SURF - Subsea Systems

Fairtex provides topsides, subsea (shallow/deepwater), and SURF expertise. We have years of experience with in-depth knowledge of handling simple-to-complex subsea projects. Our company offers a systems-level approach all the way to detailed design engineering.

We have the ability to cover a wide spectrum of subsea complexities and deepwater technologies. We are a quality-driven company that ensures engineering integrity.

• Take a Systems Approach and establish System Engineering requirements.


• Evaluate the Control System requirements - Selection, optimization, testing, installation, and commissioning.


• Direct Hydraulics vs Multiplex (MUX) system selection.


• Subsea Control Module (SCM)-driven systems, functionalities, and control capabilities.


• Master Control Station (MCS) requirements on topside. Interfacing with FPS/FPSO Systems.


• Electrical Power Units (EPU). Hydraulic Power Units (HPU) - Providing water-glycol-based High- & Low-Pressure systems for subsea fluid power.


• TUTA (Topside Umbilical Termination Assemblies).


• Single and Multiphase Flow Meter selection.


• Intelligent Well Controls (IWC) for smart wells and multiple-zone control.


• Surface Controlled Subsea Safety Valve (SCSSV) selection and controls via SCM.


• Develop Hydraulic and Electrical P&ID's, system layouts, single-line diagrams, and schematics.

We also provide Field Development & Architecture philosophies and options to generate Net Value for the following:

Umbilicals:

Most subsea systems require control umbilicals, primarily electro-hydraulic umbilicals. We evaluate the field life and determine if steel tubes or thermoplastic tubes would best suit the project needs. Nexus has been involved in FEED, writing Umbilical Functional Design Specifications, Reviewing Inspection & Test Plans (ITP), Involved in Factory Acceptance Testing (FAT), umbilical commissioning (pre/post umbilical testing).

Risers:

From detail design to procurement, we provide expertise in Risers. Flowlines/Pipelines: Our team has expertise in flowlines/pipelines (onshore/offshore).

Subsea Distribution:

Umbilical termination subsea requires a system of distribution that will provide electrical and hydraulic connectivity. A system of Hydraulic and/or Steel Flying Leads provides this solution. Electrical flying leads provide power and communication to the subsea control module.

Subsea Christmas Trees:

Horizontal and Vertical Trees provide certain advantages. Selection of a Subsea Tree system plays a central role in achieving first oil. Manifold System along with Well Jumpers, Flowlines & Flowline Jumpers, PLETS, and PLEMS; either for Production, Water Injection, or Gas Injection require meticulous engineering.
