  "text": "Technique\nDescription\nApplicability\nWaste and waste water management\n(a)\nSegregation of waste and waste water streams\nDocks and slipways are constructed with:\na system to collect and handle dry waste effectively and keep it separate from wet waste;\na system to separate waste water from storm water and run-off water.\nOnly applicable to new plants or major plant upgrades.\nTechniques relating to preparation and coating processes\n(b)\nRestrictions for adverse weather conditions\nWhere the treatment areas are not fully enclosed, blasting and/or airless spray coating are not carried out if adverse weather conditions are observed or forecast.\nGenerally applicable.\n(c)\nPartial enclosure of treatment areas\nFine nets and/or water spray curtains are used around areas where blasting and/or airless spray coating are carried out to prevent dust emissions. They may be permanent or temporary.\nApplicability may be restricted by the shape and size of the area to be enclosed. Water spray curtains may not be applicable in cold climatic conditions.\n(d)\nFull enclosure of treatment areas\nBlasting and/or airless spray coating are carried out in halls, closed workshops, areas tented with textiles or areas fully enclosed with nets to prevent dust emissions. Air from the treatment areas is extracted and may be sent to off-gas treatment; see also BAT 14 (b).\nApplicability may be restricted by the shape and size of the area to be enclosed.\n(e)\nDry blasting in a closed system\nDry blasting using steel grit or shot is carried out in closed blasting systems equipped with a suction head and centrifugal blasting wheels.\nGenerally applicable.\n(f)\nWet blasting\nBlasting is carried out with water containing a fine abrasive material, such as a fine cinder (e.g. copper slag cinder) or silica.\nMay not be applicable in cold climatic conditions and/or in enclosed areas (cargo tanks, double bottom tanks) due to the heavy mist formation.\n(g)\n(Ultra-)High-Pressure ((U)HP) water jetting or blasting\n(U)HP blasting is a dustless surface treatment method using extremely high-pressure water. There are options with or without an abrasive.\nMay not be applicable in cold climatic conditions, or due to surface specifications (e.g. new surfaces, spot blasting).\n(h)\nStripping of coatings by induction heating\nAn inductor head is moved over the surface, causing localised fast heating of the steel to lift old coatings.\nMay not be applicable for surfaces with a thickness of less than 5 mm and/or for surfaces with components sensitive to induction heating (e.g. insulation, flammable).\n(i)\nUnderwater hull and propeller cleaning system\nUnderwater cleaning system using water pressure and rotating polypropylene brushes.\nNot applicable for ships in full dry dock.\nTable 12\nBAT-associated emission level (BAT-AEL) for total emissions of VOCs from the coating of ships and yachts\nParameter\nUnit\nBAT-AEL(Yearly average)\nTotal VOC emissions as calculated by the solvent mass balance\nkg VOCs per kg of solid mass input\n< 0,375\nThe associated monitoring is given in BAT 10.",
