ABSTRACT:
A sea chest cover for providing access to the sea chest of a ship. The sea chest cover is fabricated essentially entirely of one or more viscoelastic materials, preferably either polyethylene or polyurethane. Fabrication of the sea chest cover from a viscoelastic material reduces or eliminates corrosion and erosion problems. It also minimizes marine organism and ice build-up. The result is a reduction in the expense associated with maintaining such covers. The fabrication of the sea chest cover essentially entirely of viscoelastic materials minimizes the weight of such components, thereby making handling and maintenance easier. The sea chest cover is either pre-formed to a shape conforming with the shape of the ship's hull in the area where the sea chest is located, or it is sufficiently flexible to be placed into such conformance. The sea chest cover of the present invention may be formed as a unitary piece or as a plurality of removably connectable parts.
