14 OPPSUMMERING : Oppsummering : De vanskelige fatene gjennstår å få produsert. Snorre Expansion Project vil bidra med betydelige ekstra volumer og aktivitet i bransjen hvis realisert Subsealøsning «mer enn subsea» Prosjektøkoniomien enda en utfordring. Forenkling, standardisering, industralisering og sammarbeid på tvers i bransjen viktig for å få til en nødvendig varig endring i kostnadsnivå.
