PLEM/PLET

As the oil & gas field development moves further away from existing infrastructures, it often requires a subsea tie-in of the export system with the existing pipeline system. 

Margon Resources specializes in the custom fabrication of pipeline end manifolds (PLEM) and pipeline end termination (PLET) subsea systems and their associated custom fabricated sled.

A PLEM is a subsea structure used to connect rigid pipeline with other subsea structure such as a manifold or a tree, through a jumper. The PLEM has facilities for pig launching and/or receiving. The header is equipped with a ball valve, to isolate the line, allowing recovery of the Pig Launcher / Receiver (PLR). 

A pipeline end termination (PLET), for joining one pipeline valve and one vertical connector.

Both PLEM’s and PLET’s are usually mounted on a flat platform called a sled that is configured specifically for the PLEM/PLET to which it is attached.
