# §250.854. Floating production units equipped with turrets and turret-mounted systems.

- (a) For floating production units equipped with an auto slew system, you must integrate the auto slew control system with your process safety system allowing for automatic shut-in of the production process, including the sources (subsea wells, subsea pumps, etc.) and releasing of the buoy. Your safety system must immediately initiate a process system shut-in according to §§ [250.838](/cfr/30/250.838.md) and [250.839](/cfr/30/250.839.md) and release the buoy to prevent hydrocarbon discharge and damage to the subsea infrastructure when the following are encountered:
  - (1) Your buoy is clamped,
  - (2) Your auto slew mode is activated, and
  - (3) You encounter a ship heading/position failure or an exceedance of the rotational tolerances of the clamped buoy.
- (b) For floating production units equipped with swivel stack arrangements, you must equip the portion of the swivel stack containing hydrocarbons with a leak detection system. Your leak detection system must be tied into your production process surface safety system allowing for automatic shut-in of the system. Upon seal system failure and detection of a hydrocarbon leak, your surface safety system must immediately initiate a process system shut-in according to §§ [250.838](/cfr/30/250.838.md) and [250.839](/cfr/30/250.839.md).
