A system for field internally coating a pipe joint comprising a polymer application unit, which has a first cart configured to selectively advance inside a pipe; a first and a second tank configured to contain a first and a second polymer component respectively; a mixer to mix the first and the second component; a first and a second pump to feed the first and the second component respectively from the first and the second tank to the mixer, an applicator to apply the polymer to the pipe; and a conduit comprising a free end configured to be placed near the applicator to feed the polymer from the mixer to the applicator.

System and method for field internally coating a pipe joint

A system for grit blasting an annular junction portion of a pipeline extending along a longitudinal axis on board a laying vessel, comprises at least one carriage configured to advance along an annular path about the pipeline; at least one centrifugal turbine, which is configured to project grit towards the pipeline, rotates about a rotation axis lying on a plane orthogonal to the longitudinal axis and is supported by the carriage; at least one feed device configured to feed the grit to the centrifugal turbine and comprising a hopper which extends along a respective axis, defines a feed chamber and is coupled to the respective carriage and a guide device configured to act in conjunction with the hopper to feed the grit to the centrifugal turbine at all the operating positions of the carriage.
