increased need for strong AF performance 1. Increased idling time in and around ports. 2. Dwell time in some ports exceeds 30 days on average! 1. Increased fouling pressure as world oceanic temperatures is increasing boosting the fouling activity 2. Global trade density moves step by step into warm water zones. 1. Invasive aquatic species are gaining focus and fouling can be factor limiting vessles from entering port. 2. Hull biofouling could be just as serious a problem for the spread of invasive aquatic species (IAS) as ballast water (IMO technical officer Dr. Theofanis Karayannis) Selektope
Hull performance and cost of fuel With medium calcareous fouling, the needed power increase to maintain a fixed speed is around 54%. Also, even if the surface coverage is only 5% (barnacle fouling), the total roughness resistance is only reduced by 1/3 (Shultz 2011). Bio-fouling is the by far most important contributor of increasing resistance and lower fuel efficiency. Source: M Shultz, 2007 Selektope
Novel technology adding dimensions to bio-fouling prevention Bio-repellent mode of action powering coatings for unrivaled static performance Relies on temporary receptor-stimulation of target organism, the Barnacle. Makes hull coatings perform better, saving fuel and reducing emissions. Reduced biocide loadings as efficacy is proven at 100s times lower loadings than conventional alternatives Compliant with regulatory schemes and compatible with existing coating technologies.

Thank you for your attention Although we want to try to control everything (with big data), there needs to be an element of risk taking to create significant change. For further information on these new Selektope-containing coatings improving your operational performance please visit SeaJapan
