into multiple sections prior to the pipeline reeling and laying
processes.
Saipem, for example, has engineered and constructed its
latest flagship vessel,
Castorone
, which can perform steep S-lay
in deep waters (
>
2000 m), switching to J-lay mode for ultra-deep
waters (up to and
>
3000 m) or where the project requirements
limit pipe bending and longitudinal stresses. This versatility has
been achieved through numerous distinctive features such as
a dynamic positioning system designed for pipelay and a ramp
system with pipe roller supports, which is fully remote-controlled
without having to abandon the pipe, and capable of attaining a
near-vertical ramp exit angle. Pipelaying capacity is 12 m for triple
joint pipe, 18 m for double joint and pipe size is up to 48 in. (60 in.
including coating).
In order to cater for vessels such as these, the SmartFit
software is now able to simulate, sequence and optimise batches
of double, triple or quad pipe ends to suit project requirements.
For the pipe contractor, this enables pipe ends to be part-welded
into multiple sections onshore, which in turn means less time is
spent welding individual pipe ends onboard the pipelaying vessel.
This can significantly reduce vessel hiring costs and project risk.
SmartFit software is now more intuitive and easier to use,
providing 2D/3D visualisation of pipe ends, which not only
reduces operator error, but also aids the end customer or pipe
contractor’s own understanding of the benefits of using pipe fit up
optimisation software in order to reduce weld cut-outs and delays
to the pipe welding and laying processes.
By utilising 3D visualisation software, SmartFit users can now
visualise the actual sequence of pipe ends onscreen and then
manipulate these, either as single or multiple pipe sections,
in order to obtain the best possible fit up. By using different
onscreen graphs, symbols and colours, the software makes it easier
for users to see the immediate effects of making modifications
to a batch of pipes. For example, users can see instantly how
changing the sequence or rotation of a pipe will affect the overall
project HiLo, the long seam weld restriction or separation for the
project.
Automated reports
SmartFit also provides improved reporting features in various
formats to suit the operator, analyst or pipe contractor. Results
and automated statistical reports can be generated and exported
directly into different formats, including MS Word, MS Excel, .CSV
file, image/graphical reports, as well as more detailed technical
reports that include every pipe joint/HiLo value in a pipeline.
Global impact
New techniques of dimensional metrology, coupled with analysis
and simulation, ensures that the high standards demanded by
pipeline owners can be met by fabrication contractors. OMS
has developed tools and services for virtually all aspects of
dimensional inspection of flowlines and risers. These tools and
services have been vital to a significant number of pipelay projects
over the past five years.
SmartFit is accurate, traceable to national standards, light,
fast to operate and highly portable. The system has been applied
aboard a wide variety of pipelaying vessels and spool bases
around the world.
