Hull aperture blanks for in-water valve replacement

Sea valves can be opened up inboard for inspection, maintenance or repairs, whilst the vessel remains afloat, by means of blanking apertures. Our specially designed blanking apertures have the ability to blank off sea inlets and overboard discharges safely and fast by our divers.

We always have a large stock of hull aperture blanks available in order to assist you as soon as possible in emergency cases.
