The Maritime Energy & Sustainable Development Centre of Excellence (MESD) on Saturday (8 April) said its researchers have published an article on ammonia bunkering and the impact of key operational parameters has on the dispersion of ammonia.

The article titled Accidental release of ammonia during ammonia bunkering: Dispersion behaviour under the influence of operational and weather conditions in Singapore was published in the Journal of Hazardous Materials.

The centre’s researchers are Research Associate Clara Kay Leng NG, Research Lead Dr Liu Ming, Centre Director Professor Jasmine Lam, and Research Associate Yang Mengyao. 

The safety study simulates the impact of key operational parameters on ammonia dispersion and its consequences. 

The findings suggest that refrigerated storage of ammonia is most effective in reducing ammonia bunkering operational risks, and the severity of the consequences increases significantly with a release height of more than 5m. 

“In addition to avoiding the vertical release of ammonia, reducing the release duration and transfer flow rate can significantly reduce severity. Based on the scenario used in this study, the ammonia cloud disperses over a longer distance over water due to the high vaporisation rate driven by the large amount of heat generated from the dissolution of ammonia in seawater, and the dispersion of ammonia spreads over a larger area during the day than at night,” MESD said. 

“These findings provide valuable insights into the development of effective operational and mitigation control measures for ammonia bunkering operations, ultimately promoting safer and more sustainable practices in the maritime industry.”

Bunker Fuel

SMW 2024: Singapore is preparing port for multi-fuel future, says Transport Minister.

‘Our industry has brought in new bunker tankers capable of bunkering higher blends of biofuel and methanol, paving the way for greater emissions reduction for vessels,’ says Chee Hong Tat.

SMW 2024: Singapore is preparing port for a multi-fuel future, says Transport Minister.

Singapore has moved decisively to ensure energy and fuel resilience as international shipping looks to alternative fuels to meet global decarbonisation targets, said Singapore’s Minister for Transport Mr Chee Hong Tat on Monday (15 April).

In his speech at the Singapore Maritime Week (SMW) 2024 opening ceremony, he said Singapore is preparing its port for a multi-fuel future.

“Our industry has brought in new bunker tankers capable of bunkering higher blends of biofuel and methanol, paving the way for greater emissions reduction for vessels,” he said.

“MPA has also issued Expressions of Interest (EOI) for the alternative fuels ammonia and methanol over this past year.

“For our ammonia EOI, we have shortlisted six consortiums, and are studying their comprehensive proposals for the supply of ammonia for bunkering and power generation in Singapore.”

Chee added reliability and resilience also mean that Singapore upholds the highest standards for safety, efficiency, and quality. 

“Enterprise Singapore, through the Singapore Standards Council, has been working closely with industry partners to introduce national standards to support the digitalisation of bunkering supply chain documentation, as well as on methanol and ammonia bunkering.”

“As a major maritime and bunkering hub, Singapore is committed to continue serving as a trusted node for international shipping.”

Chee said this when elaborating on Singapore’s focus to grow the republic as a hub for reliable and resilient maritime operations, one of three important areas the republic will prioritise on growing its maritime sector. 

The other two areas are to grow Maritime Singapore as a hub for maritime innovation and as a hub for maritime talent development.

“Looking ahead, we expect some turbulence along the way, but we are confident that the global maritime industry will continue to grow,” Chee said.

“And Singapore as a hub port and International Maritime Centre can benefit from this growth and the opportunities it brings, including in emerging areas like digitalisation and decarbonisation.”

However, Chee warned Singapore shouldn’t take its success for granted and to continue improving productivity and competitiveness while staying relevant to changing requirements to be able to meet the needs of local and international stakeholders. 

“But we must not rest on our laurels, or make the mistake of thinking that these positive outcomes will happen on auto-pilot. A rising tide can indeed lift all boats, but the boat and its crew can only benefit if they are well-prepared when the water level rises,” he said.

Banle Energy arranges B24 bunkering services for “YM Utility” in Yantian

Banle Energy International Limited, a subsidiary of CBL International Limited, on Monday (15 April) announced the arrangement of B24 biofuel bunkering services for Yang Ming's vessel YM Utility at a port in Yantian, Shenzhen on 14 April.

“By providing Yang Ming with our B24 biofuel bunkering services, this transaction supports the first B24 biofuel supply in Shenzhen and Yang Ming's inaugural B24 biofuel bunkering supply in China,” the firm in a social media post. 

“As a company actively promoting the use of biofuels, we are making a significant contribution to the International Maritime Organization's (IMO) goal of reducing greenhouse gas emissions (GHG) from international shipping.”

“The B24 biofuel blend, as indicated by a study, is projected to reduce approximately 20% of Greenhouse Gas (GHG) emissions when compared with conventional fuel oil.”

As the firm focuses on expanding its operations in Europe, the firm added it will continue to forge strategic partnerships and explore new opportunities to provide efficient and reliable solutions.

Singapore bunker tanker to be equipped with MAN ES DF gensets

Singapore bunker tanker to be equipped with MAN ES DF gensets

MAN Energy Solutions (MAN ES) on Monday (15 April) said it has received an order for three MAN 6L21/31DF-M (Dual Fuel-Methanol) GenSets capable of running on methanol in connection with the construction of a 7,990 dwt IMO Type II chemical bunker tanker.

The newbuild will operate at the port of Singapore under charter to deliver marine fuels. The port itself is reported as laying plans for the steady supply of methanol from 2025 onwards in order to meet future, anticipated bunkering requirements for methanol-fuelled vessels. 

The dual-fuel engines will form part of a diesel-electric propulsion system on board the vessel with electrical motors driving twin fixed-pitch propellers via gearboxes; an onboard battery-storage system will optimise the use of the dual-fuelled generators. 

MAN Energy Solutions’ licensee, CMP – an engine-manufacturing division of Chinese State Shipbuilding Corporation (CSSC) – will build the engines in China and the vessel is scheduled for delivery during Q4, 2025.

Bjarne Foldager – Country Manager, Denmark – MAN Energy Solutions, said: “Seeing our trusted MAN L21/31 GenSets go into these ships as a methanol-fuelled version shows that maritime decarbonisation is a prominent consideration for shipowners in all vessel segments and sizes.”

“It also clearly illustrates, regardless of the market one serves as shipowner, that our broad, dual-fuel portfolio enables everyone to take part in the green transition.”

Thomas S. Hansen – Head of Sales and Promotion – MAN Energy Solutions, said: “The MAN L21/31 engine is well-established in the market having racked up some 2,750 sales.”

“The reliability of its cost-effective, port fuel-injection concept now prominently positions the 21/31DF-M as the preferred, medium-speed, small-bore engine for GenSet and diesel-electric propulsion solutions, while also meeting market demands to balance both CAPEX and OPEX.”

“With the shipping market currently experiencing an increased interest in methanol as marine fuel, and orders for methanol-fuelled ships steadily growing as part of many companies’ decarbonisation strategy, we feel that the introduction of this dual-fuel engine is timely.”
