History and Introduction to Draugen

DRAUGEN 1.0

25 March 2014 3

DRAUGEN

25 March 2014 4

Haltenbanken area, 140km North of Kristiansund

Discovered in 1984 and production start 19.10.1993

Partners: A/S Norske Shell (Operator, 44.56%),

Petoro AS (47.88%), Chevron Norge AS (7.56%)

Water Depth ~ 250-280 m

Peak Production 225 000 bbl/day

Continuous project activity and investments underway to make Draugen a high integrity mature producer

Robust and sustainable design; fit-for-purpose for potential future 3rd party Tie- ins

Scope & Technology, 2 Booster Pump Installations (1993, current)

DRAUGEN SUBSEA BOOSTER PUMP 2.0

HELICO-AXIAL PUMPS

The first subsea helico-axial pump installation was at the North Sea Draugen field by Norske Shell in 1993.

More than twenty helico-axial pumps are in operation worldwide, with more than 1,200,000 hours of run time.

WORLD’S FIRST MULTIPHASE SUBSEA PUMP (1993)

Contract Award: 1990 Sales: FMC Kongsberg, Norway Fabrication Pump: Framo, Norway Pump integration: FMC Kongsberg, Norway Host Type: Platform Contract Type: EPC Water Depth: 280 m (920 ft) The Draugen Subsea Well Facilities Contract was the largest subsea EPC contract in Norway at the time. All subsea installations were designed for diverless installation, operation and maintenance. The seabed pumps (i.e. system integration of FRAMO pumps) were the world’s first commercial multi-phase pump installation. The pump was installed in 1993. It ran sucessfully for 12 months (1000 operating hours) and was decomissioned and abandoned due to change in water injection strategy.

Booster Pump Location

DRAUGEN INFILL PROJECT PUMPING SYSTEM

25 March 2014 9

• Reduces back pressure “seen” by wells = increased oil recovery

• Accelerated end-of-field life production

• Avoid continuous gas lift, reduces hydrate formation risk

• Offers metering of new wells coming on stream & expansion flexibility

• Tie-back distance (To Draugen): ~4 km (12” flexible)

• Ambient Temperature (seawater): 6 – 8 °C

• Design temperature (flowlines): 75 °C

• Design pressure: 220 bar

• Number of Pumps: 2

• Motor Rating: 2300 kW

• Maximum dP: 50 bar

PROJECT CHALLENGES 3.0

25 March 2014 14

3 Major Challenges Encountered by the Project and Industry

CHALLENGE 1 - STANDARDS

25 March 2014 15

Description Focus

•Subsea Processing is novel. •>100 specifications (APIs, NORSOK, Draugen Platform Specifications & Shell Standards) •Topside specifications used on subsea processing equipment

•Active engagement with Technical Matter Experts •Early identification of deviations •Standards interpretation (how standards are read)

CHALLENGE 2 - QUALITY

25 March 2014 16

Description Focus

•Limited production capacity of suppliers and subsuppliers •Rework required (value adding?)

•Inspection and Test Plans for major and medium risk components •Define expectation & definition of quality •Focus on finding the right balance in inspection

CHALLENGE 3 - COST

25 March 2014 17

Description Focus

•Large number of specifications and standards are time consuming Stringent requirements for documentation and inspection

Focus on Integrity, Safety, Enviromnent Separate ”must have” from ”nice to have” Cost benefit analysis
