Ramform Titan
Launched in 2013, this is one of the most powerful seismic ships ever and it is fully integrated with GeoStreamer technology and offers high equipment redundancy. Ramform Titan offers fast deployment and recovery of up to 24 steerable streamers plus steerable sources for optimal results.

Ramform Titan
Power, tow density, and redundancy are essential to high-quality seismic data acquisition. Ramform Titan-class vessels deliver all three. Three variable-pitch propellers provide 1.8 megawatts of power, more than enough to tow a wide spread of multisensor recording equipment. Full operations can continue with just two propellers and one of the fully separated twin engine rooms. Two stern-launched workboats enable streamer maintenance, even in marginal weather. Increasingly, both vessel and seismic equipment maintenance can be done at sea without disrupting operations.
Ramform Titan features 24 streamer reels (16 abreast and eight in a second row) and six independent source array handling booms. This configuration supports faster deployment and recovery, greater flexibility, and safer operations, helping crews maximize the operational weather window. Steerable sources and streamers, along with automated gear-handling systems, further enhance efficiency and adaptability. The vessel is well suited for ultra-high-density 3D acquisition and repeatable 4D projects.
Designed to make full use of GeoStreamer® technology, Ramform Titan typically tows 16 streamers and can operate with up to 24 when required.
