Ideal for reaching inaccessible areas to grasp and move objects MarineNav offers manipulator arms with options of either single axis or dual axis (with 360° rotation). MarineNav's manipulators provide precise control and are fully compatible with our Oceanus class ROVs. Simple plug and play functionality provide control of manipulators through our topside software user interface.

MarineNav's ROV manipulator is an essential addition increasing functionality to your ROV, providing power and precision to perform gripping and recovery maneuvers to a depth of 300 meters.

MarineNav's on-site design and manufacturing capabilities mean we can accessorize your Oceanus ROV with a custom manipulator system built for your specific needs. Enquire about the following Manipulator options
• Manipulator arm with plier jaw
• Manipulator arm with parallel jaw
• Manipulator arm with closing scoop jaw

Compatible with MarineNav's Hybrid, Pro and Ultimate class series ROV systems the Oceanus ROV Gaff Pole is indispensable when retrieving ghost gear, lost mooring chain or underwater cable.
• Manufactured from aluminum and marine-grade materials.
• Weighs 1.63 kg (3.6 lbs)
• Locking mechanism keeps snagged gear clear of ROV thrusters intake
• Extra long arm with buoyancy chamber offsets weight of snagged gear
• 2-year limited warranty*

Mounting to the float block, MarineNav's Hull Crawler can be used to position the ROV against a vessel's hull or other smooth surface to create a secure connection allowing for greatly improved ease of inspection. This device greatly improves the pilots ability to maintain position and safely navigate a vessel's hull. Contact MarineNav for More Information

Designed by MarineNav and manufactured on-site, the Oceanus Thruster Guard is designed to minimize potential damage that may occur from foreign materials being entangled in the thruster propellers. Constructed with marine-grade materials, the thruster guard is
designed to fit over the thruster assembly without effecting propeller motion, and is locked in place by four threaded bolts and fasteners. Thruster Guards are easily installed requiring a minimum of tools and time.

Sonar systems are ideal attachments allowing increased ROV functionality in low visibility situations. Each class of MarineNav Oceanus ROV system has been designed to operate with a sonar attachment. Check ROV specifications  for compatibility. MarineNav supports many popular brands of third-party accessories. Call MarineNav for more information.

The Gemini 720im fuses Tritech’s Gemini multibeam technology with Tritech’s Micron technology to create the world’s smallest multibeam imaging sonar. 

The Tritech Micron Sonar is the smallest digital CHIRP sonar in the world and is ideal for use by small ROVs, as a first-rate obstacle avoidance sonar in miniature form.  

The Gemini 720ik is a real-time, high-frequency multibeam imaging sonar. Utilising Tritech’s advanced processing electronics, at 1m range the sonar offers a world-class 97Hz update rate to produce high-quality, video-like imagery.

Ultrasonic thickness gauges can be used to measure metal thickness even through coatings. The probe does not need to touch the surface under test, as measurements can be taken through 5 mm (0.2 inch) of water. Readings are not influenced by the probe orientation. 

Underwater searches and surveys often require that the precise position of the ROV be known so that observations can be geo-referenced or the position can be relocated on a future dive. MarineNav supports several acoustic and tether based position tracking systems. 

With all of our ROV systems designed and manufuctured on-site MarineNav is positioned to provide an extensive range of ROV replacement parts that replace ROV modular components over normal wear. Many of MarineNav's replacement parts can easily be replaced in a minimum amount of time and with a minimum number of tools, and MarineNav's service department with knowlegable technicians are available to offer support for specialized ROV part replacement.
