Zhenhua Heavy Industries, also known as ZPMC, the world's biggest port machinery manufacturer, completed its first rig on Friday. It is the most advanced self-developed offshore drilling platform in the nation.

The rig, called KS Java Star 2, is the outcome of collaboration between ZPMC, formerly known as Shanghai Zhenhua Port Machinery Co, and Friede Goldman United Ltd, the US-based designer and service provider for drilling platforms.

ZPMC's parent China Communications Construction Co Ltd acquired Friede Goldman in 2010 for $125 million.
