Different stages of subsea field development.

A subsea production system refers to the subsea infrastructure that enables oil/gas production from an offshore environment. It consists of a subsea completed well, seabed wellhead, subsea production tree, subsea tie-in to flowline system, and subsea equipment and control facilities to operate the well. It can range in complexity from a single satellite well with a flowline linked to a fixed platform, FPSO (Floating Production, Storage and Offloading), or onshore facilities, to several wells on a template or clustered around a subsea manifold that transfer to a fixed or floating facility or directly to onshore facilities.


As the oil and gas fields move further offshore into deeper water and deeper geological formations in the quest for reserves, the technology of drilling and production has advanced dramatically. Conventional techniques restrict the reservoir characteristics and reserves that can be economically exploited in the deep waters now being explored. The latest subsea technologies have been proven and formed into an engineering system, namely, the subsea production system, which is associated with the overall process and all the equipment involved in drilling, field development, and field operation.

Major components

The subsea production system consists of the following components:

  • Subsea drilling systems;
  • Subsea Christmas trees and wellhead systems;
  • Umbilical and riser systems;
  • Subsea manifolds and jumper systems;
  • Tie-in and flowline systems;
  • Control systems;
  • Subsea installation.
