REPLACEMENT
P
etronas Carigali (PCSB) is the owner and operator
of an extensive network of subsea pipelines that
are situated offshore from mainland Malaysia, in
the South China Seas.
Many of these pipelines run from platform to platform
and platform to onshore facilities over distances of
between several hundred metres to several kilometres, in
varying water depths.
Internal corrosion, due in large part to sulfate reducing
bacteria (SRB), can cause the pipelines to have a relatively
short life cycle that has historically resulted in the
replacement of pipelines becoming necessary within a
time period as short as four years.
Historically, there has not been a viable methodology
that could be utilised to install such a corrosion barrier
to within a subsea pipeline, thus this project for

Project Director and Chairman of

discusses an
innovative liner technology and its
recent deployment offshore.
