Asia's largest offshore oil production platform finished its floatover installation on Monday, platform operator China National Offshore Oil Corp said.

With the completion of floatover installation of the Enping 15-1 platform, China's design, construction and installation capabilities of super large offshore oil and gas production facilities has reached advanced international standards, it said.

Floatover installation is an effective installation method for topsides of offshore platforms and has become a cost-effective alternative for offshore construction over the past few decades.

According to Yuan Wei, deputy director of CNOOC's Shenzhen branch, a series of homemade equipment has reduced engineering investment and can save more than 30 percent of annual maintenance costs.

Enping 15-1 is a major offshore facility ensuring the operation of the Enping oilfield cluster, which will include four offshore drilling platforms to jointly develop six new oilfields.

Peak daily oil output will reach around 5,000 tons during the second half this year when the project is put into operation, and is expected to inject further momentum to the economic development of the Guangdong-Hong Kong-Macao Greater Bay Area while further ensuring the country's energy security, the company said.
