A trailing suction hopper Dredger or TSHD trails its Suction Pipe when working, and loads the dredge spoil into one or more hoppers in the vessel. When the hoppers are full the TSHD sails to a disposal area and either dumps the material through doors in the hull or pumps the material out of the hoppers. Generally these full block ships have a length between 40 to 130 m. The vessels are, highly manoeuvrable and they have a high installed power to operate the dredging equipment. Vessels operate regularly in shallow water conditions.

With the substantial increase in the demand for important equipment manufacturing industries such as national defense, aviation, high-speed rail and automobiles, China's machine tools have also achieved rapid development, and machine tool technology has made remarkable progress in high-speed, composite, precision, multi-axis and other aspects. And a series of breakthroughs.
Machine tools also play an important role in the industrial processing field. In the past year, China's industrial manufacturing industry has undergone a steady transformation, which has also caused a certain change in the demand for machine tools. That is, the demand for medium and high-end products has grown faster than low-end products, and the industry has begun to move toward high-end.
In 2013, China's machine tool industry continued its overall downward trend in the past two years, and the market demand structure has undergone tremendous changes. The global economic rebalancing and the slowdown of China's economic growth have had a comprehensive and profound impact on the machine tool industry. The growth factors that have been developed in the past 10 years have undergone profound changes, and their outstanding features are manifested in two aspects. That is, the significant reduction in the total demand and the accelerated upgrading of the demand structure. At the same time, in the past two years, the structure of China's imported machine tool products has undergone many obvious changes. The domestic high-end demand has been driven, and the status quo of high-end machine tool imports has not changed. The complete line of equipment, intelligent manufacturing islands, digital workshops, manufacturing services, etc. Development has not yet formed a scale advantage, which will also be the goal of China's machine tool industry to face new changes and create a new future.
It can be said that the level, variety and production capacity of the machine tool directly reflect the comprehensive strength of a country's industry, and the birth of China's machine tools is slightly lagging behind the United States and Germany. After nearly half of the world's development, Chinese machine tools lag far behind Germany. In the United States, Japan and other countries, domestic machine tools are mainly based on low-end economy and mid-range popular machine tools. Local machine tools still have a big gap with foreign machine tools in terms of accuracy and reliability.
Although the country has implemented a major project of “high-end CNC machine tools and basic manufacturing equipmentâ€, and plans to base 80% of the high-end CNC machines and basic manufacturing equipment required for the four major fields in 2020, only the large-scale high-efficiency CNC machines of Jiji Machine Tools are currently available. A project of automatic stamping production line has successfully achieved commercialization, and it is still necessary to continue efforts on key components and high-grade CNC systems.
In the future, with the increasing emphasis on domestic high-end machine tools, local machine tool brands will usher in a new period of development after strengthening talent training.
