Everllence and Hudong‑Zhonghua sign engineering design deal for 180,000 m³ hybrid‑electric

Design agreement formalised

Everllence and Hudong‑Zhonghua Shipbuilding (Group) Co., Ltd. concluded an Engineering Design Agreement on 5 June 2026, as confirmed in a joint statement released later that month. The contract commits the two parties to jointly develop a new LNG carrier of approximately 180,000 cubic metres deadweight capacity equipped with Everllence’s DFE+ (Dual‑Fuel, Electric+) propulsion system.

The partnership builds on an existing collaboration that has already delivered ten conventional dual‑fuel diesel‑electric (DFDE) vessels. Those earlier projects demonstrated the feasibility of integrating four‑stroke engines with electric drive modules in large LNG carriers.

Technical concept – hybrid‑electric powertrain

Everllence describes the DFE+ system as a “dual‑fuel hybrid‑electric propulsion” architecture that combines a marine diesel engine capable of running on both fuel oil and liquefied natural gas with an electric drive motor powered by onboard generators. The design is intended to improve overall thermal efficiency while reducing CO₂, NOₓ and SOₓ emissions.

Dominik Thoma, Global Manager LNG Cargo at Everllence, explained that “individual technology providers can only achieve marginal efficiency improvements” and that a tighter integration between shipyards and engine manufacturers is required for “bigger gains”. This view aligns with the broader industry push towards hybridisation as a stepping‑stone to full electrification or alternative fuels.

Song Wei, Chief Technical Engineer of Hudong‑Zhonghua, added that decarbonisation represents an “obvious development trend” and highlighted the uncertainty ship owners face in meeting the IMO’s 2030 and 2050 carbon‑intensity targets. He described the hybrid solution as a way to provide more options for operators seeking near‑term emissions reductions.

Regulatory backdrop

The International Maritime Organisation (IMO) has introduced increasingly stringent Carbon Intensity Indicator (CII) regulations, obliging ship owners to demonstrate progressive improvements in energy efficiency. The new carrier’s hybrid system is explicitly aimed at helping operators comply with these standards while maintaining commercial viability.

Hellenic Shipping News noted that the joint effort “sees the potential to enable and promote more environmentally friendly and efficient LNG shipping, especially in light of ever‑stricter IMO CII emission requirements”. The agency’s commentary underscores the market pressure on newbuild programmes to deliver measurable emissions cuts.

Commercial implications and project timeline

The agreement was publicly announced on 17 August 2026 by Everllence, indicating that detailed design work is already underway. While a delivery date has not been disclosed, similar large‑scale LNG carriers typically require three to four years from concept approval to sea trial.

Container News reported that the deal “builds on a prior collaboration” and positions both firms as market leaders: Hudong‑Zhonghua as a leading Chinese LNG‑carrier builder and Everllence (formerly MAN Energy Solutions) as a prominent designer of four‑stroke marine engines. This complementary expertise is expected to accelerate the development schedule.

Ship & Bunker highlighted that the hybrid‑electric system “features Everllence’s dual‑fuel hybrid‑electric propulsion”, reinforcing the notion that the vessel will be among the first of its size to incorporate such technology on a commercial scale. The article also suggested that the design aims at “improving the vessel’s efficiency and emissions performance as shipowners face tighter IMO carbon‑intensity requirements”.

Industry reception and next steps

TradeWinds framed hybrid‑electric propulsion as “the next efficiency, emissions saving and cost‑cutting step”, signalling broad industry interest in such solutions. Although the TradeWinds piece contains limited technical detail, its editorial stance reflects a growing consensus that hybridisation can bridge the gap between conventional diesel‑dominant fleets and future zero‑emission concepts.

Following the signing ceremony – attended by Pan Ke (Head of Sales & Projects, Four‑Stroke Everllence China) and Yang Chunhua (Technical Centre Deputy Director, Hudong‑Zhonghua) – both companies have pledged to share development milestones with customers. This transparency is intended to reassure ship owners that the performance claims of the DFE+ system will be validated through sea trials.

What this means for operators

For LNG carrier owners, the Everllence‑Hudong Zhonghua collaboration offers a tangible pathway to meet upcoming IMO CII thresholds without sacrificing cargo capacity. The hybrid‑electric layout promises lower fuel consumption per tonne of LNG transported, which translates into reduced bunker costs and a smaller carbon footprint. Operators that secure early slots on the newbuild programme will likely benefit from first‑mover advantages in emissions reporting and may gain preferential treatment under charter agreements that increasingly incorporate environmental clauses.

Moreover, the dual‑fuel capability ensures operational flexibility: vessels can switch between low‑sulphur fuel oil and LNG depending on market pricing and regional emission regulations. This adaptability mitigates exposure to volatile bunker markets while future‑proofing fleets for potential shifts toward greener fuels such as ammonia or hydrogen.

In practice, ship managers should prepare for integration of new monitoring systems required by the DFE+ architecture, including real‑time power management and emissions verification tools. Training programmes for engineering crews will also be essential to maximise the efficiency gains promised by the hybrid design.
