The Rotation Sleeve System-Main Design Features

• Tungsten Carbide inflow sealing technology
• Large inner diameter (3.5) provides no extra
  limits for well maintenance
• Outer diameter 5.8, smaller than any competitor
• Due to compact design, standard interfaces and a
  total length of 5 m, the system is easy to
  install and handle on the rig
• Infinite variable choke positions, rapid valve
  closure (with surface feedback)
• Packer setting feature with surface feedback
• All hydraulic system provides reliable operation
  over the oil well life time
• Test criteria that exceeds Statoil test
  requirements

Qualification of Advanced Well Equipment

• In depth understanding of well completion issues
• Well design can drive design layout
• Complex customers can drive system complexity
• Practical design principles

13
Qualification of Advanced Well Equipment

• Qualification issues need to be considered prior
  to initial system layout and detailed equipment
  design
• Component level
• Unit level
• System level
• How the above levels are interacted needs careful
  planning
• All test stages should be connected up to final
  System test
• Final system test should be carefully planned by
  personnel with relevant test and operational
  background

14
Qualification of Advanced Well Equipment

• Quality is nothing you frame in at the wall,
  quality must have historical and in depth
  accepted rules
• Subcontractors
• ISO 9001
• Proven Traceability record
• Proven Quality record
• Proven delivery
• Qualified according to company standards

15
Qualification of Advanced Well Equipment

• Close co-operation with Oil Companies
• Industry accepted specifications
• Oil companies individual specifications
• Design verification principles
• Practical installation experience

16
Qualification of Advanced Well Equipment

• Co-operation with Rogalandsforskning
• Years of testing experience on related products
• To be involved at an early stage
• Involvements by Veritas
• To verify recommended practice
• Draw on verification principles
• Use as a 3rd party test verification    

17
Quality Program

• FMEA/FMECA (Failure Mode and Effects Analysis)
