'an improved process for manufacturing rotary housing of oil rig'

摘要

The invention relates to an Improved process for manufacturing rotary housing of Oil Rig which uses a combination of castings for the higher section modules materials, and wherein plate members for the lower cross section materials are used in the manufacturing process of the rotary housing. The integration between the plates and the castings is ensured by welding with compatible materials. This results in a robust structure with improved performance capability.
