TRELLEBORG RECEIVES HILTI ANCHOR DESIGN TRAINING

By Richard Hepworth, President of Trelleborg’s marine systems operation

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.

FENDER MAINTENANCE LACKING, LEADING TO DISPROPORTIONATE FAILURE RATES

By Richard Hepworth, President of Trelleborg’s marine systems operation

Our fifth annual Barometer Report, which discusses the issues impacting ports and terminals around the globe, has revealed that over 60% of the port owners, operators, consultants and contractors surveyed have experienced unscheduled downtime due to fender damage. This is a huge increase compared to the last report in 2014, when only 20% cited it as a contributing factor.

At the same time, 25% of those surveyed expect fender systems to have a life expectancy of at least ten years. This is a reasonable expectation, but not when taking in to consideration that respondents are not placing enough importance on regular inspections and maintenance. This is because only 36% carry out maintenance annually, while over 60% of those surveyed said that they, or their clients only carried out inspections and maintenance every two to ten years, far below the recommended frequency of every 12 months.

It’s clear there’s still work to be done to ensure fender maintenance is given the importance it deserves. However, this is only half the story – before maintenance becomes an issue, fenders must be manufactured correctly, using the best design and the right materials and go through stringent testing to make absolutely sure these mission critical components protect port infrastructure over a long and demanding service life, minimizing maintenance requirements.

Fender systems can have very low failure rates and minimal inspection requirements. However, to do so they need to be specified correctly and manufactured using the right materials. For example, the modulus of the rubber compound – the relationship between stress and strain in a cured rubber sample – is one of the determining factor of a fender’s performance, and highly impacted by the dispersion of carbon black filler in the rubber. The level of dispersion, in turn, is dependent on the mixing process, the quality of which is determined by the machinery used in the production of the rubber compound.

After manufacture, fenders must be subjected to rigorous materials and full-scale testing. To ensure they consistently meet working demands and environmental conditions over their lifetime, they need to be maintained correctly. Given the lack of regular inspections and maintenance, it’s unsurprising that 50% of port owners are saying they have had to upgrade their fender systems within the last ten years.

THE IMPORTANCE OF MIXING, MANUFACTURING AND MODULUS

We’re pleased to announce that, last week, we launched a brand new whitepaper and webinar which aim to raise awareness of the importance of ingredient selection, mixing and the manufacturing process in marine fenders.

Building on our previous research into ingredient selection and its impact on fender performance, the new materials highlight that compound modulus – the relationship between stress and strain in a cured rubber sample – is a far more effective and robust measure of fender performance than the traditional ‘hardness’, which is currently used in the industry.

The new research has proven beyond doubt the need for a new measure of fender performance, as ‘hardness’ is unreliable and can be easily falsified. As such, we suggest that the industry moves towards measuring the modulus of rubber compounds, to ensure the characteristics of the fender are truly understood.

Compound modulus is the determining factor of a fender’s performance, and highly impacted by the dispersion of filler in the rubber.  This dispersion, in turn, is dependent on the mixing process, the quality of which is determined by the machinery used.

We have discovered that even a superior rubber formulation – one which uses natural rubber and reinforcing fillers – can be degraded if it is subjected to an inferior mixing process, ultimately producing a low performance compound and a low performance fender.

The uniformity of filler dispersion within the rubber is critical: poor dispersion can lead to damaging effects such as reduced service life, poor performance, poor appearance and even poor product uniformity.

Our new whitepaper discusses the importance of the machinery used to mix the ingredients: there are a number of related parameters that affect filler dispersion in the final mix, including ram pressure, rotor speed and design, coolant temperature and sequence.

The new whitepaper explores which machinery options are most effective and give manufacturers the most control over these critical factors.

The webinar goes into more detail on the importance of measuring modulus, including an examination of filler dispersion in compounds produced by different mixing machines.

We’d love you to read the whitepaper, and watch the webinar – and let us know what you think of the new research in the comments.
