J. Ray McDermott said it has completed the installation of Dolphin Energy’s two integrated drilling and production platform complexes: DOL1 and DOL2.
 J. Ray’s installation vessel, DB27, completed 16 major lifts, safely installing the decks, bridges, bridge support platforms, and flare towers offshore Qatar.
Offshore hook-up and commissioning will begin this month, and the platforms will be ready for start-up during the summer, to supply natural gas to the UAE and Oman from Qatar’s North Dome field.
“The project presented a number of challenges,” explained Karl Kesser, J. Ray’s project director. “A key challenge was for us to re-package the front-end design for the drilling platform topsides into a series of offshore lifts that were construction friendly.”
J. Ray adopted a vertical split between the utility and process modules in the second week of the project, which allowed the two modules to be assembled in their offshore configuration while still in the fabrication yard.
“This approach allowed us to test all of the module installation aids onshore, and allowed us to complete 99% of all pre-commissioning and nearly 60% of the total project’s commissioning work onshore, which was a great benefit,” said Kesser.
 The modules were split for load out and transportation, and precisely re-assembled at the offshore site in a very smooth operation. J. Ray achieved an impressive safety record during the project, completing over two and a half million man-hours with zero lost time incidents or medical treatment cases.
It was awarded the turnkey engineering, procurement, construction, and installation including hook-up and commissioning of Dolphin Energy Limited’s offshore platforms and associated facilities in December 2003.
