WIN WIN - Wind-powered water injection
Assessing a new concept for water injection, utilizing wind power
WIN WIN is a concept for a new generation of oil recovery technology currently being assessed. It
comprises a floating wind turbine which supplies power to a water injection process. The concept is a fully
stand-alone system that includes pumps and basic water treatment. Our ambition is that WIN WIN will reduce
costs, increase flexibility, and reduce emissions.

Renewable and O&G integration
In 2015/2016 assessment
•
Statoils Hywind demonstrator, a floating wind turbine located offshore
Stavanger, Norway, has been operating since 2009. In the record year of
2011 it produced 10.1 GWh.
•
The potential for moving the test unit to the Valemon platform has been
assessed by statoil.
•
Valemon is today supported by power from the Kvitebjørn platform, 10
km away
•
From being able to shut down one of the two gas tubines, a reduction
of 11000 tons of CO2 could be a achieved, with associated costs.

The system

DNV GL © 2016
15 June 2016
The base case configuration and its functionality
1. A standard wind turbine is mounted to a floating foundation.
This foundation also serves as a platform for the water injection system.
2. An electrical micro grid enables controlled start-up and shut-down of the
system, and ensures that power demand matches power supply during
operation. A battery bank ensures power to critical safety and
communication functions during periods of no wind.
3. Communication with the host platform is enabled through satellite
communication. A conventional control umbilical can also be used.
4. The system uses sea water, which is pumped topside using lift pumps.
5. The sea water is filtered down to 50 micron using a vertical disc filter with
backwashing capability.
6. The water is treated with chemicals. Chemicals are stored on board in
vessels, and refilled during other maintenance activities on the platform.
7. Water is injected into the reservoir by injection pumps.

Performance of WIN WIN
 The WIN WIN concept has shown that it can
meet the demands in relation to set
requirements
 Key performance issues addressed in the project
include delivering required injection volumes,
understanding overall availability as well as
investigating start-stop cycles and downtime.
 For the use case considered and others, WIN
WIN exceeds target injection rates over time.
 Injection volumes over time have been simulated
based on realistic wind-data for the use case,
showing that volumes exceed target rate, despite
some periods of low wind.
31

Commercial - CAPEX
 Total CAPEX for the use case configuration with
process equipment located topside comes to around
75 MEUR.
 The wind structure and marine operations and
logistics are the two main CAPEX drivers, together
contributing to more than 50% of CAPEX costs.
 The pump system and development costs are also
significant in the overall investment.
32
DNV GL © 2016
15 June 2016
Commercial - OPEX
 To achieve a realistic estimate of the O&M cost and
performance, DNV GL has modelled the system taking into
account failure rates, repair times and wind and wave data.
 The resulting annual average operation and maintenance
costs are on the order of 4,7 MEUR.
 Key drivers include parts, chemicals, and vessel costs.
 Increased reliability of the system would positively influence
maintenance frequency and scope, in particular for
unscheduled maintenance, reducing operational
expenditures.
33
DNV GL © 2016
15 June 2016
WIN WIN is cost-competitive for suitable fields
 The use case costs have been compared with a
conventional alternative where water injection is
accomplished with a flowline from the host.
 While WIN WIN has higher operational
expenditures compared to a conventional
alternative, the significantly lower capital
expenditure means that it comes out comparable
in 20 year life-cycle comparison.
 WIN WIN is therefore a commercially competitive
alternative in a range of cases, and especially
when host platform capacity is limited or injection
wells are located far away.

An innovation project now entering a second Phase
In the phase 1 of the WIN WIN project a technical and commercial feasibility assessment was conducted with
successful results. DNV GL and its joint industry partners have now started a phase 2 to drive the concept
further towards commercialization by maturing the technical solutions, reducing uncertainty and cost, and
enhancing performance.
Phase 1 - Benefits
Feasible: The concept is, to a large extent, based on commercially
off-the shelf components and systems. Many of the remaining parts
are already undergoing full-scale testing.
Effective: WIN WIN meets performance requirements for a wide
range of injection volumes and several reservoir types.
Competitive: The concept can be cost-competitive, especially
when the host platform capacity is limited or the injection well is
located far away.
Phase 2 - Objectives
The objective for Phase 2 is to develop the WIN WIN concept towards
commercialization. The project will overall on the four following pathways:
Validate: Build confidence and reduce uncertainty in the technical
solution developed in Phase 1
Innovate: Improve performance and competitiveness
Emission: Potential to reduce emissions, reduce carbon tax, from
reduced need of operating gas turbines.
Flexible: The inherent flexibility of the WIN WIN concept means
that more water injection locations can be targeted through easy
relocation, regardless of distance to platform.
Innovative: Building on the strength of two industries, oil and gas
joins forces with wind to achieve something greater together, also
enabling a faster commercialization of floating wind turbine
technology
