MONITORING OF AN OFFSHORE WIND TURBINE TRIPOD DURING PLACEMENT AND ANCHORING IN THE SEA
Subject:

An offshore wind turbine requires a stable and exactly horizontal base. To achieve this, the tripod, on which afterwards the wind turbine will be mounted, must be monitored during the anchoring process.

Measuring task:

The position of the Tripod must be monitored during the anchoring rocess with inclination sensors mounted at the upper end of the Tripod. The sensors must withstand the high accelerations occurring during the ramming process. The measured data must be transmitted wireless to the boat controlling the whole process.

POWER SUPPLY SECTOR / ALIGNMENT OF LARGE PUMP SHAFTS
Subject:

During maintenance works on the pumps of the cooling circuit of a cooling tower in nuclear power plants, quick and precise methods for the required alignment works are indispensable. Large electro motors with vertical axis drive evenly large centrifugal pumps situated one floor below.

Measuring task:

• The horizontal positions of the connecting lines between the bearing faces on the bearing ring for the stator must be checked. The flatness and the horizontal position of the bearing ring must be assured.
• The pump housing, one floor below, must be adjusted horizontally as well.
• The center points of the pump shaft and the drive shaft of the motor must be aligned to each other in order to assure that the transmission shaft can work free of any bending moment.

MONITORING A GENERATOR IN A POWER STATION
Subject:

The operator of a power station wants to ensure that the mechanical strain on the generators remains within the tolerances even during significant changes of power level. 

Measuring task: 

Permanent monitoring of the structure of generator at all critical positions.
