ABSTRACT:
A lipped mouth seal structure with inflated lips mounting a sponge rubber type seal engaging the side of a large container tank or ship such as an oil tanker around an area of puncture or rupture with the lips generally rectangular about an area enclosed thereby. The lips and the area within the lips is spanned by a leak proof flexible membrane overlying the back sides of the lips. The lips underlie, at the top and bottom of the seal structure, transverse cross brace bars retained in rearwardly extended sleeves of the seal structure. The lips are in the form of inflatable rings of rubber (natural rubber, synthetic rubber or rubber-like plastic) mounting the resiliently deflectable sponge rubber type seal on the front ship facing side of lips with the sponge rubber seal along with the inflatable rings resiliently deflectable to conform to ship outer surface irregularities in providing sealed containment about a ship skin rupture opening. Vertically oriented straps overlie the backs of the opposite side sections of the inflatable rings pass through the uppermost and the bottom transverse cross brace bars to strap end to cable connectors and with the straps passed through individual vertically extended sleeves on the back of seal structure between the upper and lower transverse cross brace bars. Cables extending from a winch structure on the deck of a ship extend on one side to connection with a top cable connection and on the other side down under the ship and then up to the bottom cable connectors on the seal structure.
