Wärtsilä signs agreement for first zero-emission high speed ferries in US

Technology group Wärtsilä on Tuesday (28 November) said it has signed a strategic partnership agreement to provide its Fleet Electrification and Systems Integrator Services for a project to build the first zero-emission high speed ferries in the United States.

The fully electric vessels will be built for San Francisco’s Water Emergency Transportation Authority (WETA), the operator of the San Francisco Bay Ferry system.

The project, and several others Wärtsilä will work on under this partnership, are a part of the agency’s Rapid Electric Emission-Free (REEF) Ferry Program, a phased decarbonisation of high-speed, high-capacity ferry service in the San Francisco Bay. 

Wärtsilä will work within the WETA project team to finalise vessel and charging system concepts.

“We’re proud to operate the cleanest high-speed ferry fleet in the nation, but a zero-emission future for our system is within reach,” said WETA Executive Director, Seamus Murphy. 

“Wärtsilä’s expertise and experience will be incredibly valuable given the complexity our ferry decarbonisation program entails.”

“This is a major project within the maritime sector’s journey towards decarbonisation, and we are proud to be a part of it,” said Hanno Schoonman, Director of sales for AMER region, Wärtsilä Marine Power. 

“Wärtsilä joins an industry leading team tasked to develop newbuild battery electric vessels that combine innovative technology and sustainable practices. Wärtsilä is well qualified to provide this project support, and this agreement is a clear endorsement of our strong track record in systems integration and emission-free propulsion.”

After completing the conceptual phase, WETA will move on to the initial construction phase of a multi-vessel programme. This phase will involve the building of three smaller ferries with a capacity of approximately 150 passengers each and two larger ferries capable of carrying at least 300 passengers. 

Additionally, the scope of this phase will encompass the inclusion of battery charging floats. The construction of the first electric-powered vessel is slated to commence before the conclusion of 2023, with commercial operations expected to launch in 2025.

Mitsubishi Shipbuilding receives orders for Japan’s first methanol-fuelled RoRo cargo ship duo

Two ships will be built at the Enoura Plant of MHI’s Shimonoseki Shipyard & Machinery Works in Yamaguchi Prefecture, with scheduled completion and delivery by the end of fiscal 2027.

Mitsubishi Shipbuilding receives orders for Japan's first methanol-fuelled RoRo cargo ship duo

Mitsubishi Shipbuilding Co., Ltd., a part of Mitsubishi Heavy Industries (MHI) Group, on Wednesday (19 June) said it has received orders from Toyofuji Shipping and Fukuju Shipping for Japan's first methanol-fueled roll-on/roll-off (RORO) cargo ships. 

The two ships will be built at the Enoura Plant of MHI's Shimonoseki Shipyard & Machinery Works in Yamaguchi Prefecture, with scheduled completion and delivery by the end of fiscal 2027.

The ships will be approximately 169.9 meters in overall length and 30.2 meters in breadth, with 15,750 gross tonnage, and loading capacity for around 2,300 passenger vehicles.

A windscreen at the bow and a vertical stem are used to reduce propulsion resistance, while fuel efficiency is improved by employing MHI's proprietary energy-saving system technology combing high-efficiency propellers and high-performance rudders with reduced resistance. 

The main engine is a high-performance dual-fuel engine that can use both methanol and A heavy fuel oil, reducing CO2 emissions by more than 10% compared to ships with the same hull and powered by fuel oil, contributing to a reduced environmental impact. 

In the future, the use of green methanol(2) may lead to further reduction in CO2 emissions, including throughout the lifecycle of the fuel. Methanol-fueled RORO ships have already entered into service as ocean-going vessels around the world, but this is the first construction of coastal vessels for service in Japan.

In addition, the significant increase in vehicle loading capacity and transport capacity per voyage compared to conventional vessels will provide greater leeway in the ship allocation schedule, securing more holiday and rest time for the crew, thereby contributing to working style reforms.

Mitsubishi Shipbuilding, to address the growing needs from the modal shift in marine transport against the backdrop of CO2 reductions in land transportation, labor shortages, and working style reforms, will continue to work with its business partners to provide solutions for a range of societal issues by building ferries and RORO vessels with excellent fuel efficiency and environmental performance that contribute to stable navigation for customers.

Mitsubishi Shipbuilding launches LNG-fuelled Ro-Ro vessel “Trans Harmony Green”

Mitsubishi Shipbuilding Co., Ltd., a Mitsubishi Heavy Industries (MHI) Group company based in Yokohama, Friday (7 June) held a christening and launch ceremony for the TRANS HARMONY GREEN, the first of two LNG-powered roll-on/roll-off (RO/RO) ships under construction for Toyofuji Shipping Co., Ltd. 

The ceremony took place at the Enoura Plant of MHI's Shimonoseki Shipyard & Machinery Works in Yamaguchi Prefecture. 

The ship's handover is scheduled for late January 2025 following completion of outfitting work and sea trials. The TRANS HARMONY GREEN will serve as a RO/RO vessel on shipping routes in Asia.

Trans Harmony Green vessel

The TRANS HARMONY GREEN is approximately 195 metres in overall length, approximately 30.6 metres in breadth, and has gross tonnage of approximately 49,500. It can simultaneously transport about 3,000 passenger cars. 

The ship's main engine and main generator engine are high-performance dual-fuel engines each accommodating LNG or diesel fuel. 

Together these engines enable a greater than 25% reduction in CO2 emissions compared to ships with the same hull and powered by fuel oil, cutting SOx (sulphur oxides) emissions to near zero, thereby helping to reduce the vessel's environmental footprint.

LR AiP awarded to SDARI for ammonia-fuelled boxship design

Classification society Lloyd’s Register on Friday (7 June) said it has awarded Chinese design company Shanghai Merchant Ship Design & Research Institute (SDARI) with approval in principle for its ammonia-propelled 8,200 teu containership design.

Working in partnership with Mediterranean Shipping Co and MAN E&S as part of a joint development project, the design includes a 73,000 cbm Type C tank ammonia containment system, with the ammonia tank fitted with a dome inside its tank connection space. 

The design also features the MAN 6G80-C10.5 -LGIA Ammonia Fuelled Engine, which has a high-pressure selective catalytic reduction (HP-SCR) system and it Tier II/Tier III compliant.

Andy McKeran, LR Chief Commercial Officer, LR, said: “As the shipping industry looks more closely at ammonia as a future fuel option to reduce maritime greenhouse gas emissions, this joint development project between LR, SDARI, MSC and MAN E&S showcases the partners’ technical strengths and capability on containership and ammonia fuel designs.”

Mr Li Xin, Vice Director of SDARI, said: “As a leading ship designer in the maritime industry, SDARI has been focusing on low carbon solutions together with our reliable partners.”

“This JDP is an exciting one and offers a practical solution to the community which will help the fleet to reduce carbon emission significantly, and make shipping sustainable and successful.”

 “As always, SDARI will offer a competitive design and be a trustworthy partner to the industry during the journey to net-zero emissions.”
