In an alliance with Weatherford International Limited, Norson Services was appointed by Technip Offshore UK Limited to provide pre-commissioning services to the Simian, Sienna and Sapphire Development project. This development is in the Egyptian Mediterranean West Delta Deep Marine Fields and will supply the Egyptian LNG export project.
As part of this contract, Norson Services developed a subsea remote flooding module which was able to flood and pig pipelines in water depths of almost 1,000 meters to clean them and allow pressure testing.
Les Graves, Director of Norson's Pipeline, Process and Umbilical division, says: "Newly installed pipelines are laid on the seabed at atmospheric pressure. Our remote flooding module uses the available seawater pressure outside the pipe as a source of power and water to flood and pig the lines whilst still meeting the desired filtration and chemical protection specifications. The benefit of our remote system is that it is ROV friendly and removes the need for connection to a surface vessel, thus saving substantial costs and time.
The success of Norson's remote flooding module opens up new global markets for Norson in areas of deepwater.
Mr. Graves adds: "With oilfield developments moving into even greater water depths, there are now opportunities for Norson which would not have been open to us before Now we have a tried and tested deepwater product which can save clients time and money, we are anticipating significant growth in many deepwater areas."
