Japan’s Mitsubishi Heavy Industries (MHI) has received an order from Norwegian marine seismic and electromagnetic services provider, Petroleum Geo-Services ASA (PGS), for two of its Ramform Titan class vessels.

The vessels, which are the newest generation in the Ramform series, will support PGS’ deep water resource exploration. They feature advanced wide range 3D seismic data acquisition/analysis capability and adopt diesel electric for the main propulsion system to ensure quiet operation.

The 104m long Ramform vessels tows multiple streamer cables from its stern which contain sensors. These detect echoes of sound waves emitted from sound sources and bounced back from the sea bottom and stratum boundaries. The detected echoes are then used for 3D seismic analysis.

PGS ordered the vessels on the back of a previous order for another two Ramform vessels in April 2011. They feature a wider stern compared with existing vessels to allow it to tow up to 24 lines of streamer cables, enabling exploration of a wider area at one time.

The two newly ordered vessels will be delivered to PGS in the first and second quarters of 2015.
