New software predicts fouling control impact on efficiency

Oct 16 2015


AkzoNobel’s marine coatings arm - International - has launched Intertrac Vision, which is claimed to be the shipping industry’s first consultancy tool to predict the impact of fouling control coatings on ship efficiency.

The software, which can be accessed by a trained consultant and delivered worldwide using an iPad or similar, provides an instant assessment of the return on investment (ROI) from the comparison of fouling control coatings prior to application.

 It also allows a consultative approach for hull coating selection, providing in-depth analysis on a vessel-by-vessel basis, the company claimed and was developed as a result of fundamental research into the hydrodynamic effects of coatings in-service, internal research and partnerships with leading academics and marine research institutes.

Intertrac Vision took over four years to develop. The work was led by International’s own scientists who collaborated with the University College London Energy Institute, MARIN, Newcastle University and more than 30 shipowners and operators worldwide.

The software combines an understanding of total hull roughness (micro and macro) and ‘roughness’ associated with biofouling and uses studies carried out by computational fluid dynamics (CFD) on different hull forms in order to make accurate predictions on the impact of fouling control coatings on the comparative powering requirements of a vessel and comprises hundreds of thousands of datasets.

The Intertrac Vision tool, which will be made available as a free consultancy service for shipowners and operators, processes individual vessel parameters, inputted during a consultation and then uses multiple proprietary algorithms and models to provide an accurate and detailed assessment of the impact of each potential fouling control coating choice over the ships specified in-service period.

Key outputs include - ships powering requirement, fuel oil consumption, fuel oil cost, CO2 emission predictions and a full cost benefit analysis when comparing different coatings and surface preparation options.

Michael Hindmarsh, Intertrac Vision’s project leader, said: “When selecting the most effective hull coating technology for a vessel, having an accurate understanding of the return on investment prior to purchasing, is a key part of the decision making process. Hull coatings play a key role in a vessel’s profitability and sustainability, due to the fuel and CO2 savings that can be delivered and shipowners want tangible proof of the benefit prior to application.

“Through Intertrac Vision, we can bring a new level of transparency and choice to the industry, working with customers consultatively to ensure that the most effective and appropriate coatings solution is selected for each vessel within a fleet,”he said.

Tristan Smith, lecturer at the University College London Energy Institute and contributor to the new software, said: “While all technology providers, including those producing hull coatings, have long since offered insight into the fuel and CO2 saving potential of their solutions, shipowners have maintained a degree of scepticism around performance prediction. The lack of accurate and transparent supporting data underpinning statistics quoted has contributed to this mindset. 

“As one of several academic contributors to Intertrac Vision, we aim to support this initiative by bringing the industry a step closer to a new era of robust, rigorous analysis that can help improve the rationality in hull coating selection. This should enable ship owners to explore the ‘what if’s’ and performance prediction uncertainties in such a way that they can then make more informed decisions based on the key variables that influence the performance of fouling control coatings on their vessels,”he said.

The launch of Intertrac Vision follows extensive research and development undertaken by AkzoNobel and the wider shipping industry to enhance understanding of the impact of fouling control coatings on vessel performance. This includes an up-dated study on the development of Average Hull Roughness that was originally pioneered by Dr Robert Townsin of Newcastle University in the 1980’s and is still commonly used today.

Dr Barry Kidd, manager, hydrodynamics, AkzoNobel’s Marine Coatings business, said: “The original Intertrac system was the industry’s first tool to analyse where a vessel had historically traded and uniquely overlaid the fouling challenges that it had been subjected to in those areas.

“While this promoted meaningful dialogue about fouling control coating performance, further research was needed to deliver scientific models that provide instant, definitive and transparent information that predicts comparative performance. Intertrac Vision delivers this, enabling shipowners and operators to make informed decisions regarding fouling control coating selection prior to application with a full in depth economic and environmental analysis.

“Intertrac Vision is state-of-the-art and a tool we will continue to develop to ensure it remains current and relevant to the latest shipping industry market dynamics. In support of this ambition, we would welcome the opportunity to develop new collaborations with interested third parties and ship operators to further develop Intertrac Vision and support future improvements in ship efficiency,”he concluded.
