On 29th August, 2016, the commissioning ceremony of CREC R73, a gripper TBM refurbished by CREG took place in Bien Hoa, Dong Nai, Vietnam. 


The 3.9m diameter gripper TBM was supplied by former Wirth (acquired by CREG in 2013) and applied to the Todini Project in Italy. With the completion of its refurbishment, the machine shall work for the Da Nhim Hydropower Plant Expansion project in central Vietnam. 


The project contractor CC47 asked CREG for the refurbishment to fit for his new project. CREG technical staff has successfully accomplished thorough testing, diagnosis and repairs of the TBM cutterhead, shield, drive and electric systems. Moreover, anchoring and probe drilling system and grouting system have been added to improve the machine’s adaptability to complicated geologies. 


CC47 was very impressed with the professional skills and responsible attitude of the technical staff dispatched by CREG. A consecutive tunnelling service contract has been signed between CC47 and CREG for the next phase of project work to continue this sound cooperation. 

Attended at the commissioning ceremony were Mr. Nguyen Luong Am, President of CC47, Mr. Zhang Zhiguo, Deputy General Manager of CREG, Mr. Wu Xiaobo, General Manager of CREG Germany.
