What is a USV?

A USV is an


There are two types:

  1. Conventional powered vessels which are uncrewed. They have limited time and range at sea and are acoustically noisy.
  2. Renewable energy powered vessels which are uncrewed. They use solar and/or wind and/or wave energy so are persistent and can stay at sea indefinitely only limited by biofouling. Bluebottles are in this category.

Autonomous data gathering and communication platforms

Bluebottle USVs have greater power, payload and performance compared to known competitors and are able to navigate freely and indefinitely across the world’s oceans. Already Ocius is working with two major private-sector partners to develop USVs capable of undertaking specific high value applications in hydrography and defence.

Power & Performance

Other persistent USVs carry only small payloads, have low power for the payload and often have low performance to manoeuvre, avoid collisions and 'make way' out of currents.

Bluebottles harvest all the weather on the ocean; the sun, the wind and the waves so they can advance under all conditions and can remain at sea for months at a time.

Applications for USVs are myriad and measured in the billions of dollars. Major entities in offshore energy, defence and science are investing heavily in uncrewed systems for “dull, dirty or dangerous” operations.

The team at Ocius is focusing all of our experience, networks and love of the sea to create a revolutionary Australian technology for the world’s oceans.
