TSUNEISHI SOLUTIONS TOKYOBAY Co., Ltd. (Head Office: Minato-ku, Tokyo; hereinafter “T-SOL”) delivered the first Low-flashpoint Fuel (MeOH) Supply System (“LFSS”) for medium- and low-speed diesel engines at the end of May 2026. The LFSS received Approval in Principle (“AiP”) from ClassNK in April 2024. This LFSS is the first unit of T-SOL’s proprietary LFSS developed in-house and will be installed on a Kamsarmax bulk carrier, marking its first application on an actual vessel following the AiP granted by ClassNK.

An LFSS is designed to safely and reliably supply alternative fuels with low flashpoints, such as methanol, to a vessel’s main engine.

The LFSS delivered by T-SOL has been developed specifically for medium- and low-speed diesel engines and features a simple and compact design in terms of its main components, dimensions and weight. The system is equipped with key components manufactured by Japanese suppliers, enabling the provision of instruction manuals in Japanese as well as prompt and flexible responses to customer enquiries.

As the LFSS is assembled in Japan, customers adopting T-SOL’s LFSS are not required to attend Factory Acceptance Tests (FAT) overseas or arrange for engineers from overseas equipment manufacturers to travel to Japan, thereby helping reduce both costs and operational burdens for customers. T-SOL also provides on-site technical support during commissioning and testing.

With the tightening and introduction of environmental regulations, marine fuels are entering a period of transition from heavy fuel oil to alternative fuels, including methanol. The transition requires new expertise and considerable time for technical evaluation, increasing the burden on customers. Drawing on the expertise of its experienced engineers, T-SOL provides comprehensive support throughout each customer’s transition to alternative fuels.

Following the delivery of its first LFSS, T-SOL will continue to work to ensure a stable supply of LFSS units while advancing the research and development of technologies that contribute to greenhouse gas (GHG) emissions reduction, including engineering solutions for other alternative fuels. Through these initiatives, T-SOL aims to contribute to the advancement of the maritime industry in Japan and overseas, while supporting the achievement of carbon neutrality by 2050.
