API RP 17N-2009 pdf download.Recommended Practice for Subsea Production System Reliability and Technical Risk Management.
1.1 Project Types The RP is provided as a guide to the whole of the subsea industry and is intended to be applicable to all project scopes including: — repeat field development projects using field proven or fully qualified hardware, — new technology development projects, — field development projects in which existing technology is used under extended operating conditions, — field development projects involving new technology. The philosophy of this RP is to prioritize reliability and technical risk management efforts based on the level and source of technical risk in the project. More detailed reliability effort is recommended for projects/equipment involving high technical risk. For projects/equipment involving low technical risk (e.g. some projects using field proven or fully qualified hardware), little reliability effort beyond existing good engineering and management practices is expected. 1.2 Equipment Types The RP applies to all subsea equipment including the following. — Subsea Equipment and Hardware From the sand face downhole to the top of the riser as defined in API 17A. This would normally also include: downhole and completion components; well systems; topside interfaces; controls; flowlines; pipelines. — Installation Facilities and Tools Risks associated with installation facilities, equipment, tools and procedures should be included to ensure that the construction procedures will not adversely affect the reliability of permanently installed equipment. — System Interfaces Risks posed by hardware interfaces should be addressed, particularly when these interfaces also represent boundaries between different organizations in the supply chain or teams within the project management organization. — Subsea Intervention and Maintenance Workover and intervention methods and tools should be included in the subsea system assessment where these have a direct bearing on subsea system maintainability and availability.
1.4 Qualification Qualification is the process of independently confirming by examination, testing or some other defining evidence, that equipment meets specified requirements for the intended use. The risk of equipment not being fit for purpose or determined as unqualified, is specifically addressed at each project stage within the RP. Users of this specification may have their own processes for qualifying equipment, in which case many of the qualification tasks recommended here may be unnecessary. For projects involving fully qualified equipment and low additional risk, the demands of this RP should be minimal. However, as technical risk is a broad topic, it may not be entirely addressed through a program of qualification testing alone. Even equipment believed to be fully qualified should be considered in terms of broader technical risks in line with this RP to verify that all have been addressed. 2 Other Related Documents 2.1 API Specification Q1 (ISO/TS 29001) API Q1 (ISO/TS 29001) is a fundamental standard used by the subsea oil and gas industry for the achievement of quality in products and services.This RP has been developed to be consistent with the requirements of API Q1. Reliability achievement demands attention to quality in design and manufacture as reliability in design will not be realized if the required quality is not delivered. However, high quality cannot improve the inherent reliability of an unreliable design. Therefore, this RP includes good practices for reliability management (e.g. the setting of goals and requirement, the implementation of system RAM analyses, reliability testing, etc.) which are not generally included in conventional quality assurance (QA) and quality control programs. 2.2 DNV RP A203 and API Recommended Practice 17Q DNV RP A203 and API 17Q recommend that the identification of technical risk and in particular equipment failure modes be used as the basis for determining equipment qualification status.
