Tugboat company Tokyo Kisen Co., Ltd. and shipping solution provider e5 Lab Inc. on Monday (30 May) said they have held a naming and launching ceremony of the electric tugboat Taiga, currently under construction at Kanagawa Dockyard Co., Ltd. 

The Taiga is powered by an electric propulsion system that combines e5Lab-developed large-capacity lithium-ion batteries and a diesel engine. 

It is an eco-ship designed to protect the environment in areas surrounding the ports of Yokohama and Kawasaki, and also a crew-friendly tugboat, not only achieving low/zero emissions of CO2, NOx, SOx, and particulate matter (PM) from the vessel but also reducing noise and vibration for an improved working environment.

IHI Power Systems Co., Ltd.  participated in the development of the tugboat as the system integrator and supplier of the ship’s Electric Propulsion System. It is the first tugboat to adopt IHI Power Systems’ L-Drive propulsion system.

The system also marks the first use of ABB’s DC Grid in Japan. In combination with the large-capacity lithium-ion batteries, it delivers higher efficiency than conventional electric propulsion systems.

In addition, it can be upgraded for even greater energy efficiency by analysing important parameters such as the charge-discharge power of lithium-ion batteries and propulsion motor output, along with fuel consumption of the diesel engine.

The project team also collaborated with OSD-IMT, a group company of Damen Shipyard (the Netherlands), for concept design of the tugboat to improve the crew’s operating performance as well as living environment.

In recognition of these advancements, the tugboat construction project was adopted as subsidy project of “Utilizing AI/IoT, etc. and More Efficient Transport Promotion Project Grant Subsidy (Coastal Ship Innovative Operational Efficiency Demonstration Projects)” by Japan’s Ministry of Economy, Trade and Industry (METI) and Agency for Natural Resources and Energy.

Initially the team considered equipping the tugboat with hydrogen fuel cells for enhanced environmental performance, and conducted a risk assessment (HAZID analysis) in cooperation with the project partners, but decided not to adopt the cells.

The Taiga is slated for completion in December 2022, and will operate mainly in the ports of Yokohama and Kawasaki as a harbor tug after delivery. In addition, installation of power supply equipment on a floating pier designed especially for the Taiga will be completed when the tug enters service.

Osaka Gas launches shore-to-ship LNG bunkering service at its terminal

Osaka Gas on Monday (21 April) said it has launched its shore-to-ship LNG bunkering service, becoming the first gas utility company in Japan to offer liquefied natural gas (LNG) at its terminal to vessels.

The first delivery took place today at Osaka Gas’ Senboku LNG Terminal in Takaishi City, Osaka Prefecture, where LNG was supplied to Verde Heraldo, a bulker operated by Mitsui OSK Lines (MOL). 

Manifold Times previously reported that the bulker will sail under long-term transport contracts to supply raw materials for JFE Steel Corporation's mills. 

With the launch of the shore-to-ship service, in addition to its existing truck-to-ship LNG bunkering service—operational since 2019—Osaka Gas enhances its LNG fuel delivery capabilities to address the current scarcity of facilities in Japan that can supply LNG to vessels. 

The company’s future plans include the introduction of a ship-to-ship LNG bunkering service utilising a dedicated LNG bunkering vessel, scheduled to commence in fiscal 2026.

These supply methods aim to provide a stable and flexible LNG fuel supply to an increasing number of LNG-fuelled vessels as the maritime industry transitions away from heavy fuel oil.

This growth in LNG-fuelled vessels is driven by global decarbonisation trends and the International Maritime Organization’s target to achieve net zero greenhouse gas emissions by 2050. Through its LNG bunkering services, Osaka Gas is well-positioned to contribute to maritime industry sustainability.

Japan: J-ENG begins co-firing of first full-scale marine engine with ammonia

Japan Engine Corporation (J-ENG) on Monday (21 April) said the first Japanese-developed and manufactured commercial full-scale, low-speed, ammonia-fuelled two-stroke engine has started co-firing operation with ammonia, which will be installed in a vessel. 

J-ENG is developing the engine under the “Green Innovation Fund Project: Next-generation Ship Development” of the New Energy and Industrial Technology Development Organization (NEDO). 

Since May 2023, when J-ENG started the world's first ammonia co-firing operation of a large, low-speed, two-stroke engine in a test engine, J-ENG has obtained many results and knowledge, including stable operation at high ammonia co-firing rates and safe handling of ammonia, through various test operations over a period of about a year and a half. 

J-ENG will conduct verification operations on the full-scale engine and plans to ship the engine in October of this year. The engine will be installed on an Ammonia-fuelled Medium Gas Carrier (AFMGC) and then demonstration operations of the vessel will be carried out then.

In order to accommodate a wide variety of ammonia-fueled vessels, J-ENG is also concurrently developing an ammonia-fueled engine with a cylinder bore of 60cm, following the first engine with a 50cm cylinder bore mentioned above, for several promising follow-on projects.

Furthermore, after achieving the development and social implementation of these engines, the company has decided to construct a new plant with the support of a subsidy project by the Ministry of the Environment and the Ministry of Land, Infrastructure, Transport and Tourism through the GX Economic Transition Bonds. 

The new plant, which is scheduled for completion in 2028, will expand the production of ammonia fuel engines (in the product mix with fuel oil engines) and promote the spread and expansion of zero-emission ships.

“J-ENG, as a first mover of next-generation fuel engines, will contribute to the development of the Japanese shipping and shipbuilding industries through the early launch and expansion of these engines, and at the same time, contribute to the reduction of greenhouse gases (GHG) in international shipping and the achievement of carbon neutrality by 2050,” the company said on its website.
