TRELLEBORG DISCUSSES PORT PERFORMANCE AT RUBBERCON 2015

Trelleborg’s marine systems operation was invited to speak at the leading event in the international rubber calendar, RubberCon 2015, in early March, which was held at Hotel ITC Grand Chola in Chennai, India.

Organized by the Indian Rubber Institute (IRI), Rubbercon is the official bi-annual conference from the International Rubber Conference Organization (IRCO). With the theme ‘Shaping the Future through Innovative Technology’, Rubbercon 2015 brought together over 600 attendees to discuss the latest trends and developments in the rubber and allied industries.

At the seminar, Trelleborg technical expert, Mishra Kumar, discussed how 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.

In addition, Mishra also discussed mixing and compound modulus as an effective and robust measure of fender performance.

You can learn more about the topics covered in our recent “Assuring fender Performance” webinar.

TRELLEBORG TO HOST SEMINAR IN PARTNERSHIP WITH PIANC

By Richard Hepworth, President of Trelleborg’s marine operation

With PIANC continuing to set best practice guidance for so many, and varied, issues pertinent to waterborne transport infrastructure, we felt that it was only natural to further strengthen our longstanding association.

As such, we will host an exclusive one-day seminar in partnership with PIANC for port consultants. Held on 30th October at the Atlantic Imbizo Conference and Function Studio in Cape Town, South Africa, the free to attend seminar provides us with the ideal opportunity to develop a better understanding of the needs of consultants, so we can evolve our offering to meet them.

The seminar will see Trelleborg experts discuss a range of key industry issues, including the importance of rubber compound composition in the whole-life performance of fender systems and how consultants can determine the formulation of the fenders they procure. This will see our technical expert, Mishra Kumar, discuss mixing and compound modulus as an effective and robust measure of fender performance. The seminar will also provide valuable insight on rubber and foam marine fender design and selection best practice, as well as the latest docking and mooring innovations to improve efficiency and optimize performance.

TRELLEBORG MARINE SYSTEMS MAKES VISIT TO SRI LANKAN RUBBER FACTORY AND RUBBER PLANTATION

Last month, representatives from both Trelleborg’s marine systems and engineered products operations visited colleagues at Trelleborg’s wheel systems operation, along with a rubber plantation and processing plant in Malwana, Sri Lanka.

The visit to the Wheel Systems operation’s facility provided visitors with the chance to learn about the processes involved in the manufacture of its tires and complete wheels. This also provided the opportunity for representatives of the three business units to share best practice and discuss the commercial and technical challenges facing each of the industries in which they operate.

The visit to the rubber plantation and processing plant provided attendees with the opportunity to broaden their knowledge of natural rubber, the building block of the rubber compounds used in many of Trelleborg’s engineered polymer solutions, including our high performance rubber marine fenders.

Attendees were able to see the extraction of natural rubber, which involves the ‘tapping’ of the Hevea Brasiliensis tree, first-hand. They were also educated on the subsequent processing, grading and quality control of properties within natural rubber.

The trip also saw attendees visit the Rubber Research Institute of Sri Lanka, the oldest rubber research institute in the world, responsible for the research and development of all aspects of rubber cultivation and processing. This provided visitors with an overview of research currently being conducted across the industry, in a bid to increase rubber production yield, improve tapping technique and fight the many kinds of disease rubber trees are susceptible to.

I’ll leave you with some words from our President, Richard Hepworth, about the significance of the trip.

“With a limited understanding of rubber quality and its impact on fender performance across the marine industry, we’ve spent considerable time and resource highlighting its importance.

“With that in mind, the visit was a great opportunity to not only get together with colleagues from Trelleborg Wheel Systems and Trelleborg Engineered Systems Qingdao, but get to grips with the very first step in how natural rubber goes from rainforest to protecting critical marine environments across the globe. A huge thank you to those that attended, our colleagues at Trelleborg Wheel Systems for their hospitality and to Sanjay Melvani and Melissa Asmone for organizing.”

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.

