aurora was originally constructed with provisions for rotor sail technology. The installation, carried out in Rotterdam, the Netherlands, in early November 2024.

IINO Kaiun Kaisha, Ltd. (IINO Lines) has announced plans to construct Japan’s first large methanol dual-fuel crude oil tanker at Nihon Shipyard Co., Ltd. (NSY). The vessel, a pioneering development in Japan’s maritime industry, is expected to be completed in 2027 and will be allocated for a charter contract with Idemitsu Tanker Co., Ltd., marking a significant advancement in environmentally sustainable shipping.

The design of the tanker has been formulated by a four-company consortium, including IINO Lines, Idemitsu Tanker, Nippon Yusen Kabushiki Kaisha (NYK Line), and NSY. This collaboration underscores the maritime industry's collective effort toward decarbonization.

The vessel will be equipped with dual-fuel technology, enabling it to use both methanol and conventional fuel oil. Additionally, it will feature a shaft generator that harnesses the rotation of the main propeller shaft to generate electricity. This innovation is expected to significantly reduce emissions of carbon dioxide (CO₂), sulfur oxides (SOx), nitrogen oxides (NOx), and particulate matter (PM), making it a critical step towards lowering environmental impact.
