Subsea production systems Standardized and configurable

• System is configured to field spesific requirements

• Building blocks are standard – but configured as required to meet field requirements, i.e reservoir conditions, seabed conditions and host platform characteristics

Classification: Internal 2013-08-20

System configurations Building blocks Oil production Oil production w/gas lift Gas production Gas injection Water injection Combinations of above

4 slot templates Single slot templates (satellites) Wellhead Tubing Hanger Xmas Tree Choke Module Manifold Production Control System Tie-in tool (normally rented)

Standard universal workover system

• For well completion and workover

• Can be used on subsea trees from both Aker and FMC – in future also GE and OneSubsea

• First contract won by Aker

• Equipment for 5 parallell rig operations being delivered and taken into use late 2013 / 2014

Classification: Internal 2013-08-20 1

Umbilical – standards for static and dynamic applications

First tender won by Nexans – call-offs up to 50 km total

Leading in seismic imaging and interpretation to increase discovery and recovery Contribute to add quality prospects in areas with complex geology

Become a leading exploration company

Pushing reservoir characterisation and recovery to the next level to maximise value Enable faster maturation of resources & reserves

Contribute to add 1.5 bn boe to reserves by 2020

Step change in well-construction efficiency to drill more cost-efficient wells 30% reduction in well construction time and 15% in well construction cost by 2020

Taking subsea longer, deeper and colder to accelerate and increase production Simplification and standardisation Flexible Subsea tie-backs Realise subsea compression by 2015 and complete subsea factory by 2020.