TRELLEBORG LAUNCHES NEW RUBBER COMPOUND FOR TUG FENDERS

Mishra Kumar, Global and Technical Market Support Manager at Trelleborg’s marine systems operation

Tugs may be fitted with up to four types of fender, tadalafil no prescription each serving a particular purpose. The problem is, as tugs have become more powerful, choosing the right type, size and arrangement has become increasingly critical. It’s now more important than ever to look for ways to increase service life, in order to offset the increased damage that comes with the increased power of the tugs.

To accommodate these needs, we’ve recently developed a new High Performance Super Abrasion Resistant (HPSAR) tug fender, which utilizes an innovative, superior rubber compound. The application of this distinctive and improved compound not only significantly increases the service life of the fender, but also gives the fender a lower density than traditional solutions, contributing to reduced weight and increasing potential savings.

With tug vessels used fenders as bumpers to move larger vessels, they are constantly being pushed against steel surfaces that cause the fender to wear and tear quickly. Common complaints about the tug fenders that are currently standard across the market include the fact that they are easily damaged, heavy, and prone to chipping and chunking.

The improved service life and reduced maintenance requirements of the new HPSAR tug fender highlights just how much rubber compound composition impacts fender performance. In especially harsh environments, such as those in which tug fenders operate, this is essential to avoiding incidents and downtime resulting from when standard solutions fail.

The new HPSAR tug fenders have already proved their value in demanding operational environments, and we’ve already secured contracts to supply the HPSAR fender system to two tugs operating in a port in North Western Australia. The port’s previous solution was chipping, chunking and wearing out quickly in a particularly difficult operational environment.

The HPSAR compound provided a much higher abrasion resistance in combination with a set of very high mechanical properties, meeting the client’s need for a longer lifecycle and reducing maintenance costs. As the geometry of the fender was specified by the client to meet the same parameters as the current solution, the improved performance could be isolated to the superior rubber compound.

It is essential that tug fenders using the new compound are specified by more than simply traditional parameters such as abrasion resistance, tensile strength, tear resistance and elongation at break. With that said, to ensure the quality and performance of the new tug fenders, the chemical composition requirements should be specified. This may include standards for density, polymer percentage, carbon black percentage, ash percentage and polymer to filler ratio.

Rubber compound chemical composition should be evaluated upon receipt of the final product, to ensure that the fenders will perform in harsh conditions over a long service life. As such, we’ve developed a new analytical test that allows our customers to do exactly that.

SOUTHAMPTON CONTAINER TERMINAL TURNS TO TRELLEBORG TO ENABLE BERTHING OF LARGER VESSELS

We were recently awarded the contract to supply over 70 Unit Element fender systems to DP World, Southampton, which will berth the latest ultra-large container ships.

I believe that our consistency in performance and engineering expertise has supported our relationship with the terminal.  We’ve worked together for a while now, and this contract brings total amount of fenders supplied to over 110.

Brin Humphreys, head of Engineering at DP World Southampton, said: “Due to the proven performance of the systems supplied by Trelleborg, we had no hesitation in turning to them once again. It was clear they had the capabilities to successfully deliver our expectations and requirements again.”

We have worked closely with DP World Southampton for over 10 years, first installing our Unit Element fenders in 1996 on SCT 1 Berth.

When refurbishment began on SCT berths 2, 3 and 4, in 2011, DP World chose us to keep the solution in line with SCT 1. We are delighted that we yet again had the opportunity to work with DP World Southampton using our unique solutions for such an important project.

On completion of the current project, Southampton will offer 1.87 kilometres of deep water quay, with up to 16 meters depth alongside. In addition, the 16 quayside gantry cranes with super post panamax capacity will allow for berthing of vessels over 400 meters in length.

It is vital that infrastructure keeps up with the ever increasing size of vessels and therefore we are delighted to be designing, manufacturing and installing our bespoke fender systems for a facility that places such importance on proactively keeping up with demand.

 

 

JEBEL ALI PORT RECOGNISES IMPORTANCE OF RUBBER SPECIFICATION

We are proud to announce the introduction of our rubber quality standards at the world’s largest man-made harbor – The Jebel Ali Port in Dubai. We have been working on the Quay Four refurbishment project with DP world since 2011, and have now completed installation with 60 super cone SCN 1300 fenders to project berths 18 and 19.

