Problem<\/b>
\n<\/span><\/p>\n

Heavy equipment used in marine civil engineering has many components that require grease lubrication. However, due to the harsh working environment, marine civil engineering operations are highly susceptible to issues such as grease emulsification.<\/p>\n

This customer, who carries out breakwater construction and the installation and removal of wave-dissipating blocks across Japan, was also struggling with frequent grease loss in the attachments of their crane vessels. In particular, clamshell buckets and orange peel buckets, which are submerged in seawater during operations, experienced high grease consumption. To prevent loss of the lubricating film, they used expensive grease yet still needed to reapply it every half day.<\/p>\n

We proposed introducing \u201cPremalube<\/a>\u201d to reduce both grease consumption and the labor required for re-lubrication. The results were as follows:<\/p>\n
