Wärtsilä Signs Agreement With Kuribayashi Steamship For Deployment Of Innovative Gate Rudder Technology

The technology group Wärtsilä, with the consent of all joint Japanese patent holders developing gate rudder technology, has announced the signing of a Licence and Co-operation Agreement with Kuribayashi Steamship Co for future development, sales and servicing of the gate rudders.

In addition to Kuribayashi Steamship Co, the other patent holders are Kamome Propeller, the National Institute of Maritime, Port and Aviation Technology (NIMPAT, Japan), Yamanaka Shipbuilding, and Professor Noriyuki Sasaki. As an authorised license holder and partner, Wärtsilä intends to fully integrate gate rudders within its propulsion product designs and focus on global markets outside Japan. The agreement was signed on 28 February 2020.

By offering gate rudders as an integral part of Wärtsilä’s propulsion offerings for newbuild vessels, compliance with the Energy Efficiency Design Index (EEDI) will be further facilitated.

The technology is available for both new build and existing vessels. As an integral part of the design, it will realise synergies in capital and operational savings for ship owners by increasing fuel efficiency, improving manoeuvrability and course stability in both calm and rough sea conditions, while also reducing noise and vibration.

This new collaborative partnership will accelerate the deployment of gate rudder systems across all vessel classes. By combining Wärtsilä’s propulsion and machinery integration expertise with the Japanese patent holders’ gate rudder technology and know-how, this new technology will become accessible throughout the marine sector, with ship owners benefiting from the technology concepts.

Speaking on the agreement, Lars Anderson, Director, Propulsion, Wärtsilä Marine, said: “At Wärtsilä we are doing our outmost to support our customers as they look for new technologies to reduce operating costs and improve the environmental sustainability of their operations. We see great potential in this gate rudder technology collaboration. Today’s agreement enables us to support the building of better and more sustainable vessels already today, and Kuribayashi Steamship and the Japanese patent holders are the ideal partners to help us realise this goal.”

Sadatomo Kuribayashi, Chairman of Kuribayashi Steamship Co. Ltd., added: “Today’s agreement with Wärtsilä is a major step forward in introducing gate rudder technology to the global market, and it helps the shipping industry’s initiatives for sustainable shipping and reduced operating costs. An innovative approach has been taken in creating this new solution for the maritime industry. The first evaluations of vessel performance on Japanese coastal vessels have shown a significant improvement in efficiency and manoeuvrability. We see Wärtsilä, with a strong global presence, and sharing the same commitment for developing cleaner, more sustainable, and efficient marine shipping, as being the ideal partner.”
