Requiring a concrete coating to control temperature or buoyancy immediately
increases project cost and is a factor that needs to be carefully controlled.

discusses how to manage the logistics of
concrete coated pipes.
W
ith the increasing challenges faced by the global
oil and gas industry, there is significant pressure
for oil and gas companies to drastically reduce its
cost.
For offshore oil and gas pipelines – that need to be coated
with heavy concrete to control the pipeline’s buoyancy or
pipelines, which requires thermal insulation coatings – the cost
and the complexity of managing such scope becomes a significant
factor that needs to be considered and managed.
In 2013, Wasco was awarded the Polarled project by Statoil
Petroleum AS. The project involved the application of internal
flow coating, anti-corrosion and concrete weight coating for the
482 km of 36 in. dia. subsea gas pipeline. The project scope also
included the manufacturing, supply and installation of anodes. The
pipeline will run from the Asta Hansteen field to the Nyhamna
gas processing facility in southern Norway. This pipeline will be
the first pipeline to take Norway’s gas infrastructure across the
Arctic Circle and will open new gas highway from the Norwegian
Sea to Europe. The pipes will be laid to a maximum water depth
of 1265 m, which will be the deepest pipeline on the Norwegian
continental shelf and the world’s deepest laying operation for a
36 in. dia. pipeline.
In order to address the high complexity of managing the
logistics of concrete coated pipes, Wasco invested in setting up
