Nexans has been awarded a Eur 50 million contract by Dolphin Energy to manufacture and install the chemical injection/control umbilicals for the Dolphin Gas project in the Middle East.
Nexans has been awarded a Eur 50 million contract by Dolphin Energy to manufacture and install the chemical injection/control umbilicals for the Dolphin Gas project in the Middle East.
The two Nexans umbilicals, with respective lengths of 90 and 75km, will link two offshore platforms to the Dolphin Ras Laffan processing plant in Qatar.
They will supply corrosion inhibitor, hydrate inhibitor and diesel fuel to the two platforms, as well as facilitating communication via a fibre-optic element.
Dolphin Energy's Dolphin Gas Project is one of the largest single energy initiatives ever undertaken in the Middle East.
Dolphin gas will be a unique source of clean new energy for the Southern Gulf.
Through its supply of natural gas from Qatar, the Dolphin Project will also bring together three GCC nations - the UAE, Qatar and Oman - in a regional energy network for the very first time.
Initial flow, when the project is commissioned in 2006, will be an average of two billion standard cubic feet per day.
Manufacturing the umbilicals will require 684km of super duplex steel tubes, and 165km fibre optic element.
The tubes will be welded into continuous tube-strings in Nexans' cable and umbilical factory in Halden, Norway.
The fibre optic element will be manufactured at the Nexans factory in Rognan in the North of Norway with the final assembly and sheathing carried out in Halden.
When the umbilicals are completed, they will have a total weight of almost 3000 tonnes.
Manufacture of the umbilicals is planned for completion in early 2006, ready for installation offshore Qatar in the summer.
At the shore end, the two umbilicals will be buried in a trench to provide protection for a length of over 1km from the beach up to the connection point.
Nexans has considerable experience in "shore-to-offshore" applications including prestigious projects such as Scarab/Saffron, Corrib, Snohvit and Ormen Lange.
