5th Week of Internship

In oil and gas, pipeline is not laid alone on the ground or seabed. Sometimes, it will be clamped with the other pipe or cable along the pipeline. Pipeline clamp exist in various types. Some of them are piggy back clamps, riser clamps and umbilical clamp.





Piggyback clamping system uses a moulded saddle, tailored to the radius of the main line and is secured by circumferential straps. The saddle, which encompasses the secondary line holding it in place, has an axial split on its base to allow easy installation of the secondary line.



Clamps can be manufactured from various materials, including rubber, polypropylene and polyurethane elastomer and etc.







Metallic straps are offered in carbon steel, stainless steel or inconel depending on the specified design life of the system with Kevlar straps also as an option.



The other type of clamp is bundle clamp. It is for small bore service and injection lines that are secured at regular intervals to provide an effective solution to laying subsea lines simultaneously.









These lines will remain on the seabed. Certain cases, pipeline will be buried under the seabed to avoid the external forces that may cause harm to the pipeline. For example, fishing activity, anchor drop and drag from the vessel and etc.
