Military ships, like other vessels, are constantly exposed to a highly corrosive environment and different types of mechanical stress. This is due to the fact that many of its metallic components are exposed to the elements, salt water and galvanic effects. Protecting them against corrosion is essential.
Naval equipment also suffers from cavitation, impact, and drag, which can lead to loss of efficiency. Consequently, it can lead to loss of efficiency and even equipment failure if it has not been adequately protected. This can also happen even if it is covered with conventional coatings.
The maintenance, repair and protection measures that are carried out periodically on military ships are crucial. Keeping boats in optimal condition also serves to extend their useful life. Routine inspection and repair of military ships reduces the costs of purchasing new parts and equipment. Repairs often need to be done on a tight schedule to meet the ship’s mission deadlines.
Belzona has been involved in various repairs within the military for many years, providing on-site work on vessels while they are under construction, on active duty, or during periods of major refurbishment. Cold applied epoxy compounds or fast curing metal repair compounds. Also, Belzona’s Corrosion Resistant Coatings and Equipment Alignment Fillers not only allow for a quick repair, but also protect the equipment and boat from future damage and failure.
Examples of Belzona applications on military ships
