6dae07b0-bf31-4ed3-8f80-f9fd58bd9340Crash Course
Measuring Impacts on Hulls and Humans
May 12-13, 2016

All participants shall learn to:
– install impact recording equipment onboard boats
– extract and save the collected data
– interpret the results of the impact exposure measurements
– understand basic physics of human impact exposure and how injuries occur
– avoid the mistakes most commonly made in data collection
Participants shall experience impacts at sea, to compare the data to the experience

Participants shall become able to conduct trials of their own and understand the results.

Who should attend
Operators and officials responsible for operation of high-speed boats
Persons responsible for acquisitions of boats
Persons responsible for for injuries and health issues
Boat operators and medical professionals
Naval architects and engineers
Boat builders wishing evaluate ride quality of hulls
No prequalification is needed

Participants will install measuring devices on test boats.
Impact and vibration exposure will be measured, both on the hulls and on humans
onboard, while boats are exposed to slamming impacts.
Collected data will be presented and analysed.

The devices to be installed during the course are easy to use. They are the same kind as are in use by the Norwegian and Danish defence forces, UK MoD and the Swedish Coast Guard.

Brief lectures explaining
What exposure causes injuries – and how
What is relevant to know to reduce injuries and ejections
Difference between impacts and vibration
Different kinds of data collection devices available

Science has come a long way in recent years. Still injuries seem to occur more – not less frequently.

Available standards and regulations have no proven correlation to injury risks at sea and are continuously subject to change.

Lab testing can not give sufficient relevant information to assess injury risks.
Neither realistic multidirectional impacts nor human body response can be simulated.
Impact exposure has to be measured at sea – on both hulls and humans.

There is an urgent need for proper and relevant quantification of impact exposure on hulls and humans and proper evaluation of available means to mitigate this exposure.

More agencies are planning to measure impact exposure on personnel on high-speed boats.
By using the same data gathering methods, results from studies done on different boats and in different countries, can easily be compared.


Preliminary Agenda           

Thursday May 12 2016   14.00

Installation of data loggers and accelerometers on demo boats
Boat rides with impact measuring during moderate wake jumping
What causes which injuries?
What is the difference between vibration exposure and impact exposure?
What are the practical requirements to prevent injuries and ejections?
What are the legal requirements and implications?
Which currently used standards are relevant? Why are standards changing?
Discussions and Supper

Friday May 13 2016   08.30 – 13.30
Preview analysis of the recorded impact data
Comparing impacts recorded with impacts perceived – the subjective experiences
Means and methods for long-term monitoring of impact- and vibration exposure
On-board warning system for dangerous impact exposure

Setting up studies
How to set up and conduct your own study for testing hull performance.
How to set up and conduct your own side-by-side, at-sea evaluation of boat seats
How to make questionnaires for scientific evaluation of subjective assessments
Potential cooperation and exchange of results between agencies

Lunch and conclusive remarks
The Royal Institute of Technology in Stockholm will, on request,
offer support by analysing impact and vibration data from such studies.
