Subsea Systems Intro – Q&A


1. ❓What does the term “Subsea Production System (SPS)” refer to?

✔️ Answer: It refers to all the equipment located on the seabed that helps produce and control oil and gas from underwater wells.

2. ❓What is the main function of the X-Tree?

✔️ Answer: It controls the flow of hydrocarbons from the well and provides connection points for intervention and production equipment.

3. ❓Where does a Manifold get its fluids from?

✔️ Answer: It gathers production from multiple wells and distributes fluids or injection back into the field.

4. ❓What are Jumpers used for in subsea systems?

✔️ Answer: They are short flexible flowlines that connect subsea components such as trees, manifolds, pipelines, or umbilicals.

5. ❓What is the difference between Pipelines and Risers?

✔️ Answer: Pipelines run horizontally on the seabed to transport hydrocarbons, while risers are vertical pipes that take fluids up to the surface facility.

6. ❓What do “PLETs & PLEMs” provide?

✔️ Answer: They provide termination or branching points allowing connection between pipelines, jumpers, or umbilicals.

7. ❓What does the Subsea Distribution System (SDS) mainly distribute?

✔️ Answer: It distributes hydraulic, electrical, and chemical power/signals to subsea equipment to keep them working.

8. ❓What is an Umbilical?

✔️ Answer: A long cable that sends hydraulic, electrical, and chemical fluids from the surface to subsea equipment.

9. ❓What do Flying Leads do?

✔️ Answer: They are flexible cables or hoses that connect distribution units to subsea equipment like trees or manifolds.

10. ❓What does a UTA (Umbilical Termination Assembly) do?

✔️ Answer: It connects the end of the umbilical to other subsea equipment and distributes power/signals through the field.
