It's crucial to control position during pile driving operations. This is especially true with subsea installations. Normally a “bulls eye” type instrument would be used for this application. However, the accuracy and especially the undersea readability (via an ROV) of such an instrument is far from optimal. During pile driving breaks, the potential alternative of reinstalling a gyro was expensive, especially since a specialist survey technician was required. In addition, such a route would have delayed the installation process.
The new digital level gauge (DLG) allows measurement of pitch and roll during and after pile driving operations. The compactness, accuracy, simplicity and re-usability of the new DLG benefited the recent installation of the drilling templates for Nini and Cecilie fields in the North Sea. DONG is operator of the fields, and has partners DENERCO Oil A/S and RWE Dea AG. The DLG was incorporated into the installation program primarily for cost savings, according to the maker of the DLG, Norwich, UK, firm UWG Group.
