Przekroczenia bezwykopowe HDD pod przeszkodami wodnymi

Wykonawca zaplanował wykorzystanie 3 różnych technologii posadowienia rurociągów: wykopu otwartego, mikrotunelingu oraz sterowanego wiercenia horyzontalnego, w której wykonano 6 największych przekroczeń bezwykopowych pod przeszkodami wodnymi o łącznej długości ponad 3 km. W technologii wykopu otwartego i mikrotunelingu wykorzystano standardowe rury PE-HD WehoPipe o średnicy dn1000x59,3 mm PN 10 SDR 17. W tunelach wykonanych metodą przewiertu horyzontalnego ze względu na bardzo trudne warunki geologiczne i posadowienie na głębokości około 20m, zastosowano rury o pogrubionych ściankach zewnętrznych (dzxe1033,2x75,9 SDR 13,6 MOP 12,5). Rury wyprodukowano i dostarczono na miejsce instalacji w 15-metrowych odcinkach, w celu zminimalizowania ilości zgrzewów na trasie rurociągu.

W grudniu 2006 r. po wykonaniu przewiertów pilotażowych dokonano pierwszego właściwego przewiertu przy Urzędzie Celnym. W otwór pod Odrą wciągnięto 460 i 465-metrowy odcinek rurociągu. Odcinki rurociągu pod Kanałem Parnickim - 360 i 570-metrowy, zostały posadowione w lutym 2007 r. Z uwagi na brak miejsca do montażu rurociągów w okolicy przekroczenia zostały one zgrzane na Wyspie Puckiej a następnie zwodowane i przetransportowane na miejsce wciągania przez holowniki. W przypadku krótszego odcinka całą rurę wyciągnięto z wody i ustawiono na rolkach. Dłuższy odcinek wciągano niemal w całości z kanału. Warto odnotować, że był to pierwszy w Polsce montaż tak dużej rury polietylenowej przetransportowanej i wciągniętej niemal w całości z wody. Posadowienie rurociągów na wysokości Wyspy Puckiej przeprowadzono na przełomie marca i kwietnia 2007 r. Rury o długości 620m i 626 m zainstalowano ustanawiając nowy europejski rekord w długości rurociągu wielkośrednicowego wciąganego do przewiertu HDD.
