Ocean Infinity & partner
Proving a comprehensive seabed exploration system for water depth down
to 6000 meter consisting of 6 (8) AUV’s and 6 (8) USV’s from one host
vessel.
Ocean Infinity partnered with Swire Seabed who own and operate the
vessel, do all project management, survey support, processing and
reporting.

Evolution of efficient seabed mapping
So why multiple?
The seabed survey started with led line,
Continued with single beam echosounders
Then Multi beam echosounders
Towed sensors, ROV, AUV
And then the next must be a fleet of AUV’s.... Up towards 900 line km a day..
Survey ROV

HARDWARE SOLUTIONS
• Reliability, performance and
instant access to huge data sets.
• The storage on-board the ship
can handle 120TB of generated
monthly survey data, or over 600
average sized PC hard drives
being filled up each month.
• Scalable network architecture
• The 160Gbps backbone across
the platform is equivalent to
simultaneously transferring 100
high-definition movies every 30
seconds.
• Deployed in building blocks,
and joined together with
virtualization to form a larger
compute cloud.
• Each node is packed with the
capability to run complex
algorithms and image
processing whilst independent
enough to tolerate hardware
failures.

• One virtual macine workplace is for the
Eiva WFM user interface
This in turn remote control one or more
additional virtual machines.
• One data processor on shift dedicated to
navigation and MBE basic processing only.
• Record so far is processing of 3 auv dives in
less than one 12h shift.
Total of 125h of data.
