At Taizhou Changlong Shipbuilding Co., Ltd., we engineer vessels that redefine operational excellence across global waters. Rooted in China’s shipbuilding heritage since our founding in 2019 – yet drawing on 30+ years of expertise from the original Songmen Changlong Ship Construction Team (established in the 1990s) – we specialize in crafting high-performance, custom-designed ships for commercial, industrial, and scientific missions. Based in Taizhou, Zhejiang, our shipyard merges traditional craftsmanship with cutting-edge marine technology, delivering vessels that excel in durability, efficiency, and environmental compliance.

Core Capabilities: Precision Engineering for Diverse Maritime Needs

Our strength lies in transforming complex client requirements into seaworthy realities. We design and construct specialized small-to-medium vessels including fuel-efficient bulk carriers optimized for coal and grain transport across Asian trade routes, ice-class fishing boats engineered for Arctic trawling operations, low-emission Ro-Pax ferries serving Mediterranean island networks, and heavy-duty deck barges supporting offshore wind farm installations. Each project begins with our naval architects developing digital twin prototypes, simulating hydrodynamic performance and structural integrity under extreme conditions – from tropical storms to polar ice fields. We integrate robotic welding systems and AI-assisted quality control to ensure millimeter-perfect hull assembly, while advanced anti-corrosion coatings extend vessel lifespans in high-salinity environments.

Green Shipbuilding: Leading the Decarbonization Wave

Recognizing shipping’s pivotal role in global sustainability, we pioneer eco-innovations that slash emissions without compromising power. Our recent breakthroughs include:

• •

  Ammonia-fueled hybrid propulsion systems enabling carbon-neutral transoceanic voyages

• •

  LNG retrofit kits converting traditional tankers to dual-fuel operation, cutting SOx emissions by 99%

• •

  Solar-integrated deck designs powering onboard systems for research vessels

• •

  Hydrodynamic hull optimization reducing wave resistance by 18% in container ships

These technologies align with IMO 2030/2050 targets while delivering tangible ROI through fuel savings of 25–40%.

Global Impact: Vessels Engineered for Real-World Challenges

From the ice-strengthened "Polar Surveyor" research ship exploring Antarctic biodiversity to the "Coral Guardian" multipurpose workboat deploying artificial reefs in Southeast Asia, our vessels solve critical maritime challenges. One flagship project – the "Green Stream" Ro-Pax ferry – now transports 400 passengers and 50 vehicles between Greek islands using AI-optimized routing, cutting fuel consumption by 30% while enhancing comfort through zero-vibration electric azimuth thrusters. Another milestone: the "Pacific Trader" bulk carrier features our patented cargo hold moisture control system, preventing $2M/year in grain spoilage for Australian agri-exporters.

Partnering for the Future

As China’s premier private shipbuilder, we invest 8% of annual revenue into R&D – currently developing hydrogen fuel cell ferries and autonomous coastal barges. Our turnkey project management covers financing support, regulatory certification (ABS, DNV, RINA), and lifetime maintenance contracts. For operators seeking to modernize fleets, we offer retrofit packages enhancing efficiency, safety, and compliance.
