Foreword

The advantages of subsea systems have made subsea production a top choice for developments in many environments around the world. Innovations and improvements are being introduced that will increase the reliability and robustness of these systems, which will be used in even more developments over time.

Verification and validation plays an important role in safe and reliable operations of these subsea production systems. This Guide specifies the ABS requirements and process for Certification and Classification of subsea production systems and their associated subsystems, equipment and/or components. An optional class notation CSS ? Production is offered for a subsea production system that has been reviewed, surveyed, installed and commissioned in full compliance with the applicable sections of this Guide.

In addition, Independent third party (I3P) services that can be provided by ABS at different project phases are also described in this Guide. These are customized services based on the request of clients and could include the following:

Design verification (design review) and design validation (survey during manufacturing)

Installation/commissioning verification

In-service examination

Life extension assessment

Decommissioning verification

Certified Verification Agent (CVA) review to meet the government requirements can be provided during design, manufacturing and installation phases for subsea risers. For safety and pollution prevention equipment (SPPE) and subsea equipment in high-pressure high-temperature (HPHT) applications, I3P services for conformance with 30 CFR 250 Subpart H and applicable BSEE requirements can also be provided.

This Guide is to be used in conjunction with other applicable ABS Rules and Guides, codes and standards as referenced therein, and applicable national regulations.

This Guide becomes effective on the first day of the month of publication.

Users are advised to check periodically on the ABS website to verify that this version of this Guide is the most current.

We welcome your feedback. Comments or suggestions can be sent electronically by email to rsd@.
