As the oil&gas field development move further away from existing subsea infrastructures, it become advantageous to consider a subsea tie-in of their export system with existing deepwater pipeline system offering spare transport capacity. This necessitates incorporating pipeline end manifolds (PLEM’s) at both pipeline ends to tie in the system. 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. It is also called a pipeline end termination (PLET), especially to serve as a support for one pipeline valve and one vertical connector.
