Oil and gas industry Underwater production system design and operation Part 15. Underwater structures and manifolds

1 Scope

GB/T 21412 of this part of the recognized and widely accepted within the framework of industrial norms and standards, put forward the underwater structure and manifold push Recommended practice. Therefore, it does not replace or exclude any requirement of other industry regulations.

This section applies to underwater oil and gas production and underwater injection pressure control of underwater manifolds and base plate. See examples of underwater production systems figure 1.

This section covers the following equipment.

a) Underwater production system structural components and piping systems.

--- Production and injection manifold;

--- Modular and integrated single satellite wells and multi-well base plate;

--- Underwater treatment and underwater booster station;

--- Oil (gas) riser base and the outer riser base (FRB, ERB);

--- Pipeline terminal manifold (PLEM);

--- Pipeline terminal (PLET);

--- T-type and Y-type connection;

--- Underwater isolation valve structure (SSIV).

b) underwater production system components.

--- Underwater control and distribution structure;

--- Other underwater structures.

c) Protective structures associated with the above equipment.

The following parts and their applications are beyond the scope of this section.

--- Pipe and manifold valves;

--- pipes and connectors;

--- Grease mouth;

--- Production control system.

General information related to the above may be obtained from other specifications such as 13628-1 and APISpec2C.
