BP |
2008 |
Verification and assessment of the condition of the
as-installed production and water injection pipelines,
with regards to their lateral buckling behaviour. This
included assessment of mitigation measures to correct/trigger
unformed lateral buckles and assess the effects of, and
solution for, the vertical vibration of the pipelines
at the buckle initiators, due to unexpected transient
changes to the contents density. |
In Amenas
Algeria |
BP |
2008 |
Assessment of the integrity of a laterally buckled 12”
condensate evacuation pipeline installed in the desert
and therefore exposed to severe daily temperature variations. |
Jasmine
North Sea |
ConocoPhillips |
2008 |
Concept design of the lateral buckling mitigation measures
for the HPHT pipeline. As part of the concept design,
different pipeline configuration options were considered,
such as cooling spools with pipeline trenching and backfilling,
shallow burial with intermediate spools and surface snake
lay option. |

2006 |
Detailed analysis of lateral buckling and trawling response
of exposed 16in gas export and 10in infield flowlines.
Developed mitigation measures to ensure strains remain
acceptable, taking account of strain concentration at
field joints. Construction costs minimised by avoidance
of trenching. |

2004 |
Detailed FEA of lateral buckling response for 30in oil
export and 16in WI pipelines. Use of as-laid OOS survey
data to assess likely locations of on-bottom buckles.
Evaluation of various mitigation strategies, including
in-line expansion spools, sleepers and snake-lay.
Final solution was a single additional 30” in-line
spool, with no mitigation required for 16” line. |
