On the afternoon of 23 October, after 26 days of round-the-clock work, Huafeng Shipyard waved off the ice-breaking, electrically-driven LNG carrier *Marguerite*—the first vessel of its type the yard has ever repaired. Her departure marks Huafeng’s formal entry into the top-tier LNG segment.
Measuring 299 m × 50 m, *Marguerite* is powered by three ABB full-revolving electric pods fed by six Wärtsilä 12-cylinder V-type tri-fuel gensets. Her four GTT No-96 membrane cargo tanks, with 0.7 mm Invar walls, give a total capacity of 174 000 m³. She is the world’s first ice-class LNG carrier with electric propulsion and the largest and most advanced vessel of her kind ever docked in Zhoushan.
The docking package covered ice-grade paint application, propulsion-system overhaul, insulation-safety-valve recertification and low-temperature cargo-system maintenance. Work scope included the main pods and generators, opening and inspecting all four cargo tanks, overhauling cargo and spray pumps, low-temperature valves and cargo compressors. The cargo pumps—precision machinery—were removed, serviced and re-installed under continuous protection.
To meet the quality demanded by LNG work, Huafeng upgraded workshop plant and built a new temperature-controlled workshop. An elite LNG project team planned every critical job in advance, organised specialised training, designed bespoke tooling and secured spares. Resources from both yards were pooled; the workforce pulled together and delivered the ship on schedule, earning high praise from owner and class.
The successful delivery has given Huafeng a full set of LNG-repair standards and operating procedures and a solid platform for chasing further large-LNG contracts.
In recent years Huafeng has poured capital into green repair technology and digital-yard development, leap-frogging in both capacity and capability. Early engagement with carbon-emission regulations positions the yard to serve global owners even better in the years ahead.
