By 16 februari 2013Geen categorie, Our Projects

DCN and Nigerian partner ADS have been awarded the saturation diving contract for the NPDC – Okpoho-Okono 16” Pipeline Replacement Project in Nigeria, by contractor West African Ventures.

Work was executed with the DPII Lewek Toucan and started in May 2013. DCN was contracted by WAS Nigeria to conduct the following scope at 70msw:

  1. Subsea spool and mattress installation
  2. Pipe lay support to JASCON 30
  3. Disconnect and Re-Connect A/R Wire for Barge to pull off site
  4. Removal of Laydown Head
  5. Closing spool metrology
  6. Prepare target box – mattress laying

During this project, The Jascon 4 tug capsized on May 26, 2013 off the coast of Nigeria with only one survivor from 12 people on board. Now, six months on from the accident, incredible footage has emerged showing the moment the ship’s cook was rescued from an air bubble on the ship, two days after the ship capsized. From 20 seconds a member of the DCN Diving rescue team exclaims as the sole survivor’s hand comes into view, Okene Harrison was visibly shaken, but alive.
