Being able to blank off sea inlets and overboard discharges safely and quickly underwater is essential if costly delays or even unscheduled dockings are to be avoided. Our blanks are supplied to ships in service and new builds. Their design are also suitable for semi-submersible oil rigs and other offshore structures that cannot easily be brought to the surface. FPSO's that are sometimes on station for 10-25 years rely on this kind of technology to enable them to remain on station.


Thousands of our blanks have been supplied to literally hundreds of vessels and individual blanks have been fitted and refitted many times without one recorded failure. The design incorporates a minimum safety factor of 4 and all blanks may be inspected for class approval on request. All our hull blanks are quality checked to the highest standards.
