Shipyards around the world regularly call Polygon when they need help with ship maintenance repairs. Weather conditions often make it difficult to perform many of the necessary ship repairs to ensure that vessels continue to operate. Painting, steel replacement and corrosion control are all impacted by the high levels of moisture that can be found on board an ocean going vessel.
Whether it is a military ship, oil freighter, barge or cruise ship, the ability to make repairs in a short period of time is a must. Polygon state of the art climate control equipment will enable the ship yard to repair or repaint at any time of the year. Even in the harshest winters, Polygon unique blend of dehumidification equipment will keep the condensation in check allowing blasting while large indirect fired heaters create the correct temperatures for coatings to cure.
The control of condensation on the walls of the ship’s hull below the water line is of the utmost importance when attempting to recoat steel surfaces. Warm moist air coming in contact with the cold steel surface will produce moisture that can negatively affect the blasting, application and curing of most maintenance coatings. Lowering the dew point in the space is a simple and cost effective method for allowing this work to be completed.
The use of Polygon temporary desiccant dehumidifiers and heaters provides the necessary components to allow all ship repairs to be possible throughout the year. Polygon provides a completely controlled climate which ensures you can conduct planned maintenance procedures irrespective of weather conditions. Corrosion will be held halted, coatings will be painted in the optimum conditions and the life expectancy of the overall paint system will be lengthened.
In order to ensure that the equipment is tailored specifically to each ship hull, the following detailed information is necessary:
Only when this information is compiled and analysed can the suitable equipment be selected. Polygon personnel can then engineer the equipment for specific applications to meet the desired specifications for the project.
Polygon technicians service and check the equipment, ducting and ancillary items to be used at the site before delivery. After delivery to the site, the equipment is then placed in a designated area, positioned close to a power supply and set up to maximize the safe operation of the unit.
Polygon state-of-the-art desiccant dehumidification systems are utilised to deep dry the ambient air which ensures that the dew point temperature in the hull is lower then the steel temperature so as to eliminate condensation. Temporary cooling and heating equipment can be provided to control temperature conditions within the vessel when needed. Polygon provides a turnkey solution with well engineered equipment offering around the clock service that is unmatched in the industry.
