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.

Abstract: A subsea equipment includes two manifolds for fluid import and export from oil wells. The first and second manifolds are arranged in parallel and are interconnected by a jumper. The first manifold includes all equipment for field flow control, such as, for example, selection valves, actuators or robot for remote operations and mandrels for connection to the Christmas trees. The second manifold includes only block valves and mandrels for future interconnection or interconnection to the first manifold.

Abstract: Equipment for connection of subsea pipelines for oil and gas fields includes one machined block manifold having at least one fluid import spindle of side input, one stop valves set provided on a surface of machined block manifold, which also receives a header and branches, a point for line support and device for subsea installation, subsea line or pipeline. This set is installed on a foundation frame in sea soil and will be part of an oil drilling system.

Abstract: A directional gate type block valve includes a valve body, a gate type straddle, a transmission stem and four seats for process fluid sealing, wherein the transmission stem drives the gate type straddle allowing 3 position options for gate type straddle, directing or even completely sealing the system. This directional gate type block valve provides the exploration system the simplification of using only one equipment for directing the process fluid, besides allowing its use in a wide range of permissible working pressures. Other advantages due to its simple geometry are given by the low cost of manufacture, assembly and test of the directional gate type block valve.
