Our underwater coating systems offer a TBT-free, copper-free and biocide-free solution for the protection of your vessel. Our protection and performance systems are the Best Available Technology for reduction of fuel consumption, GHG and other emissions through improved hull hydrodynamics and fouling control.
Stringent independent tests were carried out in the Netherlands to provide scientific data and to authenticate the non-toxicity of our coatings. Similar testing was conducted in Canada with the same results. This research proved that the coatings are 100% non-toxic and that there is no negative effect on the water quality or the marine environment at any point of their use. The massive amounts of VOC and zinc anode emission associated with conventional coating systems are reduced to almost zero.
Getting rid of repeated environmental hazards
All our systems require only two coats of 500 µm each applied to bare steel, aluminum or glass-reinforced plastic (GRP). No primer, no midcoat, no tiecoat, no topcoat are needed; just two layers forming a homogeneous protective coating. They are applied once in the life of the vessel which is a major advantage compared with other coatings. If you reapply three to four layers of antifouling coating and are re-doing the above every three to five years, you inevitably come to a point where there are too many layers on the ship’s hull. This will degrade the quality of the coating even more easily and rapidly because of the internal stresses being built up, resulting in a required full reblast. A big environmental hazard is created each time. Repeat applications mean repeated VOCs and repeated debris when the conventional coatings are removed.
Easy and environmentally friendly fouling removal: solving the NIS problem
Over the last several years there have been concerns that non-indigenous species (NIS) are transported by fouled hulls even more than in ballast water. Once a hull becomes heavily fouled there is an increased risk of transporting NIS. This needs to be remedied either by out-of-water removal or by underwater cleaning. In this respect, underwater cleaning has come under some scrutiny out of fear that viable NIS are released and spread by the operation, rather than contained and disposed of. Several ports and countries have banned underwater cleaning out of concerns of pulse release of biocides and an increased risk of transferring NIS.
Another important outcome of the independent test was the submission of the results to port authorities and environmental agencies worldwide in order to allow the underwater treatment of our coating systems. As a result several economically important ports have made an exception to the ban and this only for our coatings. These ports recognize the negative impact of biocidal paints and want to support environmentally safe solutions.
Underwater hull maintenance is carried out with specially designed underwater hull cleaning tools that simultaneously clean and optimize the smoothness of our coatings. This can be repeated whenever needed during the vessel’s lifespan without causing damage to the coating’s surface. It even significantly improves their hydrodynamic characteristics, keeping the surface hydrodynamically smooth and bringing about a major saving in fuel.
Fuel savings reduce ecological impact tremendously
The emission of greenhouse gases (GHG) such as carbon dioxide (CO2) and nitrous oxides (NOx) as well as pollutants such as sulfur oxides (SOx) and particulate matter (PM) into the earth’s atmosphere by the burning of fossil fuels to drive ships is of increasing concern internationally.
Underwater ship hulls are subject to biofouling, as micro-organisms and vegetable and animal matter naturally attach to a ship’s hull. A fouled hull carries with it a fuel penalty. The worse the fouling, the slower the ship will sail at a given RPM. More power will be required to keep the ship sailing at a given speed. This means higher fuel consumption. Depending on the degree of fouling, this can be as much as 85% more. Higher fuel consumption results in more greenhouse gases and other emissions which pollute the earth’s atmosphere.
On a global scale the potential for the reduction in fuel consumption and greenhouse gas emissions is enormous. The annual fuel consumption by the world fleet is estimated at 350 million tonnes. This implies an annual CO2 output of approximately 850 million - 1.1 billion tonnes. If 80% of the world fleet would switch from biocidal antifoulings to our coating systems, this would save an estimated 28.5 million tonnes in annual fuel consumption and 90 million tonnes in annual CO2 output.
We offer a TBT-free, copper-free and biocide-free solution. No toxic substances are released at any stage of its use. The surface texture improves with repeated underwater hull maintenance. Fuel consumption as well as GHG, VOC and zinc anode emission is thereby reduced. This makes our coating systems the Best Available Technology (BAT) for companies that takes their environmental responsibility seriously.
