Subsea Separation: the elusive history

This database covers all 14 subsea separation projects across the history of the oil industry, going back to the “dawn of subsea” in 1969.


For each example, we tabulate the asset, region, operator, water depth, process technology, Service company, start-up year, power rating, oil capacity, gas capacity, water capacity and some notes.

What is interesting about the data is how elusive the technology’s ascent has been. Two of our projects were cancelled. The largest were 2.3MW. Subsea Boosting and Compression has been 4x more prevalent (chart below).

This matters for the Mero pre-salt field where an unprecedented, giant, 6MW subsea-separation project is being pioneered, to handle high gas and CO2 cuts.
