Moorings Risers

• As we look to deeper water and harsh
  environments we are reaching the current limit of
  mooring and riser technology.

Process Plant

• There is no significant difference of process
  functions on a FPSO to those on a fixed platform.
  The problems can occur due to the motions of the
  FPSO and have to be captured in the design

Conclusions The Future

• Move towards lease/hire contracts
• Current availability might satisfy future
  requirements for shallow water and benign
  environments
• A need for at least 20 new FPSOs
• Reuse Experience Generic design
• FPSOs?
