VHT proposed the solution to the stick-slip-problem in the form of a sealing system tailored to the application.
Right from the start of the commissioning of the Oosterscheldekering (Estern Scheldt storm surge barrier) the stick-slip effect was noticed associated with the hydraulic cylinders which open and close the sluice gates.
Project-based approach
Thanks to the experience and knowledge of VHT, it was not very difficult to determine the cause of the problem and to select a possible solution. VHT proposed the solution to the stick-slip-problem in the form of a sealing system tailored to the application.
Replacement proces
The sealing was then constructed for three cylinders. The assembly of the new sealing is a very delicate job. After completing the project a bigger test phase was started by fitting another 20 cylinders (for ten sluice gates) with new sealing and then to monitor them for the period of a year.
External party
The job has then been put to tender at an external party in accordance with European procurement regulations. VHT supplied all support possible to train the employees of the company and to inform them on the correct assembly of the sealing.
