PIPELINE
PIPE LAY
Our personnel is well prepared on facing all the challenges that the operation of pipe laiyng on the seafloor can pose. There are three main ways that subsea pipe is laid: S-lay, J-lay and tow-in.
We are capable of laying all the diameter sizes of PEAD pipe and up to 40 inches steal pipe with our vessels and equipment.
TESTING
Prior to any pipe lay operation, we performe Hydratight-test of all the components installed underwater: flanges, gaskets, bolts, nuts.
After every pipe lay operation we perform the precommissioning test on the entire lenght of the pipe.
SHORE APPROACHING
Once the pipe line reaches the shallow water, special techinques are used to pull it in to the shore:
_Pulling the pipe from the barge with a wire passing through a snatch block installed on the shore
_Pulling the pipe from the shore by means of a winch.
