DNV has developed a class notation for seismic vessels in consultation with key industry players, WesternGeco, PGS and Fugro-Geoteam. The need to have enhanced redundancy and proper deck arrangements to ensure continuous operation without loss of speed is the backbone of these new technical requirements. Seismic vessels contain high end computerized technology to find resources below the seabed, and represent a key element in the value chain leading to future offshore field developments. Any interruptions in the ships forward movement can complicate the seismic data processing, and continuous operations with focus to avoid any downtime of key functions are hence of utmost importance.
