China's first low-temperature ocean workover rig successfully developed

On June 19, the first offshore Workover Rig that can adapt to -20 ℃ operating conditions was successfully developed at Nanyang No.2 Machinery Group to fill the gap in this field, which will improve the safety of winter workover work in marine areas.

It is reported that the Bohai Sea winter temperatures as low as near -20 ℃, Nanyang two machines should CNOOC Tianjin branch requirements, design and manufacture of the first low-temperature ocean workover rig. The maximum hook load of the machine is 180 tons. The main structural parts are all made of low temperature materials and can fully meet the winter marine climate. The whole equipment adopts the modular structure design and can be divided into three large modules or 11 small modules, of which Large modules facilitate the hoisting of the sea, small module convenient way to transport, greatly improving work efficiency.

It is understood that Nanyang two machines as China's first pioneer in the development of offshore workover machine professional, creating a number of first: China's first marine workover rig, the first DC SCR drive ocean workover rig, the first Taiwan's small module easy to disassemble and install a marine workover rig, the first largest tonnage offshore drilling rig, the first AC variable frequency drive marine workover rig are made by the company, many times to fill gaps in the domestic, has now developed the production of oceans More than 70 workover rigs made a great contribution to the localization of offshore workover rigs.

In addition, the company, as the developer of the first cryogenic drilling rig in China, continuously improved the cryogenic series of products and successively developed 1000-70000 m Drilling Rigs capable of satisfying the drilling requirements at minus 45 degrees in the alpine region. It exported to Russia, Canada, Kazakhstan, etc. in batches Countries and regions.

The successful development of this low-temperature marine workover rig is the perfect combination of low-temperature technology and marine technology by Nanyang II, which will drive the domestic marine workover rig to enter a new area.
