API BULL 16H, 1st Edition, February 2022 - Automated Safety Instrumented Systems for Onshore Blowout Preventer Actuation

This bulletin provides a review of the equipment and interfaces to be considered for the automation of a blowout preventer to place the well in a safe state in an onshore environment.

This bulletin provides an overview of components that can be considered for future research into developing an automated well control actuation system, such as:

a) top drive;

b) hook load weight indicators;

c) drawworks;

d) mud pumps;

e) blowout preventers (BOPs);

f) BOP control system (closing unit);

g) internal BOP and/or full-opening safety valve;

h) choke manifold;

i) logic solvers;

j) pressure control valve (pilot valve);

k) surface and downhole blowout preventer;

l) pipe tallies;

m) managed pressure drilling equipment;

n) open and closed channel flow meters;

o) pit level sensors.

To the extent that this document reviews specific equipment arrangements, it is recognized that other arrangements can be equally evaluated in addressing well requirements and achieving safety and operational efficiency.
