Company Introduction - Projects

FPSO conversion ongoing, deepwater technology being developed

� “DeeP Producer 1” (DPP1); Panamax shuttle tanker “Nordic

Laurita”, built Tsuneishi Japan 1981, delivered in July 2006,

dry-docked and classed August 2006, entered Drydocks World

Dubai May 2007 for conversion to Dynamic Positioning FPSO.

Ready for First Oil end 2008/early 2009 pending field specific

items.

� “DeeP Producer 2” (DPP2); Double sided Aframax tanker

“Semakau Spirit”, built Koyo Japan 1988, purchased for

delivery July 2008. Scheduled completion end Q3 2010. Long

lead items secured.

Setting the Scene - The New Deep Water Frontiers

� Deep to ultra deep waters (1000 m down to 3000 m)

� Areas may be prone to hurricanes and typhoons

� No infrastructure

� Challenging reservoir

� Sub-salt

� Heavy oil

� High pressure

� New geological areas

5

Characterized by

Setting the Scene - The New Deep Water Frontiers

� Determine reservoir parameters

� Confirmation of reserves, depletion strategy and full field

development

� High risk level

� Cash flow and schedule of full field development

Setting the Scene - The new Deep Water Frontiers

� Generic designed Dynamic Positioned FPSO’s

The solution offer

� Increased definition of

reservoir parameters

� Minimum lead time

� Independency of infrastructure

� Easily deployable and

redeployable

� Cash flow improvement

Setting the Scene -Why DP ?

� Station keeping by dynamic positioning is independent of water depth

�The deeper the water the more competitive is Dynamic Positioning

�Easily deployable and easily re-deployable to new locations

�Dynamic Positioning systems have proved very favourable in subsea

construction, drilling and shuttle tanker segments

� 20 years successful experience with Seillean DP FPSO in UK and Brazil

Target Areas

10

Generic Design

� To make the DeeP Producer 1 suitable for a variety of fields but still

keep the cost low to allow the concept to be attractive to several

potential clients

Key to success

� To build flexibility into the design but still be able to defer decisions

with significant cost impact related to functions which may not be

required for all field development

Important issues when freezing the Generic Design

� Environmental design criteria

� Topside Facilities

� Process capacity

Dilemma

11

Generic Design - Environmental Criteria

Impact of design criteria

� Selection of conversion candidates

� Size of/number of thrusters and the power plant

� General facility design

� Areas where the DeeP Producer 1 can operate

� Operational uptime

Environment used in generic design

� Structural Integrity based on a Hs 10 meter

� Stay on location in a Hs of minimum 7,5 meter

� Operation in a Hs of minimum 6,0 meter

� Typical current and wind conditions for offshore Brazil, Gulf of Mexico and West

of Africa

12

Generic Design – Environmental Criteria

The selected environmental design criteria

� Allow operation in the majority of the new deep water frontiers

without controlled disconnect due to adverse environmental

conditions

� May result in controlled disconnect in hurricanes and typhoon

areas

� Allow operation in area with harsher environment though multiple

disconnect and a reduced uptime may be experienced

13

Generic Design - Topside Facilities

� Functions incorporated into basic generic design.

� Functions the topside has been prepared for to incorporate.

� Functions not incorporated into the topside or not

prepared for.

To be able to minimize cost, defer important decisions and still

make the vessel flexible, three topside function categories has

been developed

14

Generic Design - Topside Facilities

� Receive well fluid from the inlet manifold.

� Separate oil, gas and water.

� Stabilize and deliver crude oil to storage tanks within

specified standards.

� Condition produced water and dump it to sea.

� Condition produced gas to deliver it as fuel gas to gas

turbines or to the flare.

Functions incorporated into basic generic design.

15

Generic Design - Topside Facilities

� Additional equipment to handle heavy oil

� Variable frequency drivers for electrical submerged pumps

� Gas and water injections

� Subsea chemical injection facility

� Fluid circulation facility

Functions the topside has been prepared to incorporate.

16

Generic Design - Topside Facilities

� Gas compression and export

� Very large GOR ratios

� Design for high content of CO2 and H2S

� High pressure

� Gas to liquid plant

Equipment/functions not incorporated into the topside or

not prepared for

17

Generic Design - Topside Facilities

� The selected strategy will allow the DeeP Producer 1 to

produce from the most deepwater oil reservoirs without

jeopardizing the schedule for the full field development

� The DeeP Producer 1 will not be able to producer from gas

fields without impact on schedule

Topside Facility Conclusion

18

Generic Design - Process capacity

� Number of wells to be tied in and the flow from each well

� Vessel size

� Revenue versus day rate

Selected capacity

� Liquid capacity 60 000 bpd

� Oil capacity 40 000 bpd

� Water production 20 000 bpd

� Gas oil Ratio <1000

Process capacity requirement for an EWT or EP facility is

determined by

DP FPSO – Main Components

� DeeP Producer 1

� The Disconnectable Riser Buoy (DRB™)

� Riser Configuration

� The Dynamic Positioning System

DeeP Producer 1

21

DP FPSO – Full Field Development Configuration

� Design used for stability and global strength calculation

� Gas injection module, two process modules, subsea

chemical injection module and water injection module

23

DP FPSO - Disconnectable Riser Buoy (DRBTM)

� The DRBTM is developed & owned jointly by

FPSOcean & Scana

� An internal turret with an active turning drive

controled by the vessel ICS/heading control.

� A multipath riser connector with built-in ESD ball

valves.

� A 5-path fluid toroid swivel + multipath hydraulic

swivel and electric swivel.

� Quick dis-connect for operational safety

� Dis-connected DRBTM stabilised in ≈40 m below

surface

Key technology element allowing tie-in of multiple risers

DP FPSO - DP System Overview

� Kongsberg Maritime DP control system

to IMO class 2 (DNV DYNPOS AUTR).

� DP system controls four Schottel

azimuth thrusters, existing main engine

with controllable pitch propeller and

rudder and one forward tunnel thruster

� In normal weather conditions (up to 5

meters significant wave height) the

vessel operates with main engine shut

down.

� The DP system is designed to operate in

more than 6 meters Hs , and in more

than 3.5 meters Hs with offloading

tanker in taut hawser mode.

DP FPSO - Propulsion System

� Existing Propulsion System

� Main Engine Mitsui B & W 6L 80

GFC 15800 bhp with

controllable pitch propella

� 1 off bow thruster Rolls Royce

1400 Kw

� New propulsion

� 4 off Schottel Type SRP 4040

LSU FP 3,8 MW azimuth

DP FPSO - Power Generation

� Shaft alt 1 x 1688 KW (existing)

� 2 off Siemens SGT 500 17 MW dual fuel gas turbine generators

� In normal operations, the gas turbines are fired by associated gas

from the produced oil. In case of process or gas compression

shutdown, the gas turbines will switch to MDO within one minute

without loss of power. Heavy fuel oil (HFO) operation is optional.

DP FPSO - Siemens SGT 500

Robust dual fuel Gas Turbine power generation

�Proven design with high availability and

reliability

� Industrial light weight turbine

�Low maintenance and operation cost

�Nominally 5 years between overhauls

�Fuel flexibility
