Thank you to all the stakeholders who participated in the feedback questionnaire for the development of the Subsea Manifold valve specification. Your input will help shape the content and format of the document. The JIP33 Subsea Manifold Valve Work Group developed a supplier questionnaire with the aim to address the varying responses and concerns raised by several subsea system suppliers that requirements are fragmented, additional requirements are needed, and there is justification for standardisation of additional materials and pressure-rated equipment.
The questionnaire was sent to system suppliers and OEM’s, as well as promoted through social media, API, and industry associations such as BVAA to ensure complete transparency. Some Operating Company responses were received but omitted from these results as their official input is provided through the JIP33 Work Group. All responses have been anonymised for confidentiality, and we would like to share the quantitative results and analysis of this.
The results are now available to download and we are using this to help shape the document. As API documents are the normative reference for JIP33 Subsea specification development, we are working with them to understand the best way to review, resolve comments and publish the requirements in 2022.
Manifold Valve Framing & Survey Summary
Four options were considered for the development of a JIP33 subsea manifold valve specification, and opinions on these were sought from the survey participants:
- Manifold valve requirements embedded within S-708 (which is an overlay of API 6DSS);
- Standalone specification for manifold valves only (with API 17D as the main normative reference);
- Standalone specification for pipeline and manifold valves (with API 6DSS and API 17D as the main normative references);
- Supplementary specification to API 17D (standard for design and operation of subsea wellhead and tree equipment).
**Also note that Xmas tree valves are explicitly excluded from any potential scope.
The questionnaire also:
- Surveyed which standards/specs are commonly used to manufacture manifold valves
- Surveyed which standards/specs are commonly used to manufacture ball valves for manifold applications
- The extent of internal and customer specific requirements
- Determined the geographic distribution of sales of the equipment to understand regional differences in markets.
Manifold Valve Framing & Survey Conclusions
- There is a majority desire for creating a combined subsea valve specification
- There is opportunity for 7.5 ksi standard option and possibly12.5 ksi
- There is opportunity for material standardisation
- OEM internal manifold and pipeline requirements have low coverage of Operating Company requirements
- “API 17D with project specific overlay used” in the majority cases
- For ball valves in manifold applications there is a near even split between the application of API 17D and API 6DSS with “project specific requirements”
The International Association of Oil & Gas Producers (IOGP) started Joint Industry Programme (JIP)33 in 2016. Its aim is to develop standardized specifications that enable the industry supply chain to become better, cheaper and faster.
More than 47 specifications have now been published to date and are already delivering benefits for users worldwide, with another 15 specifications currently in development.
