Zhoushan in East China's Zhejiang province has in recent years been making efforts to develop green technologies to bolster its ship maintenance industry.

For example, the city has channeled more resources towards upgrading its ship repair equipment, which would in turn aid the expansion of its high value-added ship maintenance business.

IMC Shipyard (Zhoushan) Co Ltd is one of the leading companies in terms of using green technologies.

Wang Dongping, the general assistant manager of IMC, said that 11 vessels are now under repair at his shipyard, and his company has received orders from ship owners in Germany, Singapore, Norway and Switzerland.

He added that the maintenance of oil tankers, pure car and truck carriers account for 60 percent of the total, and the output value of ship maintenance increased by 20 percent compared with the same period of last year.

COSCO Shipping Heavy Industry Co Ltd is another company that has been focusing on developing core technologies. The company completed the maintenance of the world's largest LNG dual-fuel container ship last year.

The city, which is currently home to 91 shipbuilding and marine engineering enterprises, has the capacity to build 7-million-deadweight-ton vessels and repair three thousand 10,000-ton ships a year, accounting for more than one third of the country's total.
