API STD 17G-ed.3

Annotation of standard text API STD 17G-ed.3 :

API STD 17G, 3rd Edition, November 2019 - Design and Manufacture of Subsea Well Intervention Equipment

API 17G defines a minimum set of requirements for performance, design, materials, testing and inspection, hot forming, welding, marking, handling, storing, and shipping of new build subsea well intervention equipment [through-BOP intervention riser system (TBIRS) and open-water intervention riser system (OWIRS)] as defined herein.

The requirements in this standard apply to equipment whose rated working pressure (RWP) is less than or equal to 103.4 MPa (15,000 psi) or whose rated temperature is less than or equal to 177 °C (350 °F). Equipment ratings that exceed these limits are covered by this document and API 17TR8. For equipment whose ratings exceed the RWP of 103.4 MPa (15,000 psi) or the rated temperature of 177 °C (350 °F), API 17TR8 will take precedence in the event of conflicting requirements with this document.

Structural design methods and criteria given in API 17G are limited to components manufactured from materials that ensure ductile failure modes (e.g. carbon steels, low-alloy steels, and corrosion-resistant alloys). Components manufactured from materials that may not ensure ductile failure modes (e.g. composite materials, titanium, and titanium alloys) are beyond the scope of this standard.

Within this document, the following apply:

• — all tables are normative, unless otherwise stated,
• — all figures are typical and informative in nature,
• — all instances of NOTE and EXAMPLE provide guidance and as such are typical and informative in nature.

The standard covers equipment that is connected to a fluid conduit tieback riser, either inside the marine riser (TBIRS) or open water (OWIRS). Intervention equipment such as riserless light well intervention systems, downline connected equipment, and remotely operated vehicle (ROV) intervention equipment are outside the scope of this standard.
