Classification society American Bureau of Shipping (ABS) on Thursday (18 May) it will be using advanced modeling and simulation technologies to develop emergency response methods to assist ports and crew in responding to ammonia leaks or spills.

ABS said it is the first step towards a comprehensive and fast ammonia release response system, capable of predicting the behavior of an ammonia plume and directing emergency mitigation services accordingly.

“Thanks to its potential for zero-carbon emissions, ammonia is widely viewed as a promising fuel solution for a more sustainable industry but its high toxicity presents significant operational challenges on board and ashore,” it said.

“ABS has always been a safety pioneer, so we are well placed to tackle the significant operational risks presented by this critical piece of the net-zero jigsaw puzzle. Our advanced simulation and modeling approach is already shining a light on the unique behaviors of this fuel in a range of scenarios,” said Christopher J. Wiernicki, ABS Chairman, President and CEO.

“This will inform the strategies of ports, crews and emergency services and enable immediate and informed response to an ammonia release. This is the sweet spot for ABS, the nexus of advanced technology, regulation and safety and we are on course to deliver a significant safety development for the industry.”

ABS combined modeling and simulation with Computational Fluid Dynamics (CFD) to create a high-fidelity model designed to replicate ammonia dispersion patterns in the engine room. Using this new model, ABS specialists studied the impact of various ventilation approaches on the behavior of ammonia plumes resulting from leakages from the fuel lines, revealing optimum methods to vent the ammonia plume.

A dynamic model will be able to swiftly predict the response of an ammonia plume to a range of parameters such as wind speed and direction, humidity, cubic meters per second and relationship of the vessel to port. In addition to dispersion analysis, agent-based discrete event simulations to study the response of crew, port authorities, and emergency services after dispersion will be conducted.

Hong Kong-based Sun Ferry takes delivery of diesel-electric ferry “Xin Ming Zhu 30”

Global digital shipbuilder Incat Crowther on Wednesday (19 March) said Hong Kong-based ferry operator Sun Ferry has taken delivery of Xin Ming Zhu 30, a new, 35-metre diesel-electric ferry.

The new vessel, designed by Incat Crowther and constructed by Guangzhou-based shipbuilder AFAI Southern Shipyard, is the third vessel to join a fleet of seven new vessels designed by Incat Crowther for the mass transit operator.

The vessel will serve inter-island commuter and tourism operations across Hong Kong, connecting Peng Chau, Mui Wo, Chi Ma Wan and Cheung Chau.

The 300-seat passenger ferry boasts Veth azimuth thrusters that provide high manoeuvrability at operating speeds of 14 knots. The adoption of this technology makes the vessel suitable for berthing at piers on inter island routes.

The vessel is also fitted with 72 solar panels providing 7.5 kilowatts of on-board power.

Sam Mackay, Technical Manager at Incat Crowther, said: "This vessel reflects Sun Ferry’s commitment to future focused design solutions that not only meet operational needs, but that exceed customer expectations.”

“With diesel-electric propulsion, solar technology, and passenger-centric design, it sets a new benchmark for sustainable and efficient ferry services in Hong Kong.”

The delivery of the 35-metre hybrid vessel follows the delivery of two 45-metre conventional diesel-powered vessels to Sun Ferry. The final three vessels, all 45-metre vessels, will be delivered by the end of 2025. All vessels in the fleet have been designed by Incat Crowther and built by AFAI Southern Shipyard.

PRIO delivers Eco Bunkers B30 to two cargo ships at ports in Portugal

Biofuels producer PRIO on Wednesday (19 March) said it carried out Eco Bunkers B30 fuel deliveries to shipping company Briese Chartering in collaboration with its partner UFS Unites Fuel Services this month.

On 3 March, PRIO supplied the biofuel to cargo vessel BBC Lisbon at the Port of Aveiro and to another cargo vessel, ANNA, at the Port of Leixões on 18 March.

“With these two Eco Bunkers B30 deliveries, a product containing 30% renewable raw materials, PRIO enabled Briese Chartering to reduce around 60 tons of CO2 in just two port calls in Portugal,” it said in a social media post.

“Produced at PRIO’s Aveiro plant, biodiesel has the potential to reduce GHG emissions by approximately 88% compared to fossil fuels.”

“PRIO has been demonstrating its commitment to decarbonising the maritime sector by supplying more sustainable products, ranging from 1% to 100% renewable content.”

Manifold Times previously reported PRIO launching its ECO Bunkers B30 biofuel in partnership with Norwegian Cruise Line Holdings and World Fuel Services.

PRIO previously launched ECO Bunkers B15, a green fuel for ships with 15% biodiesel and the company then launched a 20% biofuel blend, ECO Bunkers E20.

Gasum completes SIMOPS LNG bunkering operation of PCTC “Höegh Sunlight”

Energy company Gasum on Wednesday (19 March) announced its delivery of liquified natural gas (LNG) to a car carrier during a simultaneous bunkering and cargo operation (SIMOPS) at the Port of Gothenburg, Sweden.

The company said it was the first ever LNG delivery to Höegh Sunlight at the Logent Car Terminal on 10 March 2025.

Gasum’s LNG bunker vessel Coralius made its 920th LNG delivery to Höegh Sunlight, a brand new Pure Car and Truck Carrier (PCTC), with a capacity of 9100 CEU, during a ship-to-ship (STS) bunkering operation.

The company did not specify the amount of LNG supplied to the vessel.

The delivery was a collaboration between Gasum, Glander International, Höegh Autoliners, the Port of Gothenburg and Sirius Agency.
