AUVs - Three Stages of Development

• 1st Generation Ending in the mid 1980s
• AUV technology development
• Significant government involvement
• Many vehicles did not get off their tether
• Canada, France, United States
• ISE partnered with Bedford Institute of
  Oceanography (BIO)
• 2nd Generation Ending in the mid to late 90s
• AUV Applications development
• Significant government involvement
• Many successful demonstrations
• Canada, France, Germany, Great Britain, Italy,
  Japan, Norway United States, USSR
• ISE partnered with BIO, Department of National
  Defence
• 3rd Generation - Commercial Development
• for ISE, commencing around 1999

5
1998-9 at ISE Entering the 3rd Generation

• Government goals realized
• Several successful AUVs ranging from 60 to 9400
  kg but no developed product
• Not sure where the customers were

6
At this point

• Offshore Market - (O and G)
• Cluttered with AUV entrants
• The deep survey market would only support 4-5
  AUVs for the medium term (2000 2010)
• Offshore Market - (Cable Route Survey)
• No demand
• Military Market
• Priorities and requirements undetermined
• No significant opportunities other than in
  Defence Labs (nationalistic)
• Science sector more or less vacant

This led to our decision in 2000-2001 to consider
an AUV design aimed at meeting requirements in
the Marine Science Oceanographic sector
7
We were also guided by one other example
Developed initially for the science sector and
now being marketed to other users in other
undersea applications

Why Develop a Vehicle for Science?

• Need for AUVs in science is real and increasing
• General scientific requirements are well known
• Procurement process is straightforward
• Users are linked by networks in which they share
  equipment (and experiences)
• User is moving away from AUV development -
  opening up a substantial future market

• Modest budgets
• Few - if any multiple vehicle orders
• individual requirements and configurations will
  vary
• Long term usage demands ability to adapt to new
  configurations and built-in growth capability

Working in this environment requires a modular
design that can be adapted by the user to
accommodate varying payload configurations and
future growth
