OS Energy has adopted Sonardyne’s Sprint-Nav DP dynamic positioning (DP) reference system to support its marine renewable energy projects in the North and Baltic Seas. The system enables vessels to maintain DP integrity in shallow water and in environments where Global Navigation Satellite System (GNSS) signals are disrupted, conditions that are increasingly common in offshore wind construction and maintenance.
Sprint-Nav DP is housed in a single pre-calibrated unit. It combines inertial navigation and Doppler velocity log (DVL) technology to deliver accurate seabed-referenced positioning, even if other position reference systems fail.
The Sprint-Nav DP units will be installed on OS Energy’s new offshore survey and service vessels (OSSVs), designed specifically for wind farm operations in the North and Baltic Seas. The DP2 OSSV design incorporates a hybrid powertrain and distribution system capable of operating on zero-emission fuels.
OS Energy has ordered three vessels with options for three more. The first is under construction at Esbjerg Shipyard in Denmark, with delivery scheduled for 2026. Germany-based OS Energy is an offshore service provider with more than 15 years’ experience in wind energy, offering vessel management, survey, inspection and environmental monitoring.
