The new, fifth generation Ramform series seismic vessels of PGS is built at Mitsubishi Heavy Industries in Japan.

    The order for two seismic vessels plus two options which was signed in Oslo earlier this year.

    When completed in 2013 these vessels will be the most technically advanced seismic vessel featuring 3D seismic data acquisition and analysis capability.

    The vessels will be built to DNV class.

    The new seismic vessels are the first in fifth generation Ramform series, "Ramform W-class". Developed to have length of 104 meter and a very wide breadth of 70 meter, the series adopted diesel electric for the main propulsion system for quiet operation. Based on the design of the current Ramform fleet, capabilities along several key parameters were improved.

    "These new generation series are developed in much bigger size compared to the previous Ramform series. One of the main reasons to develop the new Ramform design in wider hull form was to increase the stability and results of PGS's model tests on these new hull shape prove that these new design give better stability compared to the previous Ramform series," elaborates Johan Tutturen, DNV Country Manager, Japan.
