T
he prototype device was developed by one of Jumbo’s Chief Officers while working on his Master’s thesis. Initial results show that the device is not only faster than existing methods of removing temporary weldings, it is also cleaner for the environment, healthier for users, and improves the appearance of the ship.
Flash rust
While Jumbo’s nine heavy lift vessels are technically and operationally in excellent condition, their decks and hull sides have a decidedly rusty appearance. Known as flash rust, this has the potential to be detrimental
to Jumbo’s reputation for the proper management of its assets. Flash rust is caused by the corrosion of steel particles dispersed during the removal of temporary welded securings, a process requiring the use of cutting, gouging, and grinding tools. The steel and paint particles formed during the removal process can also be harmful to the environment and to human health. Further adding to the list of negative consequences, the removal of the temporary welded securing is a timeconsuming and uncomfortable task for the ships’ crews.
