Ramform Atlas
Ramform Atlas is a Titan-class seismic vessel built in 2013 and designed for high-capacity, high-reliability data acquisition. She combines power, redundancy and advanced handling systems to support consistent seismic productivity, even in challenging offshore conditions.
Three variable-pitch propellers deliver 1.8 megawatts of thrust, more than enough to tow her extensive spread of multisensor recording equipment. The propulsion system allows full operations with just two propellers and one engine room, thanks to a fully redundant design with dual, physically separated engine rooms.
The vessel is equipped with 24 streamer reels, including 16 across the main deck and eight in a second row, along with 22 tow points. Six independent source-handling booms enable faster deployment and retrieval, improving safety and making it possible to operate efficiently within tight weather windows. Two stern-launched workboats support streamer maintenance during marginal conditions, reducing downtime and enabling more maintenance to be completed at sea without halting operations.
Ramform Atlas is designed to operate with GeoStreamer® technology and includes steerable sources and streamers, along with automated gear-handling systems that improve flexibility, efficiency and data quality.
