  • Where do we stand today with falling demand due to recession?
  • FIRST WE NEED TO UNDERSTAND THE CURRENT ENVIRONMENT. MR ROWLEY HAS EXPLAINED THE MARKET AND THE LARGE DEMAND FOR OIL AND GAS
    THE LARGE DEMAND IN O&G IS DRIVING OPERATORS TO DEEPER WATERS. PROJECTS IN THE REGION OR IN THE 1000M PLUS RANGE.
    NOC’S HAVE 80% OF RESERVES. IOC’S HAVE 20% AND ARE NEEDING TO FIND LARGE RESERVOIRS
    THIS PRESENTATION GIVES AN OVERVIEW OF WHAT IS HAPPENING IN THE SUBSEA INDUSTRY
  • SNOVHIT 160KM
    ORMEN LANGE 180KM
    TARGET DISTANCES
    OIL 200KM
    HEAVY OIL 100KM
    GAS 600KM
    OVER 140 PROSPECTS IN NEXT 10 YEARS ARE HPH1
    15K/35F – 09
    20K/350F – 2012-13
    25-30K/400F – 2014/16
  • ASSOCIATED TECHNOLOGIES IN DEVELOPMENT
    LARGE BORE CONNECTORS
    LARGE BORE WELLS OF TREES
  • <number>
  • RECOVERY LIGHT WELL INTERVENTION
  • Subsea processing systems have been in existence for over 30 years and are now becoming more acceptable to operators
    >$5 billion expected to be spent over next decade
    Trend towards subsea multiphase pumps (over 10 installed) rather than subsea separators (2 installed)
    System availability improved - now industry average (up to 98%)
    Multiphase pumps now considered robust technology and field proven
    Importance of rigorous test programme – as illustrated by Troll Pilot project
    JIPs play an important part of developing this technology
    Norway leads the world in this area of technology with 3 of the 5 leading companies actively involved in the development of subsea processing being Norwegian or based in Norway
