The profile of the Ramform with its incomparably wide backdeck is unmistakable. This is the ultimate platform for efficient and safe seismic operations in all conditions and environments.
The delta-shaped Ramform hull was designed by Norwegian naval architect Roar Ramde, and the first seismic Ramform vessel was inspired by the Norwegian naval intelligence vessel Marjata. Its sinusoidal waterline allows stable motion behavior at the beam. The vast backdeck is perfect for installing and towing a large quantity and variety of equipment, and also offers generous interior and instrument room capacity.
PGS acquired the rights to the vessel design with an agreement to build at least six ships. The first, Ramform Explorer, was launched in 1995 and immediately smashed all 3D seismic performance and endurance records.The next generation Ramform Challenger, V-class and S-class ships each changed and expanded on that original design, bringing more power and capacity, breaking new records, increasing safety, reliability, efficiency and with the capability to tow denser spreads, and implement GeoStreamer technology, also data quality.
The Ramform Titan and Ramform Atlas are the first vessels in our fleet designed specifically to fully utilize the potential of GeoStreamer. These are the largest Ramform vessels ever. Each have 24 streamer capacity, and more power, flexibility and safer operations any other 3D seismic vessels.
These Titan-class Ramform vessels are 70m wide at the stern and equipped with 24 reels. They are designed for safe and efficient operations in even the harshest of environments.
Ramform Titan and Ramform Atlas were launched in 2013 and 2014. A further two Titan-class Ramform vessels will be launched in 2016 and 2017.
100% of the PGS fleet is now equipped with GeoStreamer, an implementation process that we started in 2007.
