Technology of Corrosion Plugging Tooling for Ship Cabins

An FPSO (floating production storage off loading) was being put into use for nearly 20 years, and the corrosion and thinning of its cabin bottom plate and wall plate were serious. An investigation found that some individual ballast tanks of the ship (FPSO) had problems such as corrosion and leakage of the L-shaped transverse section roof (the bottom plate of the oil tank), corrosion and leakage of the transverse welding seam of the wall plate, corrosion and leakage of the vertical welding seam at the intersection of three tanks and so on. For the L-shaped cross section top plate, the on-site personnel processed a set of plugging tooling with four bolts and a glue injection groove to provide support for weak points and prevent the leakage problem from worsening. In view of the leakage problem of the welding seam of the cabin wall, a set of isolation box was made to prevent the leakage of liquid from spreading. In view of the leakage of the vertical weld at the intersection of the three cabins, a set of glue injection boxes that could be pasted and welded were produced to achieve leakage prevention under production conditions. The above measures not only ensured the normal production of the ship itself, but also prevent the deterioration of the leakage problem and the occurrence of oil spill environmental protection accidents.
