SAN ANTONIO, Texas – Sercel has launched its next-generation SeaRay seabed seismic acquisition system at the SEG Annual Meeting in San Antonio.

The SeaRay 428 is a redeployable 4C seabed seismic acquisition system with enhanced productivity and data quality for ocean bottom cable surveys, according to the company.

The SeaRay 428 has three new functions, the in-sea Seabed Line Unit (SBLU) module, a long-range optical extender, and the ability to integrate unmanned recorders from satellite sites over the survey area.

The SBLU offers the capability of 37 km long cables and a doubled increase in the data rate to 16 Mb/s. The optical extender enhances line snaking or long off-set recording, says Sercel.

“SeaRay's new functionalities are also fully compatible with our existing seabed equipment,” said Pascal Rouiller, CEO of Sercel. “This means that the many customers who have placed their trust in the Sercel SeaRay over recent years will be able to take advantage of these upgrades to achieve enhanced seabed acquisition performance.”

The SeaRay 428 can be installed without an ROV and has no battery management requisites, said Alain Tisserand, senior vice president, Marketing and Sales, Sercel. It can function as a real-time monitor and has more channels than before. 6,000 flatpacks = 24,000 channels = 300 km of sensors at 50 m separation, he added.
