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.”

Fratelli Cosulich Marine Energy and IINO Lines on Thursday (19 June) announced a strategic cooperation that reinforces their shared commitment to the decarbonisation of the maritime industry.

The two companies have signed a Memorandum of Understanding (MoU) to explore new business opportunities in the alternative marine fuels sector. 

“This agreement marks a significant step in the long-standing relationship between the two companies and sets the foundation for further collaboration in the areas of methanol, LNG, and ammonia bunkering,” Fratelli Cosulich said. 

Through the MoU, the parties will engage in joint initiatives, exchange market insights, and facilitate connections with potential suppliers and stakeholders in the alternative fuels space. 

“We are proud to announce the partnership with Fratelli Cosulich for initiatives in alternative marine fuels. Both companies have extensive history in the shipping industry,” said Yusuke Otani, President of IINO Lines. 

“The joint development will enable a holistic approach for building a supply chain of alternative marine fuels.”

“As we navigate the energy transition, partnerships like the one we announce today with IINO Lines are essential in shaping the future of sustainable shipping,” said Timothy Cosulich, CEO of Fratelli Cosulich Group. 

“By combining our expertise and resources, we aim to drive the adoption of cleaner marine fuels and contribute to the decarbonization of global shipping.”

Port of Nanaimo achieves milestone with first LNG bunkering operation

Port of Nanaimo on Wednesday (18 June) said the first LNG bunkering operation in the port was completed with shipowner Seaspan, marking a new milestone for the Canadian port.

Bunker vessel Seaspan Garibaldi successfully completed a ship-to-ship LNG bunkering operation at anchor to Lake Saint Anne, an LNG-powered car carrier chartered by EUKOR and managed by Eastern Pacific Shipping Limited (EPS). 

“With multiple successful LNG bunkering operations already completed in 2025 for car carriers, tankers, container ships, and cruise ships, Seaspan Energy is setting the standard for reliable LNG ship-to-ship bunkering on the West Coast of North America,” the port said in a social media post.  

“The Port of Nanaimo is supportive of the Vancouver Fraser Port Authority and Seaspan’s groundbreaking efforts to introduce cleaner fuels into the marine industry. Seaspan Energy is the first company in Canada to provide ship-to-ship LNG bunkering solutions and have three vessels working on the West Coast of North America.”

SG bunker performance May 2025

Bunker fuel sales at Singapore port inched forward by 1.1% on year in May 2025, the highest volume seen in 2025, according to Maritime and Port Authority of Singapore (MPA) data.

In total, 4.88 million metric tonnes (mt) (exact 4,878,100 mt) of various marine fuel grades were delivered at the world’s largest bunkering port in April, up from 4.83 million mt (4,826,800 mt) recorded during the similar month in 2024.

Deliveries of marine fuel oil, low sulphur fuel oil, ultra low sulphur fuel oil, marine gas oil and marine diesel oil in May (against on year) recorded respectively 1.89 million mt (+8.6% from 1.74 million mt), 2.45 million mt (-7.2% from 2.64 million mt), 1,200 mt (from zero), 1,700 mt (-88% from 14,300 mt) and zero (from zero).

SG bunker port performance May 2025

Bio-blended variants of marine fuel oil, low sulphur fuel oil, ultra low sulphur fuel oil, marine gas oil and marine diesel oil in May (against on year) recorded respectively 40,900 mt (+671.7% from 5,300 mt), 95,800 mt (+97.9% from 48,400 mt), 700 mt (from zero), zero (from zero) and zero (from 300 mt). B100 biofuel bunkers, introduced in February this year, recorded 1,900 mt of deliveries in May.

LNG and methanol sales were respectively 45,000 mt (-7.8% from 48,800) and zero (from 1,600 mt). There were no recorded sales of ammonia for the month and so far in 2025.
