Decades of Innovation in Dredging
6 February 2025
In the early 1980s, Straatman introduced an innovation that changed the dredging industry. Our engineers developed the Bow Coupling, a system that quickly became a standard in dredging operations. Since then, the distinctive design and proven reliability of the Straatman Bow Coupling have become well known worldwide. Many dredging vessels still operate with systems based on this original concept. Although the design may look familiar, the technology behind it has continuously evolved over the decades.
Introducing our upgraded bow coupling design
Straatman recently introduced an upgraded bow coupling design. The latest example is a Ø900 male part, delivered to DEME for one of their dredging projects. This new design builds on the proven technology used in the Ø1000 – 30 bar bow couplings. Our engineers have now successfully applied these improvements to the 900 series. The upgrade increases reliability and simplifies maintenance without changing the proven operating principle.
Key benefits of the new design
The improved design offers several important advantages for dredging operators:
- No damage to grease lines caused by chains
- Higher operational reliability
- Longer service life of critical components
- Simpler inspection and easier maintenance
- Lower long-term operational costs
These improvements result from many years of experience in inspection, maintenance, and field service.
Continuous improvement through experience
Straatman has supported dredging contractors worldwide for decades. Through regular inspections and maintenance work, our engineers collect valuable feedback from real operations. This experience drives continuous product improvement. Each new generation of equipment benefits from lessons learned in the field. When you choose Straatman Dredging & Construction, you choose reliable equipment built on decades of practical experience.
A small reminder for operators
And one final tip from our engineers: don’t forget to keep greasing the system. Proper lubrication remains essential for a reliable bow connection and a long service life. Sometimes the simplest maintenance action still makes the biggest difference.
