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 back deck 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. Each new generation of the design, from Ramform Challenger, the V-class and S-class ships to the mightily impressive Titan-class, brought more power and capacity, breaking new records. They increased safety, reliability, and efficiency, towing denser spreads and implementing GeoStreamer technology to improve data quality.
The Ramform Titan-class vessels were designed to fully utilize the potential of GeoStreamer technology. These ultra-high-capacity seismic vessels were built between 2013 and 2017. They are the most powerful design yet, enabling greater flexibility, and securing safer operations than any other 3D seismic vessels.
Ramform Titan, Ramform Atlas, Ramform Tethys, and Ramform Hyperion are 70 meters wide at the stern and equipped with 24 reels, each capable of holding over 10 km of streamlined seismic recording equipment with inbuilt GeoStreamer technology, and positioning units. They are designed for safe and efficient operations in even the harshest of environments.
