Classification society Bureau Veritas (BV) on Monday (18 September) announced a Joint Development Project (JDP) with shipbuilder Hanwha Ocean on the structural assessment of independent LNG fuel tanks for ultra large container ships (ULCs). 

The JDP agreement was signed by Joong-Kyu Kang, Head of R&D Institute of Hanwha Ocean Co., Ltd and Drago Pinteric, Country Chief Executive Korea of Marine & Offshore at Bureau Veritas, at a ceremony on 6 September at Gastech 2023 in Singapore. 

The project aims to enhance the design process of independent LNG fuel tanks and accelerate the development of new solutions for the structural assessment of those systems.

Today many vessels are equipped with independent tanks, either for the purpose of LNG/LPG transportation or for the use of LNG/LPG as a fuel. The particularity of these independent tanks is that they are not rigidly connected to the hull structure but are instead held by an important number of dedicated supports, which must be designed with consideration of non-linear structural response during operations, including loss of contact and sliding.

Accurately solving these contact nonlinearities usually requires large computational time, and the method is very sensitive to convergence parameters. Recently, Bureau Veritas developed a new methodology to assess contact behaviour nonlinearities. 

The method was validated by comparison with simulations, and it was demonstrated that the CPU (central processing unit) time is significantly lower, while maintaining the same levels of accuracy. The proposed solution, which has been implemented in the Bureau Veritas hydro-structure interaction suite Homer, allows for the fully consistent structural analysis of vessels equipped with independent tanks.

Joong-Kyu Kang, Head of R&D Institute of Hanwha Ocean, said: “Through this JDP with Bureau Veritas, it is expected that structural analysis technology will be further advanced to improve the performance of independent tanks and develop differentiated products for the application of future projects.”

Alexander Gregg-Smith, Senior Vice President - North Asia Zone, Bureau Veritas M&O, said: “Bureau Veritas M&OWe are pleased to cooperate with Hanwha Ocean on the structural assessment of independent LNG fuel tanks, which will support technology development for the future application of innovative solutions while also ensuring the safety of shipping. We hope that this project will strengthen the collaboration and relationship between Hanwha Ocean and Bureau Veritas for the future development of more sustainable shipping solutions and technologies.”

SIBCON 2024: SGMF releases methanol and ammonia bunkering guidelines

SGMF on Wednesday (9 October) announced the release of the Bunkering Guidelines for Ammonia and Bunkering Guidelines for Methanol, as well as the Emergency Response Guide for Ammonia.

During the 23rd Singapore International Bunkering Conference (SIBCON), SGMF also revealed its new brand reflecting the organisation’s current activities in the four key marine fuels for the future: LNG, methanol, ammonia and hydrogen.

SGMF is a membership-based organisation leading safe maritime decarbonisation with members across the full value chain of marine fuels, including suppliers, operators, owners, equipment manufacturers, class societies, port authorities, individuals and training organisations.

While the search for the perfect alternative fuel continues, SGMF said methanol and ammonia are two of the fuels that the global merchant fleet has identified and is looking to implement, emphasising the importance of these guidelines. 

Methanol – With the first vessels already running on methanol, and many more on order, methanol is ahead of the curve in terms of adoption. It has also overtaken regulation, meaning that these early adopters are having to put forward safety solutions that have not yet been documented, and bunker suppliers using existing chemical carriers are trying to second guess what conversion and equipment may be needed to make their vessels physically compatible with the ships being produced. These methanol bunkering guidelines have been published as a first draft to highlight the key safety factors that need to be considered when designing and bunkering a vessel of any type with methanol. 

Ammonia – Despite ammonia (NH3) not yet being commercially available as a marine fuel, this bunkering document provides guidance to all the stakeholders currently investigating and developing the bunkering of ships with fully refrigerated (-33°C) ammonia.

A range of potential hazards are expected with bunkering ammonia and to date there is very limited experience, with only one series of bunkering trials conducted as at March 2024. 

