On June 28, 2025, a significant event in the shipbuilding world took place at Penglai Zhongbai Jinglu Ship Industry Co., Ltd. (Jinglu Shipyard) with a naming ceremony for two new MR (Medium Range) chemical tankers. These vessels, named “WECO MEMPHIS BELLE” and “WECO SENNA,” were built for Hartree Partners, a global energy and commodities firm.
Leap Forward
Jinglu Shipyard has delivered two new-generation MR chemical tankers that represent a significant leap forward in the transportation of challenging liquid cargoes, combining high-end capacity with advanced green technologies.
These vessels boast impressive specifications:
- Dimensions: 183.1 meters in length, 32.2 meters in beam, and a design draft of 11.0 meters.
- Cargo Capacity: Equipped with 20 cargo holds, these are considered high-end vessels for their type globally. They are capable of simultaneously transporting up to 14 different kinds of goods, including highly corrosive substances like hydrochloric acid and sulfuric acid. This versatility is crucial for the chemical tanker market.
A key highlight of these new tankers is their integration of cutting-edge green environmental protection technologies, which significantly reduce greenhouse gas emissions and enhance energy efficiency:
- Selective Catalytic Reduction System (SCR): This system is vital for reducing nitrogen oxides (NOx) emissions. It works by injecting a urea-water solution into the exhaust gas stream, which then reacts with NOx over a catalyst to convert it into harmless nitrogen and water.
- Desulfurization Tower (Scrubber): This technology removes sulfur oxides (SOx) from exhaust gases, ensuring compliance with stringent sulfur emission regulations.
- Shaft Generator: This system generates electricity from the main engine’s rotation, reducing the need for auxiliary engines and thereby cutting fuel consumption and associated emissions.
- Pre-propeller Energy-Saving Duct: Positioned ahead of the propeller, this duct optimizes water flow into the propeller, improving propulsion efficiency and further reducing fuel consumption.
- High-Efficiency Twist Rudder (with Rudder Ball): This advanced rudder design, with its twisted profile and integrated rudder bulb, recovers energy from the propeller slipstream and minimizes resistance. This not only further reduces fuel consumption but also significantly enhances the vessel’s maneuverability.
These technological integrations demonstrate the innovative advantages of this vessel type in both technical configuration and practical application, achieving a seamless blend of high-efficiency energy saving and environmental protection.
