BV issues AiP for boxship retrofit concept combining LNG fuel conversion vessel jumboization

GTT, a technological expert in membrane containment systems, Alwena Shipping, a naval consultancy and engineering firm, and COSCO Shipping Heavy Industry (Zhoushan) Co., Ltd (CHI Zhoushan) shipyard, on Tuesday (1 March) said the trio have received an Approval in Principle (AiP) from classification society Bureau Veritas (BV) for a new concept, combining LNG retrofit and jumboization, applied to large container ships.

GTT carried out the LNG Mark III membrane tank design while its integration into the ship was designed and validated by Alwena Shipping. CHI Zhoushan shipyard validated the operational aspects of the project, including the work sequence, planning and workforce resources.

The length increase of the ship (or jumboization), combined with the LNG conversion of the propulsion and electrical generation systems enables a reduction in the operating costs of the ship, which limits the financial impact of the immobilization period required for the retrofit operation.

LNG propulsion offers ship-owners a solution to comply with the environmental regulations being adopted by the IMO by 2045. In comparison with a conventional fuel-powered container ship, the converted vessel reduces CO2 emissions by around 23% over an 83-day Europe-Asia return trip (port calls included).

The work carried out within the Joint Development Program (JDP) between GTT, Alwena Shipping and CHI Zhoushan supports the technical, operational and commercial design of the conversion and jumboization operation, while also proposing a competitive industrial plan.

The result of this joint work shows the way to contribute to decarbonize part of the container ship fleet currently in operation.

BV confirmed the conception of the retrofit, as well as the layout of the LNG Fuel Containment System and Gas Fuel Supply System supported by an auxiliary safety system in accordance with IGF Code and BV Rule NR 529. After reviewing the modifications to the vessel and the description of the associated operations, Bureau Veritas Marine & Offshore gave its AiP on the concept on 11 January 2022.

Philippe Berterottière, Chairman and CEO of GTT, said: “This retrofit and jumboization project applied to very large container vessels is part of the GTT strategy to contribute to the maritime industry decarbonisation by leveraging its technical know-how. After the successful LNG exoskeleton retrofit of the Brussel Express, GTT proposes here a model enabling to finance the conversion operation by a vessel cargo capacity increase.”

Ludovic Gérard, President of Alwena Shipping, said: “This project is remarkable in many ways: while switching to a transition fuel offering reductions in CO2, particulate and NOx emissions, this concept approved by Bureau Veritas also extends the life of the vessels converted and increases container capacity thus contributing to reducing the tension on the container transport markets.”

Gong Weibing, Vice General Manager of CHI Zhoushan, said: “We are pleased that CHI Zhoushan is able to offer solutions to upgrade vessels and reduce their environmental impact. This project is a competitive achievement as well as an important step forward on the journey towards carbon neutrality. The retrofit & jumboization will enable a safer, greener, more efficient, and more sustainable shipping business.”

Laurent Leblanc, Senior Vice President Technical & Operations at Bureau Veritas Marine & Offshore, commented: “Retrofit is part of the options to be considered by ship-owners and operators. It can be a cost-effective option. I am proud BV could support this project, which is fully aligned with our ambition to enable the industry to tackle the energy transition in a safe and efficient manner.”

Yang Ming orders six LNG dual-fuel, ammonia-ready containerships from Hanwha Ocean

Taiwanese shipping firm Yang Ming Marine Transport Corporation (Yang Ming) and South Korean shipbuilder Hanwha Ocean on Wednesday (2 September) signed a shipbuilding contract for six 13,000 TEU class LNG dual-fuel container vessels. 

The contract was signed by Dr. Chuck Tsai, Chairman of Yang Ming, and Mr. Charles Kim, CEO of Hanwha Ocean. The vessels are scheduled for delivery between 2028 and 2029. 

They will complement Yang Ming’s existing fleet of 10,000+ TEU vessels and serve as key vessels on East-West services, with deployment flexibility across trade lanes connecting Asia with the East and West Coasts of North America, South America, and the Mediterranean. 

Each of the six new vessels will have a capacity of up to 13,650 TEU and feature LNG dual-fuel propulsion and Ammonia Fuel Ready specifications.

“As Yang Ming transitions toward net-zero emissions, LNG provides a relatively mature and economically viable alternative fuel solution, capable of reducing greenhouse gas emissions by approximately 20%,” the company said. 

“At the same time, ammonia can serve as a carbon-free fuel by utilising converted LNG storage facilities, while offering relatively lower conversion costs and comparatively well-developed supply chains and infrastructure. The Ammonia Fuel Ready design will therefore provide Yang Ming with greater flexibility in responding to increasingly stringent international regulations on greenhouse gas emissions.”

