Received an order for a spare boiler pump for Yoshi-no-ura Thermal Power Plant from Okinawa Electric Power Company, Incorporated [Orders Received in December 2024]

Yoshi-no-ura Thermal Power Plant is located in Okinawa Prefecture, the southernmost end of Japan. On sunny days, the entire power plant can be seen from the World Heritage site Nakagusuku Castle with the background of the beautiful ocean.

This power plant is a high-efficiency combined cycle power generation plant and uses liquefied natural gas (LNG), which has relatively low environmental burden among fossil fuels. In this plant, many Torishima pumps, including four boiler feed pumps, are already in operation with ongoing scheduled maintenance. That has led to a stable operation without any major problems since their installation in 2012 even in Okinawa where the risk of salt damage is always present.

The spare pump ordered this time will play an important role when conducting an overhaul inspection of the boiler feed pumps. Previously, regular maintenance of each piece of equipment had to be completed within a limited inspection period, and it was difficult to schedule enough time to perform overhaul maintenance of the boiler feed pumps. The new spare pump will allow for rotation maintenance in which the pump being inspected is replaced with a spare, shortening the inspection period drastically.

A spare pump will also help to quickly establish a recovery system in case of unplanned work outside of scheduled maintenance or when an emergency occurs. Off-site maintenance in our factory during off-peak season will also help to secure sufficient maintenance periods and allow for detailed inspection and servicing.

Since last year, Yoshi-no-ura Power Plant has been actively working to reduce CO2 emissions by testing hydrogen co-combustion and other methods. With our forward-thinking initiatives and thorough maintenance, we are expected to contribute to stable power supply across Okinawa.
