CONTENTS
With thanks to
ANTIGUA & BARBUDA• Antigua & Barbuda has 0.1% of the world population but 2% of the world’s fleet
making it ranked in top 25 world’s merchant fleets
• Antigua & Barbuda celebrates over 30 year membership of the IMO
• Antigua & Barbuda building on previous British maritime heritage over 35 years
• So, natural links between Antigua & Barbuda & British ultrasonic manufacturer
• This is an example of international cooperation but has wider implications
thanks to our presence at the IMO today
HISTORY OF
ULTRASOUND
• Ultrasound utilised throughout Nature for
communication, navigation, exploration and detection
• Airborne Ultrasound – Bats
• Waterborne Ultrasound – Whales & Dolphins
• 101 Years of utilisation by Humanity
101 Years of British Ultrasonic History
CONTINUED EVOLUTION
& IMPROVEMENT
• Deployed by Royal Navy for SONAR & ASDIC
• Expanded into Thickness, Level, Watertight, Flow,
Cleaning, Condition technologies
• Coltraco is a living example of Evolution – 8
Generations of Level indication technology alone
History of Ultrasound II

FIRE
SAFETY
• Nobody doubts how critical Fire Safety is for Marine environments
• At Sea, each Vessel & her crew are their own Fire Service
• Anecdotes and experiences abound of the potential dangers &
implications of fire at sea
• Current trending issue gaining awareness and recognition
• E.g. incidences of tankers and ro-ro vessel types in the press
REGULATORY
COMPLIANCE
& LACK
THEREOF• Numerous regulations surrounding maintenance of
fixed & portable fire systems
• Marine Servicing Companies providing annual
servicing & certification
• Bare minimum considered sufficient
• But shortcuts sometimes taken
• E.g. Valves left shut; only a sample of cylinders
inspected due to time pressure for Servicing
• Despite current framework, sometimes the
standards are not being upheld
Fire Safety II
MAINTAIN
FIXED FIRE
SYSTEMS
Fire Safety III• CO2 system is a primary weapon for every vessel in fighting
major fires, especially in engine rooms
• IMO SOLAS FSS mandates crew test; sometimes ignored
• Key methods for checking cylinder content:
weighing or liquid level
• Safeship Solution: handheld ultrasonic liquid level indicator and
convert level to agent weight. Example: 30 secs to test one
cylinder with 1 person*
How to inspect Cylinder Content?
*30 secs for the Portalevel® range from Coltraco Ultrasonics
1. Place the Ultrasonic Sensor on
the side of the cylinder, above the
liquid level.
2. Engage the CAL
function to
correctly set up
the unit for each
individual cylinder.
3. The main unit will
display a different
reading for gas
phase and liquid
phase – allowing
user to identify
liquid level accurate
up to 1.5mm.
4. Results: Linear & Bar Graph reading
shown on display for ease of use.
HOW ULTRASONIC LIQUID
LEVEL INDICATORS WORK*

• Land based Industries e.g. Data Centres, Power Stations are
continuously monitoring fire systems
• Annual Inspection and lack of onboard maintenance program
leaves vessel vulnerable for 364 days a year
• Example: 15 mins to weigh one cylinder with 2 personnel = 16 in 4
hour period
• Technology exists to monitor fire systems constantly
• Potential future within Shipping to check CO2 and clean agents
Fire Safety IV
POTENTIAL FUTURE FOR
CONSTANT MONITORING
VESSEL
STABILITY
• Vessels operating in the harshest of environments
• Incredibly intense utilisation places great strain on
structure of the vessel over its lifetime
• This can have huge impacts upon numerous areas –
many well documented, others less so
IMPORTANCE
OF ROOM
INTEGRITY• Fire systems require room integrity to be effective
• ISO 14520 testing Watertight & Space Integrity is critical
• Upon discharge, if the agent is not contained within the
space, the fire may not be extinguished
• Yet, post construction, despite such issues as new cabling
being run and vessel stresses, new integrity tests are rare
• Land based facilities take great attention monitoring Room
Integrity condition – shipping can now too
Vessel Stability II
LEAK DETECTION SOLUTIONS & 24/7 MONITORING• Ultrasonic Technologies are clean, quick & highly accurate methods
• Familiar to Marine Industry – commonly used by Marine Surveyors,
P&I Clubs & Bulk Carrier fleets for Watertight Seal inspections
• Possible to monitor in fixed or semi-fixed nature to ensure
neglected area is alarmed, whilst not adding to crew workload
Vessel Stability III
1. Magnets attach the generator to
the hatch combing2. Use the receiver
wand to take an
open hatch value
3. Close the hatch-
covers and begin
testing the seals.
Accurate to 0.06mm.
4. Results: Linear & Bar Graph reading
shown on display for ease of use.

THE FUTURE• Ultrasound’s potential is currently under-valued in shipping
• Ultrasound technology has a huge amount to offer today
• Ultrasound has potential to dramatically enhance:
• Watertight Integrity
• Flood Detection
• Fire Fighting System Operability
• Room Integrity Monitoring
• Scientific understanding is critical for future Safeship solutions
Vessel Stability IV
A FUTURE LED BY
SCIENCE• Integrity
• Ultrasonic expertise rooted in Royal Navy Sonar – Submariner
• Evolving expertise from innovation to products & systems
• Long term scientific approach & working with Universities
• Excellence in Research & Development
• Involvement with All Party Parliamentary Maritime & Ports
Group and working on the ISO Standards for Gaseous Systems
