Project description
Saipem SA is a major contractor to the global offshore industry. In 2011, Saipem ordered a TCP Downline for the pre-commissioning of the Sapinhoá pipeline in Brazil, part of the Guara & Lula field (Brazil). The TCP Downline was used for pressure testing, cleaning and de-watering of the pipeline, pumping methanol, dyed seawater, nitrogen and high pressure air. In total, the TCP Downline completed 45 deployments to 2140 meters water depth. This TCP Downline has set the world depth record for a composite pipe.

Client  (Saipem) reference, September 2013
I am pleased to inform you that Saipem successfully completed the pre-commissioning of the Sapinhoá pipeline. I would like to thank Airborne for their various contributions to the success of this operation;

  • Firstly for designing and manufacturing a lightweight 3” downline, that is rated for ultra-deepwater applications but does not require large handling and deployment systems;
  • Secondly for the continuous and effective support during offshore operations, overcoming all technical issues inherent to the field testing of such a prototype downline.

We, at Saipem, have been particularly impressed by Airborne’s commitment and passion to serve its clients and definitely consider Airborne as a reliable supplier for our future projects.
