4. Application of the metal repair material to restore the pitted sections

Application Situation
Built in 1946, PS Waverley is one of the world’s greatest historic ships and the last sea-going paddle steamer in the world. Listed among the National Historical Fleets records, the 70-year-old vessel still operates passenger excursions around the British coastline thanks to tireless maintenance efforts.
Application Method
In order to combat the high temperature environment, Belzona 1511 (Super HT-Metal) was used to rebuild the pitted areas, able to be hand-applied and solvent-free. Once cured, the metal repair material was machined down to be flush with the surrounding areas. This application was completed using a modified version of ENC-4 system leaflet. 
Belzona Facts
Attempts had been made to repair this previously, however similar defects had arisen. Therefore, Belzona was recommended as a viable option by Engineers from a nearby ferry company, who had successful experiences with Belzona’s polymeric solutions. Any maintenance to the Waverley takes place out of season, in Winter, as to avoid any downtime during peak times. The Engineers were impressed how the application took under two hours to complete. Each individual steam cylinder is accessed every five years; therefore, any further applications of this type will be reviewed within the next maintenance window.
