Scope and Application

These Guidance Notes provide technical recommendations and guidance on life extension application for subsea production risers attached to FPIs that produce and/or store hydrocarbons. These Guidance Notes outline the riser life extension process that includes inspection and assessment of the riser structure and ancillary equipment for the entire subsea riser system. These Guidance Notes are also applicable to other subsea risers in addition to production risers. The applicable riser types are:

• Production Risers

• Injection Risers

• Import/Export Risers

Drilling risers, workover and completion risers are not covered in the scope of these Guidance Notes.

These Guidance Notes should be used in conjunction with the following two ABS Guides:

• ABS Guide for Building and Classing Subsea Riser Systems

• ABS Guide for Classification and Certification of Subsea Production Systems, Equipment and Components
