The Singapore Chemical Industry Council (SCIC) and Standards Development Organisation (SDO) on Wednesday (26 March) organised a sharing session for Singapore TR 129 and ISO 6583, learned Manifold Times.

Captain Rahul Choudhuri, Chair, TC for Bunkering (Ambient Liquid Fuels), took the opportunity to share how national and international standards support the bunker supply chain, and presented new standard and technical references to delegates at the event.

Specification for digital bunkering supply chain documentation (SS 709)
This new standard provides specifications and requirements for the main types of digital documents utilised and exchanged within bunkering supply chains, such as eBDN, aligning with established business practices and bunkering standards.

Technical Reference on Methanol Bunkering, TR 129:2025
Developed by the Maritime and Port Authority of Singapore (MPA) and Enterprise Singapore in collaboration with the SCIC, TR129 provides guidelines for custody transfer requirements, operational and safety protocols for methanol delivery, and crew training competencies.

Captain Choudhuri, who is also President, Strategic Partnerships at VPS, further shared the Technical Reference on Ammonia Bunkering (4 parts series) is expected to publish later in 2025.

“These standards will span areas including custody transfer requirements, operational and safety requirements for the delivery of the fuels from a bunker tanker to receiving vessels, as well as crew training and competencies,” he said.

Captain Choudhuri also provided an update on the ongoing revision of WA 2:2022 Specification for marine biofuel. He noted WA 2 will be upgraded to a Technical Reference by the second quarter of this year (Q2 2025).

Captain K.K. Mukherjee, Convenor of WG on Methanol Bunkering, provided an overview of TR 129 by highlighting on the importance of proper bunkering procedures for ship-to-ship, shore-to-ship, and truck-to-ship methanol bunkering operations.

He stated that a new maritime energy training facility will be established in Singapore by 2026 to equip international maritime workers with skills to handle clean marine fuels such as methanol.

Meanwhile, an MPA-approved training course for the handling of methanol as a fuel, conducted by the Singapore Maritime Academy (SMA) was launched in April 2024 and covers the operational and safety aspects of methanol bunkering operations.

Captain Mukherjee further pointed out Singapore has been actively participating in the development of ISO bunkering standards related to methanol including:

  • ISO/TC 28/SC 4/WG 18 Specifications of alternative fuels for marine applications
  • ISO/TC 8/SC 25/WG 1 Maritime GHG reduction – Alternative Fuels
  • ISO 6583 Specification of methanol as a fuel for marine applications
  • ISO/CD 22120 – Ships and marine technology – Specification for bunkering of methanol fueled vessels

Dr Liu Ming, Singapore expert, ISO/TC 28/SC 4/WG 18, spoke on the general requirements and specifications for ISO 6583 Methanol as a fuel for marine applications.

He informed most of the methanol produced today meets International Methanol Producers and Consumers Association (IMPCA) reference specifications. However, even though one set of specification is provided, not all specs are relevant when used as marine fuel and other properties to be considered when used as marine fuel.

Dr Liu also highlighted methanol marine fuel is separated into three grades:

  • grade A: MMA: lists the characteristics considered applicable when using methanol as a marine fuel with additional requirements in respect of lubricity and particle count
  • grade B: MMB lists the characteristics considered applicable when using methanol as a marine fuel
  • grade C: MMC provides for wider tolerances on some of the characteristics as compared to MMB.

Other speakers who gave presentations at the Sailing towards sustainability – New standards for marine alternative fuels event include:

  • Vibin Chandrabose, WG member, Director, Projects, Global Centre for Maritime Decarbonisation
  • Partha Das, WG Member, Global Technical Manager Lloyd’s Register (FOBAS)
  • Kelvin Kang, WG Member, General Manager, Stellar Shipmanagement Services Pte Ltd, Global Energy International Ltd
  • Capt Mohd Salleh Ahmad Sarwan, Senior Lecturer & Senior Specialist, Singapore Maritime Academy, Singapore Polytechnic

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.”
