Stornes

On June 27, 2016, the "Stornes" returned to Slovag after 200,000 tons of clean soil has been laid out with special Equipment at the sinking site of "U 864". Also the "Siddis Mariner" was demobilized following the removal of sensors for the measurements that mercury was not swirled up or spread. Now the task of final analysis and completion of final reports remained. According to preliminary environmental studies the operation was carried out without disturbance and spread of mercury. The monitoring during the process was one of the most extensive ever carried out underwater in Norway. The Company Van Oord also used newly developed equipment. The foreship of "U-864" is located on a slope in a geotechnical unstable area. Support of the embankment has now stabilized the area and reduced the risk of backsliding. Further work can now be implemented without imminent danger of landslides and spread of mercury contamination.

Van Oord’s flexible fallpipe vessel, Stornes, has recently been in Damen Shiprepair & Conversion Rotterdam for a scope of work which allows the vessel to operate at greater water depths in future, the company said in its press release. Stornes is a 175m long, 26.24m wide, DP2 vessel used for subsea rock installation to protect piping. Since her delivery to Van Oord in 2011, Stornes has mostly been installing rocks to water depths up to 800 metres. However, a contract awarded to the company in 2013 required the vessel to operate at 1,300 metres. After some minor modifications in 2014, the first phase of the contract was executed. Now, the vessel has received an upgrade to her rock-dumping tower, which enables an even better performance at these water depths. For this, Van Oord chose Damen, as Damen Shiprepair & Conversion Sales Manager Paul Ippel explains: “We have been welcoming vessels from Van Oord for some years now and we received an invitation to tender for the Stornes project in 2014.” Because of this tight coordination of activities, the project has been carried out according to schedule, with the vessel arriving on 6th march and departing 25th may.

Van Oord’s flexible fallpipe vessel Stornes has set a world record. During a period of four weeks, Stornes placed rock in water depths of up to 1,277 metres. The Subsea Rock installation works were executed in relation to the development of the Aasta Hansteen gas field and Polarled pipeline in the Norwegian Sea, the company said in its press release. Recently Van Oord completed the first phase of these record subsea rock installation works, for energy company Statoil. Van Oord will execute the second phase in 2015. Then, rock will be placed after the pipelines and templates have been installed. Subsea Rock installation activities are vital for the stabilisation and protection of offshore pipelines, power cables and other subsea installations.
