Ocean drilling is known as the "crown" of marine science and technology. Built by the China Geological Survey of the Ministry of Natural Resources in close collaboration with more than 150 units, the "Meng Xiang (Dream)" has a total tonnage of about 33,000 tons, a cruising range of 15,000 nautical miles, and a self-sustaining power of 120 days. It will provide important equipment support for the exploration and exploitation of ocean energy resources to ensure national energy security and a "core weapon" to support the construction of a maritime power.

Background

With the continuous development of China's marine resources and deep-sea scientific research, more high-tech scientific research platforms have been put into use, representing China's continuous innovation and breakthroughs in the field of marine. As China's first self-designed and built ocean drilling ship, "Meng Xiang" carries missions in the field of deep-sea resource exploration and scientific research. The vessel is not only equipped with advanced offshore drilling technology, but also innovates in many aspects, especially in terms of liquid nitrogen supply, using a 20 liters/day liquid nitrogen generator supplied by Scala in Hangzhou, which provides reliable liquid nitrogen guarantee for the crew's scientific research and cryopreservation equipment.

Demand Analysis

The main tasks of "Meng Xiang" include marine resource exploration, deep-sea environmental monitoring, and marine science experiments, etc., which will need the vessel sailing in the deep sea for a long time. These tasks not only place high standards of technical equipment, but also pose extremely high challenges to the day-to-day logistics on board. As an important cooling and protective medium, liquid nitrogen plays a vital role in deep-sea drilling and scientific exploration, especially in extreme environments with high temperature and high pressure. The application of liquid nitrogen involves sample preservation, equipment cooling, scientific experiments, environmental control and other aspects.

However, in the working condition of ocean drill ships, the traditional liquid nitrogen supply approaches have problems such as difficult transportation, high cost, and harsh storage conditions. To overcome these challenges, Meng Xiang's scientific team needed a device that could provide a stable supply of liquid nitrogen and cope with the harsh environment at sea.

Scala Solution

After many investigations and technical comparisons, Hangzhou Scala's 20 L/day liquid nitrogen generator became the ideal choice for the ship. In addition to its efficient liquid nitrogen production capacity, the generator also offers the following unique advantages:

1. Independent production, no external supply: The liquid nitrogen generator supplied by Scala can operate stably for 24 hours every day according to the demand of the ship, and produce liquid nitrogen independently, avoiding the high cost and instability caused by traditional liquid nitrogen supply approaches. During long-term sea voyages, the crew does not need to rely on an external supply of liquid nitrogen, which greatly increases the independence and flexibility of the mission.

2. Reliable performance and efficient work efficiency: The liquid nitrogen production capacity of 20 liters/day fully meets the liquid nitrogen needs of the scientific research team and other equipment. In the long-term offshore working environment, the generator can stably output the required liquid nitrogen to ensure the normal operation of scientific research experiments and equipment.

3. Wind and wave resistance and stability: The liquid nitrogen generator adopts high-strength, corrosion-resistant materials and special design, which can operate stably in the offshore environment with strong winds and waves. In addition, its equipment system has an intelligent monitoring function, which can detect the operation status of the equipment in real time, adjust and maintain it in time, and ensure the uninterrupted supply of liquid nitrogen.

4. Green and low energy consumption: Scala's liquid nitrogen generator is low energy consumption and high efficiency, which meets the requirements of "Meng Xiang" for environmental protection and energy saving. The energy consumption during the operation of the equipment is extremely low, which not only saves energy, but also reduces the impact on the environment, which is in line with the development trend of green technology.

Successful Application and Effect

Ever since the vessel was put into use, Scala has kept an eye on the performance of the liquid nitorgen generator. Up to now, the stable operation of the machine has provided sufficient liquid nitrogen for the ship and ensured the efficient operation of various scientific research equipment and instruments. In addition, the ship's scientific experiments were carried out smoothly, and Scala's liquid nitrogen generator played a key role in sample preservation, cryogenic storage and experimental environment control.

During the future missions of "Meng Xiang" , Hangzhou Scala will continue to pay attention to the operation of the generator, so as to ensure that the crew no longer needs to worry about the supply of liquid nitrogen during long-term deep-sea operations.

Conclusion

The successful application of Hangzhou Scala's 20 liters/day liquid nitrogen generator on "Meng Xiang" ocean drilling ship fully demonstrates the leading position of Scala brand in liquid nitrogen solutions. Through in-house design, innovative technology and reliable after-sales service, Scala brand liquid nitrogen generator contributes to China's continuous progress in deep-sea resource exploration and marine scientific research.

In the future, Scala will continue to be driven by scientific and technological innovation, promote the technological progress liquid nitrogen generators, and provide more stable and efficient solutions for more scientific research platforms.
