INNOVATIVE LOCK
The Province of Zeeland has tendered the maintenance of the internal low tide doors of the large lock in Vlissingen in 2020.
The aim of this project is to replace the movement systems and additionally the electrical installation for controlling the movement of the doors (execution). The renovation will increase the safety level, reliability, availability and maintainability of the control and movement of the doors.
ABOUT THIS PROJECT
Client: Province of Zeeland
Period: Tendered in 2020 and work will start in the second half of 2020. Commissioned in May 2021 .
Innovation:
A slewing ring with drive pinion, encoder pinion and lubrication pinion. The drive replaces the panama drive wheel. This innovation (first in the world) is robust, compact, has a long lifespan (> 60 years) and is safer.
THE INNOVATIVE LOCK CONTRIBUTES TO THE FOLLOWING SUSTAINABLE GOALS, SUSTAINABLE DEVELOPMENT GOALS (SDG)
SDG 3.9
Safety
The turnable is compact and closed making it safer when carrying out maintenance and inspection work.
SDG 7.2
Renewable energy
The energy required for control and movement is generated with wind energy from the Netherlands.
SDG 8.2
Craftsmanship
Many specialisms from Western Europe with a high added value were used to make the drive.
SDG 9.4
Innovation
This is the first application of a slewing ring drive in a lock. Based on a multi-criteria analysis, it emerged as the best compared to the panama wheel and the hydraulic cylinders.
SDG 11A
Link
The lock has an important access function from the sea to inland waters for fishing, professional inland shipping, pilotage and recreational shipping.
SDG 12.2
Reusable
The drive is robust, has a long service life (> 60 years) and is completely recyclable at the end of its life.
TENDER
In mid-2018, project preparation started with the calculation of the loads on the lock gates and the movement works. After that, a drive principle was determined on the basis of a Multi Criteria Analysis. This led to an innovative principle: a slewing ring drive. This drive is robust, safe, has a long life and is completely recyclable at the end of its life.
After that choice, the design steps followed: preliminary design, detailed design and implementation design. These steps were carried out under the responsibility of the Province of Zeeland. This was followed by a design verification and the tender for the realization. This has been started by contractor Spie since September 2020. After a trial period of 1 year, the following 6 pieces of movement work will be replaced.
For this project we have opted for a unique application. I knew that Dinatec Engineering in Vlissingen worked with slewing rings and this seemed suitable for a lock. After calculations, this innovative application came out on top in the multi-criteria analysis. This technique has potential for other replacement tasks, because many locks in the Netherlands are equipped with a Panama wheel or hydraulic cylinders.
