A system including an additive management system configured to oversee hydrate formation in a hydrocarbon extraction system, the additive management system including a flow meter configured to measure a fluid flow rate, a first sensor configured to measure at least one of a fluid property and an environmental condition, and a chemical injection device configured to inject a hydrate inhibitor into a fluid flow.

Additive management system

A subsea retrievable pressure sensor for measuring fluid pressure at a well or other subsea fluid system. In one embodiment, a pressure sensor assembly includes a subsea pressure housing, a first pressure sensor, an electrical connector, a first hydraulic connector, and a latching mechanism. The first pressure sensor is disposed within the housing, and the electrical connector and first hydraulic connector are disposed in wall of the housing. The electrical connector is electrically coupled to the first pressure sensor to communicate electrical power though the housing to the first pressure sensor and to communicate pressure measurement values from the first pressure sensor through the housing. The first hydraulic connector is hydraulically coupled to the first pressure sensor to communicate hydraulic pressure to the first pressure sensor through the housing. The latching mechanism extends through the housing to secure the housing to a subsea receptacle.
