CIMC Sanctum Sets Another Record: Delivers China’s Largest and Heaviest 685 m³ LNG Double-Hull Marine Fuel Tank

Recently, as the deck barge slowly departed from the harbor basin of the Zhenjiang Heavy-Duty Terminal in Zhangjiagang, it marked the successful delivery of two 685 m³ units developed by CIMC Sanctum. LNG The marine fuel tank has been successfully delivered. According to reports, this is currently the largest-capacity and heaviest double-walled marine fuel tank project ever delivered in China.

According to available information, the double-walled marine fuel tank, also known as a vacuum-insulated fuel tank, is a component of the marine LNG fuel supply system that meets In my opinion (International Maritime Organization) C Requirements for the type compartment LNG A vacuum-insulated storage tank is LNG One of the core components of the fuel system. 2019 In mid-year, Sinopec Sanctum Energy signed an agreement with MAN, a globally renowned provider of powertrain solutions based in Germany. 4 Taiwan 685m ³ Marine LNG Double-layered C Type-independent tank; the one delivered this time is one of them. 2 Taiwan.

These two “giant” units are long. 30.5 Rice, diameter 6.6 Rice, with a total weight of 234 tons, which will be used by the Swedish shipping company Chang 241.7 Rice, lane 5800 A dual-fuel super Ro-Ro vessel for rice transport, which is currently the world’s largest newly built dual-fuel Ro-Ro ship and an ice-class Ro-Ro vessel, classed by Lloyd’s Register. This system operates through TCS The internal piping system, submersible pumps, surge tanks, and other equipment provide power for the ro-ro vessel’s engines and generators, virtually eliminating sulfide emissions in the exhaust while effectively reducing 80% The above nitrogen oxide emissions, 20%-25% of carbon dioxide emissions.

This year 7 This month, CIMC Sanctum has successfully delivered two units to MAN Sweden. 500m ³The double-walled marine fuel tank fills a gap in the history of domestic manufacturing. Leveraging years of extensive experience in the R&D and production of marine equipment, and through innovative design and process optimization, it has achieved an internationally leading level in both R&D and manufacturing processes, making it the benchmark for double-walled marine fuel tanks—and indeed for double-walled storage tanks—across the industry. This successful delivery… 685 m ³ LNG The double-walled marine fuel tank once again serves as strong evidence of CIMC Sanctum’s comprehensive strength.

Innovative Design, Rising to Challenges

With no established precedents to follow, we must forge new ground even in the face of daunting challenges. To meet global demands for clean, environmentally friendly marine fuel tanks that are both larger and lighter, our tank technology team has engaged in extensive communication and in-depth discussions with customers, shipyards, classification societies, and other stakeholders.

During the manufacturing process, designers conduct thorough analyses based on actual conditions—such as workshop production capacity, on-site process capabilities, and transportation and lifting capacities—and continuously refine and optimize the design to meet the requirements of real-world operating conditions.

Tightly linked and advanced in an orderly manner.

Due to the large volume and heavy weight of the product, the project places higher demands on processes such as cutting, edge planing, rolling, and assembly, thereby increasing the manufacturing difficulty. In particular, 2020 At the beginning of the year, the pandemic raged, disrupting workers’ return to work and material procurement, thereby compressing the originally scheduled manufacturing timeline. To ensure on-time delivery, multiple production processes were simultaneously advanced following the resumption of operations.

From material cutting at the end of April to 11 The project was successfully delivered on time, despite numerous challenges along the way. The project team maintained tight coordination at every stage and advanced the work in an orderly manner, completing it in just 6 Completing a vessel of such enormous capacity within a mere month of pure fabrication represents a groundbreaking achievement—both for Sanctum and the industry at large. In the face of the myriad safety challenges posed by this “colossal behemoth,” on-site lean safety management ensured zero accidents, thereby fully demonstrating Sanctum’s formidable manufacturing prowess in the cryogenic equipment sector.

Multiple layers of quality control to ensure strict quality standards.

The complexity of the manufacturing processes also poses significant challenges to quality inspection. As an essential safeguard for the safe operation of tank vessels, quality control for these projects involves extensive collaboration among the quality assurance team, classification societies, engineering, production, and process departments from the very outset to develop an Inspection and Test Plan (ITP) that clearly defines critical control points. This ensures rigorous inspection and effective control over every stage that impacts product quality—ranging from material receipt and fabrication/assembly to weld inspection, hydrostatic testing, and leak-tightness testing—thereby guaranteeing compliance with relevant international laws, regulations, and standards and laying the necessary foundation for ensuring vessel quality and safety.

Carefully organized, ensuring smooth operation

The marine tanks shipped this time are not only the largest equipment ever manufactured by CIMC Sanctum, but also the largest double-walled LNG marine fuel tanks currently in China. Their sheer size makes them impossible to transport by ordinary freight vehicles, making the seamless delivery of these products to the shipyard a critical task for the Shipping Department. To ensure smooth delivery, the department proactively coordinated with the maritime traffic management authorities and leveraged external logistics capacity by launching a public tender to secure an efficient and safe transportation solution. To guarantee cargo safety, every step—from packaging and loading to securing the cargo and clearing road obstructions—was meticulously managed throughout the entire process. A dedicated escort team comprising more than 50 personnel, over ten heavy-duty trucks, and emergency response vehicles accompanied the shipment along the five-kilometer route from the factory to the terminal. After two days and two nights of land transport and precise lifting operations, the shipment was ultimately completed successfully.

2 units remaining 685m ³The ship tanks are being systematically manufactured at the factory and will 2021 Delivery was completed at the beginning of the year. To date, Sunda Yin has cumulatively provided to numerous renowned shipyards worldwide 50 We provide dual-layer marine fuel tanks tailored for multiple offshore vessel projects of varying capacities, and have entered into strategic cooperation framework agreements with several internationally renowned power system solution providers. Our products’ quality and operational performance have earned the unwavering trust of customers worldwide.

As a transitional fuel on the shipping industry’s path toward a zero-carbon future, LNG serves as a green “accelerator” for the global shipping sector, with LNG Fuel power has already become the primary choice for ship operators worldwide. CIMC Sunda will seize this opportunity to further enhance the competitiveness of its marine tank products in the international market, delivering cleaner and more environmentally friendly solutions to vessels around the globe through superior product quality. LNG Marine fuel tank products contribute to global energy conservation and emission reduction.
