Trelleborg’s marine systems operation recently became the first marine fender manufacturer globally to receive extensive anchor design software training from Hilti, after hosting the manufacturer of chemical anchor fasteners at its Engineering and Design Center of Excellence in Ahmedabad, India.
The training saw Hilti experts showcase how Trelleborg engineers can utilize their software to calculate the required resin length for anchors up to M39 in size. Other areas of in-depth analysis included the types of chemicals used in Hilti’s anchor fasteners, their bond strengths and how its fasteners are installed on concrete berthing structures.
Mission critical equipment such as fender systems need to be installed correctly, and anchors play a fundamental role in ensuring that they are, and that they can successfully provide a first line of defence for ports.
With a superior resin strength to its competitors, Hilti’s wide range of injectable mortars are widely regarded as the leading solution used at ports and terminals across the globe. Therefore, it is vital that when designing our anchors, our team ensure they are fully compatible with Hilti’s mortars. The training provided us with everything we need to know to do so.
To accommodate increasing vessel sizes with optimal performance and efficiency, many of Trelleborg’s fenders require anchors larger than M39 in size, beyond the remit of Hilti’s anchor design software. Therefore our engineers have established a proprietary tool to calculate the required resin length for such anchors.
Hilti’s training provided the ideal platform to validate the calculation tool that our team has developed internally, and with the help of their experts establish industry testing requirements for chemical anchors larger than M39, helping to eliminate the use of low quality chemical anchor fasteners across the globe.
Trelleborg’s Hilti training is part of a new initiative for engineers at our Engineering and Design Center of Excellence. The initiative provides practical exposure to those that primarily work in a software-based environment.
