MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202617062028 A) filed by Oag Engineering Sdn Bhd on May 15, 2026, for Method And System For Continuous Treatment Of Pipeline Internal Field Joints.
Inventor includes Chong, Jonathan Teik Cheh.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: The present invention relates to a method and system involving robotic crawlers in treating pipeline field joints, whereby the method and system enables simultaneous treatment of a successive number of joints within the pipeline by treatment units which are operated so as to subject each of said joints to consecutive different treatments. Particularly, the system comprising: a surface preparation crawler (300) comprising a surface preparation module (301) linked to a locomotion unit (200), wherein the surface preparation module (301) is configured at a rear end of the surface preparation crawler (300); a coating crawler (400, 500) comprising a coating module (401, 501) linked to a locomotion unit, wherein the coating module (401, 501) is configured at a front end of the coating crawler (400, 500), wherein the surface preparation crawler (300) and the coating crawler (400, 500) are arranged to travel within a pipeline in a manner whereby upon completion of a surface preparation of a first field joint the surface preparation crawler (300) is caused to move on from said first field joint to a next succeeding second field joint while the coating crawler (400, 500) treats the said first field joint whereby successive field joints are treated simultaneously. In this way, the system provides a significantly reduction in a total cycle time for pipe laying. Further, the system is able to avoid driving over a previously treated area thereby preventing contamination.
