MarineNav ROVs for Marine Inspections

MarineNav, located in Montague, Prince Edward Island, Canada, has been showcasing its latest technologies and equipment serving defense, aquaculture, law enforcement and first responder needs in marine operations. The company’s offerings include marine-grade navigation components such as computers and displays; advanced vessel monitoring (AVM) and fleet management systems; and customizable industrial underwater remotely operated vehicles (ROVs).

Interchangeable ROV components
For its ROVs, MarineNav has developed units that are designed to enable quick and easy exchange of interchangeable modular components. The company said that with a range of optional plug-in accessories available, its ROV design is rugged and versatile and that units can be operated by a single person, while interchangeable modules minimize ROV downtime, thereby reducing repair costs. The majority of the company’s ROV components are manufactured in-house at its Montague premises.

MarineNav manufactures a number of ROV product types, including its Oceanus Hybrid ROV System, the Oceanus Hybrid Plus ROV System, the Oceanus Pro ROV System, and the Oceanus Pro Plus ROV System, each with its own particular features and operational advantages, plus a range of Oceanus ROV accessories. The Oceanus Ultimate ROV System will debut in the fall of this year.

The Oceanus Pro ROV from Canadian company MarineNav can be operated by just one person and is designed as a rugged inspection-class ROV capable of operating to a maximum depth of 1000 feet (305 meters) at a maximum speed of six knots for use in propeller, hull and wharf inspections and underwater search and recovery missions.

The Oceanus Hybrid versions were developed as an inspection-class ROV system supplied as a basic and easy-to-use package. Capable of performing underwater search and recovery missions and environmental assessments, the Oceanus Hybrid is also well-suited for propeller, hull and wharf inspections, and, with a weight of only 39 lbs (17.7 kg), is esily operable by one person. The unit features a sunlight-readable, splash-resistant 12-inch (30 cm) display that enables it to be used in any daylight conditions. Its control console is protected by a water-resistant case and the DC power input allows operation in situations where AC power is not available.

The Oceanus Hybrid Plus ROV offers all the features of the Oceanus Hybrid but with the added features of a large 15-inch (38 cm) TFT-active matrix panel on the Topside Control Case, as well as greater flexibility in the choice of attachments that can be added to the unit, thereby increasing functionality and the number of different tasks that the ROV can perform.

New product introductions
MarineNav’s latest ROV product introductions are its Oceanus Pro and Oceanus Pro Plus ROV systems. These units are rugged inspection-class ROVs capable of operating to a maximum depth of 1000 feet (305 meters) at a maximum speed of six knots, making them highly suited for performing not only propeller, hull and wharf inspections but also for carrying out underwater search and recovery missions. The low weight of the Oceanus Pro and Oceanus Pro Plus submersibles of 38.1 lbs (17.3 kg) means that the units can be easily deployed by one person, while the standard features of these units include an ROV housing made of anodized aluminium and an ROV power tether. Optional upgrades include wireless broadcasting in which the operator can enable screen-sharing with other operatives and the MarineNav Fleet Management Suite – this reports the status and health of ROVs remotely to give full tracking of single or multiple units.

The Oceanus Pro Plus includes all the features of the Oceanus Pro as well as the flexibility to customize the system with a range of extra features and attachments, for example the upgrade of the Topside Control Case to an 18.5-inch (47 cm) widescreen version or a 24-inch (60 cm) TFT-active matrix LCD display. The Oeanus Pro Plus is equipped with Full HD 1080P front and back cameras to enable simultaneous viewing and an optional 4K external camera provides even greater functionality.
