About MarineNav
MarineNav is an independently owned Prince Edward Island manufacturer of portable Oceanus remotely operated vehicles, marine-grade computers, displays, vessel monitoring systems and fleet-management software.
Operating context
MarineNav designs and manufactures marine electronics and Oceanus ROV systems in Prince Edward Island. The 2026 Oceanus Ultimate package has eight vectorized thrusters, power over tether, front/rear 1080p cameras and dual-PC topside control. Its depth table lists 400 m standard and 500 m optional, but repeated operations beyond 300 m require upgraded buoyancy; payload accessories have their own limits. DVL enables position hold, while semi-autonomous control is described as a future software update. Tether is sold separately and 4K cameras must be specified at initial build. DND discloses a C$139,469.12 service contract under a standing offer, but the generic Ships and boats description does not identify an Ultimate purchase or confirm delivery acceptance.
