A socket assembly is adapted for retrofit installation within the deck of a vessel. The socket assembly reduces/eliminates the risk of introducing induced stresses into the socket and/or deck during the retrofit installation welding process by providing a cup-shaped body with lashing fixture, a ring secured about the periphery of the body smaller than an opening in the deck, and a securement leg extending downward from the underside of the body with an engagement wall surface offset from a centerline of the body.
