Video shot on board pipelaying vessel Lewek Champion. Showing the process of laying sub sea pipeline in what is known as S lay techique. It follows one piece of pipe all the way from the deck to the sea. I did not make this video, This video is posted on behalf of the owner.

Witness the technological marvel of laying pipelines on the ocean floor. The ONGC S1 Vasishta project in the country's Eastern Offshore is in its commissioning stages and gas pipeline connectivity is a crucial cog in the entire chain.
#2016# CPW successfully delivered pipes to Wintershall for the Maria offshore project in the Norwegian sea. The reel lay project is a water injection pipeline and the laying contractor is Subsea 7. 50Km of 12” 17.5mm DNV HFW 450 pipes were produced from state of the art 26” HFI pipe mill in Thisvi, Greece and were reeled in SS7 Vigra spoolbase. Worth mentioning are • the enhanced dimensional tolerances for better fit-up and • the pipe length of up to 24m compared to the usual 12m which meant less girth welds, decreased preparation time and lower total cost. #Under licence of Wintershall

TAP's crossing of the Adriatic Sea is projected along the shortest-possible distance between Fier, in Albania and Italy's southern Puglia region, while taking into account environment protection requirements and the specifics of the Adriatic seabed. Laying the steel pipes at depths of more than 800 meters will allow developers use of S-type lay barges, a state-of-the-art technology widely used in pipeline construction. Explaining offshore pipe-laying technique: The offshore pipeline will be laid from a special vessel, the so-called S-type barge. Joints of 12-metre-long pipe will be welded to the pipeline string on the deck of the barge. The vessel is then moved forward, while the pipe string gets laid to its rear into the water and follows a S-shaped curvature to the seabed. Special eq...
A short video presentation of offshore pipeline installation steps.
This video was presented the first time by Jan Buijvoets on the deep and ultra deep water pipeline conference in London, organized by IBC energy on May 22nd and 23rd 2012. O-lay is originally designed for the development of small offshore oil and gas fields With this concept we show the possibility to use the O-lay installation technology to install Pipe in Pipe (PIP) in ultra deep water. The pipeline which is welded onshore and bend only in its elastic area will keep its original roundness during installation. With the O-lay technology it is possible to use concrete coated pipeline due to the fact that a concrete coating will remain in its elastic form and will not crack or break during the bending applied during the O-lay installation.
