Chinese yard Shanghai Waigaoqiao Shipbuilding has delivered the final rig of its 13 jack-up fleet built during the rig boom a decade ago.

The delivery of JU2000E-design jack-up Guoshuo to China’s government-owned rig manager SinoOcean Offshore Assets Management means SWS has cleared its jack-up inventory, which had been stacked at its Shanghai yard for five years.

SWS said that Chinese offshore drilling contractor China Oilfield Service Ltd (COSL) has chartered the Guoshuo, but stopped short of identifying the operational region, although sources suggested that rig will head for the Middle East.
