Strainstall's
StressAlert II Hull Stress Monitoring System Technology
is the result of over 30 years at the leading edge of load measurement,
strain and stress determination. This expertice, together with
a strong commercial understanding of vessel operating control
ande safety, means that StressAlert II is more
than just an alarm system.
Advanced information handling and data logging technology monitors
structural integrity indicating deterioration. Combining with
course and speed as well as weather conditions enables operational
efficiency to be improved and vessel safety increased. |

|
|
|
|
|
|
|
|
|
|
|
StressAlert

|
|
|
|
|
|
|
|
|
|
|
|
|
Long
baseline strain gauges, mounted on the deck or in holds
(according to vessel type), measure structural bending.
Bow accelerometer measures the impact of bow slamming.
An optional bow pressure gauge measues dynamic bow draft. |
