STRATEGIC FOCUS ON SUSTAINABLE
As part of our strategic focus,
Subsea 7 has adopted a proactive
approach to the Energy Transition.
To achieve this, we use the extensive
experience gained in oil and gas and
renewables projects and apply it to
the design and delivery of new, more
efficient and sustainable offshore
Subsea 7 is committed to supporting
the development of technology to
support the Energy Transition, and
place early engagement together
with one of our corporate values,
Collaboration, at the heart of our efforts.
1: ENERGY HARVESTING SOLUTIONS
energy to supply
power to remote
Subsea 7 has partnered with GEPS
Techno, an engineering company which
develops autonomous hybrid energy
production platforms designed to supply
off-grid marine applications, with a
reliable and renewable power source.
The platform converts wave energy and
solar into electricity.
Following the successful launch of
the WAVEPEARL® low-power platform,
Subsea 7 and GEPS Techno are
currently working together to qualify
the WAVEGEM®, a medium-power
autonomous platform. This platform
generates electricity from a combination
of wave energy harnessed by an
innovative converter, and solar energy
from photovoltaic panels.
The platform is modular in design.
It can accommodate embedded
applications and/or provide power
to external submarine or surface
consumers, harvesting renewable
energy to supply continuous power to
remote systems. For example, powering
a subsea Autonomous Underwater
Vehicle (AUV) docking station to provide
a fully remote survey station; powering a
Subsea Chemical Storage and Injection
Unit to provide a full alternative to
umbilicals; and powering subsea sensors
for environment and wildlife monitoring.
2: ENERGY STORAGE SOLUTIONS
One of the key challenges of the Energy
Transition will be integrating large-scale
renewable energy sources to deliver
a power output that varies over time.
Specifically, the challenge is to address
the gap between intermittent renewable
energy production, and the end-users’

demand for reliable power. The pace of
decarbonisation therefore hinges upon
the development of energy storage
technologies which will deliver clean,
renewable power as a stable and reliable
In 2020, Subsea 7 established a
strategic collaboration with FLASC B.V.,
one of the first movers in the offshore
energy storage space. This collaboration
leverages Subsea 7’s world-class
technical expertise in the development
of offshore subsea solutions and has
culminated in the PowerBundle concept.
The PowerBundle integrates FLASC’s
award-winning Hydro-Pneumatic Energy
Storage (HPES) technology within
Subsea 7’s well-established Pipeline
The result will be a fully integrated
subsea energy storage solution that
delivers stabilised renewable power,
across a range of applications, in an
inherently safe, reliable, and costeffective manner.
ENERGY TRANSPORTATION SOLUTIONS
The transportation of carbon dioxide
and hydrogen will be key to the Energy
Transition but this presents several
challenges that may affect pipeline
Subsea 7 is well positioned to
support our clients in overcoming these
challenges, thanks to an extensive
product portfolio and experience in
handling complex hydrocarbon fluids.
We’re playing our part in key industry
projects and initiatives is this new arena.
4: THERMOPLASTIC COMPOSITE PIPE
Operators are looking for proven Energy
Transition technology solutions that meet
their high standards for sustainability
while keeping CAPEX investment low.
The development of Thermoplastic
Composite Pipe (TCP) in free hanging
riser configurations offers opportunities
– so much so that Subsea 7 has
recently made a strategic investment in
the leading TCP manufacturer, Strohm,
based in the Netherlands.
Strohm’s TCP is a strong, flexible,
non-corrosive, and spoolable pipe
technology, with a proven track record
and more than 25 years’ design life. It
offers up to 60% reduced CO2 footprint
compared to steel pipeline alternatives.
Its non-metallic nature makes it
immune to hydrogen embrittlement.
TCP is also insensitive to pressure
cycling from power fluctuations, thanks
to excellent fatigue resistance. The long
design life of the product (approx. 25+
years) and its resistance to degradation
allows operators to produce hydrogen
reliably, and without the need for
inspection and maintenance.
TCP’s total elimination of any
corrosion, its long design life and ability
to be pulled through old pipelines make
the technology equally beneficial for
3: HISTORIC NORTHERN LIGHTS PROJECT
Subsea 7 is proud to be part of the
pioneering Northern Lights project.
Northern Lights is Norway’s first
licence for CO₂ storage and a major
part of the initiative that the Norwegian
government calls “Longship”. This
full-scale carbon capture and storage
(CCS) project comprises transportation,
receipt and permanent storage of CO2 in
a reservoir in the Norwegian Continental
Subsea 7’s scope includes
engineering, fabrication and installation
of a 100km CO2 pipeline running from
Øygarden to the CO2 storage complex,
as well as installation of umbilicals, tieins and pre-commissioning activities.
