Abstract: A flange connection set includes a modified compact flange, having a channel for external-internal seal tests, coupled to a connecting component, and coupled between the compact flange and the connecting component, there is a KX sealing ring with a radius closer to the radius of the conduit. Different types of keys provide the flange connection the ability to withstand high shear and torsional loads without affecting its operation, while also resisting high bending moment loads and preserving the integrity of the sealing ring and the fasteners.

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.

A method of assembly a subsea distribution equipment assembly includes transporting a first block and a second block using a crane of a vessel, aligning and connecting eye joints installed on each of the first and second blocks, connecting a foundation to the first and second blocks using the crane and a trolley, and installing an umbilical termination assembly jumper between the first and second blocks.

Abstract: A subsea separator vessels includes single machined blocks integrated into a hull so as to combine all the valves used in the process of separating the multiphase fluid in the interior of the blocks. The separator vessels have by-pass valves in their blocks, if necessary to interrupt the separation process. The blocks function as a structure for the separating vessels, thereby replacing all of the metal structure necessary to support the tubes and valves of a conventional manifold, thus reducing the total area occupied by the separation station in the seabed.

Abstract: A composite material includes a substrate that is thermochemically treated in order to harden the surface thereof and that is, therefore, not subject to deformations as a result of high stresses sustained by the outer layer. The composite material also includes an adhesion layer overlying the treated layer. Subsequently, an intermediate layer and a DLC (Diamond Like Carbon) layer are added, wherein the DLC layer has a structure based on an amorphous carbon film. The composite material may be used in valves built into submarine equipment. The composite material is thermochemically treated and comprises a treated substrate and an adhesion layer onto which is disposed an intermediate layer that receives a final DLC layer. All of these layers are disposed on the surface of a substrate of a gate valve.

Abstract: A mechanical seal provides bi-directional sealing and comprising a body in hybrid material, being structured in a component of elastomeric material and a component of segmented or non-segmented composite material distributed in a lagged way along said body. The seal is resistant to extrusion failure at high differential pressures, which facilitates its installation in several equipment elements, such as underwater or ground.

Abstract: A metal airtight seal with bidirectional face, self-energizable by pressure, with axisymmetric or non-axisymmetric configuration, has teeth guided at acute angles, both towards the center of the ring and outside, radially. This geometry may provide the airtight seal the characteristic of being self-energizable by fluid pressure and providing bidirectional sealing, both to the internal pressure and to the external pressure. Furthermore, second element of the airtight seal has a course stopper, to limit the deformation of said metal airtight seal. First and third elements of the airtight seal provide the airtight seal high resistance against internal and external pressure, due to the control of radial slacks.

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.

The WCT can be applied to completion systems using completion mode with tubing heads or directly on the wellhead. The modular WCT can be used in oil and gas production well applications or injection of water and/or gases in subsea fields in shallow water to deep water.

Abstract: The present invention deals with the modularization of SDA components, as well as the assembly, installation, and repair thereof. The blocks (10) have a metallic structure (11) and panels (13) that allow the configuration for several equipment, in such a way that both the hydraulic instrumentation and the electrical instrumentation are also modularized. Modularization, according to the present invention, allows the configuration assembly of equipment (40) and (50) on the vessel (85), thus reducing costs in relation to installations of the art. In addition, the equipment is already installed with the umbilicals connected, which allows the modularization to be carried out using the crane (83) of the vessel (85) or even a buoy (95).

In one or more embodiments, the gas from the gas-extraction unit flows from the pump, and is injected directly into the air gap, and thereafter passes via the ejector in order to recirculate the gas to the process line.
