The software functionalities provided by the
UM are as follows:
• 3 operations state: Maintenance Mode,
Normal Mode, Alarm Mode;
• In Normal Mode the software acquires, logs
and processes every 15 seconds pressure
data to detect events over the normal tide
signal;
• Automatic switch in Alarm Mode in case of
detection of an event and automatic sending
of pressure data via acoustic link;
• Return to Normal Mode after 3 hours

37. EASY TO DEPLOY (ETD) SURFACE BUOY
The Envirtech SB is an easy to deploy “SPAR” buoy
“SPAR”
characterized by a tall and thin configuration. It floats
upright in the water and it has a small water plane and a
large mass. This configuration tends to be a stable ocean
platform. Adjustment of the water plane area and the
mass allows spar buoys to be tuned so they tend to not
respond to wave forcing.
