Overview

This special version of the DVL 500 Compact comes fitted with a Seanet connector, allowing for seamless integration with TechnipFMC's Schilling Robotics work-class ROVs. Nortek has worked closely with TechnipFMC Schilling Robotics to extensively test and integrate this DVL with their ROVs, enabling users to enjoy extended range in a compact package.

The DVL 500 Compact combines the compact design of the standard DVL 1000 with the superior bottom-track range of the DVL 500.

Highlights

Specially equipped with Seanet connector for TechnipFMC's Schilling Robotics ROVs
Bottom-track from 0.1 to 175 m range
Per-ping and per-beam data quality estimates

Usage

Navigation and control for TechnipFMC Schilling Robotics work-class ROVs
Drop-in replacement for existing DVLs with little configuration effort

Integration

Equipped with a Seanet connector, this version of the DVL 500 Compact is designed for seamless integration with TechnipFMC Schilling Robotics ROVs.

Reliability

Tested in demanding conditions in the Oslo fjord, the DVL 500 Compact has a proven track record in areas of variable bathymetry and conditions. The water track feature provides a velocity backup if the bottom becomes out of range. The spectrum analyzer ensures performance.

Results

Effortless setup with dropdown menu initialization significantly reduces integration time, getting jobs up and running faster.
