Singapore-based shipyard Sembcorp Marine Ltd on Tuesday (15 March) said it has completed fabrication of the first of three identical battery-operated roll-on/roll-off passenger (Ropax) ferries for Norled AS a Norwegian ferry operator.

The Group was awarded a contract by Norled to design and construct three identical battery-powered Ropax ferries, based on the proprietary design of LMG Marin AS, a wholly-owned subsidiary of Sembcorp Marine.

The vessels’ design is optimised according to Norled operational requirements incorporating energy-efficient solutions throughout the ferries. These include quick-connection shore charging plugs; auto-mooring; auto-cross; efficient hull, propulsion and heat recovery systems; as well as minimised hotel and auxiliary loads.

The vessels will operate normally on zero-emission, powered by lithium-ion batteries at a service speed of 10 knots. When required, they can run on combined battery-diesel hybrid backup modes. The batteries will be charged and recharged using green hydro-electric power.

The design of the 82.4-metre long multi-deck, double-ended ferries, each with a capacity for 300 passengers and crew, as well as 80 cars or a combination of up to 10 cars and 10 trailer trucks, also took into consideration passengers’ comfort and working conditions for the crew.

When launched into operation for Norled’s shortsea Hella-Vangsnes-Dragsvik connections in Norway, it is expected to fulfil Norled’s objective to contribute to emission reductions through the introduction of innovative new vessels equipped with zero-emission technology.

Torbjorn Bringedal, LMG Marin Managing Director, said: “LMG Marin offers a wide range of designs and technologies for sustainable ship operations, including LNG, battery, hydrogen, ammonia and hybrid propulsion systems. We are very pleased to be able to use our proprietary design to support Norled’s green objectives with specific customisation for the vessels’ operating environments.”

Tan Heng Jack, Sembcorp Marine’s Head of Specialised Shipbuilding, said: “To serve efficiently as a ferry vessel, the design took into consideration the vessel’s operational profile and schedule, as well as design imperatives of passenger safety and comfort, and conducive working conditions for ferry staff. The first of the three vessels will soon be part of Norled’s service fleet in Norway.”

Wong Weng Sun, Sembcorp Marine President & CEO, said: “The demand for passenger ferries is anticipated to increase owing to a wide range of factors including the emerging trend of ferries as a viable alternative transport, development in marine fuel technologies, and inclination of consumers towards luxury marine travel.”

Wong added, “Sembcorp Marine, with its extensive track record and suite of proprietary designs for various types of ships and offshore engineering solutions, will continue to strategically position the Group strongly to support the maritime industry’s transition towards renewable energy and the adoption of green technologies. This latest project marks our commitment to our customer and their pursuit of green solutions for the industry.”

The remaining two Ropax ferries are expected to be ready in 2022.

EDF, LR and Arup launch tool scoring ports’ potential to produce and bunker electrofuels

Lloyd’s Register (LR) Maritime Decarbonisation Hub and Environmental Defense Fund (EDF), in collaboration with Arup, on Tuesday (28 November) introduced the Sustainable First Movers Initiative Identification Tool, a system to help shipping stakeholders align investment decisions that support the maritime energy transition away from fossil fuels.

The tool, which is presented in a preliminary findings report – The Potential of Ports in Developing Sustainable First Movers Initiatives – scores a port’s potential to produce and bunker electrofuels while delivering local environmental and community benefits in alignment with the global temperature target of 1.5 degrees Celsius set by the Paris Agreement.

“Ports can play an important role in kickstarting shipping’s decarbonisation process even before global policies are established,” said Marie Cabbia Hubatova, Director, Global Shipping at Environmental Defense Fund.

“By considering the impact sustainable first mover initiatives can have on port-side communities, climate, environment and economies, resources can be better directed to locations where these initiatives will make the biggest difference.”

With close to two billion people living near coastal zones globally, the role of, and impacts on local port communities must be intentionally considered as the sector decarbonises globally. Ports can play a crucial role in ensuring shipping decarbonisation efforts are done in a way that has positive impacts on port communities.

The preliminary phase of the Sustainable First Movers Initiative Identification Tool analyses 108 ports in the Indo-Pacific region according to five criteria including land suitability, air quality, renewable energy surplus, economic resilience and ship traffic.

It is also applied to three different port scenarios, including ports exploring fuel production and bunkering, ports exploring fuel exports, and ports exploring fuel imports and bunkering. The combined criteria and scenario evaluation determines which ports have the greatest potential (high potential) for sustainable first mover initiatives to lead to significant emissions reductions and positive impacts in nearby communities, such as improved air quality and economic resilience.

“The transition to clean energy supply for shipping can be achieved only if stakeholders act together. Identifying potential port locations is the first step in this process,” said Dr Carlo Raucci, Consultant at Lloyd’s Register Maritime Decarbonisation Hub. “This approach sets the base for a regional sustainable transition that considers the impacts on port-side communities and the need to avoid regions in the Global South lagging behind.”

Regions in the Global South are fundamental in driving the decarbonisation of shipping. To make this transition effective, the rate at which different countries adopt and scale up electrofuels must be proportional to the difference in capital resources globally to avoid additional costs being passed on to local communities. Sustainable first mover initiatives can play an important role in making this happen by ensuring the sector’s decarbonisation is inclusive of all regions and by engaging all shipping stakeholders, including port-side communities.

“There’s a huge opportunity for early adopter shipping decarbonisation initiatives to unlock benefits for people and planet – shaping the way for a more equitable transition in the 2030s,” said Mark Button, Associate, Arup. “Our collective approach shows that taking a holistic view of shipping traffic, fuel production potential and port communities could help prioritise action at ports with the greatest near-term potential.”

The tool can be customised according to stakeholders’ needs and goals and is dependent on scenario desirability. The next phase of this work will include the selection and detailed assessment of 10 ports to help better understand local needs and maximise the value offered by sustainable first mover initiatives. 

LR and EDF carried out a joint study on ammonia as shipping fuel, and LR and Arup have collaborated on The Resilience Shift study focused on fuel demand for early adopters in green corridors, ports, and energy systems, amongst many other projects.

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.
