What is a subsea factory?

■ Subsea factory: oil and gas production facilities located directly on the seabed

■ Never sleeps: operates around the clock and throughout the life of the field

■ Producing from declining reservoirs at extended depths

■ No emissions or disposals to sea ■ Safe operation


What is the main benefit of the subsea factory?


Why do we need subsea systems? When traditional platform technology reached its depth limit, subsea wells became the mainstream offshore solution.

Subsea separation provides multiple benefits

■ The well stream may develop slugs, wax or hydrates on its way to the topside.

■ Reduces use of chemicals to re-stabilize the fluid topsides.

■ Subsea water separation and reinjection eliminates produced water spillage to sea.

■ Subsea separation optimize use of existing infrastructure.

Subsea gas compression: an idea in 1985… first application 25 years later

OLSCSt 2009

Subsea compressor/pump station idea: 1985


Subsea gas compression: a technological leap ■ Gas fields require boosting of the

reservoir flow as reservoir pressure depletes

■ Subsea gas compression replaces the need for an offshore platform or onshore compression facility

■ Cost-effective development solution (CAPEX)

■ Reduced operational costs (OPEX)

■ Advantageous to place the compressor close to the well

■ Increased and accelerated production ■ Reducing CO2 emissions through lower

energy consumption ■ No emissions or disposals to sea

■ Safer due to unmanned operation

Some facts and figures

What is the pressure at 10,000ft water depth:

Outside pressure: 4500psi

Inside pressure: 15,000psi @350F Temperature (High pressure high temperature reservoir) (Water from industrial pressure washer: 3,000 psi)

How deep is 10,000 feet ~ 2 miles The factory Weight: 1000T Size: 30m x 50m Power: 12.5 MW

Just in case: Marine Well Containment System ■ Subsea containment and diverter assembly: ■ Water depth: up to 10,000 feet ■ Working pressure: 15,000 psi maximum ■ Containment capacity: 100,000 barrels of liquid and 200 million cubic feet of gas per day
