can be utilised for the rehabilitation of an existing subsea
pipeline where:
)
)
It is desirable to extend the service life of the
pipeline beyond the period of operation for which it
was originally designed.
)
)
Early loss of integrity, due to operational parameters
such as CO
2
or SRB corrosion that have caused the
pipeline to reach the end of its useful life ahead of
the originally intended schedule. The pipeline may or
may not have at that point, already been shut down
and abandoned for safety and/or environmental
reasons.
)
)
Routine inspection of the pipeline has shown that
greater than anticipated corrosion is taking place and
that unless the corrosion is arrested, the pipeline will
fail at some predictable point in the future, at a time
which is less than the intended design life.

)
In instances where pipelines have been
decommissioned or abandoned due to actually
incurred integrity related issues.
Global expansion
In 2014 and following the successful conclusion of the
IFL development installations in 2013, APS installed
additional IFL into the Petronas subsea pipeline network
in Malaysia, whereby pipelines that were due for
imminent closure have been given a new long-term lease
of life.
Petronas is favouring the option of pipeline
rehabilitation over that of new-lay pipeline replacement
and in so doing will be able to drastically reduce their
offshore operational cost base.
Robert Walter concludes: “During the IFL
development project, we have conducted a detailed
research into potential market for this technology. At
present there are approximately 175 000 km of subsea
pipelines in operation around the globe of which around
20 000 km will become due for replacement in the next
10 years, as these pipelines have reached the end of their
planned service life. These pipelines range in diameter
from 4 - 20 in.
“Based on this enormous potential we have started
to do a soft launch of the IFL technology with the major
offshore oil and gas operators in mainly South-East Asia,
the Middle East, North America and West-Africa and
the response was overwhelming. For the first time in
the history of offshore pipeline operations, there is now
a viable alternative to pipeline replacement, whereby
major anticipated cost savings compared to new lay, are
the main driving factor.
“The IFL system will become globally available in the
first quarter of 2015 and we are market-ready to service
all the major oil companies that have already expressed
their sincere interest in this revolutionary subsea pipeline
rehabilitation system.”
