Unlike conventional survey vessels, C-Worker 5’s design is optimised for its purpose without having to consider human factors. Despite its compact size, the vehicle has excellent sea keeping ability and has been proven to carry out hydrographic operations just as well as a manned survey ship.

C-Worker 5’s inboard diesel engine and sail drive powers a single propeller and can achieve vehicle speeds of up to 10 knots. The vehicle also has the benefit of a shallow draught and excellent maneuverability to enable operations in areas that larger vessels cannot reach.

C-Worker 5 can be launched and recovered by overhead lift with slings and shackles via four integrated lift points.

C-Worker 5 is operated using the ASView control system, which enables pre-programmed missions to be set up, executed and monitored via a graphical user interface. Control modes include waypoint and line following, heading and track hold, station keeping and geofencing. The vehicle can also be operated using a bespoke hand-held remote control unit.

ASView features standard S57 navigational charts with the ability to import files such as geotiff and .dxf survey lines. Situational awareness is provided by a 360-degree camera box on the vehicle’s mast featuring four daylight cameras and one forward-facing thermal (IR) camera. Live video feeds are transmitted to the remote station in real time.

C-Worker 5’s operational safety is enhanced by a SIL1-assured emergency stop system, and a supervision timeout feature that enables the vehicle to perform pre-programmed actions/missions following a loss of communications.

The vehicle’s remote station control equipment is hand-portable and has a small form-factor enabling quick and easy set up to provide a control centre shore-side or on-board a support vessel.

Optional additions to the standard C-Worker 5 package include a docking system for launch and recovery from a mothership, a remotely deployable winch, a COLREG-aware route-planning collision avoidance system, and the provision of tailored operator and maintainer training programmes. L3Harris can also provide bespoke solutions for ongoing technical support and vehicle maintenance.
