The Global Centre for Maritime Decarbonisation (GCMD) and its appointed consultant, DNV Maritime Advisory (DNV) supported by Surbana Jurong (SJ) and the Singapore Maritime Academy (SMA) at the Singapore Polytechnic (SP), have completed an ammonia bunkering safety study that was commissioned in January 2022, according to GCMD on Thursday (28 April).

The risks identified for conducting pilots in the Port of Singapore were found to be low or mitigable, thus paving the way for a pilot project to take place at three identified sites.

GCMD said despite its toxicity and associated risks, green ammonia is one of the potential fuels that can decarbonise the shipping industry.

“With the completion of this study, local regulatory authorities will be able to use the report and its guidelines to deliberate the undertaking of an ammonia bunkering pilot," it added.

Because ammonia-fuelled vessels are not available today, ammonia transfers in the port waters of Singapore will be first carried out with ammonia carriers to ready stakeholders of the ecosystem for an actual bunkering pilot when ammonia-fuelled vessels are on the water.

A robust set of safety guidelines and operational envelopes

The 9-month-long study has resulted in a report titled “Safety and Operational Guidelines for Piloting Ammonia Bunkering in Singapore”. The study analysed capacity needs and feasible operating concepts; it recommends suitable sites for pilots, and identifies hazards, key risks and mitigation measures. The report also estimated the total capital expenditure for the additional infrastructure buildout needed to operationalise ammonia bunkering at two land-based sites.

For the study, the DNV consortium consulted extensively with 22 Study Partners and obtained feedback from more than 130 Industry and Consultation Alignment Panel (iCAP) members. Conversations with relevant regulators helped refined the analyses. Given the Port of Singapore’s proximity to dense residential areas and operations that see more than 1,000 ships a day, the stringent guidelines to pilot ammonia bunkering that were developed in this GCMD study will likely be applicable to piloting ammonia bunkering at ports elsewhere.

Safety risks can be mitigated

More than 400 potential risks were identified and assessed based on four technically feasible operational concepts: breakbulk and bunkering at anchorage, as well as shore-to-ship transfer and cross-dock transfer at two land-based sites for potential ammonia bunkering. The consortium found the identified risks to be manageable with mitigation measures. The analysis showed that individual fatality and injury risks depend on the flow rate of ammonia, the number of transfer operations, duration per transfer operation, and the length of piping and transfer arms.

Given the small number of ammonia bunkering pilots that would be carried out annually, the individual risks thresholds set by the Major Hazards Department of the Ministry of Manpower are not expected to be triggered. Coarse Quantitative Risk Assessment (QRA) using a deterministic dispersion model revealed a safety zone of 200 to 400 m for breakbulk and bunkering operations at anchorage with flow rates up to 700 cbm/hr.

Professor Lynn Loo, CEO of the Global Centre for Maritime Decarbonisation, said: “This report will inform and enable a GCMD pilot involving ship-to-ship transfer of ammonia in the port waters of Singapore. We are aiming for the first transfer of ammonia to take place by end 2023, subject to obtaining the greenlight from the relevant regulatory agencies. Since ammonia-fuelled vessels are not yet available, we will be conducting the pilot with proxy assets to gain stakeholder competence and confidence so an actual bunkering exercise can commence when ammonia-fuelled vessels are on the water.”

Knut Ørbeck-Nilssen, CEO of DNV Maritime, said: “Ammonia holds potential for a future maritime fuel and thus one pathway for the maritime industry’s decarbonization journey. This project will help lay the safety considerations for ammonia bunkering. Safety lies at the heart of the guidelines that DNV helped to develop for this pilot in Singapore. Further pilots and studies are key to understand, assess and mitigate safety risks associated with using ammonia fuel onboard the world fleet.”

Tan Wooi Leong, Managing Director, Energy & Industrial, Surbana Jurong, said: “The study will bolster Singapore’s position as an innovative and responsible global maritime hub leader as it seeks to decarbonise the maritime industry. This study gives authorities a very practical, comprehensive view of the costs associated with designing a port that supports the safe transfer and storage of this toxic but game-changing alternative fuel.”

Beyond the study

In preparation for the next phase of the GCMD project to execute an ammonia bunkering pilot in Singapore, GCMD is working with SMA to operationalise the manpower development framework for training operators to handle ammonia as a marine fuel. Already, SMA has incorporated elements from the study to develop the first training course on the handling of ammonia under the International Code of Safety for Ships Using Gases or Other Low-flashpoint Fuels (IGF Code) and industry guidelines. This course took place for the first time in March 2023, and registration is open for its next intake.

Capt Chatur Wahyu, Acting Director of Singapore Maritime Academy (SMA), Singapore Polytechnic (SP) said: ”SMA had recently successfully conducted the Advanced IGF course where the topic on ammonia handling was covered during the programme. SMA is committed to contributing in the efforts towards green shipping and using ammonia as a future source of clean energy for the maritime industry. We hope to upskill more maritime talents to meet the needs of the industry’s changing landscape.”

GCMD is also working closely with Oil Spill Response Limited to develop emergency response procedures, and will be sharing the full report with the Singapore Standards Council to support the development of a technical reference on ammonia bunkering.

A public version of this report, with land-based site identity and site-specific information i.e., their specific operational risk analyses and infrastructure readiness, redacted for commercial sensitivity considerations, is openly available.

The full report will be made widely available at a later date.

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.
