  3. BATHY conducts its first bathymetry trials.

    Bluebottle BATHY is a result of ‘lessons learnt’ from the bathymetric mission we performed earlier this year with renewable energy powered BEACON off Japan. Trials off Freemantle were successful, but off Japan, in less-than-ideal conditions, BEACON struggled.

    Bathymetric work requires a vessel to i) power the underwater sensors, ii) drag the underwater sensors through the water, iii) keep highly accurate lines in a ‘mow the lawn’ pattern iv) keep very high bandwidth communications in real-time back to base.

She looks just like a regular Bluebottle, but she has some significant differences: in the mid compartment she has a 5kW genset, in the keel 400litres of diesel, on the transom a sound velocity transducer and on the bow, a Starlink high bandwidth satellite unit.

    Ocius partnered with Seismic Asia Pacific ( to conduct MBES trials off Sydney with. Seismic Asia Pacific provided a Norbit i80 and Norbit B57 MBES winghead to conduct these trials with, which Bathy did with excellent results. Part of the hydrographer’s trial report was: “The system proved this ability in adverse weather conditions at the approaches to Botany Bay. Typically, with a displacement hull in adverse sea conditions, a major issue affecting survey quality is aeration or ‘bubble sweep’ over the face of the transducer. During the sea trials no aeration was observed over the transducer, indicating that the keel mounting is sufficiently deep and the vessels sea-keeping characteristics cause minimal aeration at the transducer.”

  4. BB705 goes to Canberra.

    This year, Ocius was a Bronze sponsor of the Australian Industry Defence Network (AIDN) Expo at Parliament House Canberra on 27 November. Bluebottle 705 was showcased on the lawn of Parliament House.

  5. International Maritime Autonomy Remote Navigation Conference at Australian Maritime College Launceston.

    Also on 27 November, Ocius Oceans (our non-defence subsidiary) presented a paper on Bluebottles’ bathymetry trials to an international audience amongst a series of presentations and panel discussions on topics including Autonomous Navigation Systems, Bathymetry & Positioning, Technology and Development.
