PVE vibratory hammers make Tilburg accessible via water
In Tilburg, a city in the southern part of the Netherlands, a lot of effort is being put to make one of the most important canals ready for the future. The Wilhelminakanaal is widened and deepened over a length of 4 kilometres. A new sluice is also part of this prestigious project. This new sluice has the largest composite lock gates of the world.
The canal, that connects the cities Tilburg and Eindhoven with the river Maas, plays an important role in the accessibility of the province of North Brabant. After finishing the project, the travel time of professional shipping decreases with 30 minutes. Also, the industrial estates of Tilburg are accessible for large inland waterway vessels with limited draft. The new sluice that is being built has the largest composite sluice doors in the world. The doors have an impressive size of 6.2 x 12.5 meters.
Our client Hakkers takes part in this project, that is being coordinated by Heijmans and Boskalis. Hakkers uses the PVE 24VM, PVE 2335VM and PVE 2350VM vibratory hammers to drive piles and sheet piles for the new sluice. These hammers start and stop resonance free, which means that the surroundings do not suffer from harmful vibrations. The hammers are all suspendable from a telescopic mobile crane.
The project will be finished in 2017.
PVE 500M dismantles wind farm Lely in only 180 minutes
The heaviest single PVE vibratory hammer of Dieseko Group successfully dismantled wind farm Lely in the Netherlands. The Nuon Lely offshore wind farm was built in 1992 and had to be dismantled. After 24 years the wind farm was approaching the end of its life cycle and was becoming less profitable.
The dismantling of the wind turbines started in October 2016. The PVE 500M was used to extract the foundation of the wind turbines. Four piles, each 26m long and with a diameter of 3.20 to 3.70m, were removed one by one from the seabed and carried off via pontoons. Because of the enormous centrifugal force of the vibratory hammer, the piles were extracted in only 45 minutes each. The PVE 500M, which is a combination of two 250 kgm carters patented according to our GIANT system, has proven once again to have the power to extract 70 to 80 tons piles without any problems. The PVE 500M is a reliable vibratory hammer which managed to do the job in record time. The project is successfully executed by Hebo Maritiemservice.
During this project the Dieseko Group R&D department carried out several underwater sound tests. The main goal is to gain more insights in sound effects. Results will be shared in a later stage.
Kased Khair, a Dieseko Group client in Egypt, recently purchased a PVE 200M vibratory hammer. The vibratory hammer is currently being used in Port Said, an important port in the north of Egypt. A new embankment is being built here. Because of the strategic location of the city it is very important that the development of the embankment is being executed in the right way and following a tight time schedule. In the port, piles with a diameter of 2003 mm and a length of 2 x 35 meters are being driven. The project is expected to be finalised in 2017.
Mohamed Abdel Moneim, Technical Director of Kased Khair: “One of the service engineers of Dieseko Group was available on site when the vibratory hammer arrived. Various Egyptian dignitaries were present when the PVE 200M first started its activities. The service engineer educated our employees and we benefit from excellent support. We fully trust in the equipment and the people of Dieseko Group and until now they lived up to our expectations.”
