Beschreibung
Zusammenfassung:	The invention relates to a pig routing insert or drain used in various subsea systems comprising a block structure, for example, block manifolds, with a plurality of perforated fluid passages. The insert generally comprises a substantially unrestricted flow opening adapted to allow the substantially unrestricted fluid flow and the passage of a cleaning pig, and a partially restricted opening comprising at least one pig blocking structure, in which the partially restricted opening is adapted to allow the substantially unrestricted fluid flow through the partially restricted opening whilst blocking the passage of a cleaning pig through the partially restricted opening. Also disclosed is a new method for manufacturing and installing the pig routing insert or drain in a machined block manifold.
