Van Oord’s Nordnes vessel upgrades to QINSy
After successful installation and acceptance of QINSy on the flexible fallpipe vessel Stornes, Van Oord have invested in additional QINSy licences for another of its rock dumping vessels, the Nordnes. The advanced core technologies of QINSy are the trusted solution for often highly complex, route and time critical, offshore construction projects such as rock dumping. This is a key reason why the vast majority of the rock dumping vessels in the world are using QINSy for positioning the vessel and the fall pipe ROV. Paul Hunt, surveyor at Nordnes puts: "QINSy gives the surveyors on the Nordnes much better presentation of the data and its quality than the previous system. It also gives a wide range of new options and possibilities that the survey team didn't have before".

QINSy allows a myriad of survey sensors to be integrated, plus a comparison of multiple computation results using different positioning sources, and the presentation of the real time georeferenced results of the acquired data. In some case due to the depth of the ROV below the sea level and other external influences, the acoustic positioning can be disrupted resulting in unstable positioning of the fall pipe ROV and consequent interruption of the dumping operation. To minimize downtime, QINSy incorporates sophisticated Kalman algorithms to filter out the inaccurate position updates and deliver a smoothed track of the fall pipe ROV.
