DEEP7 2017 - Subsea 7 - page 3

The Subsea Integration Alliance with
OneSubsea combines the market-leading
subsea production systems and Subsea
Processing systems with our own SURF
systems, engineering and construction
expertise and Life of Field (LOF) services,
delivering effective alternative solutions
to such challenges as very long tie-back
distances.
Responding to the industry’s focus on
developing affordable internal flowline
corrosion protection, we acquired polymer
lining technology specialist Swagelining
Ltd last year. In addition, we work in close
collaboration and partnerships with a
number of leading suppliers in our industry
to develop and deliver new cost effective
materials to the market.
We are now delivering on a wide range
of technologies, but in this issue of deep 7,
we have highlighted four particularly
significant areas of development. Long-
distance tie-backs are a cost-efficient
alternative to FPSO or platform-based
facilities. Operators are looking for high-
performance flowline heating systems
to enable even longer tie-back distances
to be achieved. To achieve this, we have
developed a unique range of heating
technologies , including an effective
alternative Cold Flow Technology (CFT)
approach (Page 12).
These technologies, either individually
or in smart combination with subsea
processing, deliver significant benefits
to clients. We are enabling more cost-
effective field developments; we allow
existing host facilities to be revitalised; and
we are opening up new, game-changing
operational concepts. The material
and installation costs of pipelines can
represent a significant part of the subsea
infrastructure costs, so we are currently
qualifying high-strength linepipe for
applications in HP/HT and deepwater
application environments (Page 6).
Our Global Pipeline Welding Development
Centre has an outstanding track record
of collaborating with leading pipeline
manufacturers to extend the applications
of lighter, stronger and more cost-efficient
materials. Through its work, we are
delivering significant cost savings in many
challenging subsea applications through
the introduction of new pipeline materials.
We have an even longer history – extending
back almost 40 years – in the design and
onshore prefabrication of our unique
Pipeline Bundles (Page 16).
These self-contained subsea systems
transform the commercial viability
of marginal HP/HT accumulations in
particular, and also open up new business
models offering cost reductions of up to
20% over conventional pipelay methods.
Over 80 Bundles have been installed to date
by Subsea 7 in UK, Norwegian, Dutch and
Australian waters, and we plan to expand
this unique technology on a global basis.
Another key area of strategic technological
innovation has been in Inspection, Repair
and Maintenance (IRM) activities (Page
22). i-Tech Services is drawing on cutting-
edge data management and geographical
information systems to radically increase
maintenance efficiency and introduce
higher-quality decision making for all Life of
Field activities. Developing new technologies
is a very demanding activity for any
company or organisation, requiring focus,
discipline, open-mindedness and creativity.
However, as the examples in these pages
confirm, the successful delivery of a new
technology is one of the most rewarding
experiences in industry. We look forward
to many more, equally satisfying steps on
this long-term journey to which we have
committed.
We continue to have open
engagement with clients
and partners to identify
high-impact industry
challenges, especially for
current and near-future
developments.
Subsea 7 is developing a wide range of technologies.
In this issue of deep 7 we are highlighting four particularly significant areas of development.
