Recommended Practice on Subsea Production System Reliability, Technical Risk, and Integrity Management (includes Addendum 1 dated May 2018) Provides a structured approach that organizations can adopt to manage uncertainty throughout the life of a project. This may range from the management of general project risk thr ough to the identification and removal of potential failure modes in particular equipment. This recommended practice aims to provide operators, contractors, and suppliers with guidance in the applicati on of reliability techniques to subsea projects within their scope of work and supply only. It is applicable to standard and nonstandard eq uipment, and all phases of projects, from feasibility studie s to operation. It does not prescribe the use of any sp ecific equipment or limit the use of any existing installed equipment or recommend any action, beyond good engineering practice, where current reliability is judged to be acceptable. It is also not intended to re place individual company processes, procedures, document nomenclature, or numbering; it is a guide. However, this recommended practice may be used to enhance existing processes, if deemed appropriate. Most organizations will find much that is familiar and recognized as good practice. Some annex sections may only be of interest to a reliability specialist. The basic approach, however, is simple and consistent, and when applied correctly, has the potential to greatly reduce the fi cial risk of designing, manufacturing, installing, and operating subsea equipment
