MARIA PROJECT

Maria Project Map
August 2016, Norwegian Sea
 
CPW successfully delivered pipes to Wintershall for the Norwegian Sea Maria offshore project. 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 at the state of the art 26” HFI pipe mill in Thisvi, Greece, and reeled in the SS7 Vigra spoolbase. The pipeline’s max. depth reached 320m.
 
Notable features of the project:  
 
•             the enhanced dimensional tolerances for better fit-up and
•             the pipe length of up to 24m compared to the 12m used up to now
which meant less girth welds, decreased preparation time and lower total cost.
