This presentation covers the topic of unmanned marine vehicles and how they can be used to improve the search capability of rescue vessels.
It was originally submitted to the International Maritime Rescue Federation as part of the Future Technology Panel.

INTRODUCTION
• The application of 'Unmanned Marine Vehicles to Maritime
Search & Rescue' was presented at the 2nd FTP meeting in
Gothenburg, Sweden, November 22, 2016
• It was reported in the ‘Maritime Executive’:
http://www.maritime-executive.com/editorials/unmanned-
vehicles-could-aid-search-and-rescue
• This presentation will look at a specific role – Augmenting the
Search capability of Rescue Vessels.

TIME IS THE ENEMY OF US ALL
This is particularly the case for someone in distress in
cold waters.

SCENARIO (1)
• Work with a 15 – 20m SAR Lifeboat
• Search for missing person(s) (hopefully with flotation and
thermal protection to give reasonable survival time).
• The Unmanned Marine Vehicle (UMV) would be employed
to increase the breadth of the Search Track – thereby
reducing search time for a given area.
• UMV could also search in areas of navigational hazards
which may not safely accessible by the SAR Lifeboat – near
shore, surf, etc.

Scenario (2)
• Search may have restricted visibility conditions. – UMV can
assist by:
• Use of First Person View (FPV) – viewing directly from the
UMV.
• Use of Night Vision (IR) cameras
• May use aerial device (drone / tethered drone / kite /
balloon / other?) to increase breadth of search.
• Aerial device may have significant wind-speed / flight
duration limitations.

Augmenting the search by a SAR Lifeboat
• Figure 2 shows a UMV increasing the breadth of the search
track by a SAR Lifeboat.
• Figure 3 shows the breadth of the search track being
dramatically increased by the addition of an aerial search
device.
• The breadth of the search track is subject to a variety of
limiting factors, but could generally be further increased by
additional UMV / aerial units.

Examples of various Unmanned Marine Vehicles
which may be applicable to the ‘SEARCH’ function
• Figure 4 – a concept of a very small craft which could be
launched from the SAR Lifeboat
• Figures 5 & 6 – Personal Watercraft sized vessels which are,
or could be, equipped for remote control
• Figures 7 – Somewhat larger UMV which could have
additional SAR capabilities
• Figure 8 – Existing vessels can be converted for unmanned
operation.

Examples of Aerial Systems
• Figure 9 – Waterproof Drone (IP67 rating; test - immerse in
water up to 1M).
• Figure 10 – Tethered drone; extended flight duration.
• Figure 11 – Kite system on USN experimental unmanned Sub
Chaser.
• Note that each of the available aerial systems may be
subject to various operational restrictions, wind speed &
direction, flight duration.
• Aerial systems may also improve communication range.

COMMUNICATION SYSTEMS
• Figure 12 – Advanced broadband communication system
• Various communication & control systems are available,
ranging from limited short range up to satellite based
systems.
• Reliability, range and cost affect the choice.
