Consmema to construct new tow vehicle for maritime research center Ostend.

7 October 2022

Consmema in Hattemerbroek will build a tow vehicle for the maritime research center in Ostend. The Flemish government, together with KULeuven and UGent, are conducting research on the influence of waves, tides and wind on vessels and objects in the sea. The tow vehicle is unique in the world and will be delivered turn-key by the end of 2022.

The research facility in Ostend includes a large towing tank and a coastal and ocean basin. The towing tank is the only one in the world in which fully automatic maneuvering tests can be carried out in shallow water with ship models up to 8 meters long. In the maximum water depth of 1 meter, waves can be generated with an amplitude of up to 20 centimeters. The tow vehicle that Consmema will build resembles a fully automated train set. The structure weighs nearly 100 tons, is 23 meters wide, nearly 4 meters high and can tow ship models through the water at high speed.

Because of the low water level and the required scale of the tests, this vehicle must be very stiff and the axles must be built with extreme precision. To allow the scale models in the towing tank to move in all directions, the tow vehicle is equipped with axles for lateral movement, elevation and rotation. “It is like building a mega-large milling machine with a stroke of 174 meters in the X direction and 20 meters in the Y direction,” says Consmema director Johan Kooij.

Towing tank unique in the world

The towing tank for which Consmema’s tow vehicle is being built is 174 meters long and 20 meters wide. This is a lot larger than the current towing tank at the Flemish government’s Hydraulic Laboratory in Antwerp. This was built in 1991 for testing ships up to 300 meters long and with a capacity for 5,000 containers. Many current ships are over 400 meters and have a capacity for 25,000 containers. Consmema will assemble the complete tow vehicle in its premises in Hattemerbroek, after which it will be partially disassembled and transported to Ostend.

About Consmema
Consmema are suppliers of high quality steel, aluminum and stainless steel products. We have experience with large-scale research projects world-wide. The company is part of The Machinery Group and is located in Hattemerbroek, Netherlands. Consmema and partners will deliver this multi-million dollar project turn-key at the end of 2022.

About the maritime research center
The maritime research center is located on the grounds of Plassendale 1, in the inner port of Ostend, and is part of the Hydraulic Laboratory, a division of the Department of Mobility and Public Works. For more than 80 years, this laboratory has been a centre of expertise for research and consulting on hydraulic, nautical, hydraulic, sediment-related and hydrological issues. The Flemish government, together with UGent and KULeuven, conduct essential research for shipping and the accessibility of the Flemish seaports.

Proud to support the CeleRacingTeam!

5 April 2022

This year the CeleRacingTeam consisting of 16 students and 2 accompanying lecturers of the Gymnasium Celeanum in Zwolle, will participate in the Shell Eco prototype race. They will compete in the prototype class this year. This class is all about designing the most energy-efficient vehicle; Comfort is less important. They are building the vehicle in collaboration with students from Windesheim College. Windesheim students will be involved in the design of the the battery.

Breakwater blocks for the IJsselmeer Dam (Afsluitdijk) in production 

10 March 2022

The first concrete breakwater block for the Afsluitdijk! Last week, construction consortium Levvel proudly presented the concrete breakwater element. Consmema developed the concrete moulds for the consortium. 

Concrete moulds 

We may say that this projects runs smoothly. In fact, the concrete moulds move through the plant on carts. During that process, the blocks have the time to harden properly. They are then stacked by a crane for their final hardening period. Eventually, a pontoon ships these Levvel Blocs to the Afsluitdijk. 

Protecting the Afsluitdijk 

We are dealing with rising sea levels. To protect the Afsluitdijk for the next 100 years, the innovative concrete wave breaker elements were designed. In the coming years, Levvel will install 75,000 of these breakwaters on the dike.
