Technology group Wärtsilä, in cooperation with Silverstream Technologies, on Thursday (7 October) said it will install Silverstream’s proprietary air lubrication system on a trial basis on a large container vessel owned by A.P. Moller Maersk.

The trial will examine possible improvements to the ship’s overall efficiency, focusing on the reduction of fuel consumption and associated emission levels.

The programme will have a special emphasis on the potential application of the System for methanol-fuelled Maersk vessels. The ultimate aim of all three companies is to support efforts to decarbonise shipping operations. The order was placed by Maersk in May 2021.

Silverstream’s Air Lubrication System creates a carpet of microbubbles that coat the entire flat bottom of the vessel. This carpet effectively reduces frictional resistance between the hull and the water. The technology works in all maritime conditions, is not weather dependent, and does not constrain or negatively impact the normal operational profile of the vessel.

“We are delighted that A.P. Moller – Maersk is backing our market leading technology, which is proven to significantly improve operational efficiency and reduce associated greenhouse gas emissions. We also wish to thank Wärtsilä for their collaboration in the delivery of this integrated solution,” says Noah Silberschmidt, Founder & CEO, Silverstream Technologies.

“Everything that we do today inevitably sets the future for coming generations, so we need to act in a positive way to ensure that decarbonising vessel propulsion is an effective priority for the industry. This is a view that is shared by Maersk, a company with whom we have worked closely for many years. Silverstream’s Air Lubrication System is an important stepping stone along this path,” says Bernd Bertram, Vice President, Propulsion, Wärtsilä Marine Power.

The Wärtsilä / Silverstream equipment will be delivered during the second quarter of 2022.

Wärtsilä is an authorised sales and service partner for the System, which is fully integrated within the company’s propulsion portfolio. For newbuild vessels, air lubrication can notably improve compliance with the Energy Efficiency Design Index (EEDI). The System has been proven to reduce fuel burn and associated emissions by five to ten percent, depending on vessel type.

President MT

The 50th vessel constructed by local boat builder Pinnacle Marine (Singapore) Pte Ltd, namely President 100, is starting 1,000 hours of real-time research trials in collaboration with several parties from Wednesday (9 July) onwards, it says.

Powered by B100 biodiesel, the newbuilding operated by Prestige Ocean Pte Ltd will capture data on bunker fuel emissions, marine fuel behaviour, and performance.

It will be participating in trials with Maritime Energy & Sustainable Development Centre of Excellence (MESD), Weichai Singapore, China Classification Society, Pacific International Lines (PTE) Ltd, Abo Shoten, Ltd. / 株式会社安保商店 , Abo Singapore, Wilmar International, Gulf Marine, Amspec Testing & Services, and AYK Engineering and Consulting.

The President 100, Pinnacle Marine’s first full biodiesel utility boat, was launched on Tuesday in the presence of over 100 guests.

“Our latest vessel, President 100, merges legacy and future. Named after our first aluminium boat (“President”) and inspired by B100 biodiesel, it leads the charge for our next 50 vessels — many of which will embrace green technology,” stated Pinnacle Marine in a LinkedIn post.

“The launch was amazing, with strong turnout from across the maritime sector — authorities, shipowners, operators, agencies, chandlers, researchers, offshore engineers, and petrochemical suppliers.”

It added: “We’re excited to see how it paves the way for wider adoption of B100 biodiesel — a cleaner, sustainable path for Singapore’s harbour craft sector.”

BHP ammonia DF charters

Global resources company BHP on Wednesday (2 July) signed contracts with COSCO Shipping Bulk Co., Ltd., a subsidiary of COSCO shipping Group (COSCO Shipping) for the charter of two ammonia dual-fuelled Newcastlemax bulk carriers.

The new vessels to be built under this arrangement will be two of only a handful of vessels in the world capable of using ammonia as a bunker fuel.

The two vessels, expected to be delivered from 2028, will primarily transport iron ore from Western Australia to Northeast Asia.

When run on lower or low to zero greenhouse gas (GHG) emissions ammonia, these vessels will be capable of reducing GHG emissions by at least 50% and up to 95% on a per voyage basis compared to a conventionally fuelled voyage.

The five-year time charter contracts are expected to contribute towards a reduction in the GHG emissions intensity of BHP chartered shipping.

BHP continues to work with the maritime industry to develop an ammonia bunkering plan – the process of fuelling ships with ammonia – for the two vessels when they are delivered from 2028.

Sourcing lower and low to zero GHG emissions ammonia is subject to an ongoing tender process.

Everllence, formerly known as MAN Energy Solutions, on Tuesday (8 July) celebrated the order of its 1,000th ME-GI engine that can run on either heavy fuel oil or liquefied natural gas (LNG) as a bunker fuel.

The engine, a 7G95ME-GI type, is bound for a Hapag-Lloyd container vessel currently under construction at Jiangsu New Yangzi Shipbuilding Co., Ltd. where it is designated as hull #1721.

Rolf Habben Jansen, CEO of Hapag-Lloyd, said: “We are proud to mark this milestone with our partner, Everllence. The order for the 1,000th ME-GI engine reflects our commitment to decarbonising global supply chains. Dual-fuel technologies like the ME-GI are a key step on our journey to a low-emission fleet and support our ambition to drive change across the industry.”

Dr Uwe Lauber, CEO of Everllence, added: “Considering that the strongest interest in the ME-GI engine has come from the container segment, it is fitting that this significant milestone should be reached with an order from such a prestigious container player as Hapag-Lloyd. On the path to net-zero, the marine industry needs pioneers and Hapag-Lloyd is leading the way by example.”

“2025 has seen a large increase in ME-GI orders as methane makes for an excellent transition fuel on the way to decarbonising shipping. The ME-GI’s market-leading efficiency and technological maturity – as well as lowest methane slip – have confirmed its status as the marine industry’s default, dual-fuel, methane-fuelled engine.”
