Technical Specification for Subsea Pipeline Connectors and Subsea Jumper Systems
1 Scope
This document specifies the technical requirements for the design, verification of subsea pipeline connectors, as well as the selection, design analysis, prefabrication, assembly, testing, measurement, installation, and retrieval of subsea jumper systems.
This document applies to subsea pipeline connectors and jumpers used in subsea oil and gas production and injection services.

3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
connector system
An actuated connector and other related accessories used to achieve its function.
3.2
jumper
A pipeline connection structure used to tie-in pipeline ends, manifolds, or trees.
3.3
rigid jumper
A jumper constructed using rigid steel pipe.
3.4
flexible jumper
A jumper constructed using flexible pipe.
3.5
multibore connector
A connector with more than one bore for medium transmission. Bores may be concentric, symmetrical, or asymmetrical; internal media may be production and/or injection liquids or gases, hydraulic control fluid, corrosion inhibitors, etc.
3.6
integral connector
A connector that is locked and unlocked by means of an integral, non-removable actuator.
3.7
non-integral connector
A connector that is locked and unlocked by means of an external tool.
3.8
inboard hub
The hub attached to the tree or subsea structure pipe end.
3.9
outboard hub
The hub attached to the jumper or pig launcher/receiver, which mates with the inboard hub.
3.10
primary seal
The seal that acts as the initial barrier (or primary barrier) between the process fluid and the external environment.
3.11
secondary seal
A metal or elastomeric seal located between the inboard and outboard hub bodies, external to the primary seal.
3.12
contingency seal
A spare seal intended to replace the connector's primary metal seal.
3.13
lock
The action or state of fully engaging the connector with the inboard hub and achieving the full preload connection.
3.14
hub face separation
Separation at any circumferential position between the inboard and outboard hub faces caused by internal pressure, external loads, or a combination thereof.
3.15
park
The action of placing the jumper onto a subsea structure in an unconnected state.
3.16
preload
The clamping force applied to two interconnected parts to resist or counteract separation forces caused by internal pressure and/or external loads and bending moments.
3.17
flow induced vibration (FIV)
Vibration of a jumper caused by excitation from the internal fluid flow.
3.18
doghouses
Insulation structures, shaped like a "doghouse," encasing the connector.
