Subsea Manifold

Driscoil Equipment supplies high-performance Subsea Manifolds engineered to control, distribute, combine and isolate production or injection fluids within subsea oil & gas production systems.

Subsea manifolds are typically installed on the seabed and connected to subsea trees, flowlines, umbilicals, pipelines and production systems. They can be configured for oil, gas, water injection, gas injection and other field-specific services.

Main Components

1. Manifold Body

The main pressure-containing structure incorporates the production and injection flow paths and provides connection points for individual wells and export systems.

2. Subsea Valves

High-integrity valves are used to isolate, divert and control flow. Depending on the design, these may include gate valves, ball valves and chokes.

3. Production Headers

Production headers combine fluids from multiple subsea wells before directing them toward the export flowline or riser system.

4. Injection Headers

Injection headers distribute water or gas to selected wells for reservoir pressure maintenance and enhanced recovery.

5. Control Module

The control system provides hydraulic or electro-hydraulic operation of the manifold valves and associated subsea equipment.

6. ROV Interface

ROV panels and tooling interfaces allow operators to perform manual intervention, override or maintenance activities where required.

7. Subsea Structure

A robust structural frame supports the pressure-containing manifold and protects valves, connectors and instrumentation during installation and operation.
