Sonardyne Ranger 2 for Pioneering Spirit

Posted by Irina Tabakina

Sonardyne’s Ranger 2 Ultra-Short Baseline (USBL) acoustic positioning system was selected by Allseas Group for the world’s largest pipelay and platform installation/decommissioning vessel, Pioneering Spirit, which was built by Daewoo Heavy Industries and measures 382 x 124m. Pioneering Spirit was named a “Great Ship of 2014” by Maritime Reporter & Engineering News, sister publication to MTR. The vessel is designed to be able to lift loads of 48,000 metric tons and has sufficient deck space to deliver or remove a complete topside module and jacket in one trip. The Ranger 2 USBL system will be used as a high precision independent acoustic reference for the vessel’s Kongsberg dynamic positioning (DP) system during structure installation or pipelay operations when maintaining a steady position is a critical requirement.
