Teledyne Marine unveils first model of new deep-water multibeam range

Teledyne Marine has expanded its product portfolio with the introduction of the SeaBat D100, the first model in the newly launched D Series deep-water multibeam line. The release marks the company's latest move to address growing demand for high-performance subsea survey technology, combining the established reliability of the SeaBat brand with a compact, adaptable design built for deep-water applications.

Engineered for surface vessels operating in water depths down to 3,000 metres, the D Series prioritizes portability without compromising performance. Its smallest configuration supports deployment on vessels of opportunity and unmanned surface vessels, broadening its appeal beyond the dedicated survey ships typically associated with deep-water multibeam systems. The SeaBat D100's compact sonar head and topside processor reduce the infrastructure burden traditionally tied to deep-water operations.

Pole mounting

Where deep-water multibeam systems have traditionally demanded significant vessel infrastructure, the SeaBat D100 takes a different approach. Its compact footprint supports pole mounting, making multi-vessel operations and rapid mobilizations far more practical. Installation-optimized cabling comes as standard, and an optional mounting bracket helps teams get up and running with minimal downtime.

The performance credentials are equally compelling. Beam stabilization technology keeps swath coverage consistent even as conditions change, while resolution remains reliable across the full depth range. Multi-ping capability adds further efficiency by boosting along-track density and coverage rates, reducing ship time in the process. A refreshed user interface completes the picture, streamlining operations from first deployment onward.

“The D Series represents a significant evolution in our deep water offering," said Pim Kuus, senior hydrographer and product manager of instruments & imaging at Teledyne Marine. “With the SeaBat D100, we are delivering the high-resolution performance our customers expect from SeaBat, but in a compact and deployment-flexible form factor. It enables true deep-water capability from vessels that previously could not accommodate traditional systems."
