Abstract
A pig routing insert or drain is used in various subsea systems having a block structure, e.g., block manifolds, with a plurality of perforated fluid passages. The insert generally includes a substantially unrestricted flow opening configured to allow substantially unrestricted fluid flow and passage of a cleaning pig, and a partially restricted opening having at least one pig blocking structure, in which the partially restricted opening is configured to allow substantially unrestricted fluid flow through the partially restricted opening whilst blocking the passage of the cleaning pig through the partially restricted opening. A method for manufacturing and installing the pig routing insert or drain in a machined block manifold includes positioning a manufactured pig routing insert at an intersection of first and second perforated fluid flow holes formed in a body of a structure and fastening the manufactured pig routing insert within the intersection in the body.
