Key technologies – Permanent magnet motor

• High efficiency Synchronous motor performance, 3 x 'air gap' and small diameter PM rotor increase efficiency ~10% liberating surface power for other uses

• High Speed Selections at 5,000rpm with 6,000rpm capability allow for changes in production and GVF

• Sealed Cable wound stator and carbon sleeve rotor allow use of more environmental friendly water-based barrier fluid

• Eliminates subsea moisture control systems because barrier fluid is not part of motor insulation system

• Modular construction allows same motor and unit concept for all pump types

7Direct Drive Systems4/15/2013

Key technologies – Barrier fluid system

• Purpose Protects motor from process fluid Motor cooling Lubrication of seals and bearings

• Features Environmentally friendly barrier fluid

(Water/Glycol) Pure mechanically-based system

• Reduced complexity• No control system delay

Redundant system• Components

Key technologies – Pump hydraulic bundle

• 10 years Experience Sulzerbuilding and installing helico-axial technology for over 10 years

• Tolerant Large axial flow path and clearances tolerate large particles and sand production

• High Speed Compressor-style assembly guarantees machine balance

• Resistant SUME HVOF coatings provide combination of corrosion and erosion resistance

• Thrust Balance piston application in multi-phase flow unique to Sulzer over 10 years

Collaboration

2006 - Sulzer Pumps sanctions R&D activity into subsea pumping

2008 - Joint development agreement with FMC Technologies• Develop a subsea pump module to meet market requirements

• Completion for qualification of first prototype

2012 – FMC Technologies and Sulzer Pumps enter long-term exclusive supply agreement

10

Collaboration – Scope of supply

• Integration into subsea station• Pipe connection• Wet mateable connector• Pump motor unit control system• Drive system including umbilical• High pressure barrier fluid supply unit

• Pump motor unit• ROV panel• Control logic• Penetrator (same make as wet

mateable connector)• Instrumentation attached to pump
