Sealing Dry Docks - The Importance of Polyurethane Grout


A dry dock is a spectacle in itself even without a vessel supported in its basin; its sheer scale, intelligent design and engineering capabilities all combine to create an impressive site that makes water bound voyages possible.

A dry dock can be flooded with and drained of water, allowing a load to be floated in, which is then left supported on an exposed dry platform when water is drained from the container. This allows maintenance and repair to be carried out, including the removal of barnacles and rust, which cannot be reached or seen below the waterline, when a vessel is afloat.

A dry dock is essential when it comes to maintaining all parts of a vessel; as well as the restoration of ships; dry docks often act as the birthplace of a fully formed vessel, the final stage before it sets sail on its maiden voyage, where it is released from a nurturing environment and introduced to an independent life upon the open water.

The rehabilitating environment of a dry dock needs to be kept dry so that staff can operate cranes and vehicles. Leaks in a dry dock lead to a less than ideal environment and can compromise the efficiency of the work carried out and an increased fill time. The structure of a dry dock is often subject to hydrostatic pressure, when empty, which is the pressure at a point in fluid at rest due to the weight of the fluid above it. This means that construction joints must be continuously monitored to prevent leakage.

The world is home to many dry dock locations, which become features of the landscape, drawing attention from tourists and locals as major destinations. An example is Dubai dry docks, one of the largest in the world, employing more than 5000 workers, who have repaired and maintained 5000 vessels and oil rigs since 1983. Disused dry docks can also act as standing museums, displaying relic ships in all their glory, so that their entire shape, including huge propellers usually hidden by the water can be shown off.

Dry docks have helped shape some of our most impressive and famous vessels, including the Titanic. Her dry dock was used to paint the hull, fit the propellers into position and apply some final fixtures. Titanic’s Thompson dry dock is now a tourist site in Belfast, attracting considerable interest, charging £50 per view. At 850 foot long, the dry dock could be drained of its 24 million imperial gallons of water in 100 minutes and supported the Titanic’s masterful structure, which took 500 men 5 years to complete. The historic site marks the beginning of Titanic’s infamous maiden voyage.

As its name states, a dry dock should be dry; SealGuard’s fast acting polyurethane grout has been used on dry dock projects for permanent solutions to water leaks, which is a fundamental part of producing quality seaworthy vessels. Our polyurethane grout gets straight to the heart of a leak, so that a dry dock remains water tight and fully operational.
