Plugging & Blanking

“ Your Performance is our Business ”

Underwater Plugging or Blanking of Seachest, inlets and overboard discharges safely and quickly is essential in order to avoid costly delays or unscheduled dry-dockings. Underwater blanking and plugging operations are also suitable for semi-submersible installations and other offshore structures that cannot easily be brought to a docking facility. FPSOs that are on station for 10 to 25 years rely on blanking technology to remain in service and in class.

NEREUS SUBSEA has revolutionised the methodology for plugging and blanking which can be easily fitted by our experienced divers. Our design incorporates an adequate safety factor with all plugs and blanks being quality checked to the highest standard. Many of the blanking systems carry class approval from the major classification societies.