Super Cone fenders provide optimal performance and efficiency. The unique design makes them an excellent choice in terms of stability, strength and also resistance to over-compression.

The addition of analytical tests to verify the quality of rubber used in the fenders has ensured us to really reassure the port that the high-performance required for this project will be met.

As the biggest port in the Middle East and a supplier to the global market, we are delighted that DP world has shown commitment to superior solutions by building rubber quality standards in to their fender specifications.

Thanks to our entirely in-house approach, we could even personalise the solution for DP World by including the DP World Logo on the UHMW PE face pads of the fenders.

I will leave you with a few words from Hesham Abdulla, Container Terminal 1 director of DP world, who said: “Trelleborg was able to offer technical support across all parts of the system, from ensuring the rubber element would precisely meet specification, to chains and accessories. Their support and local presence meant that they were a natural choice to supply the project and thanks to their in-house manufacturing capabilities we could even have the solution personalised.”

PORTS CRYING OUT FOR EXTERNAL SUPPORT FOR EQUIPMENT SPECIFICATION

Our latest Barometer Report revealed that the majority (77%) of consultants and contractors don’t know the correct ratio of ingredients in a superior rubber compound for use in fenders.

To me, this suggests a huge gap in specification knowledge and product awareness, and that needs to be addressed. As we’ve talked about frequently in this blog, the performance and lifecycle of fenders vary dramatically based on the type of rubber used, and within that, the compound composition of the rubber.

And whilst many lacked awareness of the importance of compound formulation, what’s more, 50% of those surveyed don’t know if suppliers apply bespoke Velocity Factor (VF). 53% are also unaware if suppliers apply bespoke Temperature Factor (TF).

The application of VF and TF on a case by case basis is essential in determining fender performance and lifecycle. First introduced by PIANC, VF and TF should be applied to fenders depending on the compound composition of the rubber to accurately ascertain performance in the field, under varying compression times and temperatures.

Its no surprise then, that the study also revealed 86% of those surveyed would find it useful to have a system that can easily test suppliers’ compounds. The need is there, and it’s time for suppliers to react to it, evolving offerings to provide the required education and substantiation.

I’d like to get your thoughts on the matter. Do you feel that the level of knowledge within the industry is up to scratch when it comes to specification? Let us know in the comments section.

LATEST BAROMETER REPORT LAUNCHED AT PIANC 2014

It goes without saying that the PIANC World Congress represents a landmark event on the maritime calendar. And, with such a wide range of stakeholders from across the industry attending, it provided the ideal platform for us to launch our latest Barometer Reports, which highlight a broad spectrum of issues pertinent to the industry.

To celebrate the launch of the reports, we took the opportunity to host a roundtable at the event that discussed some of the key findings. Against a backdrop of increased and varied demand, one of the main messages from the report was that there is a much more optimistic outlook on investment than in previous years.

In fact, the vast majority of respondents expect both capital and operational expenditure to grow over the next twelve months. With optimism returning, the roundtable delved in to the opportunity for port owners, operators, contractors and consultants alike to begin to navigate towards a more strategic, whole life approach to the design and construction of port infrastructure.

I took to the stage at the AGA luncheon and closing plenary to discuss how port infrastructure is evolving, and how stakeholders across the industry can best keep up and capitalize on the opportunities offered by new trends such as automated technologies. In addition, our technical expert, Mishra Kumar, discussed the importance of applying bespoke Velocity Factor (VF) and Temperature Factor (TF) when specifying marine fenders, and how rubber compound composition impacts these two key factors, as well as performance and longevity.

We also had a comprehensive team of sales and technical experts on stand to take visitors through our latest innovative products and solutions, including our brand new Port Performance Tool. Whether you’re a port owner, operator, engineering consultant or contractor, the new Tool allows you to discover just how well your port’s performance measures up against the industry average.

Trelleborg Marine Systems was Platinum AGA sponsor and exhibitor at the 33rd PIANC World Congress 2014, in San Francisco, California, U.S. The PIANC World Congress 2014 took place on 1 to 5 June 2014 at the San Francisco Marriott Marquis.
