The unique Ramform hull shape was originally based upon 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 instrument room capacity. PGS acquired the rights to the vessel design and launched Ramform Explorer in 1995 with 10 streamer reels, immediately smashing all 3D seismic performance and endurance records. Ramform Explorer was upgraded to 12 x GeoStreamer capacity in 2010.
The unmistakable and instantly recognizable profile of the Ramform vessel with its incomparably wide back deck. Ramform represents the ultimate platform for efficient and safe seismic operations in all conditions and environments.
A total of eight Ramform vessels are now in operation around the world, including the Shigen (formerly Ramform Victory) owned and operated by METI in Japan.
The largest Ramform vessels (Ramform Sovereign and Ramform Sterling) each have 22 streamer capacity, and stand head and shoulders above all other 3D seismic vessels.
PGS committed in 2011 to build two Titan-class Ramform vessels that will have a 70 m beam and 24 reel capability, along with many other PGS innovations designed for safe and efficient operations in even the harshest of environments. The first two Titan-class Ramform ships will be launched in 2013 (Ramform Titan and Ramform Atlas). A further two Titan-class Ramform vessels will be launched in 2015.
PGS is in the process of upgrading its full fleet to the GeoStreamer GS platform. More than two-thirds of the PGS fleet now have GeoStreamer capability, with the full fleet upgrade ongoing. The conversion of source array technology to full GeoStreamer GS (GeoStreamer + GeoSource) began in mid-2011.
