PIANC SEMINAR A SUCCESS!

By Richard Hepworth, President of Trelleborg’s marine operation

At the end of October, we hosted a joint consultants’ seminar in South Africa with industry body PIANC. I’m pleased to report that the event was very well attended, with around 75 consultants, port authority representatives and construction company stakeholders joining us for the day.

At the event, representatives from Trelleborg discussed rubber specification, our new ReadyMoor Quick Release Hook and environmental monitoring systems, and hosted sessions on foam products and the importance of fender testing.

PIANC continues to do extremely important work, setting best practice guidance for our industry concerning the many and varied issues pertinent to waterborne transport infrastructure. As well as giving us the opportunity to strengthen our relationship with PIANC, the seminar also gave us a great opportunity to develop a better understanding of changing requirements within the market, so we can ensure we continue to work to evolve our offering to meet them.

A huge thank you to Amit Madan, our IMEA Regional Director for organizing the day.  I look forward to the next one!

 

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 TO SHOWCASE NAVIGATION BUOYS AT SEAWORK 2015 INTERNATIONAL

Ashley Tasker, Global Business Development Manager for Marine Products at Trelleborg Marine Systems

I am delighted to reveal that we will showcase our innovative range of IALA compliant modular navigation buoys at Seawork 2015 International, the largest and fastest growing international commercial marine and workboat exhibition and conference held in a European working port environment (16th to 18th June).

Our unique, comprehensive range of navigation buoys provides a solution to fit all demanding requirements – in addition to our standard range, we are able to manufacture to specification where required. The modular system provides an easily transported option to cut down turnaround time and enable fast installation, as they can be shipped in sections and assembled on site.

Manufactured from impact resistant, colour-fast, UV stable materials and comprising of sectional hull pieces filled with marine grade, water-resistant foam, Trelleborg’s range of IALA compliant modular navigation buoys is built around a hot dipped galvanised steel core. Available as standard in diameters ranging from 1.25 to 3.6 meters, Trelleborg will also manufacture precisely to specification where required.

We will also be taking the opportunity to showcase our range of Foam / Elastomer constructed mooring buoys. Thanks to their low maintenance, self-fendering resilient foam bodies and their ease of handling and repair whilst offshore, these are rapidly replacing traditional steel mooring buoys.

Our booth will also feature our pneumatic and foam fenders. As an ideal ship protection medium for load sensitive structures such as LNG vessels and ocean platforms, our range of pneumatic fenders feature high energy absorption with low reaction force. While our foam fenders are super tough due to a unique manufacturing process and have high energy absorption for their reactive load.

If you’re heading to Seawork 2015 and want to find out more, come and see us at booth number A187.

UNSCHEDULED DOWNTIME IS STILL HOLDING BACK THE PORT INDUSTRY

Our latest Barometer Report has revealed that unscheduled downtime is still a problem in the port industry.

We found that 74% of port owners and operators are still suffering unscheduled downtime. Fender damage was the most frequently cited cause, with 20% of owners and operators having suffered downtime due to damage to their systems.

The high incidence of fender damage and the subsequent downtime may be due to a lack of awareness on how to specify a truly quality system, something which really needs to be improved upon. 61% of the consultants and contractors we surveyed claim that their clients are concerned about upfront purchase costs, which could explain the poorly-performing solutions.

To me, the results of the survey suggest that fender system performance and quality is a serious issue. Two-thirds of port owners and operators say that they have upgraded their fender systems in the last five years – despite the fact that fender systems have an intended design life of 25 years.

The many upgrades which have taken place in recent years could be indicative of poor quality solutions which have to be constantly upgraded, with clients’ focus on cost-cutting a potential cause.

Levels of unscheduled downtime have decreased over time, which is a positive step, but any amount of downtime is costly in terms of lost revenue and damaged reputation. Concern about upfront costs is understandable, but in the long term, poor solutions can result in even bigger costs. Contractors and consultants should educate themselves on how to specify quality to steer clients away from cost-cutting upfront and towards investing in quality solutions that will perform well over a long design life.

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 CLAIM PIANC CERTIFICATION KEY TO COMPLIANCE AND REGULATION

The results of our latest Barometer Report show that the majority (65%) of port owners, operators and contractors request and check PIANC certification to ensure that marine fenders are sold as described.

Although it’s reassuring to see that the majority of respondents do request certification, it’s important that owners and operators understand exactly what to look for. PIANC is undoubtedly an important standard bearer for quality and performance, but it doesn’t have the legal mandate to enforce standards across the industry.

At present, it’s too easy to gain PIANC certification, with some of the more unscrupulous traders using this to their advantage by applying certification to entire product lines or factories, rather than to specific product batches and compound formulations.

In comparison to last year’s report, which revealed that just under 80% of respondents were struggling to get to grips with unscheduled downtime, this year’s Barometer reveals that, alarmingly, over 90% are now suffering, which suggests to me that the emphasis placed on checking certification in theory, is not necessarily translating to best practice.

It’s therefore imperative that equipment specifiers, for mission critical equipment such as fenders, begin to take necessary steps to ensure that the products they are buying are truly “as described”.

I’d like to get your thoughts on the matter. How much importance do you put by third party certification and design approvals when procuring mission critical equipment? Let us know in the comments section.

RUBBER QUALITY: UNDERSTANDING THE IMPACT

The issue of rubber quality in fender systems is one that the market cannot continue to be complacent about.

A best writing paper typical fender system is constructed from both steel and rubber, and whilst the steel component will, rightly, undergo extensive testing to meet stringent standards, the importance of the fender’s rubber element is often overlooked.

In recent years, there has been a significant evolution in rubber manufacturing industries: we’ve seen the emergence of contract mixers, locations such as China and India becoming mainstream hubs, and the availability of a wider range of ingredients for rubber compounding.

These changes represent a break from tradition, and best practice in rubber compounding needs to keep pace.  The market must take the necessary steps to educate itself on this evolution and understand the effects these changes have on the performance and lifecycle of fenders.

We’ve recently launched a new whitepaper which delves into the issues of Velocity Factor (VF) and Temperature Factor (TF).  First introduced in PIANC’s “Guidelines for the design of fender systems, 2002” they should be applied to rubber fenders at the testing stage, to accurately ascertain performance in the field under varying compression times and temperatures.

Changing rubber compound ingredients have a direct effect on the characteristics of the fender and as such, VF and TF are greatly affected by the type of rubber used, be it natural or synthetic – and within that, virgin or recycled – and further still by the compound composition of the rubber.

VF and TF must be calculated and reported on a case by case basis.  Each is dependent on the make-up of the rubber compound, and as such, there is no “standard” factor that can be applied to calculate and report performance under varying velocities and temperatures. The degree of VF and TF applied will change depending on the rubber compound and, subsequently, from manufacturer to manufacturer.

PIANC’s recommendations for applying VF and TF are really only the beginning.  Suppliers need to make the appropriate investments in R&D to be able to underpin and substantiate their claims. Anecdotally, we’ve found that many actually copy factors which are not relevant to their products.

If suppliers aren’t able or willing to take the necessary steps to understand and be able to guarantee the quality of their products, then it’s essential that specifiers can to avoid throwing good money after bad on systems that are not fit for purpose.
