OREANDA-NEWS. July 23, 2013. China's first integrated F18-21 BOP unit passed the performance test at CNPC Baoji Oilfield Machinery Co., LTD (BOMCO).

This integrated BOP unit is specifically designed for truck-mounted drilling/workover rigs, featuring smaller size, weight and height and much reduced material and manufacturing costs as compared to regular ones.

The design enables the main bodies of the annular BOP, ram BOP and cross tee to be integrated by cast molding. As such, the unit structure is more compact and easy to be installed at drilling sites, so as to effectively reduce labor intensity and shorten operating time.
