Subsea vs Topside
• Most floating production system would required a subsea production
system.
• Most of subsea production systems have a host, majority of these
are floating production units.
• “Subsea to the beach” is a fairly new term, but not widely applied
today. The few examples are Snøhvit and Ormen Lange in the
Norwegian North Sea, both gas fields.
– Snøhvit approx 150 km tie back
– Ormen Lange approx 120 km tie back
• The trend is that an increased number of marginal satellite fields are
tied into already existing topside, i.e. utilize topside to its optimum
capacity to avoid to build new and expensive platforms.

Why Subsea Processing
• Increased recovery
• Accelerate production
• Reduced Capital Expenditure
• Makes it possible to:
–
connect satellite fields to existing infrastructure
–
exploit fields that are normally inaccessible
–
exploit costly infrastructure fully throughout the systems
operational period
–
depressurize system as a hydrate strategy
• Influence on the environment will
decrease
• Reduces water disposal to sea
• Enhances flow management
What influence selection of separation
technology?
• Drivers for subsea processing station
–
System considerations, not only component considerations
–
Flexibility over the life of field, need to cover changes in conditions and uncertainties
• Fluid properties
–
Density, viscosity, mixed viscosity, inversion point etc at operational conditions, asphaltenes,
”schmoo”, creation of foam, emulsions etc.
• Production profile
–
Water cut (WC), gas volume fraction (GVF) as function of time
–
Pressure, temperature profile as function of time
• Sand production
–
During ”normal” conditions and ”worst case” conditions (e.g. screen failure)
• Field layout
–
Field layout of wells/drilling centers/existing infrastructure
–
Sizes of pipelines
–
Location of processing station compared to wells

……to inline, ultra-compact solutions
• Proven topside technology
• Ongoing qualification for subsea use

Subsea pumping
•Multi Phase pump - Helicoaxial or Twin Screw
•Single phase pump - Centrifugal
•Hybrid pump - Helicoaxial + Centrifugal
•Seabed ESP – Horizontal or Vertical
•Applications:
•Single Phase Oil/water
•Single Phase Water Injection
•Single phase Raw Seawater injection
•Multiphase Oil/Water/gas
Sulzer/FMC

Subsea compression
- What are the drivers
• IOR
–
Accelerated production
–
Reservoir depletion – Maintain production
–
Utilize existing infrastructure and extend the
field life time
• Flow assurance
–
Maintain gas velocity to avoid liquid
accumulation in multiphase flow.
• Subsea to beach
–
Compensating pressure drop in transport
system
–
Avoid surface installations
–
Environmental issues as harsh conditions
• CAPEX / OPEX considerations
