The Ramform Tethys is currently working on her maiden project, a multi-client survey over the Aasta Hansteen area of the Norwegian Sea, with a configuration of 16 streamers, each 8.1km long, with streamer separation of 75m.
On Aasta Hansteen, Ramform Tethys is recording high-density 3D broadband seismic data from the largest amount of streamer ever towed behind a single vessel. The total spread tots up to 129.6km of GeoStreamer equipment.
The Ramform Tethys thereby exceeds the previous industry record, which was set by sister ship the Ramform Titan, in December 2015, for towing around 127km of GeoStreamer during the first ever 18-streamer deployment in the Bay of Bengal. She, in turn, took the lead from Ramform Sovereign.
“I continue to be impressed by the ability of PGS crews to utilize the Titan-class vessels, as demonstrated by Ramform Tethys and her crew on Aasta Hansteen. The performance we see from competent crews and remarkable vessels is a great asset in a challenging market,” Arild Reksnes, PGS EVP operations said.
Ramform Tethys commenced acquisition in June of a new 4400sq km 3D GeoStreamer survey over the Aasta Hansteen area of the Norwegian Sea. This survey is due to be completed in August 2016, with fast track data available four months after the final shot.
