J-Tube Design Life
As offshore assets go beyond their intended design life, the integrity of subsea structures in particular riser and J-Tubes becomes more critical. It is a common practice in the offshore industry to use J-Tubes as a method of installation of small diameter flowlines, electrical cables or pipeline bundles. Connecting a small diameter pipeline to the topside facilities through a small diameter riser is not very convenient in terms of supports.
To overcome difficulties of installation and protection, small diameter pipelines / cables are installed by pulling-in through J-tubes are now being used for housing umbilicals.
Our Tools
Utilising our vast knowledge and awareness, AISUS designed and manufactured several unique internal ultrasonic scanners, including “SCORPIUS” a gravity feed or crawler driven scanner which is controlled by a topside controller and can manoeuvre past bends and traverse along horizontal sections.
