Key Highlights:
- Vessel design priorities have remained consistent: Wide-azimuth towing capacity, stability and system redundancy continue to underpin efficient seismic acquisition, particularly in deepwater and frontier environments.
- Performance metrics have evolved beyond production rates: Operational efficiency is increasingly measured by uptime, repeatability, safety and emissions intensity per survey area, reflecting a more integrated view of acquisition outcomes.
- Large-scale case studies highlight operational realities: Frontier campaigns such as the Brazil Equatorial Margin 3D survey demonstrate the importance of sustained vessel performance, consistent geometry control and data quality in complex, high-cost exploration settings.
TGS' Ramform Tethys vessel performs offshore seismic operations.
