Introducing the T-CAP system

After a long wait, Combi Wear Parts latest system for cutter suction dredgers has been successfully tested. Now finally, the patented T-CAP system has entered the market.

– The T-CAP system was tested for the first time in 2019. Back then, the test did not quite live up to the expectations and therefore we had to go back home and improve the design after what we learned from the initial test, says Niclas Wechselberger, CTO at Combi Wear Parts.

This time the new improved version of the T-CAP system was tested during five intense days in Singapore. The test was carried out on a cutter suction dredger of the 7000-kW cutter power class In mixed to hard soil.

Improvements with great results

Important improvements have been made to adjust the shortcomings that the T-CAP system previously showed. Due to the pandemic, Combi Wear Parts had to wait two additional years for the next opportunity to test the system, which took place in September 2022. The result was convincing, and all parties involved were satisfied with the performance of the T-CAP system.

– To meet market demand, T-CAP needed to perform in soft to mixed soils. With that insight, we decided to develop this new system where the tooth protects the adapter by all means, says Niclas.

A traditional system with unique properties

The T-CAP system is designed for soft to mixed soils, but it also proved well suited for dredging in rock up to 40-50 Mpa during the test. The new coupling geometry was coping extremely well with the impact forces that the system must handle when cutting. When inspecting the adapter noses after the test they were still in as good as new condition.

– In all type of dredging projects, it is difficult to understand the complexity and calculate the time required. Then a well-functioning system that does not cause problems is extremely valuable. The T-CAP system proved to be a system that you can rely on. We are now looking forward to selling more of the T-CAP system and to let more users experience the advantages of the T-CAP, says Niclas.
