Jiangsu Rongsheng Heavy Industries Group Co Ltd began building CNOOC 201, a deepwater pipe laying and lifting vessel for China National Offshore Oil Corporation in Rugao Port of Nantong City in Jiangsu Province on September 16th 2008. CNOOC Engineering plans to input CNY 15 billion(USD2bn) in construction of a series of deepwater equipment including deep sea drilling vessels, ready to focus on deepwater prospecting, since most of the country's newly discovered oilfields are deep undersea. According to South Korean companies' experience, the gross margin of offshore engineering reaches up to 30%, while that of China's domestic shipbuilding industry has only hit 18% to 19% since the beginning of 2008.
