cofferdam

We may have to rig a cofferdam and the least depth the better for us.

A cofferdam was constructed around the site in the lower reservoir.

On 13 February 1912, the engineers let water back into the interior of the cofferdam.

To divert the river, a cofferdam did not need to be constructed.

The cofferdam was later incorporated as part of Piers 5 and 6.

"What about a cofferdam large enough to go round the whole cruiser?

Three days later, the interior of the cofferdam was full and Maine floated.

A cofferdam was built to intercept the water and stop further erosion.

When the project is completed, the cofferdam may be demolished or removed.

The construction of the cofferdam began in 1985 and was completed in 1987.

Steel sheet piles were driven into the bed around the cofferdam.

Once the caissons were filled, water would begin to be drained from inside the cofferdam.

Afloat again on 29 June, she promptly went down for a third time when the cofferdam failed.

It hardened and made the cofferdam part of the ship watertight.

Her crew had to construct a cofferdam across the main deck to stop the flooding.

The second cofferdam was downstream and prevented water from flowing back into the construction site.

Once the stern was free, water was slowly allowed into the cofferdam.

Due to a structural inadequacy, the cofferdam washed out on October 31, 1970.

A cofferdam is a small space left open between two bulkheads, to give protection from heat, fire, or collision.

Seven workers died during construction, most from drowning as a result of washouts on the site's cofferdam.

To allow for construction without impacting the water supply, a cofferdam was constructed.

The cofferdam is later replaced while the hull sections are welded together again.

The cofferdam enabled the water inside the dam to be pumped out and the foundation built "in the dry."

In such cases the cofferdam is fabricated from sheet steel and welded into place under water.

After the Maine was sunk at sea, the cofferdam was removed.
