Ramform Sovereign

Ramform Sovereign
Ramform Sovereign is one of the most efficient seismic acquisition vessels in operation. Part of the Ramform S-Class, she is equipped for multisensor, broadband acquisition using TGS GeoStreamer® technology and is capable of towing up to 22 streamers.
Designed for endurance and high productivity, Sovereign combines configuration flexibility with a robust and fuel-efficient power plant. Her propulsion and energy systems meet DNV CLEAN standards for low emissions and environmental performance. The vessel features significant built-in redundancy, including dual engine rooms that are fully separated to ensure continued operations in the event of system failure. This design supports stable, high-capacity seismic acquisition across a range of offshore conditions.
