New ship technology boosts clean energy development and utilization

As the world's demand for natural gas increases, the route to extract natural gas will be farther away, and the depth of submarine oil and gas exploration will gradually deepen, and higher transportation technology will be needed as a support. LNG carriers came into being. This is a unique form of storage and transportation of natural gas, which is very conducive to reducing the storage cost of natural gas and the long-distance transportation of natural gas. At the same time, natural gas is purified and liquefied, which is cleaner than pipeline transportation. The LNG carrier is a special vessel for transporting liquefied natural gas at a temperature of minus 162 degrees Celsius. It is also an internationally recognized "high-tech, high-difficult, high-value-added "three high" product.
The data shows that China currently accounts for 40% of the world's shipbuilding capacity, and China has become the world's largest shipbuilding country. However, the orders accepted by Chinese shipyards are mainly used in business. In the high-end and high-value shipbuilding industry, China's advantages are not prominent. In 2011, a total of 16 LNG carriers were delivered worldwide, including 13 in South Korea and only 2 in China.
In order to improve the level of China's shipbuilding technology, GE is currently designing and developing a gas turbine-driven LNG carrier jointly with Dalian Shipbuilding Industry Group and Lloyd's Register of Shipping. This ship uses a dual-fuel engine electric propulsion system, gas turbine. The temperature is as high as 520 degrees Celsius, so there is huge fuel that can be recovered, and the steam generated by the recovered turbine is re-entered into the steam turbine generator to generate electricity. In addition to this gas-powered LNG carrier, GE recently exhibited innovative technology products tailored for China's marine and marine engineering at the China International Maritime Exhibition, including dozens of products including power, propulsion and positioning. Product or model. In addition, deep-sea drilling vessels capable of operating in harsh environments, mining vessels equipped with floating mining storage and offloading devices, and LNG carriers that transport natural gas directly from customers to deep waters of several hundred meters, this series Technological innovation has promoted the further development and utilization of clean energy.
The technological innovation of the shipbuilding industry will also bring substantial benefits to China's economic growth. According to a collaborative study by international maritime research institutes Clarkson, Morgan Stanley and GE, China's global market share of high-value, high-tech ships is only 1% higher. By 2020, the industry is expected to achieve cumulative revenue growth of 40 billion US dollars. .
