China Daily: Light up the Way, Bridge Two NationsTo CMEC Builders in
Pakistan Located in the Indus Plain on the South Asian subcontinent,
Pakistan is a nation with a long history and a profound culture where
power supply ran short for many years and even failed to meet the needs
of people’s everyday life and the country’s economic growth. It was
against such a backdrop that China Machinery Engineering Corporation
(CMEC) got into Pakistan’s power project contracting market thirty years
ago. Since then, CMEC has endeavored to bring about exciting changes on
this ancient land, despite all the challenges. With power plants built
and put into operation one after another, CMEC has brought tangible
benefits to local people and made its due contribution to the
development of the country’s power industry.Over the past three decades,
CMEC builders have been sent in groups to Pakistan. There, they have
worked hard with no complaint and notched up one success after another.
The first came in 1983 when they delivered the 210MW fuel-fired
Generating Unit 4 for the Guddu power plant. Following projects include
the 210MW fuel/gas-fired Units 2, 3, & 4 for the Jamshoro power plant
completed in 1991, the 2×210MW fuel/gas-fired Units 5 & 6 for the
Muzaffargarh power plant completed in 1995, the 320MW fuel/gas-fired
Unit 4 for the Muzaffargarh power plant completed at the end of 1997,
the gate & hydraulic hoist equipment for the 5×300MW Ghazi-Barotha
hydropower plant completed in 2002, the 3000KW hydropower plant
completed in 2004, the turnkey project of the 225MW Saif combined-cycle
power plant completed in 2010, and the NEELUM-JHELUM hydropower plant
under construction.The 210MW fuel-fired Unit 4 of the Guddu power plant
represents China’s debut in the international thermal power market and
the first international engineering project China has contracted and
built based on export seller’s credit. Top Chinese enterprises formed
the most competitive project team and it took the team nearly three
years to complete the project, 22 days ahead of schedule. Through the
project, CMEC made a successful shift from an industrial and trade
company to an outstanding players in China’s international project
contracting sector.The Saif combined-cycle power plant, whose contract
was signed in May 2007, is the world’s first power plant with a
dual-fuel 6FA gas turbine unit. With the joint efforts of the entire
project team, no major equipment quality or safety related accidents
happened from the debugging stage to the end of the warranty period; the
unit maintained stable operation and passed the stability test
successfully. The final completion certificate was awarded in December

In addition to earthquake early warning, China also has been trying to
forecast quakes, which is much more difficult, Zheng said.

It has already finished testing an earthquake alert system for
high-speed trains, and the system is expected to be extended to the
country””””s entire high-speed rail network, said Zheng Guoguang,
vice-minister of emergency management. He made the remarks ahead of the
International Day for Disaster Reduction, which falls on Saturday this
year.

  1. It was put into operation one month ahead of schedule despite that
    construction had started half a year later than three other units of the
    same category in Pakistan.CMEC contracted the NEELUM-JHELUM hydropower
    plant project in 2007, for the design, supply, installation and
    construction of metal structures, and electrical and mechanical
    engineering. The power plant, known as the “Three Gorges Project in
    Pakistan”, is the largest one of its kind in the country with the
    largest underground works in Asia and the largest surge shaft in the
    world.From the Guddu power plant to the NEELUM-JHELUM hydropower plant,
    CMEC has witnessed the initial development of power plants in foreign
    countries. Based on the understanding of international practice and
    rules about contracting international power project, CMEC has developed
    its rules and approaches for the management of international projects as
    well as a team with strong international trade background and rich
    hands-on and technical experience in the organization and management of
    international projects.Through 30 years of endeavor, CMEC has grown into
    a leading international project contractor and service provider. The
    international projects it has contracted and the international trade it
    has engaged in involve more than 150 countries and regions across the
    five continents. The projects cover such fields as electrical power,
    transport, electronic communications, housing construction,
    manufacturing and processing plants, environmental protection, mining
    and resource exploitation. Its performance in the electrical power
    sector is particularly outstanding. By the end of 2011, CMEC had
    completed three 600MW supercritical coal-fired power plants.Looking back
    at those hard years in Pakistan’s power project contracting market, CMEC
    will continue to press ahead and make the greatest efforts to promote
    the cooperation with Pakistan in an all-round and in-depth manner and
    push the China-Pakistan friendship to a new stage, based on the
    principle of sincerity and mutual benefit.分享:.fenxx

It has already finished testing an earthquake alert system for
high-speed trains, and the system is expected to be extended to the
country””””s entire high-speed rail network, said Zheng Guoguang,
vice-minister of emergency management. He made the remarks ahead of the
International Day for Disaster Reduction, which falls on Saturday this
year.

Zheng said the system will probably be put into operation first in
Southwest China, considering the high frequency of earthquakes there.
For example, the Sichuan-Tibet railway, which is under construction,
crosses four earthquake faults where 14 earthquakes above magnitude 7.0
have occurred.

新葡萄京娱乐场官网,Seismic sensors could detect the first energy that emerges from a quake
before the jolt begins. This makes it possible to warn those in affected
areas before they feel the impact. The farther people are from the
epicenter, the longer they would have to respond in the event of a
quake.

Zheng said one challenge that China faces in earthquake alerts is the
particular nature of earthquakes in the country. Most earthquake
epicenters around the world occur along tectonic plate boundaries, many
of which are located in the ocean. In China, however, most tremor
epicenters occur within the plate on which the country sits, he said.
Such countries as Japan and Mexico usually have more time to alert
people to a quake, since it takes time for a quake originating in the
ocean to affect land, Zheng added.

Even before the system won approval, the administration teamed up in
2012 with the Ministry of Railways, which has since been reshuffled into
China Railway Corp, to establish a team to research an earthquake alert
system for high-speed railway.

The early warning system, known as the National Seismic Intensity Rapid
Reporting and Early Warning project, was approved by central authorities
early last year. It will include more than 15,000 observation stations
across the country, at a cost of almost 1.9 billion yuan ($274 million),
and 3,3500 service terminals in national and provincial government
bodies that are related to earthquake relief, as well as in public
institutions and vital infrastructure and utilities, such as nuclear
power plants.

China will build a nationwide earthquake early warning system by 2023,
said a senior emergency management official.

The system developed by the team has been tested on several railway
lines in Fujian and Shanxi provinces and works very well, Zheng said,
adding that his administration will continue to cooperate with China
Railway to extend the system to all high-speed trains in the country.

Although China””””s quake alert system for high-speed trains uses
advanced technology, the nationwide early warning system is needed for
it to work best, Zheng said. Therefore, the country should accelerate
construction of the National Seismic Intensity Rapid Reporting and Early
Warning project, he said.

“The Chinese government is the only one in the world that considers
earthquake forecast research as its duty,” he said.

epicenter, the longer they would have to respond in the event of a
quake.

China is among the countries that suffer the most from earthquakes. From
1900 to 2017, China was hit by an annual average of 18 earthquakes above
magnitude 5.0. So far this year, the number stands at 10.

Observation stations will be set in different areas according to
earthquake frequency and the potential risk of and effects from
disasters. The North-South Seismic Belt, which encircles most of
Sichuan, Gansu and Yunnan provinces, will be one of the key areas for
such stations, said Zheng, who also is head of the China Earthquake
Administration.

The completion of the field test of the alert system on the
Datong-Xi””””an high-speed railway in August marks the quake alert
system””””s shift from the research and development stage to actual
use, the administration said.
