Abstract
A hydrocarbon production field layout comprising a first pipeline (1) with a first inner diameter and a second pipeline (2) with the first inner diameter. A cut off valve (20) with an inner bore with the first diameter, is arranged in a connecting arrangement between an end of the first pipeline (1) and an end of the second pipeline (2). At least one dual main header manifold (3) is in fluid connection with at least one hydrocarbon well (8, 9). A first branch pipe (16, 18) with a first valve (5, 6) is branched off from the first pipeline (1) and a second branch pipe (17, 19) with a second valve (5, 7) is branched off from the second pipeline (2). The branch pipes are connected to the at least one manifold (3, 4).
Claims8
A hydrocarbon production field layout allowing round trip pigging, comprising;
- a first pipeline defining a bore having a first inner diameter;
- a second pipeline defining a bore having an inner diameter equal to the first inner diameter;
- a cut off valve (20) with an inner bore having a third diameter equal to the first diameter, the cut off valve arranged in a connecting arrangement between an end of the first pipeline and an end of the second pipeline;
- at least one dual main bore manifold in fluid connection with at least one hydrocarbon well, the at least one dual main bore manifold defining two main bores having an inner diameter;
- a first branch pipe with a first valve branched off from the first pipeline to the at least one dual main bore manifold, the first branch pipe defining a bore having an inner diameter;
- and
- a second branch pipe with a second valve branched off from the second pipeline to the at least one dual main bore manifold the second branch pipe defining a bore having an inner diameter,
- wherein the respective inner diameters of the two main bores of the at least one dual main bore manifold are smaller than the first inner diameter.
