An industry coalition SEA-LNG analysis, published on Tuesday (17 December) showed that LNG dual-fuelled vessels provide the lowest compliance cost for meeting EU and IMO decarbonisation regulations.

Using Z-Joule’s POOL.FM, SEA-LNG has undertaken analysis based on a modelled mid-sized, 14,000 TEU container vessel. This analysis is in the form of both a single vessel and also an eight-vessel fleet operating the Rotterdam – Singapore trade route over the period 2025 to 2040.

The analysis focuses on the LNG, methanol, and ammonia fuel pathways and compares their compliance costs against the default of using VLSFO (very low sulphur fuel oil). The analysis uses the specifications for main and auxiliary engines published by the main marine engine manufacturers MAN ES, Wärtsilä and WinDG.

The study indicates that LNG, methanol, and ammonia dual-fuel engine technologies can reduce compliance costs compared with VLSFO, with LNG dual-fuel vessels providing a significantly lower cost compliance solution. The basis for this is that the LNG pathway offers immediate greenhouse gas reductions now and in the future compared with the other fuel choices. The use of LNG also dramatically reduces SOx, NOx and Particulate Matter (PM), thereby avoiding the use of relatively expensive MGO (marine gas oil) for ECA (Emission Control Area) compliance.

In terms of fleet operations, for an eight-vessel fleet with two alternatively fuelled “balancing vessels,” the overall cost of compliance with LNG will be between USD 5 million and USD17 million per annum lower than other alternative fuels such as methanol and ammonia. Further, as FuelEU Maritime is implemented from 2025 onwards, fleet operators using ammonia and methanol dual-fuel vessels are likely to need significant quantities of expensive green fuels in an effort to avoid very high penalty charges.

Steve Esau, Chief Operating Officer at SEA-LNG, said, “It’s our mission to provide objective data and analysis to support owners and operators in decision-making at this critical juncture for shipping.”

“As greenhouse gas emissions become subject to increasingly stringent regulation, the industry needs cost-effective solutions to meet its decarbonisation goals. Today, this study clearly illustrates that the LNG pathway is a cost-effective way to meet regulatory compliance targets now and in the future.”

Fernando Alvarez, Founder of Z-Joule, said: “Z-Joule’s software provides the industry with a robust platform to explore and optimise their decarbonisation journey.”

”POOL.FM is a fuel-agnostic model which utilises an advanced optimisation algorithm to determine the optimal fuel mix, pooling strategy, and target speed for each vessel in a fleet (or vessel pool).”

“The regulations currently modelled include CII, ECAs, EU ETS, FuelEU Maritime and Onshore Power Supply (OPS) mandates. Functionality to model possible IMO Market Based Measures (MBM)s is already in place and will be refined as more details about the forthcoming regulations emerge.”

Singapore-based ONE celebrates maiden voyage of methanol-and-ammonia ready boxship

Singapore-based container shipping company Ocean Network Express (ONE) on Thursday (3 July) said it celebrated the maiden voyage of containership ONE Solidarity as the ship made its first-ever arrival in Shekou, China.

“As one of our S-series methanol and ammonia ready container vessels, ONE Solidarity is another demonstration of ONE’s commitment to sustainable shipping,” the company said in a social media post.

Following the successful deployment of ONE Singapore and its sister vessels, ONE Solidarity will be deployed on the Mediterranean Pacific South 2 (MS2) service.

“Her deployment will boost our service capacity, ensuring faster, more reliable, and highly efficient shipping offerings across key global trade lanes,” the company added.

“Lucia Cosulich” enters final preparation ahead of bunkering operations

Fratelli Cosulich Marine Energy on Thursday (2 July) celebrated the delivery of Lucia Cosulich at Taizhou Maple Leaf Shipyard in China.

The vessel is the second of four sister methanol-ready IMO II bunker tankers developed within the Group’s fleet expansion programme and follows the launching ceremony held on 2 May 2026.

Designed to support the Group’s bunkering operations and future fuel requirements, Lucia Cosulich is part of the new generation of vessels developed by Fratelli Cosulich Marine Energy to combine operational reliability, safety and fuel flexibility.

Lucia Cosulich will now enter the final preparation phase ahead of its next operational steps, further strengthening the Group’s ability to provide reliable bunkering solutions.

“We wish Lucia Cosulich and her crew fair winds on the next stage of her journey,” the company said.

DNV: Alternative-fuelled vessel orders down 11.6% in H1 2026

In total, 137 alternative-fuelled vessels were ordered in the first half of 2026 compared to 155 in the same period in 2025.

DNV: Alternative-fuelled vessel orders down 11.6% in H1 2026

Latest data from classification society DNV’s Alternative Fuels Insight (AFI) platform showed a total of 15 new orders for alternative-fuelled vessels were placed in June 2026.

This consisted of 10 orders for LNG-fuelled vessels, nine of which were car carriers and one a CO2 carrier. The remaining five orders were for LPG/ethane carriers.

Two LNG-bunker vessels were also ordered in June, bringing the total in this segment to seven so far in 2026.

In total, 137 alternative-fuelled vessels were ordered in the first half of 2026, down 11.6% from 155 in the same period in 2025.

Over half of these (73) were for LNG-fuelled vessels, with most coming from the container (42) and car carrier (21) segments. LPG/ethane carriers were also prominent, with 55 new orders, a significant uptick compared to the first half of 2025 (15). The remaining orders were for vessels fuelled by methanol (2), ethanol (2), ammonia (4), and hydrogen (1).

Deliveries in the first half of the year point to continued uptake of alternative-fuelled tonnage across several segments, with 61 LNG-fuelled vessels and 38 methanol-fuelled vessels delivered so far in 2026.

More recently, Exmar took delivery of what it described as the first oceangoing dual-fuel ammonia vessel, marking a step beyond earlier ammonia-fuelled deliveries, which have largely been associated with pilot or demonstration projects rather than commercial deployment.

Jason Stefanatos, Global Decarbonization Director at DNV Maritime, said: “What we can take away from the first half of 2026, in terms of the alternative-fuels orderbook, is that we have a market progressing at different speeds depending on segment economics, fuel availability, and the regulatory landscape. Shipowners and other stakeholders are pursuing different pathways based on their individual priorities and requirements.

“LNG remains the leading near-term fuel option, with order activity continuing to be led by containers and car carriers. LPG and ethane carriers have also accounted for a significant share of activity in the first half of the year, while developments in areas such as ammonia and ethanol show that multiple pathways continue to be explored.”
