Optoelectric dock deflectometer is intended for identifying the vertical bend value of floating drydocks during their operation. The control of the bend value is executed for three points. One of them is the base unit positioned in the center of the top deck of the right tower, and the other two are registration marks at the fore and aft of the right tower correspondingly. The deflectometer has successfully passed the voluntary certification of the Russian Maritime Register of Shipping.
CHARACTERISTICS
Deflection measurement range: ±200 mm
Registration mark positioning range (lengthway, distance): 20...100 m
Size of the registration mark: 109×45×79 mm
Root-mean-square deviation of random component of measuring error at up to 100 m: 4 mm

ADVANTAGES OF THE DEVELOPMENT
Can be connected to a floating dock’s diving controls
High-precision control (shift range of up to 200 mm at the margin of less than 4 mm at distances from 20 to 100 m) in severe weather conditions
Full automation of measurements and their indication
