Classification society Bureau Veritas on Monday (8 May) said it delivered an Approval in Principle (AiP) to GTT and Shanghai Waigaoqiao Shipyard (SWS) for the design of a Liquefied Natural Gas (LNG) dual-fuel Very Large Crude Carrier (VLCC).

This approval is part of a Joint Development Project (JDP) initiated in May 2022, and was successfully carried out by Shanghai Waigaiqiao Shipyard (SWS) and Bureau Veritas (BV).

The greater operational flexibility offered by this new 10,000 m3 capacity fuel tank concept, enables owners and charterers to conduct round trip voyages between the Middle East, Asia, and Europe with just one LNG bunkering operation.

The fuel tank is located below the main deck to avoid exposure to bad weather and the risk of piracy, while lowering the centre of gravity of the propulsion systems. It features Mark III membrane containment technology, developed by GTT.

In addition to its operational benefits, the new LNG dual-fuel VLCC concept complies with key environmental requirements. Its Energy Efficiency Design Index (EEDI) is more 37% under the baseline, its Nitrogen Oxides (NOX) emissions meet the IMO’s Tier III requirements, and its Carbon Intensity Index (CII) is projected to be rated A by 2030.

Adnan Ezzarhouni, General Manager of GTT China, said: “We are delighted to be granted with this AiP by Bureau Veritas with whom GTT has had a close partnership for many years. Following our successful references in LNG-fuelled container and cruise vessels, we are pleased to offer this fit-for-purpose membrane tank solution to the LNG-fuelled tanker market.”

Alex Greg-Smith, Senior Vice President Chief Executive, Marine & Offshore North Asia and China, Bureau Veritas, said: “Our knowledge of LNG as fuel was mobilised from the design phase for this dual fuel VLCC. From plan approval to classing the vessel – Bureau Veritas experts played a key role in ensuring this sophisticated tanker can take to the seas safely. Dual fuel carriers open a window into what the future of the maritime energy transition will look like. A new generation of VLCCs will contribute both to maritime decarbonization as a whole and to the reduction of scope three emissions in countless other sectors.”

Methanol marine fuels consultancy GREENMARINE and Vertoro, a Maersk-backed Dutch start-up focused on developing liquid lignin technology which can be used as a bunker fuel, has signed an agreement to jointly accelerate the market validation and commercial roll-out of lignin-alcohol as sustainable marine fuels.

“We at GREENMARINE Group are excited to join forces with Vertoro to bring their revolutionary lignin alcohol blend fuel to market,” said Fredrik Stubner, founder and CEO of GREENMARINE Group.

“This breakthrough technology redefines sustainable maritime fuels, delivering environmental benefits and cost efficiencies, paving the way for a greener, more competitive shipping industry.”

Dr. Michael Boot Boot, co-founder & co-CEO Vertoro, replied, “GREENMARINE Group has an excellent track record as a match maker for green fuel producers with engine manufacturers and shipping companies, opening many doors for us on both the fuel validation and offtake side.”

Vertoro, founded in 2017, produces liquid lignin exclusively from sustainably sourced forestry and agricultural residues by means of a patented thermochemical process. Like fossil oil, liquid lignin can be used as a platform for fuel, chemical and material applications.

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.
