Sub-Atlantic ROV Mohawk

Sub-Atlantic’s fully electric MOHAWK remotely operated vehicle is a small compact, high performance professional ROV system which can be used for a variety of underwater tasks including observation, survey, NDT inspections and tooling.




Mohawk Is a robust, durable and compact ROV system designed for a full range of observation and light intervention tasks,
with plenty open deck space and skid mounted options. The subCAN control system provides advanced diagnostics, precise
vehicle control and reduced reactive maintenance. Thus, the benefit of increased dive time, reduced vessel standby and
operating costs. The system can be supplied as free flying or with Tether Management System.
