The Hunting vertical surge tank (VST) is a low-pressure vessel designed to store liquid hydrocarbons prior to disposal during both offshore and onshore well testing and clean-up operations.

Positioned downstream of the separator liquid outlet the VST is used to measure liquid flow rates and the combined shrinkage and meter factor. It can also be used as a second stage separator where a longer retention time is required.

A pressure relief valve and a high and low level alarm system prevent overpressurization and over-filling of the vessels during operations. The VST can be manufactured with either a double or single compartment with either a sight glass or magnetic indicators to monitor liquid levels.

The Hunting VST is mounted in a protective frame manufactured according to the requirements of Det Norske Veritas (DNV) 2.7-1 and is designed for vertical operation and horizontal transportation.
