Full title and description

API STANDARD 17G: Design and Manufacture of Subsea Well Intervention Equipment — Third Edition, November 2019. Establishes minimum requirements for the performance, design, materials, fabrication, testing, inspection, marking, handling, storage and shipment of new-build subsea well intervention equipment used in through‑BOP intervention riser systems (TBIRS) and open‑water intervention riser systems (OWIRS).

Abstract

API 17G-2019 specifies technical requirements and acceptance criteria for subsea well intervention equipment whose rated working pressure (RWP) is less than or equal to 103.4 MPa (15,000 psi) and/or rated temperature is less than or equal to 177 °C (350 °F). The standard addresses system and component design (mechanical and structural), material selection, fabrication (hot‑forming and welding), nondestructive examination, pressure testing, documentation and traceability, and manufacturing quality practices. It limits structural design guidance to materials expected to show ductile failure modes (for example carbon steels, low‑alloy steels and corrosion‑resistant alloys) and excludes some equipment types and extreme‑service ratings (refer to API 17TR8 for high‑pressure/high‑temperature guidelines).

Scope

Defines minimum performance, design and manufacturing requirements for subsea well intervention equipment that is connected to a fluid conduit tieback riser (either inside the marine riser — TBIRS — or in open water — OWIRS). The standard applies to new‑build equipment within the stated pressure and temperature limits and addresses mechanical, material, welding and testing requirements. Exclusions include riserless light well intervention systems, downline‑connected intervention tooling, ROV‑only intervention equipment and certain high‑pressure/high‑temperature or non‑ductile material designs (see API 17TR8 and related technical reports for additional guidance).

Key topics and requirements

• Design criteria and performance requirements for TBIRS and OWIRS components.
• Material selection and chemical/mechanical property requirements (focus on materials with ductile failure modes).
• Welding, hot forming and heat‑treatment procedures and qualifications.
• Nondestructive examination (NDE) and inspection methods and acceptance levels.
• Pressure testing, hydrostatic and pneumatic test requirements and protocols.
• Marking, traceability, documentation and manufacturer's data records.
• Handling, storage, packing and shipping provisions to protect subsea equipment.
• Quality assurance, manufacturing controls and supplier requirements.
• Interfaces and compatibility with riser systems and surface/lower marine riser package (LMRP) arrangements.
• References and coordination with API technical reports and other industry codes (NACE, DNV, ASME, etc.).

Typical use and users

Primary users are subsea equipment manufacturers, offshore operators, engineering and design houses, procurement and quality assurance teams, classification societies and test houses. The standard is used to set minimum contractual and manufacturing requirements for intervention lubricators, riser components, connectors and associated pressure‑containing hardware used during subsea well intervention operations.

Related standards

Typical references and related documents include (but are not limited to) API 17D, API technical reports such as API 17TR8 and API 17TR12, NACE MR0175 / ISO 15156, NACE TM0177, DNV recommended practices (e.g., DNVGL‑RP‑C203, DNVGL‑RP‑0034), ASME pressure‑vessel and piping requirements, and other industry welding and NDE standards. Users often apply API 17G together with operator‑specific requirements and classification society rules.

A: API 17G-2019 is an API standard titled "Design and Manufacture of Subsea Well Intervention Equipment" (3rd edition, November 2019) that sets minimum requirements for the design, materials, fabrication, testing and documentation of subsea well intervention equipment used with intervention riser systems.

Q: What does it cover?

A: It covers mechanical and structural design principles, material selection, welding and hot‑forming procedures, nondestructive examination, pressure testing, marking and traceability, handling, storage and shipment for TBIRS and OWIRS equipment within the specified pressure (≤103.4 MPa / 15,000 psi) and temperature (≤177 °C / 350 °F) limits. It excludes certain equipment types and extreme HP/HT cases addressed by other API technical reports.

Q: Who typically uses it?

A: Subsea equipment manufacturers, offshore operators, engineering consultancies, procurement and QA/QC teams, test houses and classification societies use API 17G to develop specifications, purchase orders and manufacturing controls for intervention equipment.

Q: Is it current or superseded?

A: The document published in November 2019 is the 3rd edition. Users should confirm status with API or their standards provider for any amendments, addenda or later revisions before relying on it for new procurements or designs.

Q: Is it part of a series?

A: Yes — API 17G is part of API's suite of subsea and intervention standards and is used alongside API specifications and technical reports (for example API 17D, API 17TR8, API 17TR12) and other industry codes and recommended practices addressing subsea production, intervention and materials compatibility.
