Subcommittee 17 Mission

​The API Subcommittee on Subsea Production & Intervention Systems (SC17) provides leadership in the efficient development and maintenance of subsea standards that m​eet the priority needs of the global oil and gas exploration and production industry by minimizing needs for individual company standards, prom​oting broad availability of safe, interchangeable oilfield equipment and materials, and, promoting broad availability of proven engineering and operating practices.

SC17 leadership is committee to promote the standardization process by​

  • Promoting global participation from companies and individuals, with an aim to continuously improve the standards in the SC17 suite.
  • Increasing participation at all levels of SC17 from companies and individuals who have not previously participated in the API standards development process.
  • Maintain balance participation of subject matter experts within three main categories: Operator-User / Manufacturer / General Interest
  • Ensuring a thorough, transparent, and agile standards development process
  • Promote collaboration with other industry standardization organizations to streamline engineering and operating practices​

 Committee Scope

​Subcommittee 17 (SC17) develops and maintains approximately 42 p​ublications within the following subsea production system topics:

  • subsea system,
  • wellhead and christmas tree equipment,
  • flowlines, jumpers and umbilicals,
  • flexible pipe,
  • subsea production control systems,
  • reliability, technical risk, and integrity management,
  • subsea capping stacks/response
  • completion/workover riser systems, and
  • remotely operated vehicles/tools.

Recent development in the topics of:

  • high-pressure high-temperature (HPHT) design guidelines,
  • chemical injection – design, testing, and qualification

You can get further details and scopes of the Series 17 standards in the Exploration and Production section of the API Publications catalog.
