Chinese yard Cosco Shipping Heavy Industry has delivered a jack-up rig to compatriot company SinoOcean Offshore Assets Management for operation off the Asian nation.

The delivery is based on a memorandum of understanding reached between SinoOcean and Shandong Marine Group in October last year to charter and manage offshore drilling rigs the latter has ordered at Chinese yards.

The delivered rig SinoOcean Prosperous, formerly known as Energy Engager, is a Super 116E jack-up and was ordered by Shandong Marine’s rig owner Northern Offshore at Cosco’s Dalian yard in 2013.

The rig was completed and christened in 2017 but has been idle at the yard due to a lack of employment amid to global oil market downturn.

The ABS-classed rig is 74.09 metres long, 62.8 metres wide and is capable of working in water depths of 106.68 metres and drilling to well depths of 9144 metres. It is equipped to accommodate 120 people.

Northern Offshore also has a similar rig, Energy Encounter, at Cosco Dalian without a charter.

Upstream understands from contracting sources that government-controlled SinoOcean now owns and manages the rig.

In May last year, Northern Offshore’s jack-up rig Energy Edge sailed from Chinese yard Shanghai Waigaoqiao Shipbuilding for operations off Qatar, where it will participate in Qatar Petroleum's huge North Field Expansion project.
