The Qatargas 2 LNG project (QGX) (for the construction of Trains 4 and 5) is the world’s first LNG plant project of its scale and therefore is also the largest. Trains 4 and 5 are each designed to produce 7.8 million tons of LNG per year from natural gas collected in the North Field off Ras Laffan, Qatar. In order to expand the scale of the plant, we repeatedly designed and simulated every possible situation to solve technical issues. The area of the site is 380,000 m2 (equivalent to the area of about 30 times the size of Tokyo Dome), and the number of workers who engaged in the construction of the trains, including people from 40 countries around the world reached about 27,000 per day at peak times. Qatar aims to produce 77 million tons of LNG per year by 2010, becoming the world's largest LNG producing country. The Qatargas Expansion Project was only a part of the bigger national project. Chiyoda’s accomplishments in the construction of the LNG trains in Qatar and contributions to the global environment through this project, along with Chiyoda’s other accomplishments through two projects executed at the same time, were all highly regarded. It was for these achievements that Chiyoda received the Minister of Economy, Trade and Industry’s Prize, the highest prize among the Third Monozukuri Nippon Grand Awards (Overseas Operations Section) (sponsored by the Ministry of Economy, Trade and Industry; the Ministry of Land, Infrastructure, Transport and Tourism; the Ministry of Education, Culture, Sports, Science and Technology; and the Ministry of Health, Labor and Welfare). This is the first time such an honor has been given in the engineering industry to a company engaging in overseas operations.

In Qatar in the Middle East, in rains only two to three days a year. Sandstorms sometimes occur, but it is mostly sunny every day. It is extremely hot in the summer and the temperature sometimes hits 50 degrees with 100% humidity. The air-conditioned office was cool, but everybody was required to carry his or her own canteen for safety and health reasons when leaving for the construction site. Because Qatar is an Islamic country, and people from various countries and cultures were involved with the project, the project was carried out in a culture very different from Japanese culture, especially during Ramadan (fasting).
