Howden Supporting Floating Production System

Screw compressors aid vapor recovery

A Gulf of Mexico-based floating production system (FPS) is receiving support in waste vapor recovery from Howden.

Oil and Gas Company LLOG Exploration, along with Audubon Engineering Company, is refurbishing a former production facility. The resulting Salamanca FPS is the first of its kind in the Gulf. The facility, partially submerged in 6,400 feet of water, will be capable of producing 60,000 barrels of oil per day and 40 million cubic feet of natural gas per day. Initial production is slated for mid-2025.


One of Howden’s machines will support the Salamanca with gas compression by collecting vapors that would otherwise be released into the environment. The vapor recovery unit (VRU) arrangement is highly efficient, complying with API Standard 619; the 510 machine feeds the 255 compressors in series. The variable drive motor contributes to operational and energy efficiency.