As a result, Bunkering Guidelines for Ammonia draws primarily on the current experience of LNG bunkering, the wider ammonia marine transport industry and the shoreside ammonia production and transport industry experience. 

“The overall aim of these guidelines is therefore to ensure that ammonia-fuelled ships are bunkered safely, reliably, efficiently and in an environmentally responsible way, targeting the avoidance of operational or fugitive emissions of ammonia,” SGMF added. 

These publications have been compiled with extensive input from the SGMF membership, as well as with collaborative support from the Global Centre for Maritime Decarbonisation (GCMD) and the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping (MMMCZCS).

Note: The bunkering guidelines are available in the shop on SGMF portal and the Emergency Response Guide for Ammonia can be downloaded through its free resources section.

Bunker One to launch physical LNG bunker fuel supply in January 2025

Bunker Holding’s physical supply division, Bunker One, on Wednesday (9 October) said it is set to launch LNG bunker supply in northwestern Europe as of January 2025.

Building on its existing successful activities supplying alternative fuels, Bunker One is expanding its current fuels portfolio by adding physical LNG and mass balanced LBM (Liquefied Biomethane). Bunker One expects to be ready to commence first physical LNG deliveries in January 2025.

Bunker One has established a new entity, Bunker One LNG BV, which will manage the physical LNG fuel portfolio including last-mile delivery and will be headed by Managing Director, Michael Behmerburg.

Peter Zachariassen, CEO of Bunker One, said: “We are extremely pleased to be welcoming Michael Behmerburg to steer our Bunker One LNG entity. Michael brings a wealth of experience that is important for us to navigate properly in the upcoming transition.”

Bunker One LNG BV has chartered the 10,000 cbm LNG Bunker Vessel, Coral Fraseri.

Michael Behmerburg, said: “We are working hand in hand with the vessel’s owner Anthony Veder to bring the vessel into operation. The vessel will undergo a regular class renewal at the end of 2024, during which several modifications will be carried out to enhance her capabilities as an LNG bunker vessel.”

The purpose of the modifications is to prepare the vessel for best-in-class service to the majority of seagoing vessels, including tankers, container ships, and car carriers. Bunker One LNG BV is currently in the process of securing bunker permits which will cover key ports in Northwest Europe.

Valerie Ahrens, Senior Director of New Fuels and Carbon Markets at Bunker Holding, said: “We are very excited about this move to include physical supply of LNG and LBM as part of Bunker Holding’s fuel offering, which builds on our successful activities supplying LNG through third parties.”

“Fossil LNG can offer up to 23% in greenhouse gas (GHG) reductions compared to conventional fuels and accompanies shipping’s transition to a multi-fuel future. Hence, we regard LNG as a stepping stone to bio-LNG and e-LNG, which will help the industry achieve the mid-century decarbonisation targets set by the IMO.”

Seaspan Energy takes delivery of first LNG bunkering vessel “Seaspan Garibaldi”

Seaspan Energy on Monday (7 October) said it took delivery of its first LNG bunkering vessel, the Seaspan Garibaldi and is currently sailing to Vancouver.

Manifold Times previously reported that the vessel is the first of three 7,600m3 LNG bunkering vessels and it is named after Mount Garibaldi, or “Nch'ḵay̓”.

The Garibaldi will take first cargo and finalise commissioning in Vancouver before its first ship-to-ship bunkering in Long Beach, where Seaspan will provide Simultaneous Operations to bunker a series of vessels.

Following its first bunkering, the Seaspan Garibaldi will continue to provide low-carbon solutions to vessels on the West Coast of North America and will soon be joined by Seaspan Energy’s second LNG bunkering vessel, the Seaspan Lions (Ch’ich’iyúy Elxwíkn).

The Seaspan Garibaldi is 112.8 metres in length, 18.6 metres in width, 5 metres in draft, with a design speed of 13 knots.

CIMC Sinopacific Offshore & Engineering (CIMC SOE), a small-scale gas carrier shipyard in the world, was appointed to build all three LNG bunkering vessels.
