Innovations made in Germany Antifouling using galvanic currents was tested and reviewed for more than 3 years by the German University Bremen, Department for shipbuilding, ocean engineering and applied biosciences. Experiences have lead to substantial improvements in application and simplifications in installation. TCM Asia will glue down a self adhesive electrode with a width of 20 mm just below the water line and on the deepest part of the keel. Preparation The ship has to have a clean hull. A foundation protecting the submerged hull from osmoses and rust has to be on the hull, TCM Asia use a special 2 component Nano technology based lacquer technology to have optimal protection. Old paint that does not adhere well has to be removed. The following diagrams are partial depictions of the hull to explain installation. The connecting cable is soldered onto the electrode. The glued down electrode (20 mm wide) is covered in the center with a 10 mm masking tape. In 30 mm distance above and below the electrode we apply a wider masking tape The hull surface between the masking tapes is coated at least twice with insulating paint. The soldered current connection is also painted. It is of particular importance to paint the rim of the electrode very carefully to ensure that no water can penetrate underneath the electrode. With the paint the electrode is well connected to the hull which increases long time protection. The connecting cable which is soldered onto the electrodes will be covered several times with insulating paint to avoid galvanic damage to the electrode. After the insulating paint is dry the masking tape in the center of the electrode is removed to uncover the electrode. The masking take below and above the electrode remains. Now we apply a special current conducting paint at least twice on the entire surface between the 2 remaining masking tapes. This special paint protects the electrode from moisture and galvanic damage and increases conductivity for the low voltage current. When the conducting tape is dry we remove the masking tape. The electrodes at the water line on the keel are now ready to use To protect the connecting cable of the electrodes from damage, it is necessary to laminate it in protective tubing and to glue it down carefully. The cable is hooked up to the electronic control device. A separate battery of 50-200 AH (depending of the size of the ship) is connected to the control device. A solar panel of 30 to 60 W (depending on the size of the battery) is required to supply energy to the battery. We will offer soon optionally a fuel cell technology for power supply.