In addition, the vessels will be equipped with Type B LNG fuel tanks with a design pressure of 1.0 bar to enhance the safety and efficiency of LNG operations, together with a range of energy-saving technologies, including Wind Shields, Rudder Bulbs, Pre-Swirl Stators, and Shore Power Systems. Smart ship technologies and cybersecurity protection features will also be incorporated to enhance operational efficiency, safety, and reliability while effectively reducing fuel consumption and greenhouse gas emissions.

Deliveries under Yang Ming’s next-generation fleet optimization plan commenced earlier this year. By 2030, a total of 24 new vessels are expected to enter service. 

This includes 18 LNG dual-fuel vessels—comprising five 15,500 TEU, seven 16,000 TEU, and the six 13,000 TEU vessels under this contract—alongside six 8,000 TEU methanol dual-fuel-ready ships.

LR, China’s MARIC unveil tanker concept ready for three future bunker fuels

Lloyd’s Register (LR) and the Marine Design and Research Institute of China (MARIC) on Thursday (3 September) have secured Approval in Principle (AiP) for a new 114,000 DWT product and crude oil tanker designed to accommodate future conversion to LNG, methanol or ammonia.

Announced at SMM 2026, the concept addresses one of the biggest investment challenges facing shipping today: the need to develop vessels and capabilities that can support a range of alternative fuel options and pathways as technologies, infrastructure and regulations evolve.

While LNG is already a mature fuel pathway, methanol and ammonia remain at an earlier stage of development, with questions around global fuel availability, infrastructure development, economics and long-term adoption.

The 114,000 DWT tanker concept has been designed as a product and crude oil carrier that can accommodate future conversion to LNG, methanol or ammonia as technologies, regulations and fuel supply chains mature. By incorporating conversion readiness at the design stage, the concept aims to reduce future retrofit complexity and provide owners with greater confidence when planning long-term fleet investments.

The design concept was reviewed against LR’s July 2026 class rules and regulations, including requirements relating to ships using gases and other low-flashpoint fuels, alongside relevant IACS Common Structural Rules for oil tankers. Final classification and statutory approval remain subject to full compliance with all applicable rules and regulations.

Theo Kourmpelis, Global Business Director for Tankers, Lloyd’s Register, said: “Shipowners are being asked to make major investment decisions today despite continued uncertainty around which fuels will dominate in the decades ahead. Alternative fuel solutions each offer potential pathways to compliance, but fuel infrastructure, regulation and economics continue to evolve at different speeds around the world.

“Designs that preserve flexibility will be critical in helping owners manage risk while preparing for multiple future scenarios.”

Si Nan, Marine & Offshore Marketing Department Vice Director, MARIC, said: “As the industry explores different decarbonisation pathways, shipowners need vessel designs that can adapt alongside technological and regulatory developments. This concept was developed specifically to provide greater fuel flexibility and long-term resilience, allowing owners to respond to changing market requirements without being locked into a single fuel strategy.

“Receiving Approval in Principle from Lloyd’s Register is an important milestone that validates the design concept and supports its future development.”

DNV: Alternative-fuelled vessel orders hit highest monthly level since October 2024

Latest data from classification society DNV’s Alternative Fuels Insight (AFI) platform alternative-fuelled vessel ordering was strong in August, with 52 new vessels added to the platform.

This is the highest monthly total since October 2024 and follows another active month in July, when 47 vessels were added to the database.

LNG-fuelled vessels accounted for the vast majority of August activity, with 46 orders recorded. The container segment led the way with 30 orders, while the car carrier segment contributed a further 12 LNG-fuelled vessels. In addition, four ethanol-fuelled bulk carriers and two hydrogen-powered bulk carriers were added during the month, as well as one LNG bunker vessel.

The strong summer performance marked a significant acceleration in ordering activity after a relatively slow start to the year. In total, 242 alternative-fuelled vessel orders have been placed in the first eight months of 2026, representing a 27% increase compared with the same period in 2025.

LNG remains the dominant fuel choice, accounting for 63% of all alternative-fuelled vessel orders registered so far this year. Container vessels represent the largest share of these LNG orders (59%), followed by car carriers (30%).

Jason Stefanatos, Global Decarbonization Director at DNV Maritime, said: “The past two months have been particularly strong for alternative-fuelled vessel ordering, with August recording the highest monthly total we’ve seen since October 2024. This has helped lift year-to-date orders to a level well above the same period last year.

“LNG remains the leading fuel choice, driven largely by activity in the container and car carrier segments. These sectors have been among the earliest adopters of alternative fuels, supported by predictable liner operations and increasing demand from cargo owners to reduce emissions across supply chains. 

“For many owners, LNG offers a combination of emissions reductions, fuel availability and future flexibility while the longer-term fuel landscape continues to evolve. 

“At the same time, the latest figures include orders for ethanol- and hydrogen-fuelled vessels, highlighting that owners continue to explore a range of decarbonization pathways. Different segments are making different fuel choices, but the overall level of activity demonstrates continued investment in lower-emission shipping.”
