A.P. Moller – Maersk has taken delivery of the Tema Mærsk, a 9,000 TEU container ship powered by WinGD’s flexible X82DF-M/E multi-fuel engine platform featuring methanol and inherent ethanol capabilities. The delivery marks the third vessel in a six-ship series, highlighting how leading liners are building ecosystem resilience and avoiding technology lock-in via dual-fuel propulsion as global alternative fuel supply chains mature.
Switzerland | June 1, 2026 – The momentum behind alternative fuel propulsion reached another critical milestone as Danish container shipping giant A.P. Moller – Maersk officially took delivery of the Tema Mærsk. The 9,000 TEU vessel is equipped with Swiss marine power company WinGD’s state-of-the-art X82DF-M/E multi-fuel engine platform, introducing advanced methanol capability and native ethanol compatibility to mid-sized container fleets.
The naming ceremony took place on May 29, 2026, at China’s Yangzijiang Shipbuilding. The high-profile industry event was attended by WinGD Chief Executive Officer Dominik Schneiter and Vice President Market Development Benny Hilström, alongside executive partners and suppliers.
The Tema Mærsk joins an expanding network of green corridor container ships, marking the third mid-sized dual-fuel vessel to enter the Maersk fleet following the recent rollouts of sister ships Tangier Mærsk and Tauranga Mærsk. The remaining three vessels in the original six-ship order are scheduled for staggered deliveries.
Technical Specifications: The X82DF-M/E Engine Architecture
The deployment of the X82DF-M/E on the Tema Mærsk, originally installed and integrated during the vessel’s hull construction phase in 2025, represents a commercial scaling up for WinGD. The move extends the engine designer’s methanol options to a large 82-centimeter bore size, a critical segment for mid-to-large container applications, pure car/truck carriers (PCTCs), and tankers.
Vessel Profile & Propulsion Parameters
| Specification Category | Vessel & Propulsion Metrics |
| Vessel Name | Tema Mærsk (IMO 1029340) |
| Capacity | 9,000 TEU |
| Vessel Dimensions | 274 meters (Length) x 46 meters (Breadth) |
| Main Engine Model | WinGD X82DF-M/E (Two-stroke, low-speed) |
| Fuel Capabilities | Green Methanol / Bio-Ethanol / Conventional Marine Fuel Oils |
The technology offers unique fuel hedging advantages. Because the engine features an inherent chemical flexibility to burn a broad spectrum of alcohol-based fuels, early adopters are shielded against regional supply bottlenecks. If green methanol supplies remain constrained or experience localized price spikes, the platform is designed to seamlessly adapt to alternative bio-alcohol options without triggering asset stranding.
Mitigating Risk in a Multi-Fuel Future
The contract traces back to March 2023, when Maersk placed a cornerstone order for WinGD’s X-DF-M dual-fuel engines to power a series of six 9,000 TEU boxships. This delivery underscores how premier liner operators are actively renewing their asset portfolios to shield global logistics chains against incoming carbon pricing mechanism penalties.
Fuel Optionality Framework
- Alcohol Pathway: Native configuration optimized for Green Methanol, with drop-in readiness for Bio-Ethanol.
- Conventional Pathway: Full operational flexibility to switch to VLSFO, ULSFO, or MGO based on market availability and compliance economics.
Building Ecosystem Resilience
WinGD’s leadership emphasized that the multi-fuel architecture is specifically designed to eliminate technology lock-in for forward-looking shipowners:
“As another methanol-capable ship joins the global fleet, we’re proud to play our part in the industry’s decarbonisation journey. Collaborating with pioneering shipowners like Maersk, we’re helping deliver the dual-fuel propulsion solutions that meet today’s real-world commercial, operational and environmental requirements while being ready for the net-zero world of tomorrow. With inherent flexibility to accommodate multiple alcohol fuels, our technology ensures that early adopters are not locked into a single pathway as the fuel landscape develops.” said, Dominik Schneiter, CEO, WinGD Ltd.
Maersk’s technology leadership pointed to the broader industry dynamics, noting that engine delivery is only one part of the wider fuel transformation puzzle:
“Developing future-proof engine technology is a critical step in building the flexibility and reliability which global supply chains depend on. At the same time, the energy transition of the shipping industry is a complex challenge that requires close collaboration across the entire ecosystem – from shipowners and regulators to fuel producers, infrastructure providers and engine manufacturers. We truly value our collaboration with WinGD in delivering a robust, energy efficient engine design for our series of 9,000 TEU dual-fuel vessels.” said, Ole Graa Jakobsen, Head of Fleet Technology, A.P. Moller – Maersk
The Bunker Brief Insight
The delivery of the Tema Mærsk highlights a major strategic development in current fleet deployment tactics. While mega-boxships exceeding 18,000 TEU face physical deployment limits to select tier-one routes, these high-efficiency, 9,000 TEU “mid-sized” multi-fuel workhorses offer massive operational versatility.
For the bunker market, this signifies that demand for alternative bunkering infrastructure is moving rapidly outside of just major transshipment mega-hubs. As these highly flexible vessels route across diverse global trades, secondary ports must accelerate their green methanol and alcohol-handling capabilities to service an increasingly diverse, dual-fuel fleet.
