New Hempel coating promises fouling-free operations for 60 months

Hempel has launched a new antifouling coating, Atlantic+, designed to protect the hull from fouling for service intervals up to 60 months. Atlantic+ incorporates a powerful biocide package and proven binder system. This ensures progressive and controlled self-polishing immediately following application. The coating is also reinforced with Hempel’s patented microfibre technology, Hempadur Ultra Strength Fibre....

Number of ships using Selektope containing antifouling expected to double

The number of ships using a Selektope-containing antifouling coating is expected to more than double in 2019 following a successful 2018. Selektope, a barnacle-repelling antifouling ingredient has been developed by Swedish company I-Tech. The organic, non-metal compound temporarily stimulates barnacle larvae’s receptors, preventing them from attaching to any ship’s surface. The effect lasts only a...

HullWiper partners with Immersub to tackle biofouling

HullWiper has signed an agreement with Indian Ocean-based underwater hull cleaning specialists Immersub, marking its first step into the African continent. HullWiper’s Remotely Operated Vehicle (ROV) uses adjustable seawater jets under variable pressure to remove fouling. No brushes or divers are required, minimising the risk of damage to hull coatings and to human life. Removed...

Biofouling initiative launched

An initiative to target the transfer of aquatic species via ships’ hulls has been launched. The GloFouling Partnerships project, which is a collaboration between the Global Environment Facility (GEF), the United Nations Development Programme (UNDP), and the International Maritime Organization (IMO), will drive actions to control and manage ships’ biofouling under the IMO Guidelines. The...

I-Tech develops dissolvable packaging for antifouling ingredient

Swedish company I-Tech has developed a new drop-in, dust-free dissolvable packaging system to improve the way antifouling ingredient, Selektope, is added to marine coatings during manufacturing. Selektope is an organic, non-metal molecule that works by stimulating the receptors of any barnacle larvae as they come in to contact with it on the surface of a...

The molecule targeting shipping’s biofouling problem

A recently developed bio-repelling antifouling ingredient known as medetomidine, already used as a sedative in drugs for humans and animals, is finding a new application in the marine coatings industry as a biological deterrent preventing barnacles from settling on ships’ hulls and other surfaces. Swedish company I-Tech is responsible for the introduction of this bio-technology...

Selektope chosen to target biofouling problem at South Korean yards

Antifouling ingredient Selektope, is facing increasing demand from South Korean shipyards as a result of severe biofouling problems on idle newbuilds due to rising global temperatures. Fouling on newbuild ships is a major issue as it affects the vessel’s performance and energy efficiency during sea trials. Many South Korean shipyards are experiencing exacerbated fouling rates...

AkzoNobel develops UV-LED based antifouling technology

AkzoNobel has confirmed it is to develop an antifouling technology alongside health technology company, Royal Philips, which will use ultraviolet light-emitting diodes (UV-LED) The solution will be applied to underwater surfaces, such as ships’ hulls, to prevent biofouling.  If untreated, biofouling can increase resistance of the ship through water and heighten fuel consumption. The innovative...
