Hot Spot-IOGP JIP33 Commences Revision of S-561 Subsea Trees Supplementary to API Specification 17D

What is it?

Following the user feedback review conducted last year, IOGP JIP33 is now starting work on the revision of their specification S-561 Subsea Trees to API Spec 17D following the publication of AP17D 3rd edition in 2021. At this early stage in the process IOGP are inviting input from OEM subsea tree manufacturers only therefore, this Hot Spot is for members’ information only. BVAA members who are subsea valve and actuator manufacturers will be invited to contribute to the revision process at the public enquiry stage later in the year.

The purpose of this specification is to define a minimum common set of supplementary requirements for the procurement of subsea trees to API 17D, for application in the petroleum and natural gas industries. The current 2018 specification can be downloaded for review at S-561, Supplementary Specification to API17D Subsea Trees.

Why is it Important?

The specification is important because it includes supplementary requirements for valves and actuators installed on subsea trees that will be adopted by 12 of the major subsea operators in the oil and gas industry. It is written as an overlay to API 17D following the same structure as the parent standard. It includes specific supplementary requirements for valves, valve blocks and valve actuators, chokes and choke actuators, bleed, test and isolation valves covering design, qualification testing and manufacture.

The BVAA will continue to monitor the progress of this review process and inform members when the public review phase has started which is currently anticipated to be during summer 2022.
