Ramform

The profile of the Ramform with its incomparably wide back deck is unmistakable. This is the ultimate platform for efficient and safe seismic operations in all conditions and environments.

The unique Ramform hull shape was designed in Norway and the first seismic Ramform vessel was inspired by the Norwegian naval intelligence vessel Marjata. 

A sinusoidal waterline allows stable motion behavior at the beam, the vast back deck is perfect for installing and towing various equipment and offers generous interior and instrument room capacity. PGS acquired the rights to the unique design based on an agreement to build at least six seismic vessels. We launched Ramform Explorer in 1995, immediately smashed all performance and endurance records for 3D seismic operations.

The Ramform Challenger (1996), V-class (1998) and S-class (2008) each changed and expanded on that original design, bringing more power and capacity, breaking new records, as well as increasing safety, reliability, efficiency and ultimately data quality. 

Titan-class 

The Ramform Titan (2013) and Ramform Atlas (2014) and Ramform Tethys (2016) are designed to fully utilize the potential of GeoStreamer®, including the capacity to record ghost-free data in rougher seas. These are the largest Ramform vessels ever. Each has more towing capacity, more power, and greater flexibility than other 3D seismic vessels. Another new build Titan-class will be launched in 2017.

Ramform Titan-class vessels are 70 m wide at the stern and equipped with 24 streamer reels, with quality and reliability built in at every stage. They are designed for safe and efficient operations in even the harshest of environments. 

These are highly flexible acquisition platforms, that cover all the bases from highly efficient reconnaissance exploration surveys to the detailed resolution required for 4D production seismic.

GeoStreamer rollout

The PGS fleet, both 2D and 3D vessels, is fully equipped with GeoStreamer recording technology. We started the roll out in 2007, immediately after the dual-sensor, broadband technology was introduced
