Preparing process of steel surfaces of ship's ballast tanks - Applying the resolution MSC 215 (82)

Applying the resolution MSC 215 (82) in the ship hull production (area of ballast tanks) brought an implementation of new processes and procedures in preparation of steel surfaces before painting a section, ballast space, and also in delivery of them to the representatives of the classification societies, ship inspectors and authorized inspectors of colour. In ship’s hull production, surface preparation is a demanding technological work operation which begins with primary surface preparation (preparation of plates and sections for dyeing workshop with protective coating) and continues with the preparation of steel before painting of sub-assembled sections and blocks according to ISO 8501-3 grade P2 . The surface preparation or additional surface preparation work, according to the above mentioned standards, require some additional technological time, a new human resources which in the end can significantly affect the ship's hull building time and the final price of the vessel in its entirety. Shipyard has to apply control process over surface preparation during the process of drafting and construction of hull and provide in this way the impact on production costs, reduce them to a minimum at each stage of the production process, respecting the norms and criteria for processing, quality control and hull building schedule.
