Containment and Integrity The main service/criterion for a transport system is containment. Failure of the
transportation systems are identified by
- leak- rupture/burst- collapse
Technical integrity is also the primary concern in the standard for subsea systems, but operational integrity is taken into consideration where this is essential for the system (e.g. umbilical, control system, etc.)

Reassessment
Condition assessment
Provide information on assuring confidence in the system and on actions that need to be taken to achieve the objective of life extension with respect to the acceptable level of risk.

DefinisjonerDesign life
The design life is the specified period for which the integrity of the system is documented in the original design with anticipated maintenance, but withoutrequiring substantial repair.
Service Life
The time length the system is intended to operate. The service life is a part of theapplication toward authorities.

Life Extension Premises Authority regulations
- The latest authority regulations apply to the transportation system
Design Standards- Gaps shall be assessed toward latest standards and the risk shall be assessed
Design Premise- Describes the operational and design limits for the system, e.g. operational pressure
Threats to the transportation system may cause- Leak/ Rupture/ Collapse
System Overview- Battery limit is from pig trap to pig trap, but other may apply- Interact with multiple other systems along the transport route
