APPLYING THE RIGHT CORRECTION FACTORS

Richard Hepworth, Managing Director, Trelleborg Marine Systems


Some of my colleagues will be attending the Port and Terminal Technology Conference in Virginia this week. The conference explores the latest developments, issues, trends and technology affecting ports and terminals around the globe, so it’s a great platform to meet with the wider industry and share ideas and best practice.

At the conference, my colleague Mishra Kumar will present a technical paper, “Applying the right correction factors” discussing the importance of applying the right Velocity Correction Factor (VCF) and Temperature Correction Factor (TCF) when specifying marine fenders.

Rubber type and compound formulation undoubtedly have a dramatic impact on the performance and lifecycle of fender systems. It’s essential that specifiers understand the difference that low quality compounds can have on performance – and the impact that rubber type and formulation have on VCF and TCF.

Last year, it’s safe to say we really put our money where our mouth is and delved in depth on the difference between high quality and low cost fenders. Having developed new analytical and chemical tests to determine fender composition, we found some dramatic differences between two fenders which were claimed to be designed to the same specification.

The paper Mishra will be presenting at the conference builds on that work and discusses the impact that these differing formulations have on VCF and TCF – which can’t be applied correctly unless the rubber compound and formulation are properly understood.
