CoroCoro Platform Complex, PDVSA, Venezuela

The first phase of this project involved the fabrication and installation of the wellhead platform. DII fabricated the 1400-ton wellhead deck in our New Iberia yard. Our scope included equipment procurement and pre-commissioning. The 550-ton jacket was fabricated in Venezuela at our Allianza yard, a joint venture with Vhicoa. The platform was installed offshore in the Gulf of Paria.

Subsequent to the drilling program, the CoroCoro production deck, weighing 8,500 tons, was constructed in DII’s jointly owned Alianza yard on the Orinoco River.  DII provided in-country, on-site project and construction management for the duration of the project.

A key element in the project’s success was the use of our heavy-lift tower system which allowed for fabrication and outfitting of large sections at ground level. A unique aspect of the project is the three load-out jetties at the yard, which are required due to the 12 meter seasonal fluctuation in water depth of the Orinoco River.

In addition to fabrication and load out, DII was also responsible for the offshore transportation and installation of the production deck. Installation was performed by Dockwise, using a float-over concept. Our construction barge Caroline was used for construction support and accommodations during the installation, as well as during hook-up and commissioning which was performed by DII.
