MarineNav ROV systems are designed and manufactured in Canada. Each system undergoes extensive quality standards and performance tests prior to delivery


MarineNav has applied 15+ years of expertise and experience developing marine displays, computers and software to create the worlds leading inspection-class ROV lineup.

Whether you select an Oceanus Mini, Oceanus Pro, or Oceanus Ultimate ROV system, you purchase a made-in-Canada product designed and manufactured using proven marine-grade materials and superior construction techniques.

All systems are rigorously water tested before delivery, with every MarineNav ROV supported by our Peace of Mind Guarantee and a comprehensive two-year limited warranty. And when needed, dedicated customer support phone lines connect you with on-site ROV specialists who designed and built your Oceanus ROV system.


MarineNav Oceanus ROV platforms consist of four core ROV components; the Oceanus ROV, the Oceanus topside control case, the Oceanus handheld controller and connecting ROV tether. 

MarineNav Designed, Engineered and Manufactured In-House, In Canada
North Atlantic Tough. Trusted Everywhere.

Constant design reviews and system improvements resulted in MarineNav ROVs becoming industry-leading inspection class vehicles. In 2018, MarineNav introduced its first version of the Oceanus class ROV to consumers receiving great initial reviews. Increased year-to-year sales and an ever-growing distribution network have contributed to MarineNav inspection class ROVs being the proven choice of professionals across all marine-sector industries.   

Rigorous testing and feedback from our valued customers have driven our research and development team to develop a remotely operated vehicle that is rugged, durable and competitively priced. MarineNav's ISO 9001 certification and quality management system ensure that each unit we produce adheres to the strictest standards and complies with customer requirements. Each ROV is hand-assembled from marine-grade ROV components, many of which are manufactured on-site.

Rugged and lightweight, ROV core construction of marine-grade machine-milled aluminum
Rugged and lightweight, ROV core construction of marine-grade machine-milled aluminum.

We build all MarineNav ROV systems by hand to strict ISO standards. We use the best quality marine-grade components, and assembling each unit by hand provides our clients with craftsmanship not seen in other ROV systems. Each system undergoes rigorous testing before delivery.

In-house anodizing finish applied to ROV metalwork provides superior protection from corrosion
The In-house anodizing process to ROV metalwork provides superior protection from corrosion.

MarineNav ROVs are built with anodized metalwork to better protect against corrosion and general wear. Our on-site anodizing service ensures all components meet the highest standard of finish.

Carbon fiber infused 3-D printed components created on-site from proprietary CAD design templates
Carbon fibre-infused 3-D printed components created on-site from proprietary CAD design templates.

Carbon fibre components are durable, especially in ice-cold water. Unlike typical plastic ROV components, these can endure drops, dirt, scrapes, and bumps.

3D print technology allows us to manufacture thruster components such as cowlings and props on-site, so replacement parts are always available.

Vectorized thrusters design and powerful engines enable true lateral ROV movement
Vectorized thrusters design and powerful engines enable true lateral ROV movement.

Capable of dynamic ROV motion that includes true lateral, forward, vertical and rotational movement, the vectorized thruster design provides unmatched ROV control and stability, even in strong currents. Increased levels of ROV stability offer users ease of piloting and operation of ROV accessories.

ROV Tether Cable connects the ROV to the Topside Control Case and provides communications, video, and a pair of independent auxiliary conductors for accessory use if available. The tether cable consists of conductors, an aramid strength member, a flotation material, and an outer jacket. Tether strain relief clips constructed from marine-grade metals at all connection points prevent ROV separation and potential damage to the connected tether.

ROV tether manufactured on-site to custom lengths of up to 500 meters. Connect two tether cable segments to a maximum of 450 meters. Connect three cable segments for a maximum of 400 meters.
MarineNav sources tether from a Canadian manufacturer. MarineNav manufactures the male and female tether connecting ends, with the final assembly completed on-site.
