Japan develops the world's first seawater prediction system

Japan's Marine Research Institute recently announced that they have successfully developed the world's first seawater prediction system and established a consortium of limited liability companies that use the system to provide predictive data services to shipping companies. Based on the data provided by the consortium, the ship can determine the correct shipping plan to reduce sailing time, reduce fuel consumption and reduce greenhouse gas emissions.

The seawater prediction system uses supercomputers to calculate the seawater flow direction and water level, water temperature and other data observed by artificial satellites and nearly 3,000 buoys floating on the sea, and can predict the seawater flow in a specific sea area up to 2 months later. The strength of the waves and so on. Moreover, the data is updated every day, and the ship is sent an e-mail through the communication satellite to make reference for the ship to decide the navigation route. For example, by calculation, ships using the Kuroshio flow from Asia to North America can save a maximum of 2% of fuel consumption per ship. If ships around the world use this forecasting system, it is estimated that 146,000 tons of diesel can be saved each year, reducing fuel consumption by about 5.3 billion yen (about 380 million yuan) and carbon dioxide emissions of nearly 440,000 tons per year.

"The forecasting system is a far-reaching business for the status quo of global warming and rising crude oil prices," said Yamato Jun, a corporate representative of the corporate consortium and a professor at the University of Tokyo. "I hope that the accuracy of prediction can be further improved in the future." ."

Grading Bucket

CATSU Excavator Grading bucket is a type of Excavator Bucket that is specifically designed for digging and leveling soil, gravel, and other loose materials.

It typically has a flat bottom and straight sides, allowing it to move material in a smooth and controlled manner.

CATSU Grading buckets are commonly used in construction, landscaping, and agricultural applications to create level surfaces, build foundations, and prepare land for planting.

Some excavator grading buckets may also have teeth or cutting edges to help break up harder materials, such as rock or concrete.
