CNS trenching machines
are fully hydraulic powered
and able to bury under water
pipelines from 2,5 m up
to 100 m water depth.
Thanks
to their great flexibility,
the machines can be configured
in oreder to face the burial
of pipelines ranging from
4" to 48" diameter, a trench
depth up to 2,5 m in a single
pass and 5 m depth by multiple
passes.
The systems are
designed with the aim of
avoiding any type of damage
to pipelines to be buried
by means of either active
and passive pipe protection
arrangements.
PIPELINE

C.N.S. performs pigging
& digging hydrostatic,
pressure test of on-shore
and off-shore pipelines.
The test medium may be sea
