The whole rig consists of modules that do not exceed 12 tonnes, and is cost effective due to quick erection and dismantling of the rig using the respective drilling platform’s own crane.
The VDD 400.2, which is based on the same working principle as the VDD 400.1, has been developed and accepted in accordance with the Norwegian safety standards NORSOK
During the drilling, the pipe handler will operate automatically, while the insertion and extraction of drilling rods, pipes and other drilling equipment will be carried out at the touch of a button.
The pipe handling crane of the VDD 400.2 will have almost double the capacity of VDD 400.1 besides having a radius of 21 metres, reported Your Industry News.
For safety reasons, different movement sequences of the pipe handling crane will partially be automated, said the company.
The VDD system’s hydraulics is belived to enable precise steering and allow high loads to be transferred, despite the small size of its constructional elements.
